Coloring plastics at the press is one of the most functional, value-added features a molder can impart to a molded product. Self-coloring not only improves aesthetic properties, it can also Excellerate UV stability and make processing easier. Also, adding color at the machine is almost always less expensive than purchasing precolored material from a supplier.
There's just one catch. Once the color system has been incorporated into the polymer matrix, it becomes an integral part of the material and may alter its engineering properties as well as its processability. As a result, it's important to be aware of some of the common problems involved with melt-coloring plastics and how to avoid them.
Generally, aesthetic flaws can be attributed to three different causes: equipment (machine, mold, ancillary equipment), molding (process), and design (part and tool)/formulation (base resin and colorant). In some instances, the flaw may be the result of problems in more than one category, but generally, there is always a predominant issue. Similarly, some problems may have more than one symptom, so several different "problems" may be showing up in parts that have the same root cause, which calls for the same corrective action.
When troubleshooting aesthetic problems in molded parts, it's important to begin with an open mind. Since successful molding is an interdependent combination of machinery, labor, material, and design, troubleshooting is often more complicated than people initially expect.
Identifying the Problem
The first step in determining if the flaw is caused by a molding- or colorant-related problem is to inspect parts visually to determine what the problem looks like. Some flaws are very distinctive and quickly lead you to their root cause. Others are less distinct and may be caused by a number of factors that fall into several categories. Consequently, some basic troubleshooting and root-cause/corrective-action work is required. The table with this article provides a list of common aesthetic flaws that could involve colorant and their most probable causes.
The next step is to find out when and where the flaws are being reported. Flaws that show up immediately upon molding require one approach to troubleshooting-for instance, processing and equipment issues are easier to check at this point. In this case, the troubleshooting process might start by asking the following questions:
However, field failures that occur after months or even years will suggest a different starting point-a focus that begins with either part design or formulation:
Regardless of the simplicity or complexity of a molding project, good documentation practices should be in effect and followed diligently by all team members. Processing parameters should be noted throughout. Not only will this practice help molders stabilize their process and create good parts faster, it will also provide a baseline for reference should the process drift and problems arise.
Common Sense- Often Uncommon
The best way to begin troubleshooting an aesthetic problem in which colorant and/or special-effects packages are involved is to rule out the colorant package as the source of the problem. This is done by running uncolored (natural) material through on the same process settings to see if the problem recurs. If it does reappear, then it's likely that the problem is not caused by the colorant package, although the base resin could still be part of the problem. If the problem disappears, then the colorant package is the proper place to begin your investigation. It's important to remember that aesthetic issues may exist that are difficult to see without color. In other words, a colored background will frequently magnify aesthetic problems.
While it is outside the scope of this article to cover the entire process, one thing that should be mentioned is that proper troubleshooting requires a sensible, methodical approach. Unless a Taguchi design of experiments study is being conducted, only one parameter at a time should be changed, and its effect should be carefully evaluated and documented. Then the parameter should be returned to its baseline setting before another parameter is changed.
While the following guidelines involve colorant-related problems, we will also touch briefly on processing, equipment, and design issues, indicating areas of concern that can affect colorant and/or aesthetics. If the troubleshooting process indicates that one of these categories is a likely cause, then there are a number of good resources, both human and written, that can and should be consulted for further help.
As with any manufacturing process, molding a quality product consistently requires proper equipment, design, material, and processing procedures. The following list of considerations are provided as general guides when beginning to troubleshoot aesthetic problems.
1. First, check the following four equipment areas.
Screws/nonreturn valves. In most cases, a general-purpose screw will work well with colorants, depending on the letdown ratio, chromaticity, and base resin used. Although it's usually not necessary, a growing number of injection molders are using mixing screws to aid in color distribution. Processes with high throughput, short cycle times, and large shot sizes or those that use difficult-to-color resins will often benefit from this type of screw.
As with screws, selection of non-return valves is often resin-specific. Ball check valves are more shear intensive and can aid in color distribution, although this method can prove problematic when processing parameters such as screw speed, backpressure, and barrel temperatures are pushed close to the base resin's limits, leading to both colorant and resin degradation.
Screw and barrel wear. A worn screw or barrel-regardless of the design-will inhibit mixing, causing a loss in plasticating quality and therefore color distribution.
Barrel capacity. As a general rule, using more than 60 percent of the barrel capacity with a GP screw is considered to be pushing the processing envelope for good color incorporation. Of course, this is cycle-time dependent. The barrel's L/D ratio is also important. For example, shorter barrels (18:1) are less conducive to a good mix, while longer barrels (24:1) provide a longer mix environment, but also longer residence time. It's important to keep an eye on material residence time, because excessive residence can degrade either the base resin or the colorant, or both, while insufficient time in the barrel may lead to distribution issues.
Colorant handling and dispensing. One of the keys to successful color processing is an accurate blending/distribution of colorant and base resin before both enter the molding machine. When blending equipment is used, production personnel must be aware of proper operation, calibration, and maintenance. If the equipment is not properly calibrated to the process, any money saved by coloring the raw materials will be lost in wasted product.
For solid (salt and pepper mix) colorants, there are many different options, such as drum tumblers or auger mixers. For blending concentrates and powders at the machine, either volumetric or gravimetric feeders are used. Volumetric feeders are both less expensive and potentially less accurate than gravimetric types because they feed colorant based on speed vs. time. Gravimetric feeders weigh and blend each component in the mix. For liquid colorant, special volumetric pumps are typically used to handle the color accurately and neatly. (See the sidebar on p. 87 for definitions of common colorant-system formats and their functions.)
2. Tooling design can also impact aesthetics.
Gates and runner systems. Proper gating and runner types should be considered at the design table. It's important to remember that additional heat generated by a hot manifold or pin gate during injection fill can affect the integrity of the color. If it's known ahead of time that such tooling is being used, a colorant supplier can formulate the color package differently.
Knitlines. Anticipating aesthetic issues during the early design stage is very important, especially if knitlines are a factor. When moldfilling analysis or experience indicates knitlines are likely, color formulation changes can be made with certain resin families that will Excellerate the appearance of knitlines. Of course, this issue is more easily resolved during the early stages of part and tooling design.
Mold texture. Also an important consideration during the design stages is mold texture, since it can affect how the eye perceives color. The presence of gloss and/or texture in the tool can make what would otherwise be an exact color match appear very different. Gloss should be considered in relation to both the mold and resin being processed, since some materials naturally have higher gloss.
3. Take a good look at part design.
Color/special effects. It's important to understand that a joint blessing and challenge of molding color and/or special effects is that the color package may accentuate design or molding problems that are already present in a part, such as knitlines, slight sinks, or stress-whitening marks near the base of a snapfit. Taking color back out and running the part in natural resin may appear to make the problem disappear, but in reality the problem, if it is a molding or design issue, is probably still there, and just not as visible.
The problem will be accentuated in chromatic colors and high-gloss designs. So if it's something that can otherwise be lived with, slight design modifications may solve the problem. On the other hand, certain problems, like stress-whitening marks, can often be hidden by the correct use of color or possible reformulation.
When integrally colored, molded parts of dissimilar materials are mated with other molded or painted parts, they must often match in color, gloss, and texture. Here, it's important to work closely with the resin and color suppliers to ensure that the parts will match as closely as possible when they are new and that they will fade at the same rate throughout the lifetime of the assembly.
Bosses/ribs/knitlines/parting lines. Wherever there is a flow interruption in the part design-from bosses, ribs, or even converging flow fronts on multiple gated parts-there is a strong possibility of sink marks, knitlines, and compromised mechanical integrity because knitlines are always weaker than the surrounding resin. Since the orientation of the material in these areas shifts, the refractive index across this region of the part will also shift, posing aesthetic challenges for many special-effects packages. Therefore, these interruptions should be designed into nonvisible faces and noncritical areas of the part.
4. Take these processing tips to heart.
Screw speed. For color processing, a slower screw speed is usually better to avoid shearing and burning the colorant and to ensure proper color distribution, cycle time permitting.
Backpressure. Higher backpressure promotes more thorough mixing, especially with a GP screw, again, if cycle time permits. A maximum value of 300 psi (2 MPa) is generally recommended by machinery OEMs.
Resin temperature. Higher melt temperatures also promote better mixing, as long as the processor is careful not to begin melting too early in the feed section of the screw, although this too can be resin dependent.
5. Be aware of these colorant and formulation issues.
Resin and colorant compatibility. The melt index relationship between the base resin and color are very important and should be considered early in the design. Additionally, certain pigments react with particular resins to a greater or lesser degree.
For instance, some organic pigments tend to dissolve and disappear (or change color) in styrenic polymers. Similarly, many dyes tend to change color or disappear in nylon polymers, which are weak reducing agents that effectively destroy the chromophore component of the dye that provides color. Additionally, except in special cases, dyes are not recommended for use in olefins because of very limited solubility and a potential for color migration (crocking). Further, dyes can act as a plasticizer in some materials, reducing thermal properties or even reacting with the resin itself to produce various effects.
Phthalocyanine (phthalo) pigments can be problematic, since they can act as nucleators, causing often uncontrollable shrinkage and warpage problems in crystalline resins. Fluorescent dyes also can pose problems in certain environments. They lack thermal stability for use in many engineering resins, they chemically react with nylon, and they lack UV stability for use in most outdoor applications.
A final category of problems is often found with polymer blends and alloys. There can be phase boundaries between the various components of these materials that can cause light scattering and a resulting milkiness. Hence, obtaining chromatic colors can become a costly undertaking due to the large amount of colorant that needs to be introduced to counteract the milkiness-often at the expense of economic concerns and critical physical or mechanical properties.
Carrier specification. The specific carrier for the color and its flow properties vs. the base resin play an important role in color distribution, and must be considered during the initial design. The carrier should melt in the late-feed or early-transition sections of the screw to ensure proper distribution of the pigment or dye in the mix. If the carrier has either too high or too low a melting point, the colorant will not be properly distributed in the melt, and finally in the molded part.
Other additives. Special additives for the colorant package can help with some color-related problems. However, these ingredients are normally not incorporated until processing efforts have failed, primarily because they add cost that may make the end product less cost-effective.
Grade can make a difference. It's important to remember that not all resin families or even grades within the same family are interchangeable with a given color package, let alone with different pigment or dye packages in the same chemical family. Further, since most colorant suppliers custom formulate their packages to a specific resin grade by a particular manufacturer, if the resin supplier is switched after the color package has been formulated, it should be retested.
A good example of this is the fairly wide fluctuation that can be seen in the natural color of polypropylene, which can range from a yellow-white to a gray-white shade, depending on the quality and quantity of filler used.
An Ounce of Prevention
Like so many other problems in life, colorant issues are far easier to anticipate and prevent than to cure once they've occurred in molded parts. If color is important to the final performance of an application, then it should be designed in from the start via simultaneous engineering. To ensure the colorant package is properly formulated for the application, provide the color formulator with all available information on both the application and its material targets as soon as they are set.
If any of these specs change during the latter stages of the design process, inform both the resin and colorant suppliers. Changes may require a new formulation. Don't hesitate to call on the colorant supplier to analyze, retest, and reformulate a color formulation to make sure it will be suitable in the end-use environment.
It's also important to inform the colorant formulator of your equipment setup, in case you need to make changes in order to optimize the resin/colorant/throughput requirements of a particular application. Finally, watch your process parameters and once the process has stabilized, note any sudden changes that may signal the beginnings of a problem.
Special care is needed when self-coloring engineering resins because a significant portion of their perceived value-and therefore cost-lies in their superior physical, mechanical, and aesthetic properties, which can be sensitive to even small compositional changes. The more important color is in a given application, the sooner the colorant supplier should be involved in the design process.

Microsoft has worked hard to add tons of inbuilt troubleshooting methods in Windows 10. There is one for almost one for every standard error in Windows 10. Going ahead, the team has added Recommended Troubleshooting. It allows Windows 10 to fix many critical problems on your device automatically. In this post, we will learn how to turn on or off Recommended troubleshooting in Windows 10, should you feel the need to do so.
Microsoft Diagnostic & Feedback data offers two settings. Basic and Full. If you want to turn off recommended troubleshooting, then the only way out is to stop it from collecting complete data from your computer. So, to turn it on or off, you can choose to switch between them.
You should now see a warning message which would say — Share Full Diagnostics data to get additional troubleshooting recommendations.
The message clearly states that Microsoft will only offer recommended troubleshooting based on the Full Diagnostic data which it collects. None of the advanced troubleshooting will make it to your computer.
If you are comfortable with the Registry or want to turn it on or off for remote computers, here are the changes you need to make.
Open the Registry Editor by typing regedit in the Run prompt and hit Enter.
Check if you have WindowsMitigation key, if yes – good! If not, right-click the left pane, and create a new key with the name WindowsMitigation.
Now under that, create a DWORD UserPreference.
Double click on UserPreference to edit the value. Set Value to 1 (On) or 3(Off) and exit.
Restart your computer to see the changes.
The functionality can look into the error logs sent back to the Microsoft team, use an algorithm to set up a solution for you. They are nothing but Diagnostics and Feedback data which Windows collects and sends back to the Microsoft team. The settings of which are available under Settings > Privacy > Diagnostics & feedback.
The recommendations are only visible when you are connected to the internet. Otherwise, it will leave a warning about the same.
It’s a great move from Microsoft, but we will have to see how it works for most of the consumers.
If you have a learner's permit, you'll need car insurance — but not necessarily your own. Drivers who are learning the rules of the road can join their parents' policy. But drivers who can't or don't want to join their parents' policy still have options.
Every insurance company has different rules about when learners must be added to a policy, and many offer discounts to offset the high costs of insuring drivers with learner's permits.
Even with fewer driving privileges, learner's permit drivers must be insured. They're just as vulnerable to accidents and need the financial security insurance provides.
In most cases, learner's permit drivers are teens living with their parents. These young drivers are generally covered by their parents' policy when they receive their learner's permit and don't need to buy their own policy.
However, insurers take different approaches to young permit drivers. Policyholders may have to list every member of a household who has reached driving age on the policy. With other insurers, you won't need to do this until your young driver has a license.
For example, if a young driver in your household has a learner’s permit, Geico requires you to list the driver on your policy. As long as the young driver only has a permit, your policy premium will not increase. Once the young driver obtains a license, Geico will factor them into your policy rate.
Reach out to your insurer and see how they handle car insurance for permit drivers. Don't skip this step. If you don't properly list drivers as your insurer requires, then you may have to pay out of pocket for damage after a car accident.
The good news? Insurance companies usually don't increase rates until after a student driver receives their license. At that point, rates tend to significantly increase. But there are still ways to get cheap car insurance for teens.
Out of every age group, teens are the most at risk for car accidents. That's especially true from ages 16 to 19, according to the Centers for Disease Control and Prevention.
Because teen drivers pose such a high risk, adding them to an insurance policy increases rates significantly. The cost of adding a 16-year-old driver to a six-month family policy can range from $1,293 to $4,831.
However, those rates may vary significantly based on the age and gender of the teen driver being added to the policy. Young male drivers are more likely to engage in risky behaviors and are more likely to be killed while driving than young women. This means a family's policy rates will likely increase more when adding a male teen driver than when adding a female teen driver.
Many insurers offer discounts to help families manage the high costs of insuring their teen driver. Ask your insurer if these discounts are available to you:
In addition to asking for discounts, families can also adopt other money-saving strategies. For instance, driving an inexpensive car can keep premium costs down because it costs less to repair or replace a cheaper car.
Parents and teens should also shop around for the best deal. While it's tempting for parents to default to their own insurer when adding their teen child to a policy, other companies may offer better rates and help families save. See this milestone as a chance to re-evaluate your options and choose the one that best suits your family's needs.
Adding permit drivers to a family policy might be the most common way for learners to get insurance, but it's not the only approach. You can buy a car insurance policy just with a learner's permit. Once you have that insurance policy in place, you can also purchase and register a car in most states — even if you are only 16 years old.
While this approach gives 16-year-olds a good deal of independence, that independence comes at a cost. A new driver at this age pays an average of $5,944 for a six-month plan if they purchase their own insurance. By contrast, a new driver added to their parents' policy may pay as little as $1,293 — a $4,651 difference.
The single best thing you can do to lower your expenses as a young driver is to stay on your parents' insurance policy.
However, not all learner drivers live with their parents. Many people learn how to drive much later in life and can't be added to a parent’s policy.
You still have options if you're in this situation. Permit drivers who live with a spouse or significant other can sometimes be covered under their plan. Be aware that married couples may receive better deals than unmarried couples, and unmarried couples may see their rates go up when a permit driver is added to the policy. Reach out to your insurance company and see which options are available to you and your partner.
If you are a permit driver who lives alone, you may find it difficult to find an insurer that will cover you until you get a license. Many national insurers do not offer insurance to first-time learner's permit drivers. Instead, contact smaller local insurance providers and explain your situation. You will likely pay more, but the situation is not without precedent.
For new drivers, getting a permit is an exciting time. Obtaining auto insurance coverage is a crucial first step to new levels of responsibility and freedom.

Android Auto is one of the best apps you can get for your car. It’s already available on your Android phone, and if your car supports it, you have a quick way to access Google Maps and music apps, make and receive calls, and reply to messages (with your voice) while you’re out and about. Android Auto makes life much easier on the road. When it works. Unfortunately, one of the most common phone problems users complain about has to do with Android Auto. Here’s a look at some Android Auto problems and how to fix them.
Read more: What is Android Auto?
Editor’s note: Some of these steps were put together using a Pixel 7 Pro running Android 13. Some steps might be different depending on your hardware and software.
C. Scott Brown / Android Authority
Let’s start with the basics. Not all phones, cars, or stereos support Android Auto. There are also location restrictions, so you won’t be able to use Android Auto from unsupported countries.
Android Auto requires that your phone runs at least Android 8.0, and that’s for a wired connection. Those wanting to use Android Auto wirelessly will need an active data plan, 5GHz Wi-Fi support, and at least Android 11. There are some exceptions. Google and Samsung phones can get away with Android 10. Samsung Galaxy S8, Galaxy S8 Plus, and Note 8 handsets can do with Android 9.0.
You can download the app from the Google Play Store. For any phone with Android 10 or newer, Android Auto is already baked into your phone’s Settings menu.
Let’s move on to cars and stereos. You can check the car and third-party stereo compatibility on Google’s official list. The list of vehicles shows the oldest model that supports Android Auto, and it’s safe to assume that accurate cars from these manufacturers support the service. Most accurate releases also support Android Auto Wireless. But it’s best to check with the seller first to ensure the vehicle you are interested in supports the service.
Unfortunately, if the car or stereo doesn’t support Android Auto, you won’t be able to use it on just your phone. Google removed the Android Auto for phone screens feature with Android 12. You can still download and install the app on older devices. But with any phone running Android 12, you will have to rely on the Google Assistant Driving mode.
Android Auto availability also depends on your location. The app is available in 46 countries, and not all of them support Google Assistant while using Android Auto. You can find the complete list of supported countries here. Scroll down to the FAQ and look for Is the Android Auto app available in my country?
Similarly, if you live in an unsupported country, there isn’t much you can do other than wait (very patiently).
It’s one of the most common troubleshooting tips: restart it! I’ve found the same applies to Android Auto not working. First, try unplugging your phone and plugging it back in. This often fixes the problem. If that doesn’t work, turn the phone off and back. Lastly, you can try turning the car off and on again.

Phone makers make it easy to transfer files, apps, and settings from an old phone to a new device with apps like OnePlus Switch, Samsung Smart Switch, and more. Users say that using these methods to set up their new phones often causes problems with Android Auto. There are a couple of solutions we can recommend.

A lot of Android Auto connection problems occur because of a faulty cable. If you see frequent disconnections or Android Auto isn’t loading at all, the cable might be the problem.
C. Scott Brown / Android Authority
You don’t have to worry about carrying a cable around if your car supports Android Auto Wireless (check with your car manufacturer). However, plenty of users face problems with connecting to the wireless feature.
If you are facing problems with Android Auto Wireless, users say that setting up a wired connection first seems to do the trick. Plug the phone in with a cable and set up Android Auto. Once the connection is established, Android Auto should work the next time wirelessly. Turn off your car, unplug the phone, and try to use Android Auto Wireless.
Some users say that while Android Auto seems to connect and the Google Assistant works as expected, they see a blurry, pixelated, or blank screen.
C. Scott Brown / Android Authority
With a mix and match of phones, cars, and third-party stereos, it’s difficult to pinpoint what is causing Android Auto problems and offer solutions beyond general troubleshooting. Google continuously updates Android Auto and fixes issues as they come up. You should also report any problems you face to let Google know.
Open the Android Auto settings page and tap on the three vertical dots at the top right corner. Go to Help and feedback > Send feedback. You can also post your problems on the Android Auto community page.
Along with this recognition, the UNG Gainesville Campus received a $25,000 grant to increase support for adult learners. The grant was subsequently renewed in 2012 for an additional $25,000. The intent of the grant was “to galvanize [adult Georgians] to change their situation, thereby boosting the state’s economic growth” (University System of Georgia).
As part of this same initiative, in March 2011, the University System of Georgia’s Office of Military Outreach awarded the UNG Gainesville Campus the Soldiers to Scholars grant enabling the university to better serve military personnel in its service area. With the ALC grant funds, institutional funds, and faculty/staff support, the University of North Georgia has continued to grow its support for veterans and adult learner students.
With a growing number of both student veterans and adult learners, UNG created the Center for Adult Learners & Military (CALM) in 2012 in an effort to better serve these non-traditional student populations. CALM was renamed in January 2017 to Veteran & Adult Learner Programs (VALP).
In August 2020, VALP and Orientation and Transitions Program (OTP) merged to form a new department: Nighthawk Engagement and Student Transitions (NEST). This merger has increased the number of dedicated staff trained to serve Veterans and Adult Learners. NEST is now able to provide a dedicated team of staff members for Veterans and a dedicated team for Adult Learners. Having specific staff dedicated to each of these programs allows NEST to continue all previous VALP programs with an addition of new programs better geared toward each specific population. These programs will help Veterans and Adult Learners connect, prepare, and navigate their college career.
NEST is the point-of-contact concierge for the Veteran and Adult Learners and provides advisement as requested, ACE transcript reviews, portfolio counseling, career advisement, and mentoring. NEST also works with faculty and staff by providing them training opportunities concerning Veteran and Adult Learners.
For English learners, acquiring language proficiency opens the door to thrive across all subjects. However, learning a new language can be a long, difficult process that requires courage, resilience and trust from students who initially might feel vulnerable and out of place.
Schools are challenged by the growing number of English learners in their classrooms, with some districts having as many as 100 different native languages spoken by their students. While many regions of the country are equipped to integrate these students, there is still a struggle to find the best ways to support English learners and their caregivers.
It’s crucial for teachers to create classrooms that are safe places for students to try, experiment and get meaningful feedback that allows them to make sense of what’s going on around them. The first step requires developing a more comprehensive linguistic profile of students.
Standardized tests are an important part of a linguistic profile, but we need to also consider a student’s background and exposure – what languages they speak at home and with whom do they speak those languages – in order to build a more comprehensive picture. Understanding the linguistic and cultural profile of your students will enable you to select the most appropriate evidence-based strategies and customize them to meet individual needs.
To effectively set each student – regardless of their native language – on a path toward achievement in the classroom and overall academic success, consider these five key strategies:
In the classroom, the most fundamental aspect of a successful teacher is establishing a culture of trust. However, for some students, this can be more of a challenge because English is not their native language. By developing linguistic profiles that go beyond standardized testing and leveraging these five key strategies in the classroom, teachers can help English learners overcome hurdles and achieve in the classroom.

Roku is a prevalent name in the home streaming world. The company offers tons of streaming sticks and smart TVs, and it has around 70 million monthly active users in the USA as of January 2023. Plenty of you are using the platform, so we can understand how big of a deal it can be whenever Roku isn’t working. What do you do if your Roku doesn’t work? We can deliver you plenty of troubleshooting tips. Here are the most common Roku problems and how to fix them.
Also read: Which Roku device is right for you?
Editor’s note: Steps in this article were put together using a Roku Ultra running Roku OS 11.5.0. Keep in mind steps might differ depending on your hardware and software version.
It’s not common, but sometimes Roku’s services go down. You should first check if Roku’s servers or services are having issues. You can use a website like DownDetector.com, which collects user reports to determine whether a service is down or not. It even has a map feature to determine if an outage is local or widespread.

There are many reasons why your Roku may not be working. We can’t always find the direct problem, but we can tell you that most small issues are usually fixed with a simple restart. deliver it a try!
Edgar Cervantes / Android Authority
It can overheat if you set your Roku on top of another device or in a confined space. It shouldn’t be common, but you will see an on-screen warning if your Roku is overheating. Some Roku devices also feature an LED light that will light up bright red when it overheats.
When you see the on-screen warning or LED light, immediately shut your Roku off and unplug it. Wait ten minutes or longer before reconnecting your device and power it back on. If the problem persists, turn your Roku back off and unplug it. You may have to contact Roku if you can’t find a way to cool your device down, which may indicate more significant hardware problems.
Talking about a red light, it can identify more than overheating issues. You may also run into a problem where your Roku isn’t getting enough power, indicated by a red LED or on-screen warning. If you’ve plugged your USB-powered Roku device into your TV in a closed loop, that may cause your problem. Some TVs come with USB outlets that deliver less power than others, and some aren’t meant to deliver power at all.
The easiest way to fix this Roku problem is to plug your USB into the power adapter, which should come in the original box. Roku designed its adapter to deliver the correct power level, so trust the hardware! If you still have problems, try moving the power adapter to a different outlet or power strip.

Most Roku products ship with simple IR remotes, but newer units can get Wi-Fi models. These are arguably better, but they can also complicate things a bit. Sure, they let you point anywhere with good results, but you may have connection problems. Most of these issues should be easy to fix on setup, but here’s what you can try if not.
Unfortunately, IR remotes still require direct lines of sight to your streaming device. You’ll have to move all obstacles between yourself and your streaming device. Make sure to check your line of sight from anywhere you like to sit in front of your TV.
You can also replace the batteries in your IR remote for a stronger connection. The IR blaster works like a flashlight and is only as good as its beam strength. A fresh set of batteries should help fix this type of Roku problem.
Roku’s Wi-Fi remotes are slightly more complicated but are also significantly more powerful. You can try the battery trick we mentioned above, but it can also help to restart or re-pair your remote and streaming device.
This should restart both components but can also make your remote lose connection with the device. Here’s what you can do if this happens.
Note: If you’re unsure which remote you have, remove the battery cover. If you have a Wi-Fi remote, you’ll see a tiny pairing button, which will be absent from IR remotes.

Are you still having problems with Roku not working? Maybe it’s time to start looking outside your Roku hardware. You may be having internet problems. To find out, grab another connected device using the same Wi-Fi network. This could be a smartphone, tablet, or computer. Check if your internet is working on other devices. If other devices don’t work, you know what the problem is.
Check if your router and modem are operating correctly. You can try to reset them. There’s usually a dedicated restart button on these, but you can also use the universal method of unplugging the router, waiting a minute or so, and then plugging it back in. If a simple method for fixing your internet doesn’t work, you should probably call your internet service provider for help.
Roku also has a dedicated tool for checking your internet connection.
You should see Excellent, Good, Fair, or Poor indicators in the About section. If you have a Fair or Poor connection, you may want to try to Excellerate your connection.
If your Roku device has an Ethernet port, try connecting to the internet that way to test if the problem comes from your Wi-Fi.

Audio and video problems on your Roku can come from several issues. It could be a problem with your apps or software settings, but it could also be a hardware issue if something is disconnected.
Before trying any of these more complex solutions, try restarting your Roku first. Then, unplug it from power and wait a few seconds before powering it on again. It may sound like a silly answer, but it often works wonders.
Are you still having problems? Here are a few potential solutions:
Check your HDMI input at both ends if you have a set-top Roku. Your cables should be tightly connected to the TV and your streaming device. You may also want to check that you’re connected to the correct audio input. Finally, ensure the mute function is turned off, and try adjusting your TV volume.
You can use the Settings menu to adjust your audio input. Press the Home button on your remote and head to Settings, where you should find the Audio option. If you’re connected via HDMI, adjust your setting to Stereo and change your HDMI to PCM-Stereo.
You may notice that your audio and visual playback is out of sync. If this is the case, you may have to fiddle with your video refresh settings.
Roku’s companion app is an essential add-on for Android and iOS users, but it can be a source of some common problems. You can use the app as a remote control, and it’s the easiest way to add content to your streaming device. First, however, you must ensure that you get the connection settings just right. Like most problems, the root cause probably lies with your Wi-Fi connection, so here are some solutions.
Modern Wi-Fi routers often come with two different networks — a 2.4GHz option and a 5GHz one. You should ensure that both your phone and streaming device are connected to the same network, just in case. The two networks should talk to each other, but sometimes it helps to be extra careful.

The factory reset is the most extreme way to fix most Roku problems. As the name suggests, it returns your streaming device to its default settings. You’ll have to re-download and log into all of your apps all over again, but it should help fix common errors.
You can also use your Roku’s physical reset button to skip the menu steps. Some devices have large buttons you can press with a finger, though you’ll need a paperclip or something similar to press the pinhole reset button on the Roku Ultra.
Hopefully, we’ve helped you find a solution to your most common Roku problems. If none of the above tricks have worked, it might be time to replace your streaming device. Luckily, we have plenty of favorites to recommend, so look at our list of the best streaming devices around to see if you like any alternatives.
