If your a fan of the blog, you know we love the Roku devices for their ability to install a “smart brain” into your home theater with minimal fuss. But like all devices, the various models of Roku streaming devices (and Roku TVs) can also fail in some strange ways. One issue many users have (especialy when they first plug their unit in) is a “low power” error.
To fix a Roku low power error, start by plugging the USB cable into a different port, or replacing the wall outlet adapter. Next, try a restart, and then update the Roku’s software. Try resetting the Roku device after that, and then consider contact Roku support.
We’ll look at these fixes in more detail in the next section, as well as a few more quick things you can try. Then, we’ll look at what causes the problem in more detail and a few more advanced troubleshooting tactics. By the end of this article, you’ll be back to streaming, so let’s get started!
Identifying Roku Low Power Indicators
First, let’s talk about what this looks like literally. For most Roku devices, you’ll receive a formal error message like pictures above, but for some of the bigger Roku boxes the LED on the unit can be used to diagnose this issue as well.
The Formal Low-Power Error Message
Typically, Roku devices may also display a formal low-power error message on your TV screen like shown above. This is the easiest way to know if this is your issue, and is probably why you ended up on this page! Just in case you have a more advanced Roku model, though, glance through our notes on the red LED below too.
LED Indicators (Red Light)
If the LED light on your Roku device is flashing red, this typically indicates that the device is not receiving enough power to function properly. In this case, you may not receive the low-power issue formerly, but if you suspect this is the problem, you’re int he right place. Now, let’s talk about fixing it.
5 Ways To Fix The Roku Low Power Error
If you’re experiencing the Roku low power error, there are a few steps you can take to get your device up and running again. Here are five ways to fix the issue, and below, we’ll talk about each more in detail before turning to more advanced tactics.
| Troubleshooting Tactic | How to Implement |
|---|---|
| Check the power supply and cables | Ensure the power source is consistent and reliable. For smaller sticks, swap their USB cable to another port on the TV, or use a wall brick. For larger units, replace the power adapter. Then check the power cable for any damage or signs of wear and tear and replace if needed. |
| Restart the Roku | You’ve probably already tried this – but go ahead and power-cycle everythign to clear one-off glitches. |
| Update Roku’s software | Navigate through Roku’s settings to find software update options. Regular updates can solve many power-related problems. |
| Factory Reset the Roku | Navigate to Settings > System > Advanced system settings > Factory reset. Follow the on-screen prompts to move through the process. |
| Contact Roku Support | If none of the above have worked, it’s time to contact Roku support to try and get more help. |
Checking USB Ports and Cables
Pro Tip: Most Roku low power issues are caused by the cable not being connected to a power source (USB port or adapter) that can support the device.
The first thing to check is your USB cable and port. Make sure the cable is connected properly and that the port is not damaged. If you’re using a USB port on your TV, try a different port or use a wall adapter instead. Not all USB ports on your TV can supply enough power
This can often provide the additional power needed to run your Roku device smoothly. If you need a replacement power adapter, consider purchasing an official Roku replacement adapter or an equivalent that’s rated for Roku use to ensure compatibility. This option, for instance (on Amazon) is rated for use with the Roku Express (also on Amazon).
Restarting Your Roku Device
Sometimes, a simple restart can fix the low power error. To restart your Roku device, go to Settings > System > System restart. Alternatively, you can unplug the device from the power source and plug it back in after a few seconds.
Software and System Updates
Make sure your Roku device is running the latest software and system updates. To check for updates, go to Settings > System > System update. If an update is available, follow the on-screen instructions to install it.
The Nuclear Option: Factory Reset The Roku
If none of the above solutions work, you can try a factory reset. This will erase all settings and data on your Roku device, so make sure to back up any important data before proceeding.
To factory reset your Roku, go to Settings > System > Advanced system settings > Factory reset. Follow the on-screen instructions to complete the reset.
And note that the Reset will give you a little more work: you’ll need to set up the device again, so, check out out other articles on if your Roku’s sound isn’t working, and connecting your Roku back to WiFi if you need them during this process.
Contacting Roku Support
If none of the above solutions work, it may be time to contact Roku support for further assistance. They can help diagnose any hardware or software issues that may be causing the low power error. If your device is within warranty, it may need to be replaced.
What Causes A Roku Low Power Error?
The low power error occurs when the Roku device is not receiving enough power to function properly. This can happen when the device is powered by connecting it to the USB port of the TV, which is not always able to provide enough power.
The low power error can also be caused by a faulty power cable or a damaged device. In such cases, it may be necessary to replace the cable or the device itself.
Preventing Roku Low Power Issues
Roku low power issues can be frustrating, but there are several measures you can take to prevent them from recurring. Here are some tips to help you avoid power problems with your Roku device.
Clearing the Roku’s Cache
One way to prevent low power issues is to clear the cache on your Roku device. Over time, the cache can become cluttered with unnecessary data, which can slow down your device and cause it to use more power than necessary.
To clear the cache, go to Settings > System > Advanced system settings > Storage > Clear cache. This will free up space on your device and help it run more efficiently.
Using the Right Adapter and Cable
Another way to prevent low power issues is to use the right adapter and cable. Make sure you are using the official Roku adapter and cable, as using a third-party adapter or cable can cause power problems.
Additionally, if you need to use an extension cable, make sure it is a high-quality cable that can handle the power requirements of your Roku device. If you need replacements, purchase Roku-branded products to ensure the right quality and power-management abilities, or trusted devices that you’ve confirmed are rated for this use, like the adapter linked above (and here, on Amazon).
Low Power, High Spirits: Wrapping Up Your Roku Low Power Issues
In conclusion, the Roku low power issue is a common problem that can be easily fixed by following a few simple steps. With Roku continuously restarting, it’s one of the common issues. The most common cause of this issue is using the USB port on the TV to power the Roku device.
The solution is to use the Roku power cord/adapter instead. If this does not work, then resetting the Roku device or changing the USB cable can also help. With these tactics in hand, you can get your unit working again and get back to enjoying your Home Theater in no time!
