If your Roku is overheating, then this may cause audio drop out or possibly sync issues before the Roku shuts down.
It is considered normal for your device to get warm during use, but in some cases, it gets warmer than it should. Two common ways to tell is if the white light on the front turns solid red (blinking red is insufficient power) or you may get a message on the screen indicating that “Your device is overheating”. More subtly we have heard that Roku devices may have an issue with the audio dropping out completely or the audio may get out of sync with the video.
First, let’s get it cooled down. Be careful as the device could be very hot and could burn you in some extreme cases. Carefully unplug the power from the device. Give it at least 10 minutes to cool off on its own, and it should be at about room temperature before proceeding.
Next look for a cooler location for the Roku.
- Common sources of overheating to avoid are: inside a closed cabinet/space, on top of other electronics that may heat up (amplifiers, audio/video receivers, cable/satellite boxes, routers, cable/DSL modems), and direct sunlight.
- The backs of some TVs can also get hot or have limited airflow, which can be addressed with an HDMI extender or longer HDMI cable (depending on your device’s connection), and sometimes just by using a different HDMI port on the TV.
- If you are using a power supply other than the one provided with your Roku, it may also contribute to the device overheating by providing the wrong voltage or amperage. Device manufacturers supply these to make sure the device gets the correct power. The wrong power supply could actually end up harming your device.
Next retry powering the device and see if it performs better after cooling down.
If it happens again, before unplugging it then we need to get the temperature from the device. Roku has a secret screen that can be accessed to check the temperature of the device. To get to it, from the home screen press: Home (5 times), then Fast Forward, then Play, then Rewind, then Play, and then Fast Forward. The temperature will be displayed toward the top of the screen in Celsius. We don't know what Roku considers to be too hot. After writing that down, please unplug the device and repeat the above steps one more time.
If the problem persists, then please go to Roku.com and under Setup & Troubleshooting, there is additional information from Roku.
