Roku 4K video is Not Working

If your Roku is not connecting to the TV and you are sure that your TV supports 4K, check if you are plugged into the correct HDMI port. Not all HDMI ports are HDCP 2.2 compliant, you should check the user manual to be sure which port is 4K compatible and that should work well.

Your Roku Device is Overheated

If you have multiple devices next to or on top of each other, you may experience overheating problems. If your device is very hot, unplug it immediately and also disconnect all cables.

Wait for a minimum of ten minutes before plugging it in again. Some of the Roku devices have an LED light on the front and if the bright red light is on, this means that it overheats.

If it is still hot, even after you have turned it off, or you see the red LED light on, repeat the process. If the problem persists, you may have a hardware problem and you should contact Roku directly.

Roku Not Working Due to Insufficient Power

You may have problems with your Roku because it does not receive enough power.  Sometimes your TV has several USB ports and you think it’s OK to plug in your Roku stick or Roku Express to absolutely any port.

The problem with the USB ports is that not all of them are capable of giving enough power and some of them were not even meant to provide any power at all.

Try connecting your USB cable to the adapter you have received with your Roku device. Plug it directly into the wall socket and this should also solve your problems.
