Roku express 4k, turns “on” but tv screen black

I have Roku express 4k and have had it for about 8 months. Tried to turn it on and screen was black on my tv.

  • I have unplugged everything including the tv and wifi from power to check if that was issue
  • i have replaced batteries in remote
  • when I turn it on after unplugging things, it shows me “Roku” load screen and then goes black
  • light on the device has been purple this whole time and has not changed

please help, I am sick and just want to watch tv

Re: Roku express 4k, turns “on” but tv screen black

Hello @Swhittemore

Welcome to the Roku Community!

Could you tell us how are you powering your Roku device? Is it connected to the USB port of the TV or to a wall outlet? In some cases, the USB power provided by the TV is not sufficient to power the device. Even though your Roku device may appear to be working, running with insufficient power can lead to instability, crashing, and other unpredictable behavior.

Using the included power cord and power adapter, we suggest plugging your Roku into a working power outlet in the wall. Powering it through a power outlet in the wall has the additional advantage that your Roku player will not need to power up every time you turn on your TV.

Let us know if there's any difference after.
