Screen blinking on and off

My Roku was working fine until one day when we turned it on, give it a minute or less, the screen would constantly blink on and off and doesn't stop. I've tired to unplug it, reboot it, reset it, but nothing seems to work. Please if anyone can help me that would be great, thank you!

Re: Screen blinking on and off

  1. What model Roku (number, not name)?
  2. What brand/model TV?
  3. Anything else in the HDMI string (AVR, sound bar)?
