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!
this (unplug for 30 sec) used to work for me, but the problem became increasingly frequent, and now is unfixable. I have an ultra and a no-longer so smart samsung tv. Will try buying a new hdmi cable but not feeling hopeful that will fix.
