There was a update today to the Roku 4K software (9.3.0 build 4170). It has caused my Roku to flash static screen and make to normal non stop. TV is a Vizio M series. Anyone else seen this or known if it’s a known problem? Roku has been connnected to this TV for 6 months now with the same HDMI cables with zero issue.
Yes, I’m having the same problem. i’ve tried disconnecting power sources and different HDMI cables. Nothing works. I was so frustrated that I tried using the old XD I retired some time ago; but it didn’t work.
I saw this one one of mine. For some reason just pulling power and re-connecting doesn't help but when I pull the power supply from the wall outlet and reconnect it goes away for a few days. Welcome to Roku. Real poorly engineered junk from China
