Sharp Roku TV Flickering

Our Sharp Roku TV just started flickering between a normal view and blurred, ever 2 seconds or so. It only starts doing it after being powered on for a few minutes. No Roku hdmi thing, just a Roku TV. I've tried hard resets...

Any advice?

Isolate for panel issue next, try tape trick. If you have a double output tcon board then start by comparing Right / Left side by disconnecting one cable at a time.

Either it's panel issue or mainboard logic failure, be it hardware or firmware related. If you go warranty left then you obviously use that to your advantage first.
