I have a Sharpe Roku TV (not a Roku device hooked up to a tv). And I turned it off before going into work today. Came back turned it back on and the screen was really dark, normally it’s bright, and the screen was flickering every three seconds. I tried everything
changing the brightness to normal
unplugging it and plugging it back in
This tv hasn’t been really used until this year. Before that it’s been sitting in a guest room untouched. I don’t know what I did.
