I have to write you need to call Samsung to ask for help performing what resets are possible as well as help with settings.
I was moving my antenna on my TV from one side to the other and my TV went out. It was just flashing. I finally got the power line back in good and it came back on. The screen is so dark now. I called Samsung they walked me through the setting and then suggested I send it off to be fixed. Has anyone found a solution for this without sending it off. This is me Netflix Mt amazon prime and Hulu. Don't have the money to repair or replace for real.
