I have a 77" S95D that will sometimes show a black screen after using it and turning it off and back on. The issue occurs when turning it back on a few minutes later. Sometimes it stay black, but audio will play from the broadcast. I can turn it off using the remote but cannot get the screen to display anything but a black screen.
The only solution I have is to unplug it from the wall and let it reboot. Is this a problem with "Screen Optimization"?
Panel Care did not find any issues other than "auto-power off" which I want to keep on. Next, I will try resetting the TV to default settings after the TV stops being a black screen. I'll update in short time after completion.
Side note: I found "Panel Care" was grayed out if I was using common apps, like YouTubeTV. The panel care option was grayed out until I selected Samsung TV Plus as my source.
Make notes of the problems your finding. It seems like a component connected to the screen is shutting off the screen when the TV gets warm or hot. Whether it's the screen or a component linked to the screen needs a TV repairman to figure it out. In the days of the tube TV's one could pull out the tube's and test them at the supermarket.
