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"?
