Does the TV actually power off or is it just the screen that turns black because of no input? If the latter are there options in the receiver setup menu to configure an input (we'll call it input 1) to be video from source A and audio from source B? I did something similar a few years back - cable TV on display (no audio) while playing music.
Sorry, I wrote the wrong thing as it actually just goes to a black main screen and with a blue dialog box that says "searching for signals" and sometimes it says "weak or no signal".
I have previously used Optical out going to a receiver and HDMI out to the TV but that was on a receiver that did not have HDMI input. I do not see the benefit of not using HDMI since I have it on this unit.
I have looked at the manual and cannot find anywhere that it shows how to get the proper settings. I have tried all the ones I can find.
The TV is a Samsung FP-T5884.
Thanks!!
