I had a simple system where my mediocre tv was needing my mediocre (Sony STR770) receiver to be on (due to weak audio on tv)to watch TV. Also had simple rca outs from tv to secondary input at receiver to listen to files on a USB inserted into the TV..\nBUT..\nNow I have e much better TV with much better audio (purchased for that reason) so I can save the hours of the Sonys life for just LOUD music (like it should be).\nTHE ISSUE Is that the new TV has no picture when the receiver is turned off AND the new TV has no RCA outs for other sound source.. IT DOES have fiber out though..\n\nOf course all I have to do is bypass the receiver and all is well but I want my cake and eat it too.. please ...\n(BTW) I tried to use the fiber to the Sony, but could not get that to work.. Thus the failed call to Sony. Manual did not solve the issue of port assignment. (clue?)\n\nIs there a way to have both options.. TV sound for normal watching and then turn the receiver on and have home theater..(kinda-I have the Klipsch Bi-Amped) when I want to have loud tv?\nAll the help I have found include the basic (insert HMDI wire here) and the jump to massive information on 4k streaming CODEC's -leaving a whole lot of ground in the middle.\n\nThanks for any and all ideas!
