I have a Directv RCA 450 hooked up with an Onkyo reciever,Toshiba VCR/DCD and TV. I have everything running through the receiver. The problem is that just recently I have started getting interference lines through the tv after turning on the receiver and/or the vcr. In other words, a clear directv picture until one of the other components are turned on. Picture then becomes full of horizontal lines and interfence sparklies. Any ideas??
