DVD player not working properly
I have a DVD player, a VCR player, a TV set all hook into an RCA RT2250 Audio/Video receiver. Everything was working fine until 2 days ago. Now the DVD player gives me a great pix but no sound. The VCR,and TV are just fine and I have checked everything out, speaker connections, mute buttons, etc. and nothing seems to be wrong. I am thinking that some thing in the receiver got fried. Is it repairable?
