From both the CD & BD player, see what that does when you connect directly to the TV.
If that works, then try another set of cables/check to see if anything's loose. If that's OK, do a factory reset of the receiver, then try setting it all up from scratch. Beyond that, you may need service.
I have a Pioneer A/V receiver, which I have used for about 2 years. It has worked well. Now it will not output signals from the Cd player, and the DVD/BR player. Both worked fine before. I ran both through the TV and both units are working.
Is this a receiver settings problem (I don't think I changed any settings), or is it a component failure inside the receiver?
This is a Pioneer VSX-9040TXH receiver(Canadian version of Elite VSX-21TX).
