I'm having some trouble getting my stuff set up. I just bought an Onkyo TX-SR606 receiver. I also have a Samsung LN40A650 TV. I have my DVD/CD player & my cable box hooked up to the receiver via HDMI & the HDMI out from the receiver going to the TV. All of that works fine. I am trying to run my Wii via component cable & my playstation 2 via composite cable through the receiver as well. I get audio, but no picture on the TV for the game systems. Any ideas what I may be doing wrong? I can take some pic's after work today if that would be helpful of how I have it hooked up. Thanks for any help.

So then the only output to the TV is the HDMI connection?

Most receivers don't do component/composite conversion. You'll have to connect both game systems directly to the TV...the video outputs at least. There would be no benefit in running these through the receiver...and possible signal degradation.

Precisely. Although, some high end units DO upconvert the signals. Then you have handshake issues, and other sorts of things. probably best to run those directly to the TV, or have them pass-through the receiver if it can do that.

Got it to work. Many thanks to Ultra999. As far as the signal being degraded it looks pretty good to me. My receiver is capable of upconverting so maybe that is why. Thanks everyone.
