Trying to run TV sound through the receiver. have tried running signals from TV audio output out to the receiver, have tried running signals from DVR to receiver, DVD to receiver, etc. All of the above result in terrible sound. Loss of midrange and treble frequencies, and the sound is so low that I have to turn the volume way up on the receiver. I am afraid that I will blow out the speakers if I forget to turn the sound down before I select the CD audio source. Any ideas? The CD sound is great. Using RCA cables. Have switched to different RCA cables. No help.
I would guess that the switching chip is faulty inside the receiver. Since the CD works OK, the amplifier section and pre-amp section are good. What you are hearing with the others is crosstalk. This chip shouldn't be more than about $10-$15. Add in the local labor rate for the total repair cost. I think that the chip for your model is a TC9163.

You might want to ponder why you would need audio from a TV in the first place if it originates elsewhere like a Cable Box. The fewer hops and interconnects a given signal takes on the way from the source to your ears, the better (and cheaper, too, as optical or HDMI cable is expensive). You COULD skip the TV entirely. Many don't even HAVE audio (monitors, for example). The receiver only NEEDS a basic composite video output to the TV so you can use the TV for setup and control. You COULD run vanilla stereo audio to the TV from the Cable Box for watching Oprah.
I run all of my best DIGITAL audio directly from the sources to my VSX and the best DIGITAL video directly from the sources to the TV.
