Removing excess PCB s from an AVR to make it a stereo amplifier ?

[ketansethi1987]

I have AVR s which I used front left and right channels for audio 2.1 listening..how do I remove the excess PCB s , say for video processing etc...that are not needed, such that I get closer to a stereo amplifier sound?

Please do not attempt. You will end up with a dead AVR. I have dead AVRs even with all the boards present LOL!
A lot of things will need to be bypassed and I do not think it is possible. As audio is passed via the HDMI boards in most AVRs. Whenever there is no audio, most of the time the HDMI board is the culprit.
