I think you'll have to check continuity between all of the components on the defective channel for that circuit. It goes from there to the larger caps on the right side of the board. Drive signal into only the channel with no bass to find which terminal (3 or 4) is the channel you need to follow).
If I drive a signal into the right channel which is the working channel I have audio on pin 3 of the input board.
If I drive a signal into the left channel which is defective I have no audio on pin 4 of the input board.
So the problem must be on the driver board?
The left channel produces audio when a speaker is hooked up. If I have audio on the channel why dont I have it on pin 4 of the input board?
