My Klipsch proM had the left? speaker channel go out. Speaker still plays when hooked to the other channel although it sounds scratchy even though the other one does not. All I have done so far is remove the unit from the case there is definitely a burnt smell. Checked both fuses they are good. I have not pulled any of the boards just looked as best I can for any thing showing signs of failure I don't see any thing obvious. The main part Amplifier? says internal fuse, I'm assuming if that had blow then I would get no sound. My question is how to proceed. Any ones thoughts would be welcome including any other sites that may have more technical knowledge of this item. Thanks.
