Pioneer SX-737 Problem

I recently got my SX-737 fixed for a fried output relay. After it was fixed it ran perfectly for weeks. A few days ago I had left my receiver on overnight (on accident, I always turn it off when not in use) and I came back and.. no sound. I turned off the receiver for awhile and then turned it back on. I got the "click" but then shortly after the right speaker (Pioneer HPM-60's) made a crackling noise and popped. I turned it off again and then turned it back on and received no audible "click". I turned it back off and waited about 20 minutes and turned it back on and I DID receive the click again however the same issue occurred shortly after. I re cut all of my wires and attached them to the B connectors instead of the A and... it worked perfectly fine. However about a day later while watching a video the right speaker started crackling and then... no sound. Same issue as stated above. I really only seem to hear the sound from the right speaker. I'm not sure what the issue is. If maybe it's an issue with the right speaker that could have fried something? Also of note I don't know if it's just coincidental or what but both times I had left my receiver on for long periods of time prior. Although of note I have used it for periods just as long prior. Any answers to this problem are greatly appreciated. Thank you :)

if your power amp has the 2sc1451's in it, they could cause this problem. However, I would rebuild the PS Board, the Protection Circuit and the Amp Board at a minimum if I was going to keep the unit.
