Hi All - first time posting here. Pulling my hair out trying to figure out whats going on with my receiver. I bought it 3 years ago as a refurb on Woot. For 2.5 years it was working great with my Front LCR speakers (no sub). Recently it started to act up with the electronics, wouldn't turn on without going into protection mode. Sometimes would take 48 hrs until I could even kick it into the Protection mode, because it didnt want to turn over (faint click, faint red light, almost like there wasnt enough juice to start it up). Well it's been powered on for weeks now, but the new issue is no sound coming from my L and R speakers, only the Center. It's not a speaker issue, as I've tried all three speakers in the Center terminal and they work. When running test tones in settings, I don't hear anything coming from L and R, only C. I tried replacing speaker wires, reset the banana plugs, I did a factory reset on the receiver. Is there a chance those two terminals are faulty? Is there anything I can try to confirm this? At this point I'd rather know if its beyond repair so I can just begin shopping for a new one, unless I can fix it myself. 3 years is too short with a receiver!
