No sound from left channel on power amp

I've got an Audiolab 8000P power amp in bi-amp mode. Just the other day, I noticed that I couldn't hear the "bass" from my left speaker. I ruled out that it was the speaker cuz I swapped them and same thing happened with the other. I checked the cables and source and ruled out that this problem was caused by any of them. So, this was the power amp I'm using for the low frequencies. I can power it up and one channel is fine. Any DIY suggestions other than bringing it in for repairs?

Thanks

I do not own that amp but my suggestion is to look at your fuses,almost all of my amp problems were due to a bad or blown fuse some uses a resistor.

maybe very minor,check the left channel fuses/resistor.

hope that is all,good luck.

Open the cover (or read your owner's manual) and look for fuses* in the powersupply. Lots of amps have them.

* I don't mean the main AC-power fuse.

There may also be rail fuses along each bank of transistors that could blow (Acurus amps are like that). Have you tried contacting the manufacturer (if the owner's manual provides no guidance)?
