Question about Denon AVR-2105 Receiver
Hi, I have the above mentioned amp, and I'm experiencing a couple of
strange problems. I have a 5 speaker arrangement, and when I set the
unit for 5/7 channel stereo, the right rear speaker works, but the left
front does not. When I set it to "virtual", the left front speaker
works, but not the right rear. Right front and center work in both
modes (left rear does not work because of a severed cable - not part of
It may sound silly, but can you check all your speaker cables again and confirm whether they are connected to the right connections. please check all cables as also the severed one and please repair it also.
Now please go to the system-set-up and do an auto setup and set up your speakers. Listen to the test tones and confirm that they are coming out of the correct speaker.
Once these are set, then if still there is mismatch of sounds, then we could further trouble shoot.

Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.
