Question about Denon Audio Players & Recorders
First, be sure your speaker is good. Test both speakers one after the other on the channel that is working to actually confirm if it is not a speaker fault....
After that, cross check your speaker wires and make sure they are intact.
Now check your input wires make sure they are good. Also, check the speaker balance settings on the amp and make sure it is at the center.
Check your CD player connected to the amp, make sure it is set to Stereo and not Mono. Mono will make on one speaker work.
If non of the above seem to be the cause of the problem, then the problem has to be from the Output of the amp. Check the output fuse on the channel that is not working. If the fuse is intact, then it means you will have to change the output.
I hope the above makes sense to you. Let me know if you still need more assistance....

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.
Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; 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. Eure 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 and competent hands-on tech.
