Re: only the right channel working on the amplifier
First check on all your cabling, speakers and input sources for loose/defective cables. can you tell me what brand is your amp and model? does it employs digital source switch or mecahnical switches only.

I would prod and poke the channel with an insulated screwdriver this will cause buzz sounds. This should find the cause of the problem. Remember that the left hand channel is identical so you can compare the right with the left. For example if you get a weird buzz on the right when you touch it, but not on the left at the same point you might have found the faulty part.
Don't go near the power supply section as it's nothing to do with that the fault.
Check the bias resistors. They can burn out when power amp transistors fail. They will be very near to those two replacements. You can compare any parts using the right channel as a good. Readings and voltage measurements should be the same for both channels. Also the look of the parts. If a resistor is off-colour in the left, but not in the right you know something is up.
YOU ARE NOT RIGHT IT SHOULD GIVE AT LAEST A LOW VOLUME SOUND WITH A LOT OF DISTORSION AND A CRACKING NOISE IF DOES I GUESS THAT YOU HAD THIS AMP IN A PLACE WITH A LOT OF HUMIDITY AND YOU HAVEN'T WORK IT FOR SOME TIME IF I AM RIGHT PUT YOUR AMP IN THE SUN AND WORK IT FOR 10 MIN WITH A 5 MIN BREAK LET ME KNOW THE RESULTS
Go directly to the main amp, follow the leads from the speaker terminals. And you should find something on an heatsink. If there are two transistors see if they are running hotter than the other channel. If you see any damage to them (compare with good channel) replace both!
If all you see is a black box with pins coming out of it you need to replace that. They sometimes have the letters STK on them.
Replace both types with the letters and numbers of the same type. IE 2SC 1220 or STK 589.
disconnect the cabel of left channel from your amp disconnect the cabel of right channel and put it in place of left channel if the problem goen your problem is in left speaker itself (cabel or speaker).if the problem excit the problem will be in amplifier output stage
