have you tried looking at your phono leads,turn volume down until it is low enough that you can still hear the music playing,give the phono leads a turn to see if its a loose connection.if not,try the right channel phono in the left channel to see if this fixes your problem.also you could do the same with your speaker leads and see if that solves the issue.maybe a bad connection is the cause?.it may also help to try and move your cd player away from your amplifier.it could also have been overdriven (played too loud for too long) on the night of the party,only you will know if this was the case or not.
It could be a number of things. Try this test first though. Play some music and swing the balance control to the bad channel and turn up the volume all the way if needs be. If you hear any music breaking in the pre-amp is ok. If not it could be dead. Again if you hear faint music it's the power amp that's not working.
Next have a look inside. You should be able to identify the channels by following the wires from the speakers. Remember that stereo amps are just two mono amps joined. So the Right Channel will act as a guide to what the left should look like. Plus if you are any good with a volt meter provide the correct voltage indications. Any burnt/damaged parts on the left and not on the right is an indication of the fault area. If you have no output from the above test pay close attention to those parts on the heat-sink for the affected channel.
Ignore the power supply parts are anything that is on it's own, unless it's an IC with both channels going into it. As they can go faulty on one channel, but not the other sometimes.
If you can't find anything it might be an idea to replace the left output device(s).
First detirmine if it is only the turntable that is causing this problem, by connecting something else to another terminal. If that works fine it will be the cartridge preamp that is causing the problem. From what you describe it sounds like an IC that is playing up.
If the other device plays up as well as the turntable, I still suspect an IC, but this time in the main pre-amp. The reason I suspect an IC is that by the sound of things both channels are playing up and therefore it has to be somepart that has both channels going in and out of it- thus IC!
You should be able to online to the manufacturer of your products and download manuals. However, I will try to help.
Connect the sound output cables from your DVD player including, left/right(white/red) as well as the Coax output/input if your DVD and your Carver each have this feature for enhanced sound on certain DVDs, and connect to the matching DVD inputs on your Carver.
Then, connect your DVD video output either by use of your RGB(RED/GREEN/BLUE cables or an S Video cable to your the matching video inputs on your t.v.
On the back of your Carver, you will find outputs for left and right speakers, connect to the left and right speakers with proper wire. Make sure that the 2 conductor wire is connected with the same side(polarity) on all speakers for the best sound quality.
You will also find rear channel left and right outputs on your amp, connect those to your rear right and left speakers.
Connect the center channel speaker to the center channel speaker output on your amp.
If your Amp has a sub-woofer output and you have a subwoofer, make the connections on that as well.
Test all of the speakers with a feature that many amps have on the menu using your remote, simply called test. if all speakers are connected correctly you will be able to hear each one as they are individually tested by the amp. Hope this helps out.
In bridge mode, the left and right amplifiers are in essence connected together. Typically, the speaker connections are to the positive connectors for each channel for this mode. WIth the speakers still connected, you essentially shorted the outputs to ground and smoked the output section. The unit will detect this now and not turn on the output section. Your unit is in what is usually called "protect" mode. This unit will require repair. Expect to have the output transistors replaced at the very least. I would estimate around $16-$40 for parts.
volume levels on all channels varies depending on what dsp mode you are using. to be able to determine the level you desire, just chnge the level setting of those channels. either you do it by remote control or the front panel of the amp. try setting the dsp mode on disco and you should hear higher vol levels on all channels. Do not expect as well all channels to produce same vol levels as your effects speakers may not be able handle higher power levels.
check volume balance between right and left-then change inter connection between sound source and amplifier with new cabel(i prefer gold plated type connectors)(see radio shack). after that if the problem excit your fault in output transistors or output stereo ic depend on circuit design.
