Amp help

[Slobalt]

I have an eclipse 32440 premium I bought knowing it needed repair. Now to be honest I have almost no idea what anything is on the board but I want to learn. Nothing looks burnt or broken except the led light that would shine on the side of the amp is gone (for power on/off). So the problem, I can get sound out of all of the channels (4ch amp) but once I turn it up all but one channel shut off. So only one channel will continue to play at any real volume. Any help is appreciated.

This sounds like something a professional would have to troubleshoot and fix.

Any on this site or do you know of one I could contact?

All repair guys will tell you to send in the amp. Might be just a bad resistor or diode

hmm, my guess would be weak or failing MOSFET's but w/o physically checking the amp there is no way to tell..

Pics might help out here also of the internals to spot something unusual.Hard to say without any pics or being present for most repair techs.
