Hiphonics Zxi 1008 amp has DC offset on outputs

Dear members, My name is Tom and I am from Wells, MN. I have the above mentioned car audio amplifier that I have been working on for the last two months but cannot figure out what is wrong with it. First it started with no out put to one of the two channels. After pulling all of the outputs on the bad channel it worked for a while then the protect light started to come on. I have pulled all of the mosfets, output and power transistors from the bad channel so that only one of the channels is operationally. Now it has a really high DC offset on the good channel that starts at .1mv and goes to about 3 v dc before the protect circuit kicks in and shuts down the power supply. This amp has got me really confused and to make matters worse I can't find a schematic for it anywhere. Any and all help with this would be greatly appreciated.

Thanks
Tom S.
