Default Amp question???

I have a Treo ssx400.1 and it will power on, not go into protect but has very very minimal output, only way you can tell its even working is when i have my hand on the cone... It also makes a popping noise through the subwoofer when you first turn it on. I have taken it apart before but nothing looks bad at all... so I am stumped, just wondering what might be wrong or where to look, very handy at soldering so if i can pinpoint the damaged component and source a new one i would like to try to fix it, since it wouldnt be worth my time or money to send it out to get fixed.

Not really, will be measuring voltage all over. I may need different one later.

Looking at some of the traces by the power input it looks as if it's been worked on before.
