I'm currently building/assembling a pair of Icepower 125asx2's the cases are aluminium and my speaker binding posts weren't isolated, I didn't realise when testing and damaged the amp as the speakers were all shorted out together. I have now isolated the speaker binding posts but now channel one has horrible noise coming through, hissing popping buzzing, the amp is basically unusable. Any idea what damage I've done and if it's fixable? Thanks
Inspect PCB for visible burns, smell. Check switching transistors TR360/TR362 on the top and TR361/TR363 on the bottom of the PCB. It is what I can say now without schematics, it could be faulty diodes too. In the next step I would look at the DC power delivery, blown SMD fuses, etc.
thank you!, there's nothing obvious burning or smelling.
Posting some pics if anyone can spot something.

An externally hosted image should be here but it was not working when we last tested it.

thanks thegoldenear
Do you know how they were killed? So you wouldn't recommend paying $50AUD to check if they can be repaired at my local electronic repair guy?

Hello,
i have 125asx2 and i find burns transistor TR360/TR362, where is the problem? if you have a schematics you would send it to me by mail please?
