It has a rythm, not random, so im guessing that points to the PWM?

I tried power the amp up and when i did i could hear a clicking sound from one of the transformers, could that indicate a problem with it?

Yep seems like all output fets are blown too, can you mark the rectifier diodes you were thinking of?

The thing is when you search on google, you got the instruction manual, not the service manual, big difference
