I'm a technician myself and to fix the problems I'm now looking for the service manual (not the owner's manual) with the technical schemes of the receiver. Can someone help me please??

Usually a bad output IC - I believe yours used them. Fairly expensive from Pioneer, and there are usually no subs, at least no cheaper ones. They got wise and quit printing the STK number as part of the lot number on the backs of the chips. Try to measure a DC offset at any one channel. That would point you to the bad chip. You can measure at the white emitter resistor in front of each one. There's probably 5 or 6 resistors total.
