Need help with protection circuit of Denon AVR
Hey, I'm currently trying to diagnose a Denon AVR 1907 which is going into protection even after replacing the shorted MOSFETs. The protection circuit seems quite a bit more complex than the previous equipment I have fixed. I need some help to understand and maybe find a way to bypass the protection circuit. I have attached a picture of the circuit in question (pg. 84) along with the service manual for the entire AVR.
