Question about Denon AVR-900 Receiver
Hello: I have a Denon AVR-810 that was damaged about a week ago. I repaired the unit by replacing the fuses, resistors in the main amp section and a voltage regulator for the display section. I also replaced the main output power transistors. Now when I turn on the receiver everything is OK and I can listen to music at different volume levels through my headphones (no speaker connected). When I connect the main speakers the unit goes into PROTECTION mode when I turn up the volume. I isolated this problem to the main outputs only and it only comes on when speakers are connected. I checked the bias and it reads about 0.024 Volts (24mV). Is this bias setting correct? Why does this problem come out only when speaker loads are connected? cant turn on my avr 900 protect signs on how do i reset tht thx flea

It sounds like there is a problem with the differential circuit. The bias I am not sure about, as every unit is different. You should get the service manual to be sure or call Denon and see if they can give you an idea. Good Luck
