AVR-1909 no audio output
I was hoping someone might help me find a troubleshooting breadcrumb to follow. I don’t want to have to take it entirely apart and test every capacitor, resistor, fuse, and transistor to sort the issue out.
I am looking over a Denon AVR-1909 receiver. The unit will output video but no audio.
Steps I have tried:
Re-seating a headphone jack. I see display note the insertion and removal of the headphones and I can hear the relays clicking over as I insert and remove the jack.
No audio outputs to speakers or headphones for any input selection, including the AM/FM tuner.
Protection history is empty
Resetting the microprocessor did not change the symptoms.
I inspected the inside of the unit for any visible damage, bad solder, blown caps, etc and found none.
Thanks in advance!
