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!

All of a sudden one ear stopped receiving sound. Did all the normal things like power on and off, disconnect and reconnect. Tired another pair of Bluetooth headset and it also is the same. Not sure what to check next. Any suggestions?
