Update replaced two op amps still not working 😔 any ideas? -
I've measured the forward voltage drop of all 13 of the op amps most of them seem too high but the zone 2 ones seem okay which would explain why zone 2 works also I've measured the muting transistors all of them seem too high even zone 2. Page 24 shows 7 of the op amps (njm8080g) and the muting transistors (inc2002ac1) and page 27 shows the other 6 op amps.
Any idea what could've caused this? If I replace just the op amps would it work?
U4211: blank
U4212: different amp but .6
U4210: .6 main l r so idk
U4209: .6...Leave a comment:

Or could it be operational amplifiers?Leave a comment:

Update: When I plug headphones in and turn the sound all the way up I get very faint sound through them only on the phono input though which has an extra pre amplifier circuit. Now I’m looking into it being some sort of bad capacitor on a pre amplification circuit. Can anyone help isolate. page 24 on the service manual shows it I think but I don’t really know what I’m looking at....Leave a comment:

I’ve factory reset. For now I’m just trying to pass stereo audio through so I don’t think the zones matter other than me being able to get audio through zone 2...Leave a comment:

Also does anyone know how to get access to the firmware the service manual says to download it from the on line parts list sdi but it requires login. In particular I want the audio pld 5M570ZF256C5N firmware [TABLE="cellpadding: 0, cellspacing: 0"]

Denon AVR-X3600H No sound even to pre outs in direct analog mode. Help please!
Hi, I have a Denon AVR-X3600H I'm trying to repair. I have no electronics repair experience but I have a multimeter, service manual and a will to fix it ([url]https://device.report/m/d5de8c00e6176bdc778ad456784d56fce173a068835643bf6b7324f63147aba9.pdf[/url])
Everything seems to work except for no sound even through the pre outs. However I will get sound using Zone 2 pre outs.
Only digital symptom I can tell is it will soft lock when in the Speakers/Test Tone menu and be unable to adjust +/- db during the test tone.
I've followed the trouble shooting guide,... -
