Default Harmon/Kardon AVR35

I have a harmon/kardon AVR35 and I am looking for the schematic or service manual for it. I recently picked up this amp from a friend who said it didn't work.

The amp seems to work properly in stereo mode but when any of the surround sound modes all the speakers go silent. The same thing happens with analog and digital inputs, stereo mode works. I have checked through the manual and reset the cpu but to no avail.

I opened up the amp and checked the bias on all the channels, they are all biased the same and seem to be operational. I believe the problem is with the input stages of the amp, maybe the surround processor.. any ideas?

Service manual would be helpful, thanks,
btw I'm an EE so I can handle technical terms

Default Hello Nitryce

You can find Harmann Kardon schematics of the models:

AVR 15

in "www.shematicsforfree.com " than go to "audio related schematics" than go to "products" and finally "receivers"

I wich those ones can be helpfull someway as a reference for you.

Good Luck!

Sorry, Brazil only to be sold... top secret ultimate schematic, not to share...encapsulated VAS:
