EV ZLX-12P Amp Repair

[systembounce]

Hey everyone, first post on this fantastic forum, hope I'm not breaking any rules!

I recently acquired an Electrovoice ZLX-12P monitor.  Someone had accidentally  plugged an amplified signal into the line input. I've done some basic diagnostics thus far.

Symptoms:
Powers on fine albeit with that sad smell of burnt circuitry.
Channel one gets no signal. Channel two gets intermittent signal that varies from no signal to clean but quiet to horribly distorted (seems to be linked to volume of incoming signal)

Both PCBs look fine to me, no blown up caps or scorch marks.

I have no idea where to start poking with my multi-meter. Contacted EV and they will not release the schematics

The only thing I could find was that there is some guy ( from Russia??? of course) on speakerplans dot com that seems to be providing the schematic to those who ask.... May be out dated but, if you haven't tried that already, maybe try to get them from him???

Then post them here and someone may be able to help more...

Including your location in your profile will be useful as well....

Good luck!
