Default NEED Schem. for Pioneer VSX-4900S

Hello there;

I was replacing the spkr relay in my Pioneer VSX-4900S and it worked
for a moment but the main board was not mounted yet and it moved
enough for one of the temp compensating transistors to touch ground
and it popped something. Now, the receiver in in protection and the
relay won't even fire.

I checked all the B+ and B- and they're all there. Check resistors,
diodes and transistors. Can't find anything bad so far.

I'm hoping some kind soul has a schematic for this model.
Thanks,

Spark
