no sound out of ONKYO receiver

Hello all, great site i've used in the past for t.v. repair.   Anyway I have an ONKYO TX-866 receiver which someone happen to spill a beer on and now there is no sound out of any of the speaker out-puts A or B side.  I've taken the unit appart and found a 1/8 watt 3.9k resistor that was blown so I replaced and it blew again.  I've looked through already posted answers on this site and it sounds like either a pre-amp or output transistor or IC is fried.  Any help on this matter will be greatly appreciated.
