[ICOM] Water damage to PW-1, now inop

Due to a burst water pipe, water poured into my PW-1 while it was operating! 
for a few brief moments (less than a minute) yesterday. I immediately 
removed the cover, dried the components that had gotten wet, and blew a fan 
into the amp for 8 hours to dry any remaining water.

Upon turning on the amp today, all visual indicators seem to be working 
properly - all the normal indicator lamps work, bandswitching works, tuner 
functions, ACC1 connection tracks the band that my 756 is switched to, and 
the fan starts. Everything looks normal UNTIL I switch to transmit mode. 
Then the amp/protect lamps switches to red and the band LED begins blinking. 
This failure occurs on every band, regardless whether the tuner is engaged, 
and into a dummy load (perfect SWR).

Any suggestions as to where I should look? Or is it time to pack it into a 
large box and ship it to Icom?
