Flooded SB-104 Battery compartment

I flooded the battery compartment on my SB-104 and am getting the flood signal and no flash. Any hope for reasonable repair? I flushed it with clean water and dried it with rice, but no luck so far. Had a new set of o-rings and stupidly put off changing them.

Thanks to Bob Warkentin at Southern Nikonos Repair, it's all fixed. He graciously sent me instructions on removing the top cover and drying out the leak sensor, which seemed to be the only issue, and now the strobe functions normally. Removed the hardened old o-rings and installed a fresh set and hopefully the problem won't be repeated.
