Right on! Thanks, that is a great starting point. After I posted this message, I read late into the night and followed all the links I could find. I will pop out that board and clean up all contacts, maybe even pop out the two ICs and clean their legs. The smaller IC must have been socketed when it was repaired and new battery socket installed. After looking at some other peoples damaged PCBs, and comparing mine, I have a pretty badly damaged one. I can see some jumpers in place, but I will have to pop the whole board out and to some continuity testing to make sure the copper traces are working. Worst case is I get a hold of a new PCB and salvage as many of my old parts as I can and make up a new board.
Thanks Tony.

I bought it off a guy who restored it and I have opened it up to have a look and yah, like every other poly, it has past leak issues, which have been "rectified" so that it has been working fine for the last year.

Each time I turn it off and back on, it reverts to the same simple program. (I just measured the battery voltage and it is 3.17v) Also, when I choose any other patch OR bank, it switches to a sweeping filter sound program, and at that point no matter which program OR bank button I choose, there is no change in sound.

I am looking for a place to start trouble shooting. I am assuming it has to do with the 367 board, as I am noticing there is lots of chatter here about this board. I even noticed something in the "database" area, where it looks as if someone is doing a run of PCBs for the 367 (I just can't seem to find info about the detials)
