Vintage Synth Repair

HI,
I think 1989 is now vintage ! 
if any equipment hasn't been used for several years then it is
"possible" that the battery used to store the preset settings will
either need to be recharged or if its a Lithium type replaced.
the recommended life of some batteries is only about ten years it seems
.
depending on the circuit design of a synth it is possible for a faulty
battery to stop a synth from powering up .
so you might be lucky and find its just a backup battery ....

Woah... You serious? I didn't mention it, because I didn't think it 
important, but I checked the battery (lithium) and SOMEHOW it is 
still 100% alive... but isn't soldered in! You can just pull it right 
out. The problem is, it would be a pain to solder back in, because 
the circuitry is integrated into the board- inaccessable from either 
side. I could work at it a little, though... I didn't mention it 
because I figured the battery was just to save the user settings and 
wasn't necessary to start up, but maybe it needs to be in the circuit 
anyway (the ROM may use it??). Thanks a lot- if it works it might 
save me $$ and a trip out of town. -Dave
