Hi -
Glad to join the group. Earlier this week, my friend gave me an old
EX-800 that he really didn't know what to do with. It was pretty
dinged up and was missing the caps of two buttons (they still work) -
but I was still kinda excited. I took it home, hooked it up to my
MIDI controller, powered it on, and it worked pretty well. Part of
the display was really dirty - but from the inside.
Tonight I figured I'd open the case, blow some dust off the display
windows, and figure out if I can replace the caps to the two buttons
(the "1" and the "Parameter" button at the top. Also, the value up
button was sorta sticky, so I thought I'd clean it out and get it working.
...but then I opened the case. It looked like the EX-800 had been
standing on its side in someone's basement and sat in 8 inches of
putrid dirty water - the entire right half of the insides are coated
in a dirty gray/brown film. I'm kind of amazed the synth works -
these things seem to be built pretty solid, but the amount of damage
seems like a lot.
So - first, should I just leave the guts of the synth alone and not
try to clean off the water damage. Considering it works (to the best
of my knowledge) I wouldn't want to risk screwing something up by
attempting to clean it. But, if it's worth the risk (hey, it was free
and on the way to the junk heap), what's the best wat to clean off the
PCBs and circuitry inside?

Last, is there someplace/someone that might have replacement caps for
those two buttons? I know it's just cosmetic, but I sorta took this
on as a little hobby to restore this synth.

Thanks!
