Hello,
I've got an old Casio CDP-100 that's been acting up. One block of eight keys has been only working intermittently for awhile. However, after I accidentally left the piano turned on overnight, they stopped working altogether. I took it apart and found a weird quirk. Each key is connected to two diodes and if I touch them whilst pushing the affected keys, suddenly they all start working again for a short time. I'm guessing there's some sort of grounding issue, but I have no clue how to find and fix it. Any ideas?
Cheers,
Morgan
