Hi all,
Newbie to both this forum and electronics! I have a somewhat old Casio CDP-100 with 8 keys that went dead recently. All other keys are fine and speakers/power are working perfectly.
Schematics here: http://www.warningwillrobinson.com.au/manuals/Casio CDP100 service manual.pdf
Since my dead keys are F3-C4, it looks like from the circuit description on page 3 that the issue is the F14/S14 line. I opened up the keyboard and have been looking at the MAIN PCB M403-MDA1 (manual page 17) but not quite sure what I'm looking for. Any advice? Am I looking in the right place? Any obvious fixes here?
Attached front and back pictures of the MAIN PCB in case anyone can visually see any obvious damage.
Thank you!
