Please Help - "F" Note not playing

Post by PandaSkyDog » Fri Apr 10, 2020 3:24 am

Hello, I just got in very good state a DX7IID.
The issue is that one NOTE is not playing. It is the F. In any key... Can try F1, F2, F3, F4, and no sound.
I tried to reseat - the EDIT 16+32. Tried to recall from the ROM cartridge. Unluck.
Does anyone has any suggestion - more a guide - as it would be my 1st time playing with a DX7IID.
Thank you! :( :(

A few ideas: Reseat the 34pin keyboard cable and verify continuity of all pins. Possibly bad IC1 (74x138 demultipliexer) on DM board, can verify with scope or logic probe. Or other issue with keybed switch matrix.

Assuming the keybed is made similar to other keybeds, you might experience a bad contact on that key.
Might requiring cleaning.
