Yamaha Modx 8 humidity problems

Synth Repair

I have a Yamaha Modx 8, and on three occasions, I have experienced issues with moisture getting between the keys.

On a couple of evenings last week when I played and the humidity was high, the tones were suddenly cut off, making it impossible to continue playing.

I’m wondering if there might be a fault in the circuit boards under the keys that is causing this issue?

I would appreciate your assistance in diagnosing the problem or advising on the next steps.

Best regards,

From past experience it will likely be an issue with another board other than the keybed. It might be an idea to talk to Yamaha about this since in my experience with them they are quite helpful.
