Hello everyone,
I own a roland D-50 synthesizer which some of the keys don't produce sound.
I tried to clean the strip rubber contacts with alcohol, but without success.
The funny thing is that the synthesizer itself it's in mint condition, and the bad keys follow a "pattern" ( I mean are the 3rd of each line as you can see in the picture)
I attach a picture which you can see the wrong keys with tape .
What could be the cause ?
The things are tried are:
1-clean contacts
2-try another rubber note in the place of the bad note.
3-Check diodes (which seems fine)
Thank you very much!
