Replacing contact strips on Roland JV90

Hi there,

My vintage Roland JV90 synth is still going strong, except for three dead keys. The keys are mechanically ok, but there is just no sound coming from them. I suspect a problem in the contact strips. Is there anyone out there who can tell me how to replace these strips ? I do have replacement strips

Turn the keyboard upside down and take all the screws out. The case should separate and allow you to remove the keyboard assembly. After that either the keys need to be removed or the contact boards need to be removed to get to the rubber.
If this is confusing then send me your email and I’ll email you the service manual
