I can't believe it's just me that's encountered this - a buzzing noise from under the keys on my Disklavier Mk 3 upright? It's driving me crazy!
I can temporarily deal with it by inserting a credit card between the keys - suggesting it is coming from one or two of the small circuit boards under the keys. But how to deal with it permanently? I have tried just tightening up the screws, but I don't want to overtighten them because I don't want to damage the boards
Thanks
Kevin
