keys not working properly

keys not working properly

I have a yamaha piagerro npv60. The B & C keys have problems with it. Here's the scenario: - both keys played together, respond to velocity. If you play fast trills or scale, if u hit one first, the next key, either B or C wont sound. You have to time it properly to work. If you hold down either B or C and then press the other... The latter won't sound. But take note, in combination with other notes all is fine. Same issue for the F and F#. This happens in all the B&C and F&F# on the keyboard. Please help! Thanks in advance!

"Hi,

Have you tried to reset the keyboard to its' factory default condition to see if this resolves the problem for you.

Starting with the power off:

While holding the rightmost white key on the keyboard (C7) along with the three rightmost black keys (F#6, G#6, and A#6), turn the power switch on. ""Clr"" will appear on the display.

NOTE: Do not turn off the power while Clr is showing on the display."

"For everyone else searching here are a few options.

One is to use canned air to blow between the keys. The other (try at your own risk) is to smack the back of the keyboard. Finally you can undo all screws on the back and carefully remove any dust or debris, this is much easier and safer after you undo the ribbon cables attaching the two halves. With those carefully disconnected you can shake the half with the keybed to try and loose any dust or debris under the keys.

This issue can be caused by deteriorating rubber pads under the keys or dirty contacts. One solution may be to clean the contacts for the keys using alcohol wipes or to replace the rubber pads."
