Tom,

Stay from all the advice about using anything stronger than a pencil
eraser,.. Actually I'd stay away from that too.

My usual techneque is to use isopropyl alcohol to clean the PCB, many times
those PCB pads have a graphite like coating on the and the I.A. dosen't seem
harm that.... Clean the keys with it also... it's been my experiance that
it's the keys that go bad, I've had good luck cutting the keys from the
keypad I don't use and replacing the bad key with it...

Is there any way to repair those membrane keyboard switches with the
carbon-like button that makes contact on a PCB? Sometimes cleaning them
works but not always and now I'm in danger of getting MY remote
commandeered due to a faulty remote in somebody else's possession. It
seems that there is a deposit on the PCB that is also affected and the
button seems to be non-conductive anymore.
