The dead keys are not in a particular place but all along the keyboard, like there are two here and then a couple that work and then more dead ones then more good ones. Is there some way to clean the contacts on the keys, or is it possible there are electronic components failing. Or is it a sign that it is not fixable, in which case he will just sell it off for parts. He owns a KN3000 and some of the keys do not work, Is this a problem that is a common fault with this model and if so is it fixable.
