Well, when you spill water on your Pro Keyboard, it won't work again. I've taken it apart, cleaned it, let it dry, the pencil trick, etc, all to no avail. About 95% of the keys work, but it is useless if 100% aren't operational. Now, after digging around inside this keyboard I know the paper-thin keypad membrane inside of it is the cause of the problem. Is there anywhere in the world I can find just a replacement membrane? I think the manufacturer is Mitsumi Electronics. I can hear everyone saying "uh, just buy a new keyboard." Well, why would I do that if I can fix it (I'm a fix it kind of guy) for a few bucks. That part can't be expensive. Any ideas?
