Re: 41CV keyboard problem Message #2 Posted by Erik Wahlin on 23 Apr 2000, 1:59 a.m., in response to message #1 by Kevin
What I have done that works, is find the small hole under the key on the internal circuit board, and squirt some contact cleaner into the hole. Then tap the key several times. Unfortunately, to get to the internal circuit board, you have to take the calculator apart. Be very careful because there is serious risk to damaging the CPU board contacts if the CPU board is removed. Some of the keys holes are located under this board.
