Just a shot in the dark: I had a 41 with that issue which turned out to have a bad connection to the LCD (and switch) board. Reflowing those connections fixed it.

It was a particularly annoying problem because just disassembling and reassembling the calculator would "fix" it for awhile, so every brainstorm I tried seemed to "work".

(Hopefully Randy will stop by and suggest a more scientific approach!)

Update: Some good suggestions from Geoff and Den in this thread
