RE: HP41C problem...very disconcerted
Have you measured the keyboard matrix with a multimeter? I had a similar issue with a 42s. Problem was a tiny spek of carbon from one of the plastic sheets that separated and made continuous contact. Poking with a thin shim between the membranes didn't help so I had to disassemble everything.
