I would suspect the display board, but if it were mine, I'd send it to fixthatcalc.com which has an excellent reputation for fixing these things. Hmmm... Now that I think about it, last time I heard, they did have quite a backlog, so turnaround time isn't the best. For anyone here who could offer more help, it will probably help to tell them if it's a coconut or a halfnut. (There never was a "fullnut," and it sure bugs me when people call it that!) Fortunately I've never had any trouble so far with my 41cx halfnut or 71B's.
