HP41CX scary moments - the sage continues Message #4 Posted by Vieira, Luiz C. (Brazil) on 26 Apr 2003, 2:12 a.m., in response to message #3 by Mark
Hi, Mark;
some months ago I passed some scary moments with my halfnut HP41CX. After experiencing a bad-contact behavior, it got into a "snooze" condition like yours: a high-frequency pitch, frozen keyboard, meaningless display. I readonce that removing the time module may "cure", but tell me: how to remove a time module... from an HP41CX?
I opened the calculator and simply shorten two capacitors inside it. One of them - the bigger one - seems to be in parallel with batteries (DC line) and the other... well, the h...! I shorten both and closed the calculator again. It was enough to put fresh batteries and see the so expected [MEMORY LOST ], sometime you hae it, sometimes you live, isn't it true?
As you have already been successful, I'm glad anyway.
Best regards.
