Re: HP-48SX display problem Message #2 Posted by Michael Fink on 10 Jan 2006, 11:55 a.m., in response to message #1 by Fabio Albonico
Ok, I am not suggesting the following as a repair method, but anyway, I got a similar problem with my SX fixed in a quite unexpected way.
Actually, my USA made 48-SX had the opposite symptom: a vertical line of pixels and most of the indicators were permanently on. After the problem persisted for half a year, I made up my mind and ebayed myself another SX, this unit made in Singapore. When I was just about to transfer my programs from the old SX to the new one, I was interrupted and put the two calculators side by side in a drawer.
Two days later, I was surprised that the display problem had magically disappeared, and my old SX has been working perfectly ever since. Despite my strictly rational upbringing, I cannot help wondering if the old SX started to realize that the situation was becoming serious for "him" and stopped acting up. Or maybe it was a little encouragement from a friend from overseas that got it working again. Other theories welcome :-)
