Malfunction of LCD segments on 41 display - Jean-Michel - 02-22-2007 Hi everybody,
some segments of the LCD display of my 41 doesn't light on when the calculator is just turned on, but a few minutes after, they operate correctly, with sometimes another malfunction during a few seconds. ((They flash slowly). Another thing : could anyone post here two pictures to show me the difference between tall keys (41) and the other keys ? (Or a link to a previous discussion on this subject).
Thanks.
Re: Malfunction of LCD segments on 41 display - Eric Smith - 02-22-2007 I would expect that to be caused by either a mechanical intermittent connection between the right display driver chip and the actual glass, which I'm guessing goes through an elastomeric connection, or (less likely) by a failure of the right driver chip. Unfortunately a failure of the interconnection between the main PCB and the display, while it would be much easier to fix, would not result in the described symptoms.
