LCD fading, not only in the calcs Message #1 Posted by Alberto Fenini on 14 Mar 2011, 5:29 p.m. Dear All, while browsing the archives, I have found this thread : HP41C LCD/Display I'm attaching two pics of one of my Seiko Watches which has a similar problem, has anyone ever find a solution for increasing the contrast ?? take care and thanks in advance for any advice, Alberto

Re: LCD fading, not only in the calcs Message #3 Posted by TychoBrahe on 14 Mar 2011, 8:22 p.m., in response to message #1 by Alberto Fenini I had a Casio fx-4000P calculator that did a similar thing. It's from the late 1980s so I wasn't too surprised, but I was really fond of the calculator. About 10 years ago the display was starting to get dim, causing me to either up the contrast or buy new batteries ( which helped, for a few years ). But eventually nothing I would try would help. I've always wondered if it could be a capacitor that dried out or at least something that I could fix.
