|OT: LCD Repair Question|
Message #1 Posted by Maximilian Hohmann on 30 Mar 2008, 7:10 a.m.
since we had a thread on the Casio fx-190 (electronic ruler/scale) not long ago, I dare ask a question here that is related to this specific machine, but also applicable to HP calculators of course:
As you can see from this picture, my recently acquired fx-190 has a little problem in the LCD that generates the electronic scale:
For me, it is hard to tell wether the display itself is leaking, or some external fluid has penetrated between the display and the polarizer.
I am not really interested in calculators with LCDs (with some exceptions, like HP-71B and suchlikes and exotic calculators like this one here), so I never tried to repair a liquid crytal display.
My question would therefore be: Is it at all possible to repair defects like the one in the image above? I am a bit reluctant to take the calculator apart because it is in "like new" shape otherwise, and if the experts here tell me, that there is no chance of fixing it anyway, I will leave it as it is...
Spring Greetings, Max
NB: (Regarding the last fx-190 thread) I have the original manual (French/German) for this calculator in case there are questions left regarding the operating of the ruler or its (very exotic!) programming "language".
