I have a problem with the contrast on my CFX-9850GB Plus WE.
Sometimes when i'm using the calc, the contrast (and color settings) suddenly adjusts by itself and gets very bright. This is pretty anoying because i have to stop working/programming and go to the menu to re-adjust the contrast everytime it happens (And it can happen anytime). I have no idea of why this happens and what i should do with it . Any ideas on how to solve it or what it might be caused by?

perhaps you are hitting Shift' /> and [<] or [>], that will change the contrast, if thats not the problem then its at least an easy way to correct the contrast once its been messed up.

No i don't think it can be that, because it usually changes very suddenly and often right after i have executed an operation. Anyway thanks for the usefull tip

You sure this works with color calculators?
I guess this works only with FX since it is monochrome.
Anyway, as for the color contrast, I had a CFX-9950GB Plus for some time, and on every light condition I had to change either the contrast or my angle of looking, and it was hell for me.
Indoors requires a certain setting to see all the difference between the colors, then outdoors requires another setting.

But, when I used the 9970G (the one that has simple CAS), it was excellent, it looked as clean and clear as the FX.
And I don't know which screen did CASIO use for the new WE.

So, what I'm saying, it's probably the angle you're looking with to the calculator, and not the calculator itself.

the problem is the batteries, change them and this should stop.

I don't think it could be the angle of looking, because the display is good to wiew from almost any angle. The display is covered with some kind of plastic, not glass as it were used on the older models. And when i press INIT (F1) in color menu, everything turns back to normal again. I have aleready tried to change the main batteries, but that didn't work either !

Did you reset the calc?

[Volcano]

Yeah, i have reseted the calc many times, but it doesn't work

[Brazzucko]

Try do make a reset at the ?hidden? menu one friend whit the same problem do that and the problem is over?.

[Volcano]

I've tried even that with no result. Maby it could be a hardware error . I suppose i just have to live with it, its not that big deal.

You shouldn't live with it, from the sounds of it, it is a problem of hardware and a manufacturer defect. Write to casio and demand they fix it, because even with the FX and AFX's out, the CFX's aren't cheap. If you make enough of a scene about it and explain it, I'm sure they would be willing to fix it (although they will probably charge you shipping and handling).

Well his right, after all I have see the CFX 9850GB Plus at 125 Euros and the FX 1.0 at 130Euros??. For me it?s one robbery???
