I have a Casio e-100 that's about four years old and I'm really happy with, but the screen backlight seems to have gone crazy. Today while I was playing a MAME ROM, the backlight started jumping in and out. I quit MAME and so then when I used pressed the screen with the stylus it would jump to super bright, and then back. Now whenever I turn it on I can see the backlight flickering- I reset the unit and it still happened. If this can be fixed without taking apart the unit I'ld be really happy.
Any help is great'ly appreciated.

There's not really a "click and fix" for this one. It appears the LCD has gone bad or the backlight has burnt out. If you like DIY projects you need to replace the LCD or the backlight, which can very tricky.
I would reccommend going to a local computer repair shop to get it fixed. Do not use a "big box" retail store they think everything is a virus, don't fix the problem, charge an arm an leg for doing nothing.
It may be better to buy a whole new computer, since this usually costs over $100 or more. Good luck with your screen.
The backlight inverter board may have gone out, or the power supply for the inverter may have gone out. If it is two years old, you should look at the power supply first for bad capacitors. http://en.wikipedia.org/wiki/Capacitor_plague
Please post back what you find. What is themodel number anyway?
Well, there is good news and bad news....
The good news is that your digitizer is working okay...the bad news is that you lcd isn't.
This is due to three possibilities...
1. The video controller on the motherboard is bad...unlikely
2. The ribbon cables or connectors that attaches the lcd to the motherboard is bad...possible but unlikely
3. The lcd itself is shot or damaged...seen it more than once.
The only way to really tell is to find someone else with another unit and just start swapping out pieces until you can rule out the trouble.
Or in the interim, it is possible that the cable just jarred loose a little or has become dirty, preventing full contact. Simply disassemble the thing, clean the contacts, and put it back together...not hard to do, but not for the feint of heart either.
Good luck, hope you get it fixed.
p.s. Don't be afraid to take it apart...what can you loose, just be very careful to document each step if you haven't done it before. I've done it a couple of dozen times on various Casio E-1XX machines and never had any problems yet....
