My Cassiopeia has a grayed out section in the upper quarter of the screen. Does anyone else have this problem? It blinks off and on at times. I had it repaired by Casio once while it was in warrenty but now if I want it repaired it will cost me over $200. Thanks for any advice you can give me on how I can fix this problem myself.

Re: Casiopeia E115 has dark section of screen?
This has been apbroblem with Casio E-100 to E-115.
The LCD display is connected to the main PCB via a flexible circuit which also carries the display driver ICs. This circuit presses against some components on the PCB near the power button. Over a period of time with generated heat this circuit gets deformed & shifts the phase for the upper 1/3 of the display.
So you will notice if you reset the device this very portion is brightly lit in stead of being completely black like the rest of the display.
There is not much you can do except change the Display unit consisiting of the LCD, Digitizer & the backlighting fluorescent lamp. It is not a very difficult job if you are not 10 thumb variety.
You could try heating this flex with hot air gun & flattening it again. However you might be taking a big chance withthe display.
You could try Pacific parts / casiosalesandservice for replacement.
There were two version used in your device. So compatibility could be an issue.
Contact mre directly if you need further assistance.

You hit the problem on the head. If you can still see an image, albeit extremely faint, and the Casio is still working, i.e. playing an mp3 file or whatever, then you definitely have a problem with the backlight. More times than not, this is either a daughterboard problem or a connection problem (rarely have I seen an actual bulb failure though it can happen). One of the more common causes is the tiny ribbon cable connector on the daughterboard. You might try to disassemble it, clean the contacts of the ribbon and reassemble the device.
I've also heard of people squeezing in the side of the case to temporarily effect repairs...this is normally more ominous.
I believe if you are hardy with this sort of thing you can order a new touch pad from Global Products or www.pacparts.com. The e-115 , e125 and others all the same. Mine is coming from Global now item # 10003145 @ $28.00 I believe. I will know more when mine arrives. The case is not to hard to crack open just be careful.
Once the case is open and motherboard freed turn the mb. over from case. The touch pad removes very easily one ribbon connector and one tape. Tear down pictures @ www.hi-pda.com/usercomment/001215/1.jpg. Be careful to have static band or discharge don't touch except edges and plastic of compact flash. It will take a little work but it is the cheap way.
There are 2 things you have to check for.
The touch screen was changed in the middle of production run. The flexible connector & the corresponding socket on the main board were inverted. In other words the exposed track side was moved from upper to lower side. The older type of touch scrteen is no longer available. Casio made the socket available to their service centre to change in on the main board to suit the newer type of touch screen.
If this is the case you will have to get the newer type touch screen to suit the E-115.
The second aspect is that there are 4 self adhesive spacer tapes (approximately 3 mm x 80 mm x 0.5mm thick on the long side & 3 mm x 60 mm x .5 mm on ythe short side) on the periphery of the LCD. This is to keep the touch screen from touching the LCD. This is to prevent Newton's rings as also to prevent malfunction of the touch screen. These are an absolute must.
Other than that the touch screens are absolutely the same.
Hope this helps.
