Usually the ribbon cable connection that powers the backlight is the problem.If you remove the four screws in the back and take off the back cover. (note that there are two tabs on both sides of the cover half way up)You can see the white ribbon cable on the left above the battery back housing. Gently wiggle it and see if the backlight goes on. The cable is attached with a small brown insert that holds it in. It is removable so you might be able to get an electronics shop to replace the cable connection or the cable itself.

My Uniden UM525 is blowing fuses the instant I plug it in. I don't know what happened to it but I'd like to fix it. If anyone has any ideas I'd love the assistance. Thanks in advance,

Hey Marked,

First check the diode in the B+ line . Probably it is shorted due to a reverse polarity connection.

Take it out and test without the diode if it works replace it diode.

Good luck.

Universal Remote software?

You cannot find remote software for E-125 simply because the range of the IR emitters on E125 is simply too short. If you are willing to di some surgery on the device - switch it for a higher range one from say E-100 - the earlier versions software should work on E-125 also.

CASIO E-125 has no backlight

Pretty common problem, and is normally one of three possibilities: 1. Ribbon cable that connects the backlight daughterboard to the motherboard connector has gone bad, or contacts oxidized. 2. Daughterboard itself has gone bad... 3. Power problem or cpu problem not activating upon powerup. Not as likely. 4.The fluorescent tube itself may has blown. The cure: carefully disassemble your 125, clean the ribbon contacts on both ends of the tiny ribbon cable, be careful, it is very fragile. If that doesn't work, find someone who has a E125 and swap out ribbon cables and see that works, that will at least tell you if the cable is bad or not. If that doesn't work, swap out daughterboards. If that doesn't work, sell it for parts on EBay and buy a new one, because anything else will probably be too expensive.

Casio not reading CF card after using it in Desktop PC

Try another CF card/accessory in the slot to determine if the CF socket on the E-125 is not damaged. Also run scandisk on it while plugged into the card reader on yopur PC. There have been issues with 128 mb CF cards manufactured by SanDisk (who are OEM suppiers to several other brand names also ) randomly malfunctioning. Inspect the pins in the CF slot on the PDA to see if any of the pins has been bent/corroded. Hope this helps.

Anyone experience problems with an overclock E-125?

There are some overclocking programs available like through or even hardware fixes. The one by jimmysoftware is for the iPAQ only. iPAQ Overclocking software I would strongely avoid doing the hardware fix. The overclocking applies only to the processor itself and does not take into account the I/O from the the processor to the various other hadrware components. Some games, video, and apps may perform better but anything hardware related like PC card or CF cards that have a function like modem, networking etc. . . can run into timing related issues and not function. At least the software version can be easily removed. Good luck
