Touch screen not working

The person who sold me this said the screen worked sometimes. It does not work at all. I have done everything I can think of--hard reset, cold reset, cleaned the screen, installed all updates. Nothing has worked. Any ideas? Is there an adapter for the serial output so I could attach a mouse?

Re: touch screen not working

There is a program called Tascal Regedit 7.0 which helps to get the touchscreen software working again.

How do you fix a touch screen that does not respond? I have done a complete reset and still nothing. Thanks.


Have you already performed a clean reset? You might know that it will restore your device to its factory settings, thus deleting everything you have installed, as well as your personal data and settings. So, it is strongly recommended to backup your data beforehand.
Anyway, to perform a clean reset, press and hold the Calendar, Power, and Messaging buttons, and, whilst keeping them pressed, press and hold the reset pin with the stylus pen. When your device restarts, release the buttons and the stylus pen from the reset pin.
Hope it works for you.
Cheers! Carlos

The touch screen does not work. what can be done?


Are you using a screen protector? Because, in the manual, it warns that any screen protector used, will reduce the touch screen's sensitivity. But if the touch screen doesn't react at all, then it means that it's broken.

You might want to go to LG's website for support. :)

Touchflo of HTC Touch 3G won't launch


Hi. TouchFlo is the special today plugin for the HTC devices, and as you realized, you can still use all functions of your PDA without. I think there is an error in the installation of TouchFlo (There can be a bunch of reasons, we have to know everything you did with your PDA in order to guess them), but there is a safe solution for that problem, you can backup all your personal data and software to your PC, then you can hard reset your PDA to its factory default settings. That way both your phone and the TouchFlo will work. In order to hard reset your PDA (after the backup of your personal data), you can follow the steps in this link: (http://www.hardreset.eu/htc_touch_diamond_hard_reset_soft_reset_en.html). Hope this helps.

Stylus not working when touching screen


I encountered this problem today, and I have figured out a solution!

Switch the Wireless switch on the bottom of the Pocket PC to the Off position, then back on.

Voila, your touch screen should respond now.

LCD/digitizer replacement


Unfortunately, when it comes to touch-screens, it's much more difficult to fix.

The reason being that the screen is placed in the chassis of the device - with precision, so that none of the parts in the device or the chassis/cover of the device itself is applying any pressure to any point on the screen.

If there is any point on the screen which is being pressed by the cover of the phone or any part of the phone such as a wire or PC board, the screen will be reading TWO inputs whenever you push a button on the screen. Most touch screens will lock up if it detects two points of pressure...or it will pick one input and run with THAT one. (Hard to say if it chooses the first or the second input.)

I have a Dell handheld PDA that I can't put the cover back on as it works sporadically when I tighten the screws back down. I know the general region where the pressure is being applied, but no matter what I have done, it just won't work. (It's not worth my time, so I haven't really continued working on it for some time now.)

Sometimes when I flex or bend the chassis of the PDA and I use the stylus on the screen, it'll work for a while. But then you grip it in a certain way and it starts going crazy all over again. When I bend the chassis by twisting it a bit, it releives the point of pressure and I'm able to use it normally for a while. Sometimes I tap the sides of the device to knock the screen back into place. (Although that can be harsh on the device.)

Quite honestly? I would take that phone to a service center and either have them service it or replace it. (But you most likely voided any warranty you still had when you opened it; if any.)

Not much that can be said for it unless we could actually physically inspect it. But this is the internet. :P

Try jarring the screen or inspecting the bottom side of the front cover to see if there is any point that is touching the screen when you secure it. Try removing the screws in certain, contained areas in a slow manner to see if releiving pressure in those areas might show you where there may be something touching the screen. Take it from there. Might consider using a file to file down the area that is touching the screen.

First and foremost, though... Just check to see if the screen is centered right where it's supposed to be.

Good luck with that. I hate touch screen repairs. :P
