Touch screens does not always work

[gjagils]

Hi,

For two days i have some screen problems. My touchscreen does not react on touch. If i use the buttons it works but on the screen it doesn't. Sometimes it does work for a few minutes.

The buttons always work (but ther are just a few buttons :( )

Anyone knows what to do?

Have the same problem. The touch screen goes dead but the buttons below works.

Anyone knows how to rectify this problem?

I had a HTC Touch earlier also and had to give that for repair for the same problem.

Anyone found a solution to this?

My new HTC also now is facing the same issue. The touch screen has gone totally invalid. The bottom buttons work but the touch screen does not. The other big problem now i have is that the phone is locked and i am unable to unlock it.

GOD, if there is a GOD, save my HTC.

I presume you've done soft resets to the phone and it doesn't fix the problem.

Have you flashed any ROM to your Touch? What ROM did you flash if you have? See if it's a common problem with flashed ROM's.

If not, and you're on generic ROM, try to do a hard-reset and see if it fixes the problem. (Hold down both green and red button and poke the reset button while still holding down the 2 buttons). You will lose all the data on your Touch.

If doing a hard-reset on a generic ROM still doesn't fix the problem, then I'm afraid you have a HW problem. Send it in for repair if it's still under warranty.

well u can also try this, it may be because of pressure setting for the screen

"install a reg editing software like PHM and go to HKEY_LOCAL_MACHINE and then DRIVERS and then TOUCH PANEL; now change the value of PRESSURE THRESHOLD. Remember to increase the valur only, try doubling the value acc to ur need"

If you don't have any warranty and a hard reset didn't work (note if you hard reset and it doesn't work you will be stuck at the screen alignment) then you may be facing a defective digitizer. If you are brave you can take a look at this link (complete dissasembly of Elf)

to study how to take your device apart to replace the digitizer yourself.
