Hi... Before replace the display check the front display frame unit, maybe the cause of faulty touch screen, this because the frame and the display are separated by a thin layer film that maybe spent on several point of contact of the frame, so the frame became too close and stay always in touch with the screen making it unresponsive.
Fix is simple: disassembly the front layer and replace the thin layer with a new one, you can use a thin adhesive foam, buy it in your hardware store for less than 1 Eur/Usd.
Hi
this is typically a problem of failed touch screen, which you may have to get replaced :(
(a common prob with HTC phones i've seen)
a touch screen can be damaged due to many reasons excess pressure when in pocket or even static electricity
hope this helps
Hi. You need to replace the digitizer. This happens to many touch screen phones from all brands.
you can purchase from:
http://cgi.ebay.com/US-NEW-HTC-TyTN-II-TILT-8925-TOUCH-SCREEN-PAD-DIGITIZER-/350435156469?pt=LH_DefaultDomain_0&hash=item51979021f5
After purchasing you can have it replaced in a cell repair shop or similar shop. Or you can chose to replace it yourself.
Thank you for using fixya.
In the past, some HTC devices have been affected by problems with touchscreen alignment, but you shouldn't have any problems with the TyTN II in this department. The 240 x 320 display is clear and bright and also seems not to suffer from yellow colour cast that has been common on earlier devices.
The keyboard has a nice positive action to it and works extremely well. It's virtually identical to the HTC Herald, and very similar to the HTC TyTN. Holding the device in both hands it's easy to type at a fair rate using just your thumbs.
Finally, to insert a SIM card you have to slide the keyboard open and then look on the rear of the screen. Under a flap you'll find the SIM card slot.
