My touch screen has stopped working? how can i fix it? only the centre button works ans none of the touch pad does? it suddenly happened i never dropped or got my phone wet????

If the touch screen has stopped working it probably has a bad digitizer. You can buy that on ebay with the tools as well for about $15.

I own the Kenwood DNX7140 navigation system. Periodically the screen says "Software Update Complete" and teh system locks up. I have never updated teh software though. What is wrong with it?

You need to update your software. Garmin does this through a downloaded file you burn to a CD. You then do a firmware update to the Kenwood from the CD. Instuctions are on-line at:

Iphone got wet and touch screen will not work. Can this be fixed

Yes, if you bring it to the apple store, the will basically replace the phone for you for a charge of up to $200.
That is there basic response to iphones that has gotten wet...
If they determine it is another defect not associated with getting wet, and the item is still under warranty, they may replace it at no charge.
Hope this helps.  Let me know how it all turns out.

Screen touch is not functioning

A general fault is that the touch screen or its control devices has failed. In some cases, the ribbon cables or the pressure contacts between the screen and its controler are not making good contact.

If there is an electrical fault, the fix is to replace the touch screen, and its controler. In many of these types of phones everything is on the main circuit board. The general fix is to replace the main circuit board, or to replace the screen assembly.

The main cause of failure for these devices is dropping the phone, or getting it wet.
