Sony Xperia lt26i screen issue

[humbertob]

Hi Sony,

So heres my problem. I'm trying to find out what is wrong with my Sony Xperia lt26i because the touch screen does not respond. It starts perfectly and the operative system starts as well. The touchscreen is replaced by a new one already but the problem stays the same. I am unable to unlock the mobile and start using it. Since it is not the screen it should be something else..... Do you have any suggestions what might be the problem? Thank you for your suggestions!

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

I suggest that you try to repair the phone software using PC Companion..

Before repairing your device you may want to backup your information first. Check out this topic for more information on how to.

If the issue should still remain I think that this needs to be examined and fixed at a repair center. For more information about how to submit your phone for repair and where, contact your local support team.
