Hi guys,
(Firstly I want to apologize for my bad english)

There's a thread on Disscussions Nokia which about exactly my problem.

http://discussions.europe.nokia.com/...em/td-p/746660

My exact same problem started at 20th April 2011, when I was travelling to very cold place. All evening and night touch screen worked fine and next day it broke. When I was touchig screen, I was finding it very steamy. Like touching a window in winter.
During next month, I didnt give it to reparation. I've tried some software solutions. I've dried it (both with dry rice and heat) I've read all i can found threads on internet. And I've searched solutions. In the end I give it for repair. They replaced touch sensor. (and they took my 60€ ) And gave me back maya lubimaya
About 2 week works fine.
But yesterday Same problem occured again Repairement service has gave me just 15 days warranty and same time warranty ended, touch screen broke What should I do? Probably even my old touch sensor was working fine.
What part could be damaged? Why? And what can I do? I can't resist to throw it to wall.
(And I dont want to mention what erratic problem is this. Whenever I take it to service it starts working fine. I couldn't convince them twice )
Thank you for reading

One week after second replacement and same problem is happening again. Repairment service (or I) is gonna be mad.
