i900 touch and sound not woking

[Guest Slishard]

Hi, I have Omnia 16GB version.

I use him a lot and this is cause of his warming. One day I was shooting pictures and with gps geotagging option and suddenly he stopped reacting on touch. I tried everything, soft reset, hard reset and nothing helped. I thought that this was the only problem but when I tried to plays some songs the sound was dead too(I noticed that first time when I turn him on also)

Did anybody had the same problem or know how to fix it?

Thank you all
