Sounds like the screen is faulty, you'll probably have to take it to samsung/vodacare for repairs...
You have tried a hard reset? : Follow the guideline here:
1. Press reset pin button ONCE (do not hold)
2. Once you see the Samsung Omnia appears on the screen, immediately press the SEND and END key simultaneously
3. Then the screen appears asking you whether you are sure to format
4. Press SEND to format or END to cancel
Hey.
