Try to remove the battery from the handset, the battery is located at the back. Open the cover to access the battery and then remove it.
After removing it press and hold down the power button on the phone for 45 seconds without the battery and then insert the battery and try to use it.

Reset the handset by removing batteries for at least 45 seconds fixed the problem however if the screen is still stuck then it could be a hardware problem. Hardware problem can only be fixed by the workshop repair.
Please call them first and then proceed to take the handset. As per my expertize the problem seems to be not getting fixed by device reset which we have already tried.
