Take it to the manufacturer or the nearest retailer. It is not a problem you can fix yourself.

It will depend on what has gone bad. If it is just be a loose flexible PCB /cable connection between the screen and the main board or the screen it self may have gone bad. If you are comfortable with small pieces of electronics and have some electronics knowledge, you will have to open up and play with the unit to see what has gone bad. - Neeraj Sharma
