Your Help will be greatly appreciated

I can see my tablet screen through the computer by using moborobo . . . .
so the tablet is not damaged

Sounds pretty obvious: your screen is damaged. Your tablet can still function with a broken screen, although obviously you would need to find alternate input methods. Only thing to really do is to get the screen replaced.
