My tablet wouldn't turned on, but now, It is turning on but the screen is not working. The tablet itself is working, sounds, wifi, even Touch screen.
But the screen, is just a gray screen with a minimum brightness.
Looks like a dead digitizer to me..... I had to return a 5 day old TF701 and it looked just like your picture there. If you can return and exchange it with your seller, do that. If that is no option and you still have warranty fill out an RMA at Asus and send it in.
You should get all your files off the tablet and Factory Reset it before you do so. MTP should still be working, so you can use your PC to copy everything over.
Another option is to use Asus Backup to back up your stuff and restore it to the new or repaired tablet. You would have to connect the tablet via HDMI cable to a TV for anything you do on the tablet and believe me: It's a PIA to hunt and peck for just the right spot to touch on the tablet's screen while looking at the TV.... But with some persistence a high tolerance for frustration it can be done.
You don't need a motherboard - just a digitizer.
You could try to find one on ebay from someone selling TF700 parts.
You find tear down instructions and videos on ifixit.com. Also search YouTube for instruction videos. Check them out and decide if you think you can do it yourself. Or you have to find someone to do it for you.
Asus will do it, but that is going to cost a pretty penny.....
