I turned my tablet on and all was working ok then all of a sudden the screen went like white/grey all over. It's not been knocked or dropped and is always protected in a case at all times. What has caused this to happen? It is only 3 months old.

Hi,
This is a problem with the Lenovo . You could try a hard reset to restore it to factory defaults - you will lose all your settings and data.
Here is a link to show you how.

If it doesn't work after that, given that it is only 3 months old, contact the manufacturer about a warranty repair or replacement.

The screen is absolutely blank so can't see or get to the settings.

You can't even remove the back on the device.
