Have you tried a reset by holding the power key down for 10 seconds?If that doesn't work you can try removing the battery for a few seconds.
I had a similar problem with my E7, it was dead and wouldn't respond even when I plugged it into my PC. But once I had removed and replaced the battery it was working fine and its not gone wrong since. Here's a good guide on removing and replacing the battery

There is a linking cord for the display main panel to the main board and this could have snapped. SO it is best to take consensus with the Nokia support center , get estimate and replace.
