Screen comes on for nano second then goes off again

I have replaced the screen a couple of times. The first time I thought it was a dodgy screen so I ordered another and it does the exact same thing. When I press either the power or the home button the home screen appears for a nano second then goes off? Tried reboot via iTunes etc but nothing. Any ideas?
