Yes, the wire connecting the motherboard to the screen can pull loose at either end. Most of the time I find that it pulls loose from the back of the screen. To fix this, you have to: open the screen bezel unscrew the screen lay it down gently push the connector in to ensure it's tight place a piece of scotch tape or electrical tape on the wire to ensure it holds in place reattach the screen and then test it by powering on the chromebook If the screen still doesn't power up, it could be the other end of the wire has come loose. or it could be the screen has died.
