I had this same problem when I was trying to change my battery just a few days ago.

The cause was as @christophe34554 described: I had broken off one of those small components on the motherboard near the display connector when I pried up the connector.  This was the leftmost of 5 identical parts, each of which has 4 terminals.

For repair, I tried to figure out what they were.  They were tiny little things (about 1mm by 1mm square).  My trusty DMM showed a resistance of around 3Ω through them on the other 4 intact components.  I replaced the broken part with a two separate 0201-sized 3Ω resistors, and that got the screen working again.
