You should have the LVDS cable connector checked out. We see these getting ripped off all the time when the display leans too far forward, or heaven forbid, falls off. In either case if the connector is separated, it will need to be resoldered by a tech with good soldering skills. Delivers where you’ll spend your money, because the part is under $10.
Note, you may have damaged LVDS cable as well. If there’s the slightest bit of bent pins on the ends, just replace that ribbon cable.
Good luck.
