Loose connection to screen on mainboard
I am trying to repair an ASUS X407UBR and found that the connection to the screen on the mainboard is sensitive to touch. If pushed, the screen will turn off, as can be seen in this video:
It seems stable enough without the casing, but I am afraid the connection will be lost if I close it back up.
Is there something I can do to fix this? I have access to a soldering iron, although not much experience using it.
EDIT: As requested, pictures of the two ends of the connection:
The board plug is definitively loose on the left side and that's also the side that is pressure-sensitive. Funnily enough, connection is lost when I push it back towards the board.
Is this a good question?
