Dell laptop backlight only works when I press/bend on motherboard

Texte:

So I've finally isolated my problem with my Dell inspiron laptop. The laptop itself is about 7 years old and pretty well taken care of. About 2 years ago it started having the issue of the backlight dying out, getting progressively worse over time. I eventually stopped using since I graduated.

I thought the screen was the cause but it seems to be a motherboard issue. I first discovered that if I bent the board (lightly) in the corner where the screen cable connects to the motherboard, the screen would illuminate.  I thought it might just be a short or something. Then I checked if pressure cause somewhere else in the board was the fix and this seems to be the answer. My guess is a capacitor or something but I'm hoping someone with some more experience can provide a more concrete solution.

Some videos to show my findings
