@nictrocaster: Could you post the part number of the FPC cable connector?
I broke off the black latch so I want to order one and see if I can replace the latch.
That's a new revision of the same Hirose FH19.

It seems quality for that connector went down from rev 3 to 4. I had 2 pins sticking out of the gate, no way to put them back. I bent it outwards until the center snapped.
(<-- disregard that) rev.3 used some cheap generic FFC connectors and then I switched to Hirose FH19 which is easier to solder and takes less PCB space. I don't quite understand what was wrong with 2 pins, do you have any pictures?

Edit: It's the STM chip that's getting very hot and probably shorted.
I bet that happened after hot-plugging the LVDS cable. Hot plugging fries random parts of the system: backlight fuse, PCH, ThinkEngine, STM chip on the adapter board, maybe something else. Do you think you can replace both the LVDS connector and the STM chip?
I’ve sent you an email, but to update - external monitor works via DisplayPort so it looks to be the STM (I have the tools to replace it).
Not sure if an original internal display would work because I’ve sold it, but display fuses measure OK.
