My mac started to give some flicker problems, until it became unusable. I opened the frame of the LCD and I noticed that by pressing the flat DX, the screen returns to work well. The computer has not suffered any impact. Is it possible that it is overheated too much and there are problems with welding? https://youtu.be/-wc-unX0q0o
Based off the video you posted, either the LVDS flex cable or the daughter board have suffered some kind of damage.
