Horizontal lines on top left of display. LG 49UH668V

So my screen developed a flicker around a week ago, however this problem was solved seemingly by removing all cables from the motherboard and plugging them back in, I think (I also pressed the heatsink down onto the main IC) I’ll link the related thread below, also if a moderator feels this question should be in the other thread delete this thread and I’ll make a subsection in the other thread regarding this issue.
