      That is external...hdmi port....The original lcd is broken. Gpu on laptop is gtx1070. The funny thing is that that upper right square and bottom is working fine. So maybe a one or two gpu ram moduls gone bad...but not sure.

          Not 100% certain but the fact your getting image in 2 corners leans more to VRAM .

          Did you start with replacing thermal paste?
          If no change...

          your best bet its start by
          Reflowing all vram see if problem clears up .
          If not replace 2 at a time from donor, buy stencil.

            for the future record it was one bad vram chip. I was also lucky...second one i replaced.

              VREF 2.1 V

              As far as i can understand or is a problem with the memory Controller ( in this case there is no solucion?) or for some reason the vram do not have Voltage. By the way i...

              TCL 55S425 few horizontal lines, potential failure on both side of panel/buffer board
              by howardc64
              All left and right refers to looking from rear of TV (or looking from front with TV upside down)
              • TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
              • Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault
