"MacBook suddenly has inverted/flickering vertical strip on the screen"에 답변Clean the contacts of the LVDS cable with a pencil eraser on the logic board side and on the display side. This cured my screen flicker by 95%. With the LVDS cable connected to the display panel and the display panel not quite seated down into position yet, slip the first layer of 3/4" x 2 1/2" strips of thin, doubled-up cardboard down in against the display housing behind the inverter board. Next slip the second layer of thin cardboard strips between the inverter board and the lower metal retaining bracket (the thing that lives behind the display bezel on the bottom where the two smallest screws go). Now the inverter board is sandwiched between cardboard on both sides. In may case screen flicker was cured by 100%. By the way, I tried using the heat gun at 200ºC on various parts of the inverter board, shielding the display panel with aluminum foil to protect it from the heat. This technique showed no improvement in screen flicker whatsoever.
"MacBook suddenly has inverted/flickering vertical strip on the screen"에 답변After disassembly I cleaned the contacts of the LVDS cable with a gummy pencil eraser on the logic board side and on the display side. The flickering problem showed 95% improvement. Next I shielded the display panel with aluminum foil on both sides to dissipate heat and then heated up the inverter board with a heat gun at 200ºC, working one section at a time. From this there was no noticeable improvement, but on reassembly I realized that screen flicker would result from light tapping with the flat part of the plastic spudger under the display panel between the metal plate that retains the inverter board and the inverter board itself (essentially tapping a bit in the horizontal slot to the left of the bottom left display retaining screw). Okay, problem area located. I solved the problem by removing all 6 display retaining screws once again and then shifting the display upward. I made 3/4" x 2 1/2" strips of thin, doubled cardboard and then dropped them down into the slot on both the left side and the right...
