A few days ago I attempted to troubleshoot the problem using the excellent step-by-step guidance found on this site: MacBook Core 2 Duo Front Display Bezel Replacement.Ĭompleting steps 1 to 12 permits removal of the track pad and keyboard, exposing the internal circuit boards and wiring. of arc to sometimes have use of the screen. For the last couple of weeks I've had to repeatedly open and close the screen and carefully finesse the last 50 deg. any more than that would be hit-or-miss. The backlight would remain lit when the screen was opened less than about 45 deg. Good luck with the DIY, definitely among the most challenging (but most rewarding) that I have attempted doing! One other note is to make sure that your new lamp's cords are long enough in order to reach the inverter once re-assembled. I would recommend using one of the step by step guides for the LCD panel brackets, and once you free the LCD panel, just remove the 2 bottom screws (one on each side) for the housing cover, and then you have access to the actual housing.

Re-assembly is also tricky because you need to use high temperature tape after you install the new lamp on the LCD panel, and then re-assemble everything back correctly (especially the wires). I must warn you that it is an absolutely daunting task because not only do you need to remove almost 30 screws to get to the LCD panel, but you have to carefully remove the tape at the bottom of the panel and carefully extract the lamp from its housing. The long and much cheaper way is to replace the actual 13.3 inch WXGA lamp located at the bottom of the panel. The short and more expensive way to fix this is simply replacing the entire LCD panel - which I would not recommend. I just changed mine and all works fine now. This is definitely the WXGA lamp, the light source for the LCD panel.
