Why is My back light to LCD display is not working?
I have a Macbook Unibody A1342 and the back light to the LCD display is not working. I originally bought this to repair and resell and was aware of the problem because the previous owner mentioned them. I looked up all the guides on this site and a few youtube videos and came to the conclusion that it was the fuses that were out because I could hold a light to the back of the laptop where the apple sign was and see the macbooks home screen and wallpaper like that. Also when I looked at the logic board I saw "gunk" around the fuses. I proceeded to replace the logic board but that did not fix the issue. I then replaced the LCD display and that did not fix the problem. I finally replaced the LCD LVDS cable and Im STILL not getting a light in the back of the laptop. Does anyone out there know what could be the problem here? Again, I've replace the logic board, LCD display, and LCD LVDS cable.
Thanks in advance,
