MacBook screen stays black
Hello i have a black 2007 black macbook that i recently started having issues with. The computer was running ok but one day it was sitting on a shelf and fell off. When I started the computer up after the fall I had to apply pressure to the screen to get it to turn on. After awhile the screen would not stay on it would fuzz out, if I applied pressure to the screen it owuld come back but immediately fade to black again. I thought the issue was a bad lcd so i replaced that, but it did not fix the problem, I had a working lcd but no backlight. Thinking the inverter was bad I then replaced it, but this had no effect either. The last thing i replaced on the computer was the logic board but this did not fix the problem also. The computer does work on an external monitor, and what i have noticed is that when I plug the vga cord into the computer the screen will display a picture but then goes black right away, it does the same thing when I unplug the vga also. The only thing I have left to change is the inverter cable, but I am not sure if this is the problem as the display does come on and off when plugging in the vga.
Is this a good question?
