No backlight, tried inverter, what now?
I've tried to fix my problem on my own by following the guide instructions of ifixit. I am having exactly the problem which is described in the Macbook troubleshooting article (The screen is very dark, but everything else seems to be running. If you get in close with a flashlight, you can usually see the image faintly.)
So I bought a new inverter but this did not solve my problem. In my case the backlight is available for 10 - 30 seconds and after that the screen is black and I am only able to get the backlight back for 1 second.
I want to know if connecting my Macbook with an external display via vga and getting an image on the new display...
what would that mean? A working logic board and thus a faulty LCD?
My Macbook is just 3 years old and it would be a disaster for me, when having a faulty logic board. Unfortunately I have not bought an ACPP.
I hope you guys can give me some advice!
Thank you for your help!
I have ordered a minidvi to vga connector and I will check if I am getting a good picture on the external monitor.
Changing the inverter cable was actually not an option for me because I first went to an Apple Service Provider and he told me that the cable couldn't be the problem. Due to the fact that the backlight is gone without moving the display.
But now I will try a new inverter cable!
Maybe it's worth to tell the whole story how the backlight problem started:
My Macbook had only 1 GB of memory and I bought new 2x2 GB of memory. But one of those new memory was faulty. I checked it with rember. Afterwards I upgraded to Snow Leopard and while installing the new OS the backlight was gone. But it was possible to get the backlight back by closing and folding up the display. I decided to switch back to the old memory and downgraded to Leopard but this did not solve my problem.
Yesterday I observed that when using the brightness keys( F1 & F2) I can create for one second backlight. I have to switch down the brightness to zero and then by pressing F2 I can get the backlight back. I repeated this key combination in order to maintain the backlight but then I get a flickering backlight, which only lasts for 3 - 4 seconds before getting a screen with no backlight.
I will post here again when I tried the external monitor/ inverter cable!
So the VGA connector arrived and I am getting a good picture on the external monitor!
Today I observed that the backlight of my Macbook was able to last for more than 30 minutes! But afterwards same problem again.
NO LUCK with the new inverter cable :(
First it seemed to be fixed, since the backlight was available during moving the display which was not possible before. But the backlight was gone after a couple of minutes and did not come back. I also changed the inverter board again but no effect... the inverter board which I ordered for replacing my old inverter was even "worse". Because my old inverter was able to produce backlight for a couple of minutes and the new inverter only few seconds...
