No LCD backlight, backlight is on for 2 seconds when booting up

My MacBook's backlight doesnt work, i can see the screen when i hold it at an angle towards the light and it works perfectly when connected to an external monitor. The wierd thing is, that the backlight comes on for roughly two seconds when i power on the MacBook, but only the right half of the screen is lite up and there are about 6 different coloured vertical lines over the screen.

i did a tear down on the machine, i flexed and moved the inverter/data cable around, no change in the backlighting situation so i dont think it's any of the cabling. I also removed the inverter board at one point and the lcd screen was still on.. just no backlight of course. So i dont think it's a problem with the LCD or cabling.. but im not too sure. Any suggestions??

Someone please help me solve this, email me at

This sounds like an inverter problem to me. I would replace it. Here's how: MacBook Core 2 Duo Inverter Replacement

It can also be the Cabling, so have a look at that before buying parts.

i have almost the same problem with one difference: backlight is generally working, but only at lowest level. as soon as i light it up, it breaks down. if i bring it back to zero and then 1 up, it comes back.

when the laptop wakes up from being closed before, it usually as well breaks down and needs to be resetted to lowest level as explained before.

so i'm curious whether this could really be the inverter, as most people say that a bad inverter causes completely dead backlight. and it doesn't seem to be a mechanic (cable) problem, as it has nothing to do with the screen angle. but sometimes when reseting it from 0 to 1 it is flickering and crashing then again, so i have to try it 3 or 4 times until it works.

thx a lot in advance!!
