MacBook's screen doesn't turn on when I boot up the machine.

HI, "Mayer" is absolutely correct. It is an isolated problem, a new replacement screen maybe in your future but first do as suggested by "Mayer" and post the results for further guidance.

Hi there, in some cases that screen data cable can be repaired (depending on what you find). I would not advise doing to much with it because it is so hard to see the wires clearly with the natural eye. If you have a DVI monitor that you can utilize then use it. If the screen comes up then you are in business and you can feel assured that the issue will be between that data cable or the screen (I doubt that it would both).

Hi Mayer,

I also had the same issue as the person above. I am able to see the screen if I shine a light.

I bought and replaced the inverter and the screen is in the same state.

Would you suggest I replace the Display Data Cable?

Hello there, for this kind of problem the cheapest and easiest way to go is to GET A NEW SCREEN DATA CABLE. Now if your problem still continues then the chances are is that the screen itself is bad (it is always a possibility that the video chip could be at fault but since the external monitor works with any issues, then I would rule out the video chip).

Parts ordered.

Dreading a 45 step tear down, but can't throw money away ;).

Thanks Charles.

I've found resetting the pram to solve this on a number of occasions, got to say it's unlikely to be the data cable and if you've tried the inverter i'd be very inclined to say it was the screen.

i have partially the same problem with my macbook 13" . I turn on the unit and the screen turn on inmediately but seconds later the screen go off. I already change the inverter with no positive results. Note: When i use the computer with an external device as my ipad the macbook screen works fine, so probably its not the screen. Should i change the data cable?
