Why the background light still not work?

Hello all, here is my problem, the light from the screen started to do not work, the screen was working since I was able to see things with an external light, but there was no light from the screen itself.

So I searched and found that it was the inverter that was dead so I ordered one and replace it.

But the problem still there, wich confuses me a lot.

I believe I might have to buy a new inverter cable - may be the old one is domaged or something - but I know it might be something else, so before buying anything else I wish to know how I could test, and wich ones, the part before buy them, for exemple with a multimeters.

Thanks you for reading and maybe helping.

Hi, thanks you for your help, I can't find which ones you want to know?


Sorry, I meant the last three digits of your serial number


No problem, here there are : VJ1


Does this look about right :"Intro Date: February 14, 2006 Disc Date: October 24, 2006

Order No: MA464LL/A* Model No: A1150 (EMC N/A)

Subfamily: MacBook Pro (Glossy) Model ID: MacBookPro1,1

Std RAM: 512 MB, 1 GB Std VRAM: 128 MB, 256 MB

Std Storage: 80, 100 GB (5400 RPM) Std Optical: 4X SL "SuperDrive"


The last clarification that might help is, do you have the part number from the new inverter? The reason why I am asking is that I am trying to cross reference all the parts to get the data sheets, so you can do some measurements.

omzart, your panel is a Chi Mei N154C1-L02 and the datasheet is available right here. This will give you the values that your inverter is needing to supply the panel. Next step is to see where you can measure those. The part number on your inverter shows 612-0038-a and this corresponds to a MacBook PRO A1151 LCD Inverter. Yours is a MBP A1150 and the inverter part number for that is 612-0020-A or a 922-7191. That one is only compatible with the 1.83GHZ, 2.0GHZ, 2.16GHZ, and 2.33GHZ models. It is not compatible with the 2.2 GHZ, 2.4GHZ, 2.5GHZ, or 2.6GHZ models. Since your processor is a 2.0GHz the right number should be 922-7191. Of course, there is also the possibility that your backlight fuse is not working. The fuse should be marked as F9800(?) on your board. It is a small SMD component and sometimes it has a "white dot" or a "P" printed on it. Once we find that, check it for continuity. If it needs to be replaced, it is 2A 32V 402 package fuse and it is available at places like Digikey.com and the part number is P15123CT-ND. But start with the right inverter first. Hope this helps, good luck.
