MacBook air 1,1 (early 2008) graphics module soldering

Hello!

I have a pretty big problem. My macbook air starts and runs and works properly, but it doesn't show anything. I mean, the LCD is black.

So i went to an expert consultation and he said, that the graphics module is faulty and suggested to buy a new logic board. I found out, that this model macbook air has an Intel GMA X3100 graphics module, so i tried locating it, but effortlessly. So my question is: is it possible to solder the graphics module off the logic board and replace it with a new one? And if yes, then first how can i locate the graphics module (i didn't find any schematics on the web) and secondly, what kind of equipment will i need for that? (I heard that the newer logic boards are with multiple layers so maybe some hardcore machine is needed for that? I would appreciate any information leading me to success.

Thanks,

Ott
