Location of the WLED driver

Can someone tell me where the WLED driver on this Macbook Pro? This is a Macbook Pro 15" 2.8Ghz Mid 2009 EMC 2324. I have also included pictures. Thanks in advance.

I'm sorry, but I couldn't find the last three digits of my serial number.

Kevin, not sure where you posted your images:-) use this guide Aggiungere immagini a una risposta esistente to post your images with your question. Also, it will help tremendously if you give us the last three digits of your computers serial number.

Kevin, for the EMC 2324 as it shows on the images you uploaded, the LCD backlight driver has reference designator U9701. It is a LP8543SQX manufactured by TI. the datsheet is available right here. The part itself seems to be a bit hard to come by, but it is available :-) Hope this helps, good luck.
