Your problem extends very far from the average persons repair.  Your backlight problem is controlled by a tiny chip called a WLED driver it is a Quad Flat No Leads chip or QFN which is very difficult to solder onto the board. Of course the best option is a logic board repair service or whole new mobo.  I have soldered 3 and only did it right once. But now we are talking component level repairs :)
