So this project has been a little disasterous for me so far.. Was a routine Macbook Air LCD-only replacement (done plenty before) but after installation of a new LCD the backlight appeared to be out (could see apple logo on the LCD). I replaced the backlight strip because i had some scratches on the cable thinking that may be the issue but still same problem. I then decided to order a new lcd panel only to find that to not work either. At this point I knew it was probably board-level. After testing around I found 8.1v on pin 3 (gate) of the transistor and 8.4v on pin 4 (source) of the transistor (Q9706), but nothing going through. nothing on the board looks damaged and it had backlight before with the customer's bad LCD. Is the voltage on the gate low enough?
