Backlight not working board level values included
The backlight on a customers Macbook Pro is not working after a small amount of liquid came in contact with the lcd connector. I do a lot of micro soldering work on iPhones but this macbook is sending me in circles. Heres what I have:
BKL_EN = 6.4v
Fuse = Good
Pin 3&4 on LCD conn = 16.3v
Diode mode on pins 3&4 = .531
BLK_PWR = 6.4v
I am wondering why I am not getting enough boost to send it 25v+
Any help would be much appreciated, please don't just say "Send to apple". I am here looking for a board level solution to the problem.
