Hey all,
Have a MBPRO 15" with no backlight. No liquid damage, supposedly just stopped working.
What' I've measured:
Fuse: 12.6v on each side
BKLT_EN: 3.2v
LVDS Pins 389,39,40; all at 29.6v
Figured it was a bad LCD right? Nope, tested an LCD that works fine and no backlight still.
The current sink resistors all measure 0 ohms, getting between 3.2 and 3.5v on them. I figure the LED Driver is boosting fine since I'm getting 29v at the LCD connector.
Bad LVDS connector maybe?
