  • 820-3787a no backlight image can be seen liquid damaged.

    Gday guys I'm using schematics for 820-3332 so hope layout is similar. unit has corrosion on c8513 PP1V5R1V35_S0GPU would this cause no backlight? because I wouldn't think so unless this rail must be complete before backlight shows up. or is it as simple as replace backlight driver? I'm getting 0.560 Diode on L9000. I'm not 100% familiar with this retina model so any help would be great. I'm getting 12v on both sides of the fuse.

      Yeah get the correct schematic first. What voltage do you get on BKLT output on the bigger BKLT caps?
