Where is the location of the back light fuse 820-3476-a?
I recently received a Macbook Pro A1502 Retina liquid spill with logic board number 820-3476-a. Unit boots up but no back light. Does anyone know the location of the back light fuse and wled driver? Crazy thing I had it working fine however when installing the OS back light just went out. Also how many volts should I be getting on pin one?
I think this might be the location of the fuse
Bu iyi bir soru mu?
Post some top and bottom view images of your logic board with your question. Adding images to an existing question
yes F7700 is the fuse
its probably fine though, they rarely blow even under liquid damage. start probing U7700 pins 17,18 and 5 what voltages do you have
