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?
Thanks
I think this might be the location of 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
