I have water damage logic board out of my late 2013 MBP ratina. I am testing through power rails and I am checking my PPBUS_G3H power rail with multimeter. I am getting below finding. I am getting 12.59v for all R5410,R5400,R5440,XW5480,F7700,R3080,C3080,F7140 except this two I am getting 0.05v R5400 = o.ov Q3080= o.ov Can anyone tell me why I am getting 0v for above . anything short in between or what ? Any information will be greatly appriciate.
We should deal with the water damage first. That may fix the issue, and if you don’t address the water damage, you’ll have bigger problems. Disassembly: MacBook Pro 13" Retina Display Late 2013 Upper Case Replacement Electronics Water Damage
