a1502 dead logic board

Hello Guys

Macbook Pro Retina A1502

COMPLETELY DEAD

No water damage, it simply didn't turn on again.

MagSafe is working normally.

However I think I should go over the power rails to fix this BOARD, right?

Is there anyone that can me give the next steps here?

Find power aliass on your schematic, start testing power rails, I would start with pp3v3_g3h. You will want to use process of elimination, by that I mean find what power rails you have and what are missing, then work your way backwards to find the source of the issue. Remember when testing rails don't go from A to Z, start with point A then test point Z , then point B then point y and so on till you find the issue.

Still looking for your answer about REMOTE logic board repair tutoring.

Anyways.

I will go A to Z, cause at NOW my mind cannot understand why go to Z if B, C or D can give me the wrong voltage for example.

I mean, by logic, if B is an ISSUE the rest of the BOARD will be giving me wrong values. I guess so!

Forza if possible reach me by WhatsApp +55 53 9 9705 9883

Thanks!
