Re: MacBook Pro 820-3332-A (2013 Retina) liquid damage

So I got it up and running again but it's back to where I started, so those caps either weren't the problem or not all of the problem.

What it does now is it'll sometimes boot, and after 2-5 minutes it'll just go black. I'll have to hold the power button to fully turn it off before it will wake up again. I don't believe this is just going to sleep.

Other times it'll chime and stay at a black screen (no backlight at all). I'll have to power cycle it and it'll start up 'normally' again after a try or...

Oh man I feel dumb. I didn't even know about the PDF. It all makes sense now.. Thanks!

Ok, so those are 10uf 16v caps. I pulled two 10uf 16v caps off a donor board and put them on.

The closest match I could find on any of my donor boards was 10% caps where the originals were 20%. That just means the new ones have a tighter tolerance, right? So that shouldn't cause a problem?

I still get no fans though, where as I did before I took the original caps off.. hm

K, done. Still looks clean there, but no change.

When I pulled those caps up at C7536/C7526 it stopped booting at all. Before that it would chime and attempt to boot before crashing, so that made it worse.

How can I find out what kind of capacitors those are so I can make sure I'm putting the right thing back there? One was kind of cooked and there's no markings on them so I just pulled something similar looking off an old board but clearly that didn't work

Re: MacBook Pro 820-3332-A (2013 Retina) liquid damage

The board looks mint in that area, am I looking for anything in particular there?

I should mention that since I took those caps off at C7526/C7536 it doesn't turn on at all anymore so I've clearly made it worse...

Hey guys, I'm trying to repair a 2013 Retina MBP that has some liquid damage.

This MacBook will turn on and work "normally" but will frequently just go black (but the fans would keep spinning) and will sometimes chime but stay on a black screen. I ran the full diagnostics with ASD 3S155 and everything passed. It will rarely get to the desktop and I can't even get the High Sierra or Sierra installers to finish booting.

So, I took the board out and checked it over for damage, and found a small amount of corrosion on the back. It looks like something might have...
