Schematic of A1286 (EMC 2353-1*)

[terrypen]

First off, I'm new to this board repair stuff and Macs in general.

I've been watching Rossmann, Jessa, and STS Telecom videos!

I have a donor board that I need the schematics for.
Apple MacBook Pro "Core i7" 2.2 15" Early 2011
Identifiers: Early 2011 15" - MC723LL/A - MacBookPro8,2 - A1286 - 2353-1*

I have an 820-2915 schematic and that's not it or close enough for a newb.

Any help would be most appreciated!

The board inside a MBP 15" 2011 is actually 820-2915.
It's gonna have a dead GPU.

They said it had no power, but it looks like a few chips have been tampered with.

U8400,U8450,U8500,U8550 Graphics ram?

and U8000 GPU

So, are you connected to my microscope???

Pretty common, I presume! haha

Thanks,

Yeah the AMD GPU dies all the time on 2011 Mac…
Maybe it is just signs of a previous replacement…
But if it has been reflowed, it may have shorted balls.
(it's pointless to reflow them and will do more bad than good)
