Short on PPBUS_HS_CPU?
For the last while I have been working on a MacBook Pro that was lightly water damaged and I’m in the process it of repairing it
Something really wierd has just happend and I’m wondering if I have got the correct idea before to start removing things to get rid of the short that I have
So here’s what happend:I was replacing components quite normally and testing them as I went along until I put one component on and noticed it was shorted to ground ,so I thought it may have bridged to another component beside it ,so I replaced it and still has the same issue!
The thing is though it’s not just that component that’s shorted it’s the whole rail from what I can see
I can’t understand how it just randomly happened,
I did think it could be to do with one of the cpu mosfets as there are 2 that have one on the little pin/legs missing but that still doesn’t explain why it randomly started
Is there any thing I should shock before I remove the mosfets to see if the short persists like check any known components for a short
Perhaps I reflowed something like the cpu mosfets and there is abridge under it
any help is greatly appreciated
