MacBook Pro won't turn on after logic board replace. Dim green light.

I just replaced the logic board in my late 2011 a1278 Macbook Pro Unibody. It was diagnosed dead by apple so I thought I could replace it myself. So I put it in and it would not turn on. Just shows a dim green light on the charger. I bought the logic board for 250$ off Ebay from a good seller. The board doesn’t get warm at all even after charging for 4 hours so I don’t think it is getting power. Please help me!

A dim MagSafe LED often points to a bad charging logic on the main logic board. So I’m suspecting the replacement board you got is likewise damaged as well.

You still should check the DC-In board for damage. Here’s the IFIXIT guide to get to it: Remplacement de la care de raccordement MagSafe du MacBook Pro 13" Unibody fin 2011 and heres the replacement part if you need it MacBook Pro Unibody 13" and 15" MagSafe DC-In Board. Make sure the small SMT components are not missing or damaged on the logic board.
