Just replaced logic board, won't turn on.
I just replaced my logic board, but after I reassembled it and connected it to 5W power it wouldn't turn on and the battery disconnect never illuminated.

Hi
Before we think it’s a hardware issue I thing it might be worth reseating all the connectors as iv had macs come to me with this fault before and the issue was fixed by cleaning the connectors with isopropyl alcohol and reseating them
After that it might be worth looking into the hardware side of things
Hopefully this helps
Any questions please ask
Thanks:-)

If you have access to a USB ammeter check how many volts the device is using. This will help diagnose your problem. Where did you source the logic board from?

I do not unfortunately. I got it from ifixit.
