Air 2 has no power after screen replacement

This was my 4th Air 2 screen replacement and it was a normal repair, nothing weird happened. I cannot get the unit to turn on now. iTunes doesn't recognize it and when plugging it into a Apple charger it shows no sign of life. I pulled off the cover to check the components and found nothing to really be out of place. I used a loupe and took some pictures for you to check.

I have tried several hard resets, the original display and another OEM display. Nothing on the board got hit taking it out. No lights and no sounds from charging it.

I need ideas about what to check.
