Check the battery connector and the battery cable for (even microscopic) damage.

The PW-1 and the PW-2 use different screen controllers (different SoC - the i.MX6 (PW-2) has the controller built-in).

I only know they differ - I don't know about compatibility issues.
So I can't even guess if you have bork'd the SoC controller, hooking a PW-1 screen to it.

But all of the hand-waving about changing screens / motherboard is probably a red herring (other than to indicate that human hands have been inside of the case).

The battery and the battery management have nothing to do with the screen and the screen driver.

Ah, and if you have replaced the battery, be certain that you actually used a PW-2 battery.
