When I was testing the coils I had already removed the LB from the case so the battery has not been connected. I did have the charger plugged in when testing the coils but something definitely happened because amps are now only running at 0.02 to 0.04a.
I don't recommend you to spend more time with this board.
You did something wrong when swapped the screen panel.
Do not insist, as seems you already made more damage after that.
I hope you don't take this as an offense.
Just need someone with more experience to try and recover it (if still possible).
