i checked LE80 and i am receiving mv all round.
on Q15N06-42L (the one with the middle pin missing) top pin im receiving 5.6v and bottom pin im receiving 11.89v. i might have popped this mosfet during my last test too... see attached.
I powered the screen separately using a 9v battery and then powered the unit, and noticed lines across the screen, similar to the image below.
