iPad 6 A1893 backlight issue


iPad 6 / 2018 / A1893.
Problem: Randomly the backlight doesnt come on after pressing power or homebutton. The LCD itself does come on, so the ipad unlocks and whatever.

I've seen this problem before and within warranty apple swaps it as "mainboard issue". I suspect its drop/impact damage.

Nevertheless, this unit is out of warranty, but in mint condition.

Any advices where to begin debugging?...

Filters -> Diode -> Coil

Reference values.
