Ok so on a mini 1 you’ve checked L2200 & D8228. can you check you have continuity from L8225 -> D8228 -> L2200 -> pins 30 & 32 on J2201 FPC ?

Next what is the voltage ? is it just VCC_Main or boosted somewhat ? either way after that i feel your looking at U8100 if all else checks out . Oh and if the voltage is right maybe test a known good lcd

Best of luck
