In my opinion is not LCD, but the probeme is in line "PP_LCM_BL_ANODE". Try to make jumper or change the LCD-connector (J4200)

lol 10/10 solution 100% workin xD

ok srsly what about FL4211 and FL4291?
check current sinks FL4212/FL4213/FL4292/FL4293, continuity to IC and so
if its only top right then probably current sink is disconnected
