Hi I got two 755 pcbs which got damaged by a faulty head (...yeah i'm stupid)

everything works fine except there is 1 of 12 nozzle block missing. both pcbs are missing different blocks...so i highly assume due to his everything else is fine in the machine (all nozzles can be printed with the same head and carriage is good)

i got a circuit wiring diagram for the 700 series (which also use same printhead, pf3 but basically pf4)

anyone know which smd (fuse/resistor/ic) is affected when overheat from head happens?

thx a lot
