REFERENCE Samsung A11 aka SM-A115F touch not working FIXED

[-=GinZ=-]

Samsung A11 touch not working, during mother board inspection all part is clear, malinis na malinis but sinabi nang customer na nalaglag dw at bigla nawala yung touch, i also try to test in a brandnew LCD but still touch won't work.
STEPS:
check diode mode reading and i found out na walang reading yung TP_INT_N line from cpu to FPC and to make the story short binakbak ko na agad yung CPU then jumper papuntang FPC at d nman nabigo

CPU removal and installation guide using Quick 861DW:
Removal: Heat - 380° Air 60
Installation: Heat 380° Air 35
Reballing Paste - 158° mid temp



DONE
