hello guys, got this phone with hang sometimes so i disassemble it and brush away dust particle inside it. also it was hard drop in the past and the motor got sorted with the ground so i remove the capacitor that connects with the motor to prevent short circuit. re-assembled it back and then backlit stop working. have already replace coil, backlit IC but not solve. LED tracks are ok. also already flash with v9.55 but still no backlit. i need help urgently.
