Hi! first of all, sorry for my bad English xd
i have a dead ps4 controller and i tried to repair it, but i admit that I'm learning almost everything about diagrams o how to "understand" PCBs, I'm absolute noob, but i love this kind of things :) the controller had drift on the right analog, i changed the potentiometer on the left side on the analog, and the drift keeps going, so i thought that maybe when i was disordering, i take off one of the pads of the front side of the PCB, so i tried to "unite" the mid pin of potentiometer with the pad that follow his "vein" and...........as you can see, i screw up really bad xd
after that i tried to use the multimeter to check spots where the right stick comeback to his "zero value" but i screw up again and i don't know what thing touch with the potentiometer but now the controller doesn't even turn on
i know that this doesn't have repair, but i want to know why and how i can check which chip on the motherboard died cause my curiosity? and how can i "read" the veins though the pcb to create my own bridges if someday if have to.
thank you for reading and sharing your knowledge :)
