Picked up PS4 today, stuck in safe mode and not powering up by console switch. Unable to get out of safe mode, so thought proceed to solder new switch on as you do. But looks like someone has tried fixing it, with an angle grinder. I’m good with soldering, and repairing boards, but I have no idea where to start with this one. I’m not overly familiar with the ps4, and I’m not sure where I can go from here. Where do the tracks start that lead to the pads under the microswitch? Any help would be really appreciated.
