So I recently got my ps4 fixed (power connector came off the motherboard) I got it back and it was working fine for a day. Today it suddenly turned off and it isn’t coming back on. I’m thinking the re-solder job done on the connector wasn’t done well. In addition when it was perviously taken in for the fix, one of the thermal pads was lost, the worker said that it could be replaced by a simple piece of plastic, could this also be the cause of a potential overheating? I don’t think it’s the power supply since it was working fine for 4 years, it just wouldn’t make sense for that to be the root of it.
Most computers and game consoles these days have a safety that will cause them to shut down in the event of overheating. If your PS4 shut down as of it was overheated, the thermal pads can possibly be the reason.
