I have a PS4 (1215 model). It reads discs fine but the eject button on the console doesn’t work ( can use the software menu to eject discs though). I also touched the copper contact inside the console but there’s no response. Any tips on how to fix this?
Check the cable that comes from the eject daughterboard to see if it’s damaged, not plugged in or connectors on either side of the boards damaged. I would link a guide on how to do this but iFixit doesn’t have one specifically for the eject board.
