If your PlayStation 4 doesn’t turn on, there are a few things you can do to troubleshoot the issue. First, check to see if there is any power going to the console from the wall. If there isn’t, you may need to replace the power cord. If there is power going to the console from the wall, try turning off all of your devices and then turning on your PlayStation 4 again. If that doesn’t work, you may need to call Sony customer service.
