It means that your PlayStation 4 is in “safe mode.” This is a special mode that helps protect your console from damage and helps you troubleshoot problems. Safe mode can help you fix problems with your console, such as the inability to play games or the inability to connect to the internet. If safe mode is not working, you can try using the following steps to troubleshoot your PlayStation 4:

  1. Disconnect all power sources to your PlayStation 4.
  2. Reset your PlayStation 4 by pressing and holding down both power buttons for about 10 seconds.
  3. Try playing some games or using the internet if safe mode is not working.
