If you’re having trouble reading discs on your PlayStation 4, there may be a few things you can do to help. First, make sure that your PlayStation 4 is properly plugged in and turned on. If it’s not, try turning it off and on again. Second, make sure that your PlayStation 4 is formatted with a valid disc drive. Third, try changing the firmware of your PlayStation 4. Finally, if all of these steps don’t work and you still can’t read discs, you may need to get a new PlayStation 4 or replace the discs altogether.
