I rebuild database, reinstal software, no effect)
Can I have damaged ribbon cable?
Thanks for help 
Bytheway - I cant put bluray disc to drive.
Take the disc drive apart again and make sure it’s closed properly and that everything is aligned inside.
Test the entry point while you have it apart. You should be able to slide a disc in with the cover off.
Cover on*
Be sure the drive is closed properly. Test the arms and be sure they all move freely. Test the rollers movement as well.
Thank you for help, but ribbon cable was damaged. I bought new and disc drive work perfectly
I need help my ps4 won’t read discs
