Hi Stain,
If your TV has a 58 on the screen, it could possibly be a protective film. You would note the film with a blue tab on the corner of the TV. If you do not see a tab, do not try to peel the screen.
If you still see something on your screen, please reach out to us at 1-800-SAMSUNG, 8 AM - 12 AM EST, seven days a week. Our LiveChat agents are also available by clicking on the ‘Support’ link on our website.
