Think about this way, You opened the Tv but the screen was damage next day the Technician comes for installation, You tell him what happened. What if he refuses to acknowledge that the Tv was damaged in shipping and blames you for damaging it. This way Amazon "MAY" and I say "MAY" refuse to give replacement and ask you to contact TCL for further assistance.
Technician comes opens the Box the Tv is damaged he himself will report that the Tv was damaged and Amazon will issue replacement immediately without any issues.
