Don't feel bad. You didn't do anything wrong.
They sent you a TV with a bad power supply board for the
screen. The TV is trying to power up the screen, but it can't. Because of a defective part somewhere on the power inverter board for the screen. That is why the power/opc light is flashing.
I would call them back and and make them replace the TV.
Power indicator blinking is an indication that the protection circuit inside the unit has been activated to prevent further damage. You may need to have the unit checked by qualified technician. Most probable cause is a damage component in the power supply circuit or those directly connected to it (mostly output component).
