You noted that you had a modem, but do you have a wireless or wired router?
We just got the following equipment and we're trying to figure out how to connect the Internet to the tv for Netflix viewing. We have broadband service through a modem and Blue Ray. Here are the model #s:
Blue Ray 5.1 Channel theater system model HTBD3252 and the TV is a Samsung 530. Any help would be greatly appreciated!
