I did a little research, and that particular TV set IS HDTV capable, but does NOT have a digital HDTV tuner of it's own. You will need a digital HDTV tuner, not one of the cheap converters, if you want to see HD television over-the-air from that TV set. What you will need to do is to find an HDTV tuner (eBay has a lot of them) and connect it to the componetn video connections on the back of your TV set. These component inputs are red, blue, and green in color, and will aslo require stereo AUDIO cables (RED and WHITE) to completethe installation, for a total of FIVE cables from the set-top box to the TV set.
You will connect the antenna lead to antenna connector on the set-top box, NOT the TV set. If you also have a surround sound system, the set-top box will have a digital audio connector that will feed that signal to the receiver, either an optical (fiber-optic) or a coaxial (using regular RCA audio connectors between the set-top box and the receiver)
Once the antenna is connected to the set-top box and the TV set, go into the MENU of the set-top box, and have the tuner SEARCH for channels. You should be able to see the process unfold on the TV screen if you have selected the right inputson your TV set. Once the tuner has finished scanning, your digital TV channels should be available for viewing.
