No OTA Guide

[kmaren]

I recently "upgraded" from a Samsung HP-R4272 to a Hitachi P50T501.  With the Samsung I had no issues with the Guide.  With the new Hitachi I cannot find a way for the guide to show the OTA programming.  I only have the HD Antenna.

The HP-R4272 still works great but according to American it has a bad panel.  It has a 2 inch thick black bar that runs horizontal across the screen.  I would hate to discard this TV inappropriatly.  Anyone know what options I have for this TV?
