2-3 times a day I have to rescan my TV and I get some common channels when I scan but 70% are different - I do not move my antenna during these rescans- in fact sometimes I can't get local stations (I'm in N. Central FL) but do get stations in Charleston S.C. and Tampa

This television would benefit from an hdtv indoor outdoor amplified antenna not obstructed by trees, aluminum, bricks, and etc. Make sure the signal type is air and not cable and complete a channel scan during primetime tv hours after connecting to this antenna. Buy a large one that you can mount to the wall usually in a large flat box on the shelf in the store. Philips has one sold at Walmart.
