Hello, I am buying a lcd and found both of these for great deals. The RCA is cheaper, but it's a 1080p vs the Panny being 720p. Both are 60hz. Which one should i get. Thanks in advance.

I have an Olevia HDTV with a built in digital tuner, when I got it, I was able to get some local HD channels, when I reciently went to the HD channels I had , I was unable to view them (blank screen and no sound with a "No Picture" message), I had this problem with all HD and digital channels...
