Samsung HP-T4254 infrared/remote not working

I have had my HDTV programmed into my A/V receivers remote for quite some time and it worked great for a while. Now, it hardly ever works at all, only rarely. I just got a new Logitech Harmony One Remote and that didnt work for the TV either, though it worked for everything else. I tired to the remote that came with the TV and no luck either. So I am kind of perplexed as I have never had a problem with the IR going out on a TV. I tried unplugging for a minute and that plugging back in and no luck. I tried finding a firmware update, but it said I had the same version on my TV, so apparently there is no update at all.

I am going to call Samsung tomorrow and ask them what is up. Seems kind of ridiculous that something as trivial as that would go out, but whatever.

If anyone has had a problem with this in the past and has any advice, that would be much appreciated. I swear, the more tech I get in to, the more problems I have...
