How to fix blurry pictures on samsung 52 in lcd tv

I bought a samsung LN52A650A:14: lcd tv after seeing lots of positive feedback on the forum. However, I cannot fix the blurry pictures. I have Dish satellite service of 200 channels, however, no HDTV service? Can someone help, please?
Thanks.

I know this is very blunt, but in order to get the sharpness of HD, well, you need an HD source

How does a DVD look? Even a regular DVD should look pretty darn nice, assuning ou use component video.

It is a waste having something like this without a HD source, though. No telling what the quality of your satellite signal is on an SD channel.

This will sound weird but.......

Make sure your sat box and TV are both set to standard def. 4:3. Watching standard def. in 1080p settings can sometimes cause problems.

I have AT&T Uverse for cable/HD and if I watch a standard def channel when the Cable Box is set to 1080p, the picture can sometimes not be very good at all. Switching to Standard Def. 4:3 fixes the problem.

BTW, I have a Samsung 52" 1080p LCD.
