What's wrong with my new LCD?

give it time to burn in.Maybe it needs a few hours..If not bring it back!!!!

If you are watching a standard def picture it will look like that. How is it with a high def signal. Or a dvd.

check all your cable connections

Yes if you purchased it to watch regular cable then what you are seeing is normal, crap in is very visible on new HIDEF units, great idea to try a DVD and hopefully Hi Def material....do you have digital cable or Direct TV?, Standard analog basic cable stations look like crap on my HDTV,
