If you are using the component video inputs, check your component video connections. You may have the Pb and Pr connections reversed or not plugged in at all. All three (Y,Pb, and Pr) are needed for it to work right. Also make sure that you have the component cables from the home theatre going to the component inputs on the TV. You can get the manual at the link below if you need it.
