LG TV

I had an LG 42pc3D that LG had Circuit City replace. They poeple atCircuitCity gave me a 42lc5d. First of all I was told the LCD would be better in my bright living room but it seems to have a film over it when my over head light is on.

The picture quality is terrible. On HD channels it looks amazing but when playing a DVD or most regular channels the faces look almost fake. It looks more like claymation. You can see the color separation. This is a brand new televison and I have not adjusted any of the special settings but I don't want to make it worse. Both Circuit City and LG seem to have no suggestions.

My husband is deployed and I am not all that electronic savy so where should I start to make this TV look better.
