My dad just bought a 19" Samsung LCD LE19R7 TV for the kitchen. It's the first LCD TV in his house and I don't know much (anything at all really) about LCD TV's, other than the fact that I'm not that big a fan of them. The problem is: Contrast doesn't appear totally sharp I see lines in the picture from time to time Images can be a little fussy Is there something I need to do to help improve the quality of the picture? Or, is that just how LCD TV's are? Please help.
