What are those horizontal lines?

I just bought my first HDTV, a Winbook 32". I plugged the coax from the cable input to see how it looks. The first thing that I noticed is that some SD channels display with alternating lighter and darker lines. The lines are very narrow (maybe the thickness of a pencil) horizontal lines. This only seems to be happening on a couple of channels. Can anyone tell me what causes this? Can I make them go away?


Everything else looks pretty good, and content from the new DVD player looks great.

I bought one of these for xmas at MicroCenter in Dallas for $600 after rebates. I've really enjoyed it so far, but some little things are bothering me, hence I just subscribed and started searching here.


Overall the picture is great (for me not being too much of a connesseur of tvs). And of course you can't beat the value for $600.


But I've noticed that the four corners of the viewable screen are lighter than the rest of the screen...i.e. a quarter circle about an inch in radius, diminishing towards the middle of the screen.


Also the top 2 inches going across seem lighter as well, again fading towards the middle of the screen.


These effects are noticeable when viewing a dark image or when you have the columns on the sides due to standard programming. They really aren't noticeable when viewing a lighter image.


So I'm researching what this effect might be and whether I should look into returning my tv. Any info from anyone is appreciated.
