bought a used TV and the picture is blurry

[geormiet]

I just bought a used Phillips 32" flat screen TV for $300.

I turned it on for a little at the guy's house before buying it, and it seemed ok, a little blurry, but I assumed that it was because it wasn't hooked up to a cable. Because the tv itself looked very new and clean, I assumed the picture would also look fine.

now that I've lugged it home, however, everything is still blurry. I don't have cable, but I plugged my gamecube into it and it is really not acceptable, it's too blurry.

Is there some setting I'm supposed to change? Are phillips TVs always blurry? Was this TV dropped? I'm gonna try to plug in a dvd player, but I haven't yet.

But still, WTF??
