I purchased a new Sanyo 42″ LCD HDTV. The picture is a bit fuzzy. It is not horrible, but not what I expected. Some time ago I purchased a VISIO 42″ LC HDTV, and it’s picture was wonderful. (Unfortunatley the TV imploded within 2 days). So I did not understand why the picure on the Sanyo would not be as good. I called my Cable provider on Satruday and they told me I needed to by a HD Box from them (for an extra $60 a year). Why did I not need on with the other TV? Also, do some TV’s come with and some without something called a digital tuner? Does that make a difference? Can I get this HD Box from some other source other than my cable company? Is there a better solution? Thank you.
