I recently purchased a lg 42ld400 a few wks ago and can't seem to get the picture clear when I saw it n the store it was clear and bright with excellent color while few of my channels are good most look a lil fuzzy or snowy. I have my settings like the one in the store but it dosent look near as good. Maybe half as good. Can you help me with a good pic setup/settings. And another ? If the backlight is set real high can this reduce the life of your lcd and if the picture is set to vivid does this reduce the life.

Yes tou are right about having just comcast cable but I traded my box for a hd box and I viewed the hd channels compared to the same channel in regular and they look no different maybe I need something to actually bring the signal idk. Of have the same tv the same settings and the same cables so I'm note quite understanding the snowy fuzzy look Yes tou are right about having just comcast cable but I traded my box for a hd box and I viewed the hd channels compared to the same channel in regular and they look no different maybe I need something to actually bring the signal idk.
