A horizontal line that rolls from the bottom to the top of the tv could be a Hum Bar. This is from a bad ground either for the house electric system or for the cable system. By code, these grounds are supposed to be connected (bonded) together. In other words, the electrical interference is going through your tv instead of into the ground. Fuzzy picture is usually from low cable signal. This can be due to bad cables, connections, or splitters or problems outside with the drop (cable line outside that runs to the house). Splitters, by design, lower the cable signal (i.e. a 2 way splitter cuts the signal in half). If you have unnecessary splitters you should remove them. If you have more than about 6 or 7 tvs, you may need to add an amplifier.

SOURCE: samsung lns4051d 40in has horizontal lines across

This sound likes the incoming signal is week. You should play a DVD player to see if the problem stays same or not.
If you try all sources ie HDMI, AV Component, etc...the TV show the same problem. There are two possibilites: T-Con board or main board need replacing. You should need technician to figure out the problem. Hope it help.

I have owned an emerson tv for two years now. All of a sudden the picture has become very blurry and white. It is not the cable connection and a DVD is also white and blurry. Even the input channels are...


you must open the back cover of tv, and then things you should do is set "SCREEN" adjustment on the flyback transformer. you must turn it counterclockwise to reduce and decrease the level of screen brightness. turn screen adjustment gradually until the horizontal blanking lines disappear from the screen. and blurred images will be sharp again
