If you are using an analogue signal then check things like DECT phones, Wifi / DSL modems, power cables, power convertors / UPS, washing machines, dryers, microwaves etc are kept as far away from the cables as possible.
Have you bought anything new recently, when it happens think what things are turned on... is it the garage door being opened etc.
If you are using a digital signal (and ideally something like a DVD player or a games console rather than a cable TV box) then check the HDMI cable. If all appears well then it could well be a fault with the television, especially if you get interference from multiple source (i.e. cable TV, DVD player, console etc)

We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.
