    Unplug the TV from the AC outlet then let it cool down, then heat up the main board with hair dryer for 2 ~ 3 minutes then power up the TV and see if the picture is OK or not.

        There are two possibilities with problemas that improve with temperatura:

        * electrolitic capacitors, and

        * flex mainly those of the LCD panel.
