Pink And Green Lcd Tv Screen Green And Pink Lines On LG LCD TV?

Green and Pink lines on LG LCD TV? - pink and green lcd tv screen

I bought a LCD 37 "LG TV on heavy traffic. I've had about a week. Its been a great exception, a problem. It was this delicate green and pink horizontal lines appear on the screen and are extremely low. I HD with manual override it connected. The lines of HD-hand switch, it is even worse. When I direct to the TV cable box HD is better, but sometimes appear. appears only when the screen is clear and red colors on the screen. erased almost be tempted, but they are there. Is there anything I can do to solve this problem or do not get a lemon?
