[AK_Chopra]

I can see a faint line rolling across my lcd screen and it can be seen very clearly on the screen. Especially on white backgrounds, under lights it can be notice very clearly on the lcd screen. I had checked all my cables and ther are working absolutely fine. Can any body tell me that why i'm having such problem on my lcd hdtv? What can i do in order to get rid of the rolling lines across my lcd hdtv? Kindly provide me the solution to resolve the above issue.

I think a cable signal booster would help you out, if part of the problem is in your signal level. If the signal is low coming into the room, then a booster would help the picture to increas its resolution. But if it's boosted too much it can make the picture worse on your screen.

Make sure that you're not crossing the power cords with the componet cables and the same goes for coax cable from the cable company. These cables don't need to touch each other. I hope your using a surge protection with EMI/EMF to cut down on noise or rolls.

According to me i think you need to contact for your manufacturer, in order to resolve your issue. He might be able to help you out to resolve the above issue.
