Do the lines only appear on the Cable box input? It maybe be a problem with your cable. Try to isolate the problem.

Do you see the lines on all sources such as your DVD player as well? If you press the MENU button on the Sharp remote, do the lines go through the menu as well? If yes, it is most likely a TV problem.

A bunch of lines sounds like it is most likely a problem with the connection with the LVDS cable, if not that, then a defective main board.

There isn't really much you can do about it now.
Since the TV is less than a year old, I suggest calling Sharp to locate a local authorized service center.

You need to change your TV's settings and enhancements. Directly from the store and out of the box, the settings are adjusted for easiest sell in the store. That means that:
Your contrast is cranked to 100. Move this down to 50 to 60.
Your brightness may also be cranked up high. Lower it to a level nearer the middle range but not so dark as to lose detail in the shadows.
Your TV is set on "Dynamic" or "Vivid" mode. Pick "natural" or "normal" or standard.
Your sharpness is at least on, if not cranked up. Turn sharpness down or off, and the same with "Edge Enhancement" and "VSM", all to off.

Lastly, I bet you upgraded size and you are now sitting too close to the TV. Roughly, if you are sitting closer than 130 inches (about 11 foot) you might do some rearranging or save some money and get a smaller TV.

Hi,

I got the chat , but some how it got disconnected.
But i would like to help you in this aspect.
HDMI stands for High Definition Multimedia Interface, and supports transmission of both audio and video in high fidelity.

First make sure these things,

Both your computer and your TV will need to support HDMI interface.
It's quite a recent thing in PC graphics cards, so you may have to resort to S-Video, DVI or VGA for the video, plus a 3.5mm stereo cable (or the optical TOSLINK equivalent) for the sound.

Let know your comments and i will follow up with the suggestions.
Thanx for using fixya,
Good luck.
