If the lines are there all of the time as in all of the time (TV, DVD, PC, etc), then the TV might have a damaged panel (likely), a bad LCD controller (not likely), or a bad LVDS cable (the internal cable that connects the panel to the controller).

If you're good with electronics, testing/replacing the LVDS cable is usually quite easy, especially on smaller TVs. However, permanent lines on LCD TVs/monitors are usually caused by damaged panels.

What cause the panel to go bad? The TV is just about one year old.

"does it cost a lot to replace the panel?"
For TVs larger than 19", it can be quite expensive to replace the panel. It would be more cost-effective to buy a new TV if the panel is damaged.

"What cause the panel to go bad?"
I once repaired a small TV that was hit by a power surge. The surge caused nearly a hundred rows of pixels to go bad. Luckily, it was some off-brand 19" unit that used a fairly common Toshiba panel. Found a working panel for $60.

Excessive heat, dropping the TV, escaping Wiimotes, etc. can also cause the panel to go bad. Or maybe it was a poorly manufactured LCD to begin with.
