I work for a auth LG service center and each time I have had this symptom we had to either change what called the T_CON control board or the Plasma display panel itself. You need to cocntact LG @ 800-253-0000 report your problem and they will find a service center in your area you should have 1 year warranty parts and labor.

SOURCE: LG flat panel plasma with red line

I had the same problem and fixed it by replacing the control board. It's a little nerve wracking, but required only simple hand tools. If you'd like to see detailed pictures of the repair check out my blog.

SOURCE: purple line down middle of screen

I could do with a digital photo to be sure, however it sounds like the LCD panel itself has failed.

SOURCE: my Lcd tv has a thin green line running from top

Unfortunately this is a problem with the screen & the only solution is to have it replaced. If it is still under warranty then there should not be any problem if however it is not, then it would be uneconomical to get the screen replaced as this can be very expensive.

Lg 42LD450 center line in the middle

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

There is a blue line down the middle of my sharp lcd 32sb24u tv.

Hello; If this line is razor thin and goes fully from top to bottom, the LCD Panel is bad and costs more than a new TV. Time to shop for a new set if this is the case or just put up with the line. John
