Thats a pixel data problem, there's no data being sent to that row of pixels so they don't change color. This is a pixel address registry (PAR) issue and the PAR circuits need to be serviced its usually due to open or shorted SMT components on the PAR circuits. PAR also sends data, voltage, and control to each pixel, the green line you see are pixels that have voltage but because there's no data sent too them their all green because there's no control. If the pixels have voltage but no data or control they show up as green red, blue, yellow, or whit line vertically down the LCD panel. The vertical-horizontal section of PAR are controlled by 16 to 32 bit micro-controllers which may need replacing. If its under warranty take it back if not have your local repair center fix the tv for you...

I had this same issue, and solved it by putting the TV in "Theater Mode', which can be acheived by hitting the "Theater" button on the remote.

When the color of the screen is complete green, you should not worry. That is the normal color that should be on the screen when no program is coming in because the cable box is off. So simply press OK on the remote of your digital box and your will see picture on your TV. If none appeared, then there is problem on your cable box. Call then your service provider.
