SOURCE: 40 inch lcd blue line vertical
The display screen is made of a matrix of elements connected to cables
along the side and top. On your unit, some of these many, tiny
connections are making contact intermittantly thus losing the elements
in that area. These contacts are held in place with just pressure and
if that is disturbed, you lose that line of elements. Try squeezing the
cabinet of the TV on the outside at the top in the area of the loss and
see if that makes a difference. May have to go inside and see if the
contact assembly is disturbed or warped or something.
Hope ya fix it!

Horizontal or vertical bars on the screen could be from an ac line interference, adjacent magnetic field, bad input wire connections.....especially HDMI connector cables. A bad HDMI cable causes all kinds of unwanted picture interference. Check the conditon of all connection wires for proper fit and function. Keep in mind the method in which you connect your tv will result how the tv performs. As well this line problem could be a circuit issue too, requiring a technician to look at it.

Hi my name is Roety,
I can help you with your issue ,
If the line is present on all inputs, and shows in the menu then that means the panel is bad, The panel is the front screen section. A new panel would cost more than a new TV

The reason for the green lines are the resolution. I'm assuming you're TV is set at 1080i, not 720p or 1080p correct? What happens is the "i" stands for interlaced, meaning, your TV displays your images with scan-lines. The "p" stands for progressive, meaning, TV displays picture as a whole. You can not visibly see the scan lines when seeing 1080i, but certain TV programs are not outputting their show to the resolution you're at, which will cause you to have the green line up at the top of your TV. SOME TVs might let you adjust the settings to rid yourself of the scanline, but most consumer TVs will not let you without the maintenance code to protect your unit from over calibrating and braking your television. Hope this helps.
