Line faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent. Line faults to all LCD screen are similar, irrespective of its brand and screen size.

This sounds like it is a heat related wiring issue with the screen and the connector to the screen. Best to take this in to an apple genius bar and show them the ipad when the line is present. They should be able to then replace the screen for you.

A vertical line could indicate a faulty lower scan (long skinny boards along the bottom of the set) board, a faulty lower scan connection to the screen or a bad screen altogether!

hi,

check if the line appears in BIOS...dont worry when i say BIOS...not sure how to check...turn the system off...restart the system and keep tapping the F2 key...you would get a Blue screen...check if the lines appear on this screen...if it appears...it could either be b'cause the display driver has gone wrong or the system might have a physical damage.....if the lines does not occur on this screen....it is a manufacturing defect...please contact the manufacturer and report the issue for solution.......

adjust voltage G2 Screen. thats why have retrace line. resolder also CRT board.

If the coloured lines are in the edges, then there is absolutely no problem and it should not be visible from a viewing range of 1.5 meters and further. If the lines are in the middle of the screen, then your phosphor coating (the screen) is burnt. you need to buy a new one, since burnt screens are not repairable.

This is a common problem with LCD screens. It is pixel line damage and the screen is permanently damaged and is not repairable. It will probably get worse. The only answer is to replace it

I have two vertical very thin green lines on TV how do I fix

I've had the same problem. A temporary fix that I have found is to turn up the contrast all the way (press [2nd] then hold down the up arrow) until the screen becomes mostly black. Then turn the contrast back down (press [2nd] then hold down the down arrow) until it is at a normal level. If you can get rid of all the white lines when you turn up the contrast the screen will be back to normal. Unfortunately this does not permanently fix the problem because I cannot get rid of all the lines and it seems to be getting progressively worse each time it start up the calculator.
