There is a small white horizontal flicker that appears onscreen. This is temporary and occurs each time the unit is turned on for up to 15mins, then does not happen again until the next time the unit is turned on. Sometimes it does not flicker for days and is fine, sometimes the flicker is there for 15 or 20 mins.

The controller board for the screen is going bad. check shopjimmy.com for replacement parts. It's not a difficult job to do. Once the back of the TV is removed, you'll see it near the center of the screen.
the driver board is bad in the monitor. Has it been in a place that is super hot like in a car? If the verticle driver chip disconnects from the matrix driver array, it will all squish into a single line in the middle of the screen like you are describing.. might try opening and blowing where the driver board connects to the LCD matrix (bunch of connectors on a plastic flat cable/bus connecting to the end of the LCD panel.. heating them could allow them to reconnect.. Its worth a try, right? It has worked for me about 60% time.
If any buffer board is faulty, this kind of fault can occur. Might have a panel fault too. It will be best to contact any service technician, to make it confirm. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic
/ Time slide, can be selected by the drop-down list, at the top left
of the display window, will make surf easy. You can also do a search, by type in the brand name/model
number/IC used, in the search box at the top right of the display window.
I have seen this problem before. It is usually caused by a malfunctioning color wheel. Replacing it should resolve the problem. Let me know if you wish to fix it yourself so that I can find you a replacement.
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....... regards Rocky
It would seem that the video processing section is sensitive to heat. You do not indicate how old the set is, so if under a year, it should still be under warranty and you should request warranty service. Provide as many details about when the problem occurs so that it can be reproduced.
If the unit is out of warranty, check to be sure that any fans on the top or botton are free from dust and are turning. Also, you can open up the back and carefully reseat all of the cables and connectors. A bad connection at one of those could show up like this too. If all of that fails to resolve the problem, then the unit will need to be seen by a servicer. There are no user servicable parts inside other than the actual boards and those are not cheap. It is possible that a servicer may spot something that we can not see, being remote and all..
As long as you only see these artifacts while watching certain broadcasts, the TV is fine. If these lines are present no matter what you are watching, then you have a problem. What you are seeing is signal related and there isn't much you can do to fix that. Think of it like a scratched DVD; you will see strange things on the screen at times and many think it's the TV when it's only the signal from the device to the TV that is corrupt.
I have thought of one possible solution and this will depend on your TV's ability to slightly stretch the picture in vertical/horizontal directions. If your TV will let you, you may be able to raise the top of the picture a cm or so to hide the flickering. Check the TV's onscreen menu for anything to do with picture alignment. This is nothing to do with aspect ratio though so ignore that.
