The fault is with its main power regulator section circuit itself. Check all the electrolytic capacitors there. Replace them. Replace the main filter capacitor too.

SOURCE: Lines on tv screen

Both sound like bad LCD panels. The following must be answered to confirm this:
Do the lines appear on all inputs/all signal sources?
Can they be seen in the OSD/menu?
If yes to both questions, it is likely that the LCD panel is bad

SOURCE: thin vertical line runs across the top of screen

Hi my name is Roety,
I can help you with your issue ,
 Try the format, aspect buttons on the Box remote, if the line is there on every input and effect the TV menu your panel (screen) is bad.
A new panel would cost as much as a new TV.

SOURCE: Permanent Vertical Line on my Sony Bravia 46 inch LCD TV

What you're describing is usually the result of an improperly seated connector. With the power disconnected, open the tv and locate any connectors between the LCD screen and the driver circuit board. Unplug them, and reconnect it assuring it's properly and firmly seated. Be careful when handling these cables as they tend to be quite fragile... take your time.

SOURCE: 46 inch Sony flat panel lcd has vertical red and

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

Sony FD Trinitron WEGA KV27FS100 horizontal lines across top part of screen


Check and replace all electrolytic capacitors in the vertical output section circuit. There will be 5 or 6 of them to replace. Replace all at one time. The fault you describes here is technically known as 'vertical retrace lines'. Visit the site named 'Electro-help' for more details. Click this link. View it in 'Flip card' option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. It will make search easy. There are more than 990 posts to different brand TVs now. Sometimes, you might get some more details from there.

Green line down left side and geen snow


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.

Vertical lines across my entire screen


My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

Your whole problem my freind is dryed up capacitors. You should go, if you have the technical ability to replace these capacitors, to http://servicemanuals.net, download the schematic diagram, and start replacing the waveshaper capacitors in the vertical drive circuit.
