The TCON board or the LCD panel is faulty. Can confirm by replacing the TCON board.

IMPORTANT: Horizontal lines on the screen are virtually NEVER caused by a bad T-con board. Horizontal lines indicate a defective LCD panel (screen). Check ribbon connectors coming from screen and the T-con board first but likely the Panel.

Fixed non moving lines usually means you have a problem in the panel display or t-con. If it is in warranty get it to a factory authorized service center. If not you can try to change the t-con and see if this fixes the problem, if not then it will be the panel it's self and will be cost prohibitive to repair.

SOURCE: A horizontal thin black line has appeared across screen.

hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

SOURCE: 42" AWA LED LCD TV,

HI:
This maybe due to a faulty T-Con board, this is what I would replace first, since this is the mose inexpensive part in the set, if this does not solve you problem then it is possible that your panel is odefective and needs replacing, if so then it is cheaper to buy a new television.

SOURCE: samsung 32" LED TV Purple Line Horizontally across top of screen

Can you please change the input device to some other you know, works? If you do not notice any problem there, look for the aerial cable going close to any power line or has interference from some other transmissions of any kind nearby.

My led samsung tv has a horizontal line and the upper right corner shows a white vertical lines


Not good. You may have a tab failure. A repair shop may be able to diagnose and repair this, but most likely the lcd panel is broken. The panel is the most expensive part of flat tv's. A new panel will cost more than a used tv.
