I strongly disagree with expert given info.
LG 42LC2D is LCD tv that does not have all those circuit boards that expert is talking about.
Problem sounds with lcd panel that got black lines, lcd panel will be replaced to fix he tv but it would cost you 80% of new tv price.

Across vertically or horizontally... It makes all the dif. It could be 3 boards on the set. The YSUS-main the YBU-upper/YBL-Lower. The Y buffer upper controls the top half of the screen, the Y buffer lower the lower half and the YSUS-main controls those 2 boards. They work in unison, when one goes they all fail. The other possibility is dry solder joints on the the D, G, E, F boards. All you would need to do with that is reheat the solder joints at the ribbon cable conx.

Best Regards and Semper Fi

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: phillips plasma tv MDL 42PF9966 Black Line across screen

The ribbon cable to the drive has either came loose of the drive itself went bad. You can open up the back if you are confident and see if adjusting the cable gets the line back. If not you will need to replace the Upper Y Drive.

Thanks

So I have a 50 Lg ( LG 50LN5700). There is still a picture however about every 3 seconds it goes from regular to blurry and repeats. There seem to be about 3 black lines across the top horizontally about 3...

To clarify, are the 3 black lines horizontal (left to right across entire width of screen)? or are the 3 black lines vertical (top to bottom across entire height of screen)?

Horizontal lines are almost always the result of a failed panel, and no board replacement will fix the issue.

Vertical lines such as you have described (only 3) are probably also a bad panel. If the black lines were evenly spaced in a repeating pattern, it could be a mainboard or TCONN board.

Has this panel been cracked? or perhaps cleaned recently with too much water or cleaning solvent that has gotten the screen wet?

You may have to sell the TV for parts.

Screen keeps going black then grey and white lines start to come across the screen.

This is not the fault with remote control. It is with your TV itself. Contact any service technician.

Black lines across the screen

Black lines across the screen generally means that the pixels on the screen itself have gone bad, or the contacts/processor chip has a broken connection. Either way, its an issue that requires repair.

Black line running horizontally across TV screen

A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.
