Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

The set is under a year old and is under warranty. The LVDS cable inside these sets have a history of coming loose. The problem could be the panel. Either way, the set is the problem and needs to be looked at. This set is worked on in the home and does not need to be taken to a shop, so, you can still use it. Contact Samsung at: 1-800-SAMSUNG Hope this helps.

Unplug for 30 seconds from it's power source and then try it again. If that doesn't work, call Samsung for further troubleshooting and have your model number and serial number handy. Please be prepared to tell them how long the line is.

I did some reading on this. They said its caused by a faulty DMD board. I understand it's costly... around $700 to replace. Still looking for a cheaper avenue...

Thin horizontal black line on lcd monitor


It sounds like the light has gone out at that point on the screen, you're going to have to replace the LCD monitor itself.

My toshiba laptop has a thick white line down the screen


The normal cause of lines across the LCD of a laptop is a damaged video cable. The unusual cause would be the video card itself.

To determine which item is at fault, you need only attach an external monitor to your laptop's video-out, and then swap your monitor view to 'both' or mirrored (usually just the function key (FN), plus one of the Fkeys...look for an off-blue picture of a monitor on the Fkeys).

If the lines across the screen also appear on an external monitor, then the video card is damaged.

If the lines only appear on the laptop's LCD, but not the external monitor, then just the laptop's internal video cable is damaged.

Hope this helps.

42 inch samsung plasma tv black vertical lines


Hi, Depeending on the thickness of the lines matters. If the lines are Black and about 1-2 inches thick it may be a bad bottom buffer board or a bad panel (screen).
If the lines are thin 1/16 to 1/8 inch it is most likely a bad panel.
You can open up the set and depending on the model, see the thin board/boards running across the bottom with ribbon cables going to the panel. You may be able to attempt reseating the ribbon cables, but be careful as some retainer plugs break very easy.
If the lines are thick black and the reseating doesn't correct it you may be able to buy the coresponding buffer. Unfortunately some bottom buffers are actually part of the panel. If you are not comfortable taking it apart then call a professional but be aware labor charges start around $200 not counting parts, panels start at $600 up to over $1000
hope this helps
Thanks
