SOURCE: Thick Black Line on Screen

This is caused by dead pixel sensors. There are hundreds of pixel sensors at the edges of the screen, when they go out it will cause a line varying in size depending on the amount of sensors that go out, and the line can vary in color, red, blue, green, white, and black. Unfortunately, the only fix for this is to replace the screen.

SOURCE: 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
