If the line travels from the top of the screen to the bottom, try disconnecting the Tcon LVDS lead. The Tcon is located in the top middle of the LCD rear. Disconnect the LVDS from the Tcon by pushing in the outer lobes. Clean the contacts on the LVDs lead and reinsert. If this doesnt cure the fault, disconnect the ribbons from the Tcon connecting the LCD and clean and reinsert. If this doesnt cure the fault you have a faulty LCD.
If the vertical line doesnt travel from top to bottom of the LCD, the LCD is faulty (LCD matrix buffer).Hope this helps :)

SOURCE: nec plasmasync 4200w 3 vertical lines one yellow two purple

Sorry to tell you, it is not a scratch, but a bad cable connection from the driver IC's, connecting up the plasma screen to the drive board, or the drive IC for that section of the screen is defective. It is not a repair a user can do as there are no user replaceable parts inside this set. Your going to have to call NEC or an experienced Plasma repair shop.

snoopmikeym - Have you found anything out on what is causing the line?? I am completely frustrated with Hitachi no tech help what so ever. The nearest service place is in a town of about 500 people and 30 miles away... I doubt they've worked on a 55" plasma before....

SOURCE: green vertical line on the right side of screen

I bumped my screen by accident recently and now have a similar problem (multiple vertical and horizontal thin lines). I was told that the screen is now bad and probably cannot be repaired. The cost of replacement is more than the cost of a new set. Sorry, but that may not be the answer that you are looking for.

I had that tv less than 2 years. So if you have a warranty and lines get it in fast.

SHARP 70" LC-70UH30U has a blue vertical line on the right side of screen. is it fixable? T-con board? new screen?
It means one vertical output line for vertical pixels for the screen controller is either disconnected or damaged. Most likely the screen needs replacing or the controller itself.

Dell Latitude D505 half of screen is black with colored vertical lines.
Sounds like you have a section of dead pixels. This can happen if the laptop has been dropped a lot or stepped on or some type of impact on the laptop. This is a hardware issue. You will need to have the screen replaced. In my opinion, by the age of the laptop, its better off getting a new one.

Blue vertical line
The lines appearing on your LCD means it has a defect on the screen.

There are 3 types of pixel defect
1) dead pixel - pixel is always off
2) stuck pixel - pixel is always on
3) hot pixel - pixel is on but in red, green, blue or yellow, can also be a light black color

You can try to fix stuck or hot pixels but dead is dead.
1st method, flashing different colors rapidly:
JSScreenfix.com has a great tool. This is their free java applet or you can download it below.

2nd method, applying pressure to pixel:
Damp paper towel, Small stylus or dull pencil.

3rd method, tapping the pixel:
Pen with cover on or another small, blunt object.


If your laptop is still under warranty, get it replaced. If not you are looking at the most expensive part in a laptop to get replaced. (LCD screens on laptop is roughly equivalent to 40-60% of the total laptop cost

Line in my lc screen
A line from top to bottom or side to side is a dead or failed pixel sensor. There are hundreds of pixel sensors at the edges of the screen, when one fails it causes a line, the line can be red, blue, white, or black. Unfortunately, there is no way of repairing the line, other that replacing the screen.

Green vertical line on the right side of screen
Warranty still alive?
Hope so; the problem could be an expensive one.

The screen appearance is controlled by allowing light from a backlight through by turning pixels off and on.
This switching is done by a matrix that turns on vertical and horizontal pixels of the right shade at the right time to produce the image you see.
One of the control elements for the vertical that controls the transmission of green light from the backlight, has died (no longer switching off and on when told) and these are normally a part of the LCD screen assembly itself and not easily replaceable.

I would be talking to Sharp - this shouldn't happen in 6-7 months of use.
