My screen has a vertical line red-yellow-green from (top to bottom) that stays there. How to fix it?


I do not know any setting that makes a vertical line red-yellow-green from (top to bottom)

If you can find a monitor to connect to and know how to tell the PC to send a signal to it (ie, on a Dell it is Function F8) you can determine if it is your Video card or your screen that has failed. The Video card is part of the Motherboard and very challenging to replace. The LCD screen however is not as expensive and relitively easy to replace. You can watch YouTube videos on how to. A screen can be found at sites like Amazon and EBay.

I have yellow lines on my toughbook from top to bottom about 1 inch apart all the way across the screen during start up.Can also see the lines faintly in the background all time.


This would be a symptom of a bad screen. The other possibility is that the video cable might be loose. (It's attached to the back of the screen.) it's a rather thin wire; and at time, may work loose. With a toughbook; due to the costs, and expertise required to work on them, make sure you take it to a shop that has experience. OR, you may end up with further problems

Blue curved line at top of screen and yellow curved line at botto


Do you by chance have any speakers sitting on top of the tv or right beside it. Speakers are unshielded and will cause this effect.

How to fix horisontal lines on display ( see the picture)? They stronger when system is restarted and then fading but never disappearing. They always stay the same.


horizontal lines can be caused by either a faulty grapchics card or a faulty monitor. try adjusting the screen refresh rate. if you are using a windows xp system goto

start>control panel>display>settings>advanced>monitor

then adjust the screen refresh rate and see if the horizontal lines disappear. if not, then you probably have a faulty graphics card or monitor.

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.
