If they are thin vertical lines then I'm afraid there is a fault within the plasma screen & this would need replaced which is a very costly repair.

SOURCE: vertical flickering color lines instead of pictures

Soory man there is no deflection yoke or vertical output IC in a plasma TV set.LOL This person has a problem with whats called the substain power supply or bad caoacitors in the main supply. there is also a possibility that the set has a bad tuner. Only performing test on the set will determine the problem.

SOURCE: Colored "snow" vertical line an inch thick on Samsung plasma

That is the sustain and buffer boards. Try to find a repair shop to repair on the component/board level because the cost of new boards out weighs the replacement cost.

How to fix Multi color Vertical Lines on a Vizio E470i-AO TV


Does the menu function display the same lines? What kind of cables are using ? (HDMI, Component vid, S-video, co-ax)
Were you as tenacious checking all cables/connections as you were the electronics? Lets rule out this all too often over-looked possibility.
Do you still get the lines with nothing connected to the TV? (no source connected)

No picture, only colored vertical lines


Settings. It sounds like the convergence. It needs to be adjusted. Have had this problem before. A lot of people actually throw there TVA away because they have this problem and they think its broken, when its usually just a simple fix of adjusting the convergence. You have to make sure the little box, on the convergence settings is in the middle. Hope it fixes ur problem. :)

When switching tv on it shows vertical lines and fades away


This can be an indcation two things 1: a defective focus/screen block or 2: a defective CRT if the lines are of one color then it is that color CRT. in any event you will need to have a tech work on this, doing this repair yourself can be very dangerous for you and the set.

Vertical white line near the left end of the screen.


Usually when there are colored lines on the LCD its because the screen is going bad. Quick way to verify this, try a different monitor on your computer and if the line goes away then you know for sure the monitor is bad.

If you try a different monitor and the line remains then you know that the video card is bad.
