This is likely a bad logic board but most of the time it indicates a bad LCD panel

I have evenly spaced, rows of two vertical green and red lines from top to bottom of my vizio plasma P50HDTV10A


Somehow when switching between the tv and the dvd my wife encountered the pink and green, thin, parallel, vertical lines on the screen. The picture was visible with the lines. I turned the tv off and on but the problem persisted. Unplugged tv for about two minutes and after plugging it back in and turning it on the vertical lines very gone and the picture was back to normal.

Red and green snow near the sides of the screen


As in there's blotches of red and green at the edges, but the image is still there?
If so, then your screen may have come into contact with magnets, or maybe the alignments are off (TVs align overlapping images in red, green, and blue).
As always, check with the manufacturer support lines, as they would have specific information for these kinds of scenarios.

Red,green and blue lines across screen


I f these lines are slightly diagonal and they all showed up at the same time. you probaly have an open resistor in the ABL circuit. since your set is 13 yrs old, I would not put a penny into it.
You might take the front grill cover off and the panel behind it and find the little black box with 6 little controls 3 are for focus 3 are for screen turn the screen ones ever so slightly counter clock wise. the control in the middle is the green screen adjustment. If the green line goes away try the one labeled r for red and b for blue.

One green vertical line in HDTV Vizio 42


Try changing the H/V position in the TV Set Up menu. You can adjust the horizontal and vertical position of the screen and move it enough that the green line disappears from the screen.

Philips Flat Screen Green Lines


The LCD Panel is defective. You will need to replace the LCD Panel. It will probably be cheaper to replace the monitor since the LCD Panel may exceed the monitor cost.

Single lines of single color (red,green, blue) are LCD panel failures.

1 or 2 lines of single color are LCD Panel failures.

Multple color lines could be anything so in this case you start by checking the power circuit.
