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, Green convergence lines are wavy


Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Pictures goes to distorded wavy lines.


This could be attributed to tuning reception of your tv. If your using antenna only, it is most probable. If cable, check your line.

If this is a crt type, moving that tv with that size could somehow bend its circuit board. Loose connection is a probability. Could be some minor component is detached from solder. This can be attributed to tuner and vertical IC.

Just for an input.

Video distortion


You need to take your tv in and have the picture deflector re-aligned.  This doesn't cost much, My dad had to do that to his a few months ago and it cost 30 bucks.

My screen turns green and then turns off


you need to adjust the screen voltage. behind the front grille and inside cover. a small black box 6 adjusters protruding from it. only adjust the the color counterclockwise that matches the problem in this case it's the green so look for the knob with "G" marked by it. there are 2 with "g" marked by them the row across the top of the box are for focus don't adjust. back the knob off untill the raster is blank with your input set to an inactive input, the picture should be blank and black.
when it is you have the adjuster close to where it should be, now change the input to an active signal and turn the color off so that you wil have black and white picture. adjust that knob untill you do have a truely black and white picture not too green or red or blue. go back to inactive video input and check that there are no lines of any color on the screen. repeat if needed. always adjust these knobs slowly the set will be watching you ! if your autofocus won't work now you have the adjustment set too low. check this function before putting back together again. these adjustments can be real touchy so be patient

Wavy lines


Are the wavy lines horizontal or vertical? If they are horizontal and up near the top of the screen it could be 60HZ interference from a power cord running over the cable from the DVD player to the TV. There could also an internal breakdown of the shielding by the power supply of the DVD player. If the lines are vertical it is likely the cable or maybe the input jack on the TV. Could be a number of things.
