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.

Either bad main logic board or bad lcd panel. If bad panel, it's not worth repair. Can find main board at Encompas Parts.

I get green horizontal lines


Are the green lines on the camera while viewing the picture or is it in the pictures once you have saved them on the computer.

Green Line on your view is you LCD. If the pictures comes out alright then it is just bothersome. Good Luck

Typically this is a convergence problem and can be repair relatively easy. Refer to this video to determine if you truly have a convergence problem. Also make sure you use your TV's original remote to make this adjustment.

Green lines


Due to vertical section failure horizontal line apprears. You did not mention about picture. Green horizontal line means with picture or without picture. With picture means there is some leakage. Without picture only singe horizontal line means vertical section totally not working. Particularly green horizontal line means maybe leads to jungle ic failure. Please mention your simptom clearly what you get and what you will not get both video and audio. It will be helpful to answer. Based on your question this is my small information.
