Re: red line across bottom, green across top

Technical support. Sounds like either a LCD Panel inside set or a bad video processing board. Keep me posted. GURU JAY

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.

My Sony KDF-E50A10 has a Blue glow in the lower bottom middle that is about an inch or two high. It gets bigger than smaller and changes shape. The shape is irregular but always in the middle bottom. ...

This is a Optical Block problem and I am glad Sony is working out a deal for you. The cost of replacing the optical block would be too expensive to consider. It will only get worse as it is used.
A lamp issue would never give you a discoloration in a certain area of the screen. The picture would just be dark or no picture at all. It would even shut down if the lamp was shattered in most cases.

I hope this helps,

Many different small color vertical lines all across the screen

It could have a bad Q-Box. It could cause both problems. The Optical Block also has the ability to cause it too. I would call a service professional to be sure due to the cost of the parts.
Hope this helps,

No blue color, green replaced blue, white is yellow/green


If the set is hooked up using Component cables (red, green, blue), then check to make sure the cables are hooked up correctly, and not defective (change them out). If the color problem remains, then the problem may be in the Optics block of the television (which is not unheard of in this unit).

If the menu of the TV displays blotchy discoloration, and the discoloring is the same for every input on the tv (stationary), then it is the Optics, and the optics need to be changed. It is not the easiest job in the world, and the block itself is quite expensive, although the unit my be under an extended warranty from Sony. Contact them directly to see if you can get any help (cost or service-wise). Hope this helps...

Multi colored vertical lines

Probably you need an optical block, but it would take a tech looking at it to be sure

Red and Green Lines in TV

The optics block has failed and it will have to be replaced. Contact Sony for an auth. service center in your area as the optics block in this unit has a 2 year mnfg. warranty.

Red, horizontal color bar along bottom of screen

This is a failure within the optics block. The optics block will have to be replaced. Contact Sony and complain and they will most likely refer you to an auth. service center and I know they will work with you on the cost of repair. I have had experience with Sony paying from 100% to 75% for this repair.
