I've owned my DLP for a few years and just started noticing a line of white discoloration on the screen. It is very faint when you're watching TV but noticeable if a scene has a solid color in it. The discoloring is about 7in long and 2in wide - it almost looks like a shooting star. It is very noticeable when I turn off my set and the screen goes black before it shuts down. Is this a bulb issue? Any help would be appreciated.

1-Reset the TV by unplugging its power cord for 30 seconds and plugging it back in. This is an essential troubleshooting tool as a simple reset often will resolve the great majority of technical issues experienced by any kind of TV. Power the TV on after plugging it back in and check the picture for any improvement.
2-Unscrew the coaxial cable that attaches your wall cable outlet to either the coaxial cable input on the plasma TV or to any digital cable converters you may use at home. Check the copper needle in the middle of the cable for any bending or damage and screw the cable back on the coaxial input. Again, check the picture for any improvements.
3-Secure the audio/video connection cables that attach the source device you are trying to watch to the plasma TV. This is a particularly important step if you use component cables. Component cables separate a video signal into different colors, so a damaged or loose component cable can lead to noticeable discoloration on the screen. Once the cables are secure, both in the source device and the plasma TV, check the picture again to see if this may have resolved the issue.
4-Scan your channel lineup and check the other TVs in your home to determine the scope of the problem. If you see the discoloration only on one or a few channels, and the same channels are discolored on the other TVs in your home, you may be part of a cable service outage and you will need to report the issue to your cable provider. If all the channels on the one TV have the same discoloration, and the other TVs in the home look normal, the plasma TV likely will need to be serviced for a problem with its picture components.
Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens.Ths if your tv is a dlp if its a Lcd it will be an issue with your light engine: Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!
Is your TV LCD or DLP? Encompass Parts shows your model to have Lamp with part number for lamp as A-1606-034-B which then means DLP ,which then it means you may have your light engine going bad which is called optics unit Block part number is

Most definitely! The lamp is a consumer replaceable item and your owners manual should have instructions on how to complete this task. If you don't have your owners manual and more post your model number and i will get you some instructions on how to replace it!
I would suggest to try to get this TV fix while still under warranty. Normally the manufacturers give one year.
In regards to the discoloration, there is not much you do but to let the Sony authorized repair center knows about it so they can fix it. Ask them if their work is guarantee as well for how long.
you have a shorted green CRT that is affecting the other crts the short is internat to the crt that leaves what is called retrace lines. if the set is more than three years old then replace all three guns.
it sounds as if there are speakers to close to the tv or the built in speakers are not magnetically sheilded properly (maufacturer defect) if u have or have ever had speakers on the left and right side of your tv then the magnets in them will discolor and distort the screen. sometimes even long after the speakers have been moved away from the tv it will still look that way. you may try going to the library( or online )and looking in tv repair books on how to build a homade degauser unless your tv has that feature built into it in the menu somewhere like some computer monitors do. I had placed the front speaker of a 5.1 surround sound system on top my tv and it cuased that same problem, but i found out that by placing a small round magnet with a hole in the center on top of the tv (after removing the speaker for good) right where the discoloration was.. had to flip it one side or the other to get proper effect...it immediatly took away most of the discoloration and over time it disappeared. I hope this helps. Please email me at [email protected] as to your conclusion in case it will help others. thanks, Adam
samsung hls4266wx xaa --"off colored" pixels--best I can describe it--lines of them across the entire screen and both sides have strange discolored 'blobs' of the same discoloration. just replaced lamp with expensive Philips lamp, was very careful and the screen is the same. is this a color wheel issue or something else? how do I fix it--or should I take it somewhere and have it looked at? Thank
