You need to contact Sony on this one. They have had a series of defective light engines in their DLP sets and this is one of those models. They will undoubtedly instruct you to take it to an authorized service center. However, if, as in our area, there is not an authorized servicer they will give a special autorization to a qualified shop as they did in our case. We have seen several of these.

The bad light engine is typically characterized by color blotches and color speckles on the screen. The bad units we have have (not coincidentally, me thinks) have all had problems with the blue.

The customer service line is 1-800-282-2848. Remember that you always catch more flies with honey than you do with vinegar. You are trying to get them to pay for something that they are not under any obligation to. Be firm if necessary, but be kind. They should help you out.

Good luck!

SOURCE: I have blue blotches on my tv screen that gets

I have the same exact TV, with the same problem!
I found out that Zenith has a class action litigation open thru July 2010
Your Optic Light Engine is Defective and Zenith has to replace it for free
Or give you a new 50" Plasma or 44" LCD.
Here is the link with all the details **
Call the service center and let them know what your problem is and that you know
about the litigation. They will have a tech call you and troubleshoot it over the phone.
Then they will order the Light Engine and have a Tech come to your house and
replace it. It will cost you nothing!!!

Hp pavilion dx6 laptop screen. there's blotches on the center of screen, is it the screen itself or something wrong in the video card?

If the blotches never move when you change applications, then the screen is faulty. Screens can be found online and you might be able to find a You Tube video showing you how to change it. Just google replacement laptop screens and you'll find many places to get a new one.

Blue spots on pictures

there is an adjustment that can be done by an authorized tech, this is not something you can do. it is a voltage adjustment that needs to be done . the panel has now come to full conditioning and needs to have changes to the power that drives it. it gets worse because of the higher voltages that are feeding it.

VT45 Projector: Blue pixels throughout screen

If the problem is what I describe as a blue haze over the entire image projected, I was told this is a defect in the cable - we have a Dell Video Projector 2300 - and it takes only a dell VGA cable.

So, the problem is in the cable - solution is replace cable.
