Light Blue Area - Zenith E4446LCD 44

A yellow area usually in the middle of the screen indicates a damaged optical light engine.

You have a bad light engine, very costly repair.

Go to the Zenith repair site. This has been resolved in a lawsuit. Zenith will fix it free of charge through 7/1/2010. The shop just picked my up to replace the light engine free of charge. Call 1-800-228-1757, have your model number and serial number, and where you purchased it. Here's the neat thing-the question I asked is "have they fixed the problem with the light engine, or is it going to keep going bad?" If happens again (blue lines/spots) before 7/1/2010, they'll replace the TV with a new and different TV of equal value!

Me too! Is this a related light engine problem that people are experiencing with the "red cloud" in the middle of the screen? I just replaced the lamp, which I thought was the problem, but nope, the blue is still there. So definitely not the lamp. I don't know what to do?

It could be as simple as dust contamination in the LE or lcd chip. You need a clean room to work on this area of the unit and NOTHING you can do there would make that possible, short of spending a few thousand to build one. Before we added a clean room enviroment we simply pulled the LE and sent it in to PTS - who has one and reinstalled...
In your case take it to a qualified shop and you'll save yourself a lot of grief..

Optics block or "light engine".. lots of $$. LCD filters have warped due to clogging of intake air filter resulting in overheating. The area in question is nicknamed "the cube" and is actually NLA for some brands.

me too ...any ideas?
