Question about Zenith E44W46LCD 44" Rear Projection HDTV-Ready Television

1 Answer

Growing blue haze on our picture screen.

We need to know how this is repaired. Apparently, many owners of this model of the Zenith projection TVs are reporting this problem...some more than once. We want to know how long the repairs take. Does the TV have to be taken out of our home to be repaired?

Any information would be most appreciated. We just want to understand the problem and the repair process before we contact our Best Buy warranty people...it's always better to have an idea of what the process will be.

Thank you.

    We have a growing blue haze coming up from the bottom of our screen. What can we do to get this repaired? Is it more cost effective to repair it or is replacing the set a better way to go?

    I have the same problem, there is a blue band at the bottom of the screen. I have removed the back filter and cleaned it on a regular basis, I was unaware of a bottom filter, my owner's manual doesn't mention that. Also, my remote control will stop working after the set warms up. I believe this is a problem with the receiver on the set, not the remote. I have changed its batteries, the indicator lights on the remote work, I can can "see" the IR transmitter flashing by viewing it through a digital camera. The TV is 3 years old and the factory warranty is long gone. Is it possible to get a replacement chassis/module to repair this, or do I just toss the entire TV in the trash?

    continuously blue area to right side of screen--growing over time

  • up north Mar 01, 2008

    I have a growing blue haze on the bottom of my screen.

    I located a replacement light engine from matelectronics.com. This is referenced with a part # 3141VSN180H.

    However, they won't tell me if this actually fits the Zenith E44W46LCD. Also, is this a reasonably simple installation or does it require special training or tools?

    Any advice I can get on this will be greatly appreciated.

This is a bad problem with the light engine caused by overheating usually due to reduced airflow from dirty air filters.
My recommendation is to push your warranty company to replace this subpar model with a different one. There are too many instances of repaired models having a reoccurance of this same problem.

The blue line you are seeing is a product of one or two possibilities. The LCD panel which provides the blue imagery, which by the way is made by SONY Electronics, is defective. The LCD panel, in the optic engine (made by Ricoh) is basically loosing partial horizontal data, or the blue color filter has overheated and is becoming discolored, causing the loss of correct deflection through the optic prism. There are two ways to approach this. LG can offer some concessions and get you squared away, or provide the part, and you would be responsible for the service labor involved. Either way it can happen. The first thing I have to suggest to anyone purchasing a LCD or DLP projection TV is REMEMBER to keep an eye on the air intake filters. LG / Zenith products have one in the rear of the set, and 1 on the bottom of the unit. Reduced air flow through these units cause these "video deflection" issues. Overheating plainly affects these sets. I personally wouldn't own one, no matter who made it.

My panasonic rear projeciton ty 5448911 has a blue ghost. Is the just the bulb?


People who bought rear-projection TVs between 2003 and 2007are bound to find their sets failing with blue, green or yellow blotches,hazing or bands disturbing the picture. It is often called the 'blue haze'problem. This LCD projection blue haze problem is coming from a faulty partknown as the optical block which is expensive to replace, and since Sony hasnot re-engineered the part, will only be replaced with another defective LCDprojection part that will last only between 1 - 4 years, depending on usage. Asit appears Sony produced these expensive TVs knowing about the defect, theyfinally have to reckon with the thousands of customers involved. If you own aSony rear-projection television, here are some steps you can take when the LCDprojection blue haze problem becomes apparent on your TV.
Instructions 1. * 1 Getinformed. Be aware that Sony just extended the warranty of all 2007 rear-viewprojections models (enacted at the end of October 2009) -- just like theprevious years -- so all models now have extensions. Also be aware that theyare not notifying the owners of these extensions even if owners have registeredtheir purchases.There is a lot of information now circulating about how torecognize blue haze problems and the background of how the problem came about. * 2 ContactSony directly about your LCD projection problem. Sony Customer Information Service Center (toll-freetelephone support) is 1.800.222.7669. The SonyCustomer InformationService Center("Priority Service") in Floridais 239.768.7547. * 3 Expect to be told you will need to haveyour set evaluated by a Sony-Authorized service center. Be aware that even ifyou have your optical block placed replaced and the service charge refunded, itwill only be a temporary fix until the replacement burns out again. * 4 Considerif other offers are right for you. Sony may offer you a discount on a new TV intheir "Special Consideration Program". (They stopped makingrear-projection televisions in 2007, but are now producing other flat paneledLCDs and other formats.) Make sure the offer is worth your while by pricing outother sources for buying TVs on sale or discounted before jumping at thisoffer. * 5 If you arenot satisfied with Sony's Customer Relations offers, you can appeal to theirExecutive Review Committee. * 6 If stilldissatisfied with offers regarding blue haze problem on your Sonyrear-projection TV, you can contact the Better Business Bureau. * 7 You canalso take the legal approach. If all else fails, you can file a civil lawsuitsuch as small claims or have a lawyer initiate a class action suit. * 8 There area number of resources with detailed information about how to handle the LCDprojection blue haze problem. Please check the Resources below.
