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

1 Answer

Pincushion like problem

Had the Light Engine replaced (yellow blotch on whites and 4:3 burnin).
(This is actually the larger TV M52W56LCD)

With the new LE, there is a moderate pincushion effect.

Now vertical lines aren't really vertical. Crosshatch image shows curvature at the top and bottom.

Service tech wasn't any help. He fixed the alignment of the engine, so the picture was correct on the screen.

Could this be an issue with the mirror? It was smudged and cleaned when the light engine was replaced, could it be curved somehow? I don't think so, because the curvature is symmetric.

    This was actually fixed under the Best Buy Protection, so that worked out. The new light engine fixed the color problems.

    The mounting screws for the light engine had to be adjusted (on the second trip) to move the whole picture up and down and "tilt".

    The tech had no idea how to access the service menu, just a board swapper.

    I called the PSP and asked if another company did service in the area under the warranty. I have another appointment with a tech next week.

You did not mention that this cost any money, so I assume that this was a warranty repair. There is the possibility that the new light engine is defective (I see it all the time), or TV needs adjustment via service menu, not mechanical. Call company back or call manufacture to get another company in your area to come out and repair your TV properly. Don't quit until your TV is working properly. Good luck.

The yellow blotching is your blue filter going out in the light engine. You will need to replace the engine, but the cost is so high you would be better off replacing your TV.

Yellow/green blotch appears in light areas

Hi,If there's any discoloration,pixilation or hues on the tv it will be an issue w the light engine's 3 lcd chips.This link explains how the lcd technology works: Basically there's 3 LCD chips that create the colors and picture by blending together all when the light of the lamp goes through them.When they start to melt they will start to show the symptoms.You will need to replace the 3 lcd chips or replace the light engine.Good luck and God bless your house!

55 inch hitachi lcd projection tv has yellow and purple blur near the center of the screen

This, sadly is getting to be a very common problem with all Projection LCD TV's
Colored Blotches on an LCD Projection TV are usually caused by defects or marks on filters or lenses on one of the LCD panels themselves which are all located in the light engine (or optical block) First confirm that the lamp or main lens is not discolored by removing the lamp (unplug set and let cool before removing!) and visually inspecting the lamp itself and the lens that it shines onto. The light engine is an expensive part ($600-$1200) to replace and requires major disassembly. Have a tech confirm-Get an estimate -Be sure to vote/rate me if this helped Thanks!

THE screen on my Zenith m52w56lcd tv is dim, has blue cloudiness and yellow spot in the middle. What is wrong?

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!!!

Yellow streaks on tv screen

I have the same problem with the yellow blotch that keeps growing. I had a certified Panasonic technician look at it. It took him 15 minutes and $96 to tell me that the light engine had failed and it would cost $1800 to fix. I contacted Panasonic and they offered me a plasma at 20% off of their MSRP. It didn't amount to much when I realized I could negotiate for about the same on my own. The TV is 4 years old and I paid $2500 at the time. I doubt i will choose Panasonic again.
