Replacing the blue filter on the Zenith rear projection LCD TV.

Thank you, you've provided the only do-it-yourself advice on how to fix the yellow circle in the middle of my screen without paying a technician as much as it would cost to buy a new one.  If you don't mind I have a few additional questions.  Do you have any suggestions of where I can a blue replacement filter?  And more specifically what I should be asking/looking for?  
Many Thanks!

It sounds like your looking for a CRT (red) the part # is on the CRT and could be puchased through any Zenith (LG) distributer- usually around $300- $500. Google the part # when you get it and you may find a used Picture Tube (CRT)for cheaper.

Better yet watch it till it completely dies and then pitch it! It costs more to replace the light engine than it would to buy a new tv....I will be putting on in the layaway soon!

My zenith lcd tv has lost its blue tint. most


the light polarizer on the blue lcd panel is fried due to excesive dust and heat, and therefore need to be replaced. unfortunately, zenith may not sell individual parts of the optical engine, so you'll have to replace the whole optical engine.

Zenith 44" LCD TV


The yellow spot is due to the BLUE LCD and/or lens assy cracked, reason, to much HEAT! The blue is the darkest color and hold the most heat, so it goes first, always! In some cases it’s only the lens, however most of the time LCD is damage to. Parts are available, however install and alignment is timely. Quick fix is the complete light engine, which for model# E44W46LCD is part# 3141VSN916C, which customer cost is $1,449.27, wholesale for about $1,065.21. Rebuilt, if you can find it around 850.00 to 950.00. However the rebuilt does not always look as good as factory. My advice, TRASH set. This part will fail again in about 3 to 4 years, unless you watch a lot of white video. Remember, on a black or dark picture, all three LCD are blocking 100% of the light, causing extreme heat within the light engine. It’s a bad design.

Yellow circle


The huge yellow circle is either your blue filter is burnt out (very common in Zenith DLP) or you LCD cube is bad. I would bet it is the blue filter. Zeniths DLPs have 3 color filters one blue (a pinkish color), one green (a grayish brown)and one red (it is red). For the bulb indicator I would check and make sure your lamp is seated to the ballast correctly. Just take it out and put it back in.

Yellow haze


Hi...the yellow haze is probably the blue filter is burnt and needs replaced. This is very common in Zeniths. There are 3 color filters in the Zeniths blue (pinkish in color), green (grayish in color) and the red (it is red). The #1 problem in this TV is the blue filter is burnt and it is an easy fix. It could also be the LCD cube is bad. I would try the blue filter replacement first. It will probably do the trick.

Growing blue haze on our picture screen.


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.
