Optical block is the culprit! replacement is not too difficult. About the only special tool required is a long phillips screwdriver to reach the screws securing the block to the front panel of the set. Then, there are three connectors on the C board which is part of the block, one connector on the left side of the C board, one fan connector on the left side and then two connectors on the lamp driver board which is on the back of the optical block. Two recessed screws hold the block to the front panel and sometimes there is a third recessed screw to the left of where the lamp is located. Then the block slides out. Reverse the procedure to install the block.

MY PT-AE700U LCD PROJECTOR HAS A BLUE HAZE RUNNING VERTICALLY ON THE LEFT HALF OF THE PICTURE.


Open the upper cover remove screw back side of the projector
Remove LCD connector and clean with soft cloth and fix it again.
close the upper cover and then POWER ON if the problem exist then the blue LCD is faulty and need to be replaced.
(very carefully because the ribbon cables and connector of the LCD is very senstive)

I replaced the lamp on a Panasonic PT-LC80U thinking this will solve the yellow appereance, but it did work, it seems that there are not blues in the image. What Can I Do to solve the problem?


here are some probable causes..
This appears to be an older model (over 5 years old) and LCD projectors turn yellow with age. It's just what they do
However, if you are projecting a computer signal or a component signal, a short in the blue signal of the cable can cast yellow hues over your image. The hue will cover the entire image as if you are viewing the image "through rose (or in this case, lemon) colored glasses" so to speak. That's an easy fix.

Harder fixes: the blue LCD panel is weaking and/or gone bad.

If you have a round yellowish spot in the middle of your screen, the diffuser has been overheated and is "burnt".

Permanent blue hue down one side of screen PT ae700 panasonic replaced lamp made no differance tried compressed air no change please help


if the discoloration has a sharp pixelated edge, it may be the lcd panel. if the edge blends, it's the light filter (polarizer) that is burnt from excessive heat and dust. either one needs replacing.

Panasonic PT-52LCX15- Have a Blue hue along bottom and on part of screen, replaced bulb 2 times, same and used a philips and now panasonic bulb and housings. Any suggestions? Projector? Time to call...


This is a 2005 model; it sounds like you have a burnt optical light engine: part number is

TZSC03047 Part is about 800 dollars and requires tech approval from Panasonic to buy. A number of these optical engines use an elaborate system of lens---the heat from the lamp can damage the lens and the color that is damaged separates enough inside to cause the blue streak somewhere on the screen. I hope you have an extended warranty on this set.

I do this here for free so if this has helped you give me a vote here.

PT-L735 U projectors. Green screen and stretched


The green is the result of the blue device failing. Happens about 4000 hours or so. LCDs can't handle the heat. Check the scaling of the image of the second projector. 16x9 vs 4x3.

good luck
