This tv has the dreaded blue blob along bottom, right side and a huge light haze in center. If light engine problem do you have possible solution?

Merci

thats a problem with the light engine.

im not saying this is the one that you have, but this is only so you can have an idea.


The main problem is with the LCD panels, with time this panels they wear off, they start losing color and they start doing this blobs/distortions on the pictures.



How to fix it, you have to buy the light engine ._.
At the moment i dont know other way to replace the LCD panels other than buying the light engine.

The light engine in your Sony LCD projection TV works with three color chips (red, green and blue). Inside the light engine the beam of light passes through several filters separating the beam into three and then the mirrors redirect them into each color chip, then all three gather at the prism which sends the picture into the screen

Here you'll see the schematic of the LCD light engine: http://www.oerlikon.com/ecomaXL/index.p ... _projector

Through time the heat of the beam will start to ware off the chips until they get burn marks causing colored blobs, blotches, blue haze or stationary scribble in the screen
