Faint Blue Cloud in the middle of the screen -

You have the "blue blob" problem. This is a failing optic block. $500-1000 to fix. Time for a new TV unfortunately.

Hi Bear,

This is likely an issue with the polarizing plates, which need to be calibrated or replaced. This is not something that can be done by the average user. If your problem persists, please send us a message: Projector Repair Bulb Replacement

The Optical Block / Light Engine is the problem. Very expensive repair / over $1000

how to fix my problem Blue haze/cloud in center of screen, slowly spreading .but last time my lamp broken I order by my self and fixed now I have the blue color in my screen please let me know what is the problem may be I need to replaced same parts please let me know how to fix thank you

if it is an lcd projector, its possible the lamp blew due to fan failure and the lamp getting hot prior to failure may have been enough to burn the lcd's. If it is an lcd projector, that's most likely what has happened

it sound like convergance chips might be the trouble to do it yourself is a big job get quote good luck

Sounds like magnetic interference,Do you have a speaker close to that corner?If so you need to relocate it a little farther away.

BAD LIGHT ENGINE

yes, is the optics unit block, the blue lens have a cloud in the lens

What you see on your screen are retrace lines, it can happen for various reasons. Jut lower the screen voltage by adjusting the knob specified as "screen" on the LOT, this will disappear.
