Blue cloud on screen

I have a growing blue cloud on a Hitachi LCD Rear Projection Television.  How can I fix this?  Is it the bulb or something else?

    I had the 'light Engine" replaced on my set under the manufactures warranty because the picture had deteriorated (6 months old). The day before the service call, the "less than 50 % bulb light came on. After the light engine was replaced ( Approx $2000), there was a small yellow spot in the center, approx1.5" x 1.5". A year has passed and the spot is now 8" x 8" and yesterday the picture turned all red and green; It looks like it would if you turned the red and green tints both up all the way.

Optics block or "light engine".. lots of $$. LCD filters have warped due to clogging of intake air filter resulting in overheating. The area in question is nicknamed "the cube" and is actually NLA for some brands.

Hitachi Television Yellowing on the screen


Suggest you call Hitachi and complain. There is an issue with all projection LCD tvs (not just Hitachi) was that the light engine assembly did not have enough vents for cooling. This translates in a green or yellow blob that starts small and grows larger because the LCD screen frame starts to deform with the heat. Guess they did not test with young kids in the house and the tv on more than it is off :-). In March I managed to get Hitachi to pay for the part and I paid for the labor to get this fixed (out of warranty). The new light engine supposedly is better at cooling though I do see a faint 1/4 inch band of green at the bottom of the screen. Blackburn Electronics in Anderson IN has fixed many of these in the Indianapolis area.

I finally emailed Hitachi about the blue haze and since my televison is only 16 months old they agreed to pay for the part (they didn't say what part) and I will have to pay the service charge. The repairman is coming out on 2 Apr 08. I will post results after that.
