Neither. the light filter on the blue lcd panel is fried due to excessive dust and heat. you may need to replace the entire optical engine if you cannot get the individual part.

SOURCE: YELLOW SPOT ON SCREEN

There may be a dust fleck on one of the LCD screens inside your projector. I had a similar problem and managed to clean it. But it requires you to dissassemble the entire projector !!!. If you are not technical, don't do this yourself. !!!

I have a similar issue with yellow pattern on the left and top right of my screen. Took it apart and found the blue lcd had damage that matched the yellow area that was projected. I thought it was the lens but it was the blue lcd .It has gone bad and no replacement. Are you interested in selling the bulb or the whole projector? I have since purchased another projector and am keeping the bad one for spare parts. Hope this helps..Ben

Hi:

The problem here is the one of the miniature LCD screens in the unit is faulty, in this case its the blue one. There are three of them inside the unit RED<GRN<BLUE. The blue seems to be failing in your unit, for instance if you mix red and green you get yellow. Have a local shop service the unit and clean and refocus the unit back to factory spec's..

not sure which model you have but sounds like the blue polarizer has overheated over time. when you put the new lamp in I would think that the extra light you now have is highlighting the problem more plainly.
If this is the case then a new polarizer would be needed

Yellow spot in middle of screen


Hi there,
We have the same exact problem with the same TV. We've only replaced the bulb once about a year ago. Don't know if it had anything to do with the fact that we now have a large yellow circle in the middle of our screen, which is about 7" round.
We only noticed the yellow mark about 4 months ago.
Hopefully someone will have a solution for us that doesn't cost an arm and a leg. Paid $2100 for this set and are a little disappointed.

Having a big yellow spot background in the middle of the picture.


Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine. Have a blessed one!

This is probably the polarizing filter. It will need to be replaced. It should not cost very much to fix.

Yellow spot on Sony 55"


Possible dust in light engine? What ever you do, don't blow it out with the set on or hot. This easily equals instant death to bulb.
