I believe your referring to a lens flare...if so, you must smoothly sand the lens with the finest sand paper and then buff it to perfection

Yellow spot is mainly due to lense stain , so clean your lense from inside. it will solve your problem.

I think it helps. let me know.

Welcome to LCD 101, the blue device is dying in the projector. Replace product with dlp brand and it will last a lifetime. good luck

Hello,
Unfortunately the discoloration is caused by the extreme heat generated by the Lamp has burned the LCD optical polarization filter/elements.
The only solution for this is to replace the entire LCD optical assembly.

Sorry for the bad news, :(

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

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

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. !!!

It sounds like it is related to the red filtered glass before the prism inside the projector. When this gets to hot, it will burn a spot on the glass that causes the yellow spot. I have seen in happen on alot of epson 53c projectors. This has a red filter that is easily scratched when it gets too hot. It will actually look burnt.
