    I also have the yellow spot. The image/spot has a clearly defined and sharp margin, and seems to be some sort of geometric shape (ie - not a round dot). I removed the bult and examined it and it appears to be perfect - no burn in or marks of yellow detected on the lens. I'm suspecting the prism or LCD next but don't know how to examine these...

    I'm an electronics eng. techn by training. I have the same problem. This is not DUST, or a SMUDGE. It is a pixel problem as the problem "speck" is geometric and is exactly in the place of the pixel realestate. It is yellow too. I imagine that this is a defect with the individual transmission via the pixel transister driver. I have taken mine apart and determined that this is in the core of the image driver. It would appear a design flaw and, apparently, common with this model of Sony projector. The only way to fix this with out spending $1,500 (yes, no sh#@!) is to go after Sony as a collective and make big big big NOISE!

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 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

No to your question. The lens is fixed it cannot shift horizontally only although there are projectors that can do this. I am sure you have the front foot retracted? I have had to do the same as you are doing or find a lower table.

Large dot in the middle of the projected display


there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

Sharp notevision xgnv6xu oval yellow spot


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

Yellow area in the projected image


Hello Media Man,

Looks like your projector has done it. Thats acommon trouble to ageing polirising lens, usually the blue. less blue, the green and red make up the yellowish image on the screen. The blue is bombarded with tremendous heat from the lamp and it fade and wash out. If its free, its worth replacing. Get quote for the poliriser; 2 pieces each color.
Good Luck.
