Projector started projecting a yellow image like someone took a yellow high-liter and drew a big spot on the projection screen. I thought this was a light bulb issue but after installing a new bulb the yellow image is still reflected. Does anyone know the cause/fix for this?
Thanks!
This is probably the polarizing filter. It will need to be replaced. It should not cost very much to fix.
The Purple dots indicate the filters are clogged and let dust get into the optics. You will have to Blow out the prisim block with compressed air and carefully wipe the dust particles off the LCD panels. WHATEVER you do DO not remove the three LCD panels from the block they are a royal pain to line up They can be cleaned with out removing them. If you have a yellow spot on the screen it usually means the blue LCD screen needs to be replaced. this is a more difficult job. The MOST important thing about LCD projectors is to keep the filters cleaned or they overheat spit dust and cook the panels!!
good luck Bohanna

Blue blotches on screen due to dust get optics cleaned should then work ok...yellow spot more likely to be lcd or lens burn a much more serious and expensive problem
The blue blotches you describe are happening on mine too,they look like someone has got a paintbrush and flicked the tip at my screen and got little blue dots all over,but they're in a square formation,only in the middle of my screen,the edges are fine,is this the optics do you think and how easy is it to clean them?,thank you for your help if you answer my question,even if you dont,.. thanks for reading anyway..Dave

Is that hard and worthy to replace the blue polarizor?
