Hitachi projector model CP X260 projects yellow spot on screen

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?

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

Can I network Shinco printer s2145

with one of these
Only thing is I did not find windows 8 drivers for this printer as standard so you may run into trouble with computers running windows 8 as each computer has to have the exact operating system printer driver designed for its exact operating system .
Unless you can find windows 8 drivers somewhere on the internet
