I realize this is an old thread.. but just in case, here are some probable causes..
If you are projecting a computer signal, a short in the blue signal of the VGA cable can cast yellow hues over your image. The hue will cover the entire image as if you are viewing the image "through rose (or in this case, lemon) colored glasses" so to speak.
Or, similarly the blue LCD panel is weaking and/or gone bad.

If you have a round yellowish spot in the middle of your screen, the diffuser has been overheated and is "burnt".

My screen is yellow with grainy lines. I replaced the bulb (after only 776 hours), but the problem persists even with the new bulb. Is there another part inside that may need replacing instead?


The organic polarizers can get burnt by the bright light after a long time. The blue one is most susceptible and results in a yellowing of the projected image.
You can see if it's damaged when the optics unit is dismantled.

The image on screen is almost a dirty yellow colour and not sharp at all. Also where do I purchase new filters from?


Hi,
A yellowing image, especially if it's circular in shape indicates the BLUE LCD polarizer is burned from overheating or just a lot of hours on it & it needs to be replaced to make the yellow go away. You can purchase a new filter from hundreds of online retailers. Just do a search on Google for "NEC VT595 Filter"
REPAIRS:
If you're interested I do replace the polarizer filter panels. I have parts in stock for the NEC VT595. The repair quote is $50 & if you have it repaired the $50 is put toward the repair. The repair will include cleaning all the LCD panels, filters, lenses, etc. on the inside which will bring back the original sharp picture again. If you like you can email me at prmhelp@earthlink.net for more information on having it repaired.
Thank You,

NEC VT 480, replaced new lamp ,still low brightness.


if you remove the lamp, inside the lamp housing you will see a refraction (fly-eye) lens. these evenly distribute the lamp light. the one on the other side from the one you see (there are always 2 lenses) is probably burnt and needs replacing (a common problem with lcd projectors). you will have to send it in to nec. in many of their projectors, both lenses are in one assembly.

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

NEC Model VT48 - need to clean filter


This is a solution for the VT 480 by NEC for filter clean. on the left side there are two slots that have dust filters which can slide vertically to reveal micro screens that one can blow, tap vigorously, or vacuum to remove any dust build up. I hope this helps you with your unit.

My picture brightness is uneven - there is a persistant bright field on my screen.


I have the exact same problem with my AE700. It a started about the same time, around 2500 hours for me. I lived with it untill I could afford a new bulb which arrived yesterday. The old bulb was still working at a 3603 hours when I installed the new one. But the new bulb didn't fix the problem for me either. I may try to take it apart this weekend and give it a good cleaning. Andy
