My problem is an overall yellow, not just a particular part of the picture. At first I thought it was just the director using yellow or sepia filters during filming for artistic effect. However, after seeing the same movie in a different venue, I see it is just my projector. I hope you are right about the new bulb helping the problem. Thanks for the information on your findings so far.

I cleaned the prism and that brightened the picture but didnt fix the yellow tinge. The bulb is a OEM Phillips with 1038 hours.

Also the picture flickered at first but I set it to high and the flicker stopped. My question is can the bulb cause the yellow tinge or maybe something more serious?

Thanks for any help.
My guess is the panels are starting to get a little crispy due to heat and age.

Regarding yellowing images...

Older LCD projectors would have this problem when the projectors were run in high power mode. I think the higher heat levels would discolor the LCD panels. We have a lot of older Sony LCD projectors at work and the image all turn yellow over time because we run always them in high power mode. The ones in light controlled rooms and run in low power modes seem to be lasting longer.

I have an old RS-1 and I have never used the high power mode. So far (knock on wood) the image looks fine. I have over 3,000 hours and am on my fourth lamp. I was real lucky. The image is sharp in all areas and I do not have any vignetting (darkened corners).

A little hint for others. If your lamp starts to flicker, remove the lamp and clean the contacts on the lamp assembly and the projector. This will usually fix the problem. But always change the bulb when recommended. You do not want to have a bulb explode in the projector. This is rare but it does happen.

If it's not a BIG screen, it's not a theater...

@Todd68 you are not alone...
I have a JVC HD1 (the european twin of the RS1)
I have changed two week agon the bulb with a new Osram P-VIP200/1.0 P21.5
I have bought a new colorimeter X-Rite i1 Pro because my old Eye One Display II gave me wrong result..
I learn how to autocalibrate with my laptop and ArgyllCMS+MadVR...
The result in HCFR are in the following pictures....
In 7 years i have never had such a beautiful image..
This are the result of the ArgyllCMS software testing 493 points in the RGB colour space..
average dE = 0,52
Max dE= 2,59

I think too that the problem of your JVC RS1 is in the lens...
Hope you can fix it soon...
