Gentlemen,
let me say thanks in advance for the depth and the breath of what I have already learned from all the postings on this site. what a wealth of knowledge. Yes I'm guilty, I did it, I am now a proud, I guess you would have to say, owner of an electrohome marquee 9500lc. this projector has a manufacture date of july 1999. at purchase it had a tube hour usage of under 2000. I think I did OK. no significant burn in that I could tell based on what was indicated in the CRT/ Primer sections. not a ultra as I had hoped but thats Ok, so far.
Too my question, If those of you would be so kind. Not sure as to what I should expect but things are not so perfect. for instance, I can not see any changes when I move the slidebar of the "color, tint or detail" buttons. this can't be normal! any tips as to witch board may need some expert attention?

Those two bars (+ tint) only have effect when you use the multistandard decoder board for input (composite, s-video). The RGBHV inputs cannot be modified in this way, you have to tweak your source for more color etc.

In other words it's supposed to work like that, so don't worry about it. Those controls are intended for broadcast signals (like NTSC or PAL) that arrive with a lot of signal degradation. The inputs you'll give your 9500LC (DVD, BluRay, HDTV) won't suffer from those problems and won't need any color/tint/etc tweaking.

On the other hand the projector itself needs some color tweaking, and not anything that you can do with electronics. The phosphors themselves aren't quite the right color -- that's a characteristic of the phosphors used. You can make them "almost perfect" with some type of color filtering. On an LC projector that means using a tinted C-element. Unfortunately those are nearly unobtanium these days.

You might want to try an experiment. I tried using colored gels (sheets of colored film), applied to the tube face of my 8500. It made an ENORMOUS difference in the color vibrancy and beauty -- see this post.

Unfortunately the tube face is very close to the focal plane of the phosphor, and the gels aren't optically perfect, so they caused a bit of filminess/distortion in the image. The colors were SO much better that I would have kept them anyway if I didn't have a better option, but I ended up getting some tinted HD145 lenses.

You could try getting some of the gels -- they're cheep -- and attaching them to the FRONTS of your lenses. That's far in front of the focal plane and minor optical imperfections shouldn't hurt much. Hell, you can stick a couple of fingers in front of your lens and hardly notice it. Unfortunately it might scatter light and wreck your ANSI contrast, negating the advantage of the LC design, but it's worth a try. The difference in colors is HUGE.

Dont forget to check for sweaty bellows.

And Congrats on a great Unit!!! Your going to love it!!!

Thanks for your replies, I found that info in the service menus after digin alittle, so I guess I kinda wasted one, next time I hope it'll be one worth asking! Color gels sounds like a cool idea. Sounds like a meter or two might be needed, any sugestions?

you don't put Gels in a Luquid coupled optics system. you change the C-elements and you should already have a green tinted one.
