The Marquee is already on the ceiling on unistruts. I need help with the following-

1. Raster centering. Will need to remove lenses from the mounted projector. Should have doen this with the projector on the ground. Damn!
2. Aligning flare rings, deflection yokes
3. Aligning projector parallel to screen. Right now it needs to be moved forward as its spilling on the screen. Also this does not have the anamorphic mod- so thats going to be a challenge.
4. Basic convergence- I can always touch it up later.

let me know if you have any experience with Marquees and a ballpark figure on how much it would cost. I will help during the setup process. Looking to get this done as soon as possible- pref this weekend. Its been long without a projector.

Hello

If the tube magnetics are heavily glued, you may want to free them up (chip the glue away) before bringing in help.

If you put somebody else to do the centering & Aligning, you'll miss all the fun Wink

I agree with Dragan on all points.

Turn your projector ON.

Push the HELP button on the remote.

Read.

Yeah, the Marquee has a pretty good onboard tutorial that walks you through it. I also agree with Dragan and Nash, if you haven't touched the magnetics, most likely they are pretty close to optimized already, especially on an old 8000. Greyscale and color is where the work is since your mechanical is already done, IMO.

I went ahead with the setup yesterday. I had the nec 6pg+ before this and the marquee was so much easier. With the NEC, colors were great and so was the panning etc. However I never got the 3D depth and clarity that I would expect from a CRT- the reason was that I never got the convergence quite right. The problem was an improper setup where the projector was not quite square to the screen.

Thats why this time I wanted to it right from the very beginning this time.

Learning 1: Use the mount. Mounting to a unistrut is much more difficult. Chains would have made it easier. However sliding back and forth on the unistrut is much more difficult this way. Esp not being able to adjust the vertical raster size adequately on an unmodified marquee makes it more difficult.

Learning 2: get the projector square as much as possible to the screen. With the NEC its much easier, since I could get the static pattern up, use a mirror to see if the green lines reflects back on the green tube center. The marquee lacks this pattern and you cant use the mirror.

Elaine Benes, I am not George. There are 2 kinds of users on this forum- some very knowledgeable. The other are newbies like myself who are looking for help, sometimes on something very basic. Thanks to Curt's forum and the users here, people like me get a chance to experience CRT. Your reply doesnt help with that.

I now have the projector done with a basic setup. I watched part of '9' yesterday- great movie with colors and low gamma values.Looking good- image seems brighter. White balance looks correct- I need to do the whole setup with e lumagen gamma correction to get it perfect. I'll post pictures once things are looking good.

I should mention that there was a time yesterday when 2 of my friends were struggling to get the projector slid forward, the top cover had slid off, the focus board came loose and was in danger of falling- the hdm board was already on the ground, tht the JVC RS-1 on videogon for 1200 was looking like a great option!

Well, glad you got it up!!!

What Lumagen are you using?

its a great Processor and with it you can use the shrink function for proper raster hight for 1.78 and even 2.35 using active area scanning.

I suggest for Blu ray movies that have 2.4 aspect you go with 800p@48hz or72hz .

Here is a great thread on Active area scanning

Craig Rounds a pro calibrator who is very well respected here and across the world wrote it.
With a lumagen HDP/HDQ and especially the new radiance its very easy to get a great image from the Marquee.

Before i went to the Blend i used the HDQ with 1920x800 @72 Hz. This lowers the bandwidth used and increases smoothness for pans.

In one of the menus there is a shrink function to help get verticle geometry correct if you do not have time to get the anamorphic squeeze done.

But if you want to do the mod , for 1.76 you need to change three resistors on the VDM to 56kohm, for 2.4 you need to change them to 68Kohm.
Id just go with 68Kohm to get maximum adjustability.

PS: you also have a reply on AVS from Mr bob a local calibrator with Marquee experiance.

Drags, i think he means there is no center cross hatch pattern, one where there is a + smack dab in the middle of the screen.

Art, with the marquee its best to show an external full filed or grid pattern from DVE or the free AVS test pattern disc and center the edges and not the center.
It is most likely that Electrohoms geometry controls for linearity work differently that your NEC did. Most Marquee owners juts eyeball a full field pattern at the resolution you plan top use to equal distance on all sides. that is the best method for me.
