If you look through the lenses when the projector is running you should see the source of the ghost image. Yes you can wear sunglasses or just turn down contrast and brightness. Is the problem seen on all tubes ?

I don't think there's a leak, the set came from me, and I'm paranoid about glycol leaks. I may not have filled the tube enough, as I flushed the glycol on the tube.

You may get away with taking the lens off, and putting a piece of electrical tape over the air bubble at the top of tube (look into the lens first to see where the bubble/reflection is located. that won't affect your image otherwise as the air bubble is far away from the actual image.

Thats good news. Knowing the Glycol was flushed makes a lot of sense why it might be a tad low.

Are you saying the ghost image is on all three tubes when looking through the lenses ?

It's clearly in all 3 tubes. You can see red and blue in the picture, but at the overlap it's white, not magenta. And Wayne's pic shows a bubble in green.

The people in this forum are AWESOME. Thumbs Up

The response has been fantastic and it worked!

I no longer have the strange prism-like colors projecting beneath my screen. Mr. Green

Thankyou VERY MUCH to EVERYONE who contributed to solving this problem.

I will buy some glycol and top it up the next time I take the projector down.
However, the workaround of masking off the non-image area, where the bubbles are, has eliminated the wayward lights.

I used very thin plastic black electrical tape. By keeping it on the glass and off the rim on the tube, I don't think it filled the small air gap between the tube and the lens. The only problem was the curvature of the tube. Putting on the tape was a trial and error effort and each time I removed the tape, I left a little adhesive behind that I had to wipe off with water and a cotton towel. The other problem was that I did not know how much to mask. It took three tries to get it right. That involved taking the lens off, cutting the tape and installing the tape. Putting the lens back on and running the test pattern again to see if it worked. I did NOT even have to do a re-convergence. Laughing

It was easy to see the bubble with the lens off, by tapping the side of the projector to wiggle the fluid level.
It is the bowl-shaped object above the upper black line.

The bubble is clearly visible on the tube

The first attempt at masking the bubble

The second attempt made the tape a little bigger

This one seems big enough

For comparison, here are the three tape mask sizes

With the final size of tape masking the the upper portion of the tubes, I no longer see any colors below the screen.

I will summarize this and add it to my Marquee 9500LC Ultra Installation Experiences thread:

Now I am inspired to try and do something about that irritating standby noise. Wink

Thanks again everyone.

Nicely done! Smile

No worries running the set like that.

Unplug it, or turn off the switch.

They should change that design...it's nuts.

Your not leaving that machine in standby for more than an hour at a time are you? Surprised

The standby button does not turn off the machine, it leaves it active and ready to use, only without a picture displayed. Standby will wear down your tubes/ electronics. Always use the power button to turn off the 9500. The fan will run even when the machine is turned off with the power button that is normal.

To make it less noisy see here:

Looking out for a fellow Marquee owner. Very Happy

GOZER has Tim's fan mods. It was done by Tim about 4-5 years ago, when the previous owner bought it from Tim. So I guess they hold up fine. Very quite too.

Way to go, Wayne!

Also, I was really sick of what I'd been working on at work, so I took one of Wayne's MOV files and made a 1-second animated GIF of his glycol sloshing around...

FYI, the filesize limit on animated GIFs is 500k. So, I dropped down to 320x240 and 128 colors and came in at 496KB. Wink

Here's a Flash version of Wayne's video of the sloshing glycol. Something is wrong with the linkage because the controls don't show up for some reason - they come from an external file.

Yes, I'm EXTREMELY sick of what I've been working on at work. After working for weeks on the same heinous project, I like a little project that only takes 5 or 10 minutes. Wink
