The biggest thing on my own 9500LC with drifting convergence that I put up with for a year turned out to be a loose focus yoke as 'someone' had forgotten to tighten the brass wingnuts on the back. It was on the green tube, and as the set warmed up, the focus yoke shifted very slightly, causing misconvergence.

Also, make sure your memory is in the 'unlocked' mode. If it is in locked, then the Marquee will not save your convergence changes. 'Someone' that I also know had this problem.

Hi,

...and if You're still experiencing noticeable drift after putting all of this good advice into practice, You could maybe live with the following workaround:

- Make a setup for optimum viewing after Power On and save that as a channel number (e.g. No. 1).
- Wait until the PJ is at operating temperature and drift has ceased and make a second setup. Save that as another channel (e.g. No. 2).

So whenever You power up the PJ You just have to select channel 1 and if during viewing the drift becomes really noticeable You just switch to channel 2.
This is how I did it with a Barco that I had before my Marquee and that drifted too (didn't want to fix this then).

More about channels and how to set them up can be found here: http://www.etechvideo.com/techarticle2.htm (lower half of the article).

I thought it over in mind, the steps that I do, and it occurred to me that when everything is almost done, but still in the ringing-zone, I use phase to shift the image out to the right side of the screen, and then bring it back in with shifting green geometry to the left, then red and blue are realigned with the remote also. Maybe I should swivel the green tube to the left at this point and not use the remote. Redo toe-in one more time instead of using the remote here also, just like Justin seems to describing, the second set-up at the very end, sort of. I will try it this way next time.

Apart from lens flapping, i believe Big E is correct, green should be a fixed mount.

The wolf man case and I are right

Heck I have worked on a
Ecp 4100(been in it at least 50 times many times to track down issues)
Nec 10 pg(20 times as I tinkered with the set)
Marquee 8110+(6 times tops for adjustments due to moveing it while I replaced the belly and lvps fans)
Converted it to a 9500lc

Non and I repeat non of the mounting hardware on them allowed for any adjustment for the green

If your referring to lens flapping yes they do but its normally set and never messed with(who knows what kind of mess you could get into with that)

If you don't believe me and case then ask curt he will say the same thing

I'm telling you, I gave green a little smack because I wanted to know what was off, with the pj being in line towards the screen or not. Like you both, I always assumed that green could never be shifted to either side, because of the 2 bolts at he front, assuming it would self-align when green is put back on, which I changed, months and months later I decided to go over the pj aliment towards the screen again, as it looked a little crooked, and found out that green neck board did not match up with the back end of it, so I loosed all tubes and green were realigned. When blue tube is being swapped in some 20 days from now, I'll shot some pictures showing how laser can tell you it can be off. Obviously the other 2 tubes will be off as well doing this.

Post pics or its not true

I know both my Ecp and my nec green tube did NOT pivot as there was no room top or bottom in the mounting hardware(haven't really noticed on my marquees 9 inch tubes but the 8inch ones the green is fixed)

[thewolfman]

[the big E]

Do you have the two screws that hold the sides to the mounting hardware?(if no then I can see that as mine has one with a broke head yet the tubes don't move on they're own)

I do know what my projector looks inside

[thewolfman]

I had a look at it, as my sides are off at the moment, but can't see what you are talking about.

[the big E]

That explains it if you remove the metal panels it will allow all three tubes to move

I had this issue with mine before I went to 9inch tubes(will still do it if you apply enough pressure to the top mounting hardware at the side)

I never removed the side panels when I set mine up either time hence your drifting issue(only removed the top panels)
