i will post some pictures and perhaps you can tell me if you think im getting maximum out of the projector and if not what improvements i can do. i do have a little convergence drift as well. should i get some of the hd mods?

First, what model projector do you have? I can tell its a CRT.
Second, its almost hard to tell if its CRT or not until you look to the left of the first image you posted, and you can see that the edge is out of focus compared to the center, and what looks to be a significant enough amount... Unless thats the camera
Otherwise, I'd say you got yourself a nice looking picture, really nice, that a 8 or 9"?

I just checked and you have a 9500. Can you give a full accounting of your set up?
It looks good so far.

GIVE US THE DETAILS OF YOUR SETUP.
Projector
Sources
Screen material and size
how are they connected
So far it looks good.

nice looking picture, grid lines in pic 3 look a little on the fat side inidicating a stock marquee AFAIK tell from the shots posted. Focus can be tightened up, convergence stabilized, and that foggy looking haze removed with servicing /modifications to the circuitry.

hello crt lovers out there! yes it is a 9500lc ultra. ive had it mounted in the celing in my last apartment and was not happy with the picture, many problems with bad astig and lensflapping etc. It was mounted a little skewed. Ive recently moved so im shooting on the floor now and have adjusted the cpc magnets. ive reseted everything to zero a few minuts ago so i can tweak everything from scratch again....
the projector is a 9500lc ultra and the tubes have run about 5500houers. my source is the ps3system. I dont know what else would be a better source right now. is a video scaler cheap? i was also thinkin of getting some of the mods for the machine, what would you recomend at first? my screen is home made and about 2 meters wide. any settings recommended in my playstation? i also use a gamma booster device(cheap one)atatched to the hd fury 1. the biggest reson im doing it all over again is that the convergence are drifting apart a little every time i turn it on and off. Ive red that it could be fixed with the mods to? or if the problem is that ive stressed the remote settings to much instead of centering everything mechanically? i shall try to center the rasters with the focus coils now instead of the remote(green convergence service)
bright 35+gamma x device(makes the picture brighter)
contrast 52

one more thing ive noticed is that the blobs in defocused mode are way smaller on green than the other colors, i dont think green is as sharp as blue and especially red. is this normal? I know that blue should not be sat as sharp for greyscales...

THat explains why the center looks so much much sharper than my NECs! I need to get a 9"!!!!

Make sure when you do convergence the PJ is warmed up for at least 30-45 minutes. One other thing to do after this warm up period is to loosen the LC housings a little . adjust the grids manually if you can. Slightly tapping the lens to move them ever so slightly. then tighten them all down really tight.
Now do your electronic convergence. next time it should be pretty well aligned after a 15-30 minute warm up.
But changing the key Caps and resistors on the rear heat sink boards will lessen the warm up time.
If you can find a cheap Lumagen HDQ or HDP it will be a nice addition to have 11 point greyscale and gamma adjustment.
But overall its looking very very nice.
How are the rubber bellows? make sure they are not leaking or sweating.

thanks for the convergence tips! how is the grids adjusted manually? is it some magnets for it? i've tried to center them with the focus coils, is that wrong way to do it? i have released a little glycol once, about 5months ago or so. how often is it needed?
dragamn: witch one of the mods would you say makes the biggest difference? and what is the price? can it be shipped to sweden?

i know it is a lot of questions here but one more thing, the small dots in the lines are visible at 720p but not at 1080p, does that suggest that it would be better with 720p? and should i be able to se the dots with 1080p?

anything cheap in the video chain will degrade the picture quality and Fury 1 is not a great perfromer by any means. My first suggestion is get the new Moome card, then decide whether to add a video scaler later.

You should zero out convergence first, then center the rasters by loosening the Brass wing nuts on the focus coil and osciallting it like a hoola-hoop. static raster centering isn't done through the Conv. circuit anyway, it's delivered through the sweep coils. My 8500 was drifting all over the place. Even after a full warm up it was always out somewhere and it's why I started offering the mod's. A few nights ago I showed Curt my Convergence from a dead cold start and I think he was impressed. It was 90% converged dead cold and 99% perfect 15 minutes later.

you should be able to see any dots or lines at 1080P easily on a 9500. I have done work for people in the Europe before, shipping is expensive though. check your PM's.

Is this long warm up time a normal thing for the Marqees? Seems abit excessive to have a 45 minute wait til your convergence settles down. My Sony 1001 is abit like that, but not 45 minutes, my NEC seems spot on exactly where i set it right from the get go, no warm up required at all.

Actually, its a digital projector running in CRT mode. It was the last feature the manufacturers could think to come up with in digitals to make them sell. I think next year's CRT mode will expand to mimic different kinds of CRTs, too.

Fina fisken Andreas !
Now i start to miss my marq 8500 being in rest.... just as i've gotten the nec XG setup propperly. That familiar electrohome test-pattern gives me a warm fuzzy feeling
So on to collect parts to get mine into an 9500lc !

no it isn't, PJ should be warmed up/ fully converged in approx. 20 minutes in my opinion. If it takes longer than that then something is off.
It should also be repeatable from one day to the next, requiring only quick touch-ups every few months.

He was asking why his convergence keeps drifting. I was explaining a way to lessen that when first setting up. I said to warm it up for 45 minutes so the metal has time to expand. Also this should be done with the bolts for the lens plates loose. Once this is warmed up then you do a mechanical convergence by moving the lenses. The you tighten it all up really well. Now you do electronic convergence.
next time you start the PJ it should be converged fairly close right off the bat, maybe 7-15 minutes for complete convergence and then it won't drift any more during the movie.
I found in my blend set up I need to tighten up my Mount!!! Each PJ is converged after 3-7 minutes but the center is off in the blend, another 10 minutes gets it right. The Mount itself actually warms up enough to move. I need to fix this but never got around to it. Might not try till i design a venting system above the PJ's, 2 marquees really warm up the room, just ask Jeremy when he stopped by. it gets warm in there!

Sounds far more reasonable. I never made one single adjustment to the 9PG in all the time it was desk mounted, and was pretty amased it never drifted at all, cold, cool, warm, hot, dry or humid, no change. Been on the ceiling about 4 weeks and so far same reliability as above. Im somewhat particular about 100% accurate convergence, if its out anywhere on the screen, ill see it, and then ill keep looking at it til i just have to fix the issue.
