That seems to be a H-linearity issue then.

Any screenshots where the 919 is in action ?

I'll post pictures soon. Found out that some of distortion of red and blue reported earlier were due to temperature problems.
After putting a ventilator on top of the boards unit (split pack) blowing the hot air away and allowing cool fresh air in, all stayed stable.
1080p@60 is the first finished resolution what would "you" suggest to convergence more?
1080p@72 ?
etc.

[ElTopo]

800p@72Hz or 96Hz
817p@72Hz or 96Hz
720p@120Hz for 3D as it is of interest ?

I will have to have a read through this thread abit later on.

Id be interested to know if you get the same flickering lines and shimmering i get on my CineMAX.

[CasetheCorvetteman]

I ran the CRT Run In for about 2 hours last night, and i must say the tubes squeal and buzz alot less now...

Tanks ElTopo will setup these ratio's.

@Case: I would say stop comparing it with a Nec. Start looking at it individual, because even all P19LUG's are not the same. One tube isn't the other. The CineMax or Cine9 as the 909 - 919 are definitely very high end projectors and should preform flawless, but it needs attention.
I must also read trough all service bulletins to see if all modifications are done. Take your time and take it step by step, at the end you'll have a marvelous machine which beats all your previous owned projectors blows you away and tweaked by yourself. How cool is that? It's not plug and play but that's the charm of CRT.
Sometimes it's simple, like the shimmering lines was caused due to overheating, 33 celsius in a small attic made the pj too hot. A € 15,- fan placed on top of pj and a open window was the solution

If you need all service bulletins and board specifications please let me know I'll be happy to send them by email. Just shoot me a PM.

Francisco, I know the 909 is the holy grail of the CRT, but I feel the 909 owners here sitting on clouds sometimes. Case is the first, who dared to highlight the technical weaknesses of the 909, and I think it's good, and helpful for other who doesn't have a 909 (or its derivate). While the 909 probably a very good projector, but hardly can say it beats every other brand/type in every aspect. The NEC XG also a highly advanced machine regarding the electronics, it just have (unfortunately) smaller tubes than the "big ones". But it could be more stable, more reliable (I'm not saying it IS, but COULD) You say all LUGs are individuals, the other tubes aren't?

[CasetheCorvetteman]

Its all true Gabór, the image quality blows the XG away, but its all for nothing if its not perfect, and as it is, its not perfect.

If it wasnt for that, it would be the machine i always dreamed it would be for the past 12 years since i first read about it. Everything said about it in that review made me know then i had to have one, and now that i do, im extremely happy that i made it, but the journey is not complete.

I never knew anything of the NEC projectors prior to my time here, but given my time with them and others, i still believe they are probably the best built machines not only for their time for each model, but for their exceptional quailty, near perfect engineering and flawless convergence system, resulting in stability so good you almost never have to touch it. If the XG was able to be had with P19LUG tubes, i have little doubt that stock for stock, the XG would be unbeatable. It allready is in the 8" relm.

Francisco, ive had the CineMAX running on 1920x1080p for the past 2 hours, its reporting 31°c, and it does the same things when its first turned on. Voltages are reported a fair way off their ratings, no idea if that is common or not, but everything i have noted as irregular about this machine is listed on the Eisemann mods site, so its not just me or my machine that suffer from this.

I sould would love to see it perfected

Startup temp should be about 20 degrees depends on your temp in your room of course.

[CasetheCorvetteman]

Startup temp is always the same as room temp here, after 10 minutes its at about 25-27°c depending on the weather, after 20 minutes it never climbs any more.

[ElTopo]

I only use the pre-set resolutions inside the Lumagen VP these are working perfect.

[Francisco]

Pictures ! note that it still needs tweaking, I'm not finished yet!

[ElTopo]

Nice.

What screen width do you have ?

[CasetheCorvetteman]

Are you seeing that flicker on tge bright scenes too? Or is it something else i see in that folder pic?

[stridsvognen]

I never seen anyone post 1080P 72hz 1:1 pixelresolution pattern from a Barco before, would be nice to see how it handle that when you finish tweaking.

[CasetheCorvetteman]

I am not sure youll a stock machine to do it...
