I havent had any issues with mine apart from the quad. Twice. Although this one is working perfectly well.

Ive got abit over 6,500 hours from July 2001. Tubes look really nice til you turn the set on... Green and blue have static burn in of a Katy Appleton DVD menu, that wouldve had to be there a very long time to get like it is. Ive got a new set of tubes i will get to installing sometime soon.

How many CineMax/Cine9 have been sold worldwide ?

I am still trying to get a clear picture of what is improved in the Cine 9 with respect to the 1209/809. I see that the electromagnetic focus is a clear improvement with 6 poles to get a smaller spotsize.
Also there are more convergence zones in the software?

But the astig is the same 6 pole magnet as the 809.

Also the video out board has much higher bandwith.

Did I forget something? Seems to me that if you mod the video out board (Eisemann) the differences might not be so big?

A lot of things has changed with the design of BR909 chassis (CineMax/Cine 9).
To spare myself a lot of typo, here two technical documents from Barco about the "digitalization" of the chassis.

Ok, a lot has changed. Among others the waveforms are generated digital much more precise. Hmmmm.

Ok she gets more and more beautiful but I have a stupid setup question. The green line is lower than red and blue. Does this mean that she is not hanging under 10,5 degrees (I mean frame horizontal)? I checked with a leveler tool (waterpas) and that seemed ok. All convergence are on 50 and I can't correct with max convergence.

It looks like your skew is not well matched with the green, blue, and red. You should set your skew to zero and then rotate the deflection magnetics until green is plumb to the horizon. Then match red and blue to green by rotating their deflection magnets. After that, use the skew adjustments to touch up red and blue. Then use the skew adjustments to match and straighten the vertical.

Also, is it possible that your scheimpflug on any or all of the tubes is way out of adjustment. Scheimpflug will move the image up, down, left, and right. If it's too far out than you may not be able to correct it with electronic controls.

ps I haven't read your thread so sorry if I mentioned something that was already covered.

You have to center the rasters on tubeface on all three tubes., if you find a perfectly centered raster projecting to the wrong part of the screen then you have to accomodate the projector alignment (or move the screen Razz

)

When I set all controls on 50 I see blue and red making a symmetric curve but green is going from top left to lower right getting more and more lower than the other two.

I noticed that the focus coil, the astig magnet and the deflection coil does not change that and because red and blue are symmetric it seems that the projector is hanging right with respect to the screen.

Looking into the tubes green might be a little higher as raster but perfectly centered. Hard to tell. I can shift the raster relative but that is not more than I can shift with the convergence and max is not enough.

Have to check sheimpflug tomorrow raster shift could not explain that green is not level with red and blue I guess?

As Gjaky says, first while everything is on 49 align all rasters on tube face the same. They need to be on same place on tube face and size. Use trimpots to adjust this first. remember try to minimize electronically adjustments much as possible.

To get red and blue images centered you first need to get them very close, do most of the setup, then they will need moving again with raster shift and you will need to reaim the tubes. As you adjust the red and blue to suit the green, you will be dragging their image towards one edge of the tube face.

Centering height wise on the tube face is a good place to start, but no reason you cant raster shift red and blue to line up with green.

Green looks good to me. Red and Blue need to be aligned vertically with the trimpots of the vertical board.

Had this on my Cine9 too.

Correct, keep electronic adjustments at minimum.

Ok this one is confirmed. First turn on the projector and than the source. That makes sense.

On to the scheimpflug. The manual says to losen two screws on the top. The sticker says to losen screws on the front. How confusing Smile

Hope this will be my only problem today Wink

Top screws are actualy the excentrics that will fine-tune the scheimpflug but they are locked with the front screws.
So first unlock ( don't take them out ) the front screws, get your scheimpflug as good as it gets with the top screws and secure back with front screws.

No where near perfect yet but I don't have to be she is very forgiving. My God this picture is alive and deep! Very much better then all the digital I ever had. So glad I made the switch. Optical is not sharp at the bottom yet, geometrie is rough, convergence too. But all these pictures are so beautiful. One shot from 'continuum' and I am behind with that series Smile

Looked at a part of Gravity and man that is a complete different movie. With no doubt this is the image I am looking for.
On the negative side I find the MAX noisy and I wonder if stretching the electronics to far made her more noisy? The temperature was 28 to 29 degrees. I did not correct the raster enough with the potmeters and had to do a lot of convergence correction (max).

Seems also that under the MAX there is more noise than in front.

I am considering my split pack mod again. I know there is a risk but if I can't get the noise down on other ways I might lengthen the cables and use the split pack front housing. After all I know what can go wrong now with these wires and connectors. Still I prefer not to of cause.
