"Do engineers get a giggle from making things frustrating for the rest of us?"
I don't know. Why don't you ask him. He just answered your last question.
Just in case you don't know, there has never been a CRT projector that was ever intended to be installed or serviced by the end user. You had to be factory trained just to install them. A end user couldn't buy one direct. You had to go through a approved dealer who wouldn't sell you one unless they installed it and for good reason.

I think that most people who fix things for a living wonder from time to time what the engineer was thinking. Auto mechanics in particular have a right to this notion.It's just a passing thought though. Truth is I am extremely grateful for the help and patience of those on this forum and I want to say thank you. If you're in the Toronto area sometime I'll buy the beer.

Got 2 Blu-ray discs today, concert discs actually (Nickelback, and AC/DC). When I play them I get 2 pictures overlayed on top of each other about a foot above, (the screen is 9'X5') and the total picture is about 2/3 the size once I get past the disc menu. I tried another couple of DVD's (not Blu-ray) and they still play just fine. I tried putting that little jumper back on and it made no difference except the symptom with rolling came back when I use the old combined player (DVD and VHS) through a scaler. Not a bad picture from the old VHS tapes considering what they are. Since the PJ works fine on other sources I expect it to be with the way the signal is handled before it gets to the PJ.
Once again I'm missing something obvious and hoping one of you has the answer.
Thanks

I can see why even an Ampro would reject Nickelback, but the ACDC should work. Wink

Let me read pasts posts to see what I can come up with..

OK, a few things:

1) Some Ampro 4600s just don't like the Fury, esp at 1080p, and will give image shirt and/or wraparound. Tse said it was something to do with H retrace. I have a 4600 HD here right now from 2000, and it's fine.

2) THose older Ampros will show H shift at any resolution with the Fury1 and 2, that's what I've found anyways.

Now, I am parting out this 4600HD. Tubes are taken, so is the HVPS, but the rest works. Every board from your 4600 will swap to this one, and I'll sell it cheap if you're interested.

3) THe left and right wraparound (if the image is centered) should be cured by the blanking controls, left and right. YOu might lose a bit of the image left and right, but not enough to really affect the image. Sports scores should still be intact, etc.

Check the manual, there are some codes that might help lessen the wraparound, like fast or slow retrace.

The problem appears to be vertical and some of the test patterns do the same thing if I go into help with a Blu-ray playing. The crosshairs show 2 horizontal lines instead of one. The little squares likewise show doubles as if the vertical sweep is starting at 2 different positions.
As far as the parts from the Ampro you are parting out I'm certainly interested in anything that would help.
I suspect that these machines are like most types of equipment when it comes to what's practical for spares: the part one needs is the part that's hard to find because it failed also in other units? Anyway yes I am interested,thanks.
I have a teenage daughter if that answers the Nickelback, I'm more of a Johnny Winter/ Deep Purple kind of guy.

I just checked for some more symptoms n the hope of describing more accurately. Test 3 which should be the same scan frequency as Blu-ray doesn't show a problem. Test 4 with a B-ray disc playing shows 2 of everything. The squares are doubled and adjusting the blanking top or bottom drops 2 lines at a time. This makes me reasonably confidant that the PJ is not the problem.
I hope this helps to surround this problem.
Thanks again

Try setting the player to output 1080I or 720P and see what happens. Will your PC monitor take 1080P? IF so, try connecting the output of the Fury to it and see what happens.
Are you using a version of "BOX" that has IAC or are you trying to set it up without it. I don't remember if your double image is side by side or top and bottom.
If you are just doing BR player>HD Fury>projector, try setting the projectors right static shift to 95 and right phase to 95. Those settings should put the full image on the screen at 1080P 60Hz. Make sure the player is not set to 1080P 24Hz.

If you have the "BOX" with IAC, try turning the centering pot on the box while you are looking at the screen.

Life would be a whole lot easier if you would post some pictures.

OK 24Hz is bad. Turned it off and SOB, the picture is really, really nice.Watched AC/DC live at Donnington; could have lived with a little more blurry picture during "Jail Break" when Angus mooned the crowd but other than that great picture.
Thanks
By the way the beer offer is sincere. Let me know if you're in the Toronto area anytime.

Ok I bought a box 1040 because horizontal shift at max is still nowhere near as far right as I want to go to maximize the screen face. Box 1040 will move the image left and when the little knob IAC is turned all the way to the right the image is where it would be without box 1040. Gamma boost may be a good thing but there are times when this isn't true such as when Angus Young moons the audience.
Any ideas on how to centre the image on the screen of the tube so I can move the projector a little closer to the screen?
Maybe a service manual; there may be an adjustment in the unit?
Thanks

Blu-ray> Fury>A/B switch(optional; same result)>PJ
Thanks

Sorry, I kinda got interrupted for a moment and lost my train of thought.
A/B>1040>PJ
Turning the IAC knob left moves the image left on the screen (predictable) then the image disappears (again predictable)
I thought the idea of the 1040 was to move the image to the right so once again I am missing something obvious.

Are you sure you have your projector setup right? Where do you have the "Phase" control set?
