The signal you were sending it was 480i 60hz right? Not 576i 50hz? Look at page 01/03.

If it is 480i 60hz, then it thinks 60hz is 50hz.

I think it has a bad oscillator board. There is a pot you can tweak BTW on the OSC board....but once you have, you need a frequency counter to set it properly again. But as a last gasp you could tweak it till it locks and reports the correct frequencies. If you do it for your standard resolution it might be good enough.

But ONLY do this if you are resigned to buying a new OSC board, and can GET ONE!

As far as the memories go, to me it looks like someone has moved some of the standard ones down to position 07-10. The rest are user created, and useless.

All the RGB-XX ones in the 50s are just the ones it creates when someone hits save for a signal that hasn't had a memory created properly (I don't like the way XGs do this, Xtras just won't save, which is MUCH SAFER IMO).

I'd delete everything but 7-10, and anything named PAL or NTSC, for safety.

Mark, I'm not sure what that DVD player is sending. It's like one of the first Sony progressive scan players that came out and has been relegated to the guest bedroom but brought out for testing the XG recently. I assumed that through the S-Video connection it would be sending 480i at best and I know of no other user adjustable settings in it for resolution, refresh, etc. I'm inclined to go for an oscillator board as you say because I can get one of those for about a third what the system board would cost me. If I can find one then I will try the pot adjustment on my current board first just to see what happens and if it gets buggered then I will have the spare to start over with. Doug told me not to delete anything but without a viewable picture at all, I'm not really concerned with retaining a white balance or other settings. If I can just get back to a stable image at 1080i then I would be more than willing to put in the time for setup.

Well, it's not a PAL dvd is it?

You're playing a NTSC dvd?

My take is, if you don't delete any lines AT ALL, you'll have to PAY to get it fixed one way or the other, whether its sending the boards to a professional, or buying replacements.
If you DO delete some memories, clean it up and maybe restore its functionality, you've saved having to PAY anything to get it working.
If you DO delete memories and it STILL won't work, then you haven't put yourself in any bigger hole, you've just got to PAY to get it working like if you did NOTHING.
See what I'm saying ?
I'd do what Mark suggested, as there is some anecdotal proof, from at least one other user(jarsaneau, one page back) that this is a way to fix this problem.
Personally, I'd jump in with both feet and delete everything with the TRAN in front of it, as they seem to be obviously from the use of the DWIN Transcanner line multiplyer, and are obviously not factory memories, in addition to the ones suggested by Mark.

I agree with Elaine Benes' strategy to erase the SIGNAL ENTRIES to clear them out. I think that's your best shot and if it doesn't work, you are no worse off. I'm not so sure that the OSC board is necessarily out of adjustment. It could be simply the closest match the pj found to use. Also, consider that the name of the signal entry is simply the name given by the individual who made it.

Here's another wild idea. Try running with your scan plugs back the way they were when it ran OK (floor setting) and change the menu setting to FLOOR FRONT. Since you had no problems running that way before, it would prove that the switch to ceiling mode is what got the pj to act weird. It could be that the entries that you have were created for Floor and are just enough off for ceiling to cause the problem. If things look stable again, it would seem that the problem is less likely the pj hardware and more likely that the signal entries are just off for running on the ceiling and you would want to delete them.

Jerry, Drop,
Your S video is running 50 Hz and not what the default is (says 59 Hz in the default area)

There is no NTSC entry on the video input but there is one for S video

Default says 33 kHz, this could be the entry that says DVD BUT that is on the component input.

Im thinking the projector was selecting the component input when it saw 1080I.

Some suggestions.

Confirm the disc is NTSC 60Hz and use the composite video input. Make a signal entry and phase it. Put this at the top of the list for diagnostics.

Run a 480P signal and see if it hits on a entry line, if it does you might try to change the default to 480P for now. Check the info menu to make sure it says sep for separate sync and not comp.

From there and confirming the 1080I signal runs from the temporary entry for now dont store to default area. Do not store anything to default until it runs out with no problems. Take some of the strain off it by phasing each new entry (see the S video picture, no phase has been done)

Thanks everyone for the suggestions today. I will be trying again this evening. Doug, I will have to pick up a BNC to RCA adapter from Ratshack on the way home so I can use the composite video input. Not a bad thing to have anyway probably. I think I recall my 9PG+ having one on it before I sold it, should have pulled that one off.

Stupid RadioShack! I always go in there thinking, "they will have that" and then I get there and they NEVER have it. They were totally out of the BNC to RCA adapters, at least at the location I went to last night. Oh well, there is one near the office here that I will try at lunch time. I did try a different DVD in my old player last night just to confirm that I was using an NTSC disc. It finally synced to that same line #12 PAL line and still shows 50hz as Doug noted.

Even if it hits a PAL memory for an NTSC signal, it still should show 15khz, 60hz in the INFO screen.

That is the oscillator readout, not a list of what the memory is built on.

That is why I think the oscillator is playing funny buggers.

Well, I thought I had something tonight. Not. I got the S-Video feed from my old DVD player to be seen as a new signal and it showed 60Hz instead of the 50Hz it's been showing. It showed up as NTSC Cinema. I ran the signal for over 10 minutes, did phase, stored. I then stored this to the default data area, block 1 as prompted on screen. The movie played while unconverged it was watchable. I tried switching away from the input and coming back and it locked on fine. I then turned on my 1080i source and got the usual flashing in and out picture which eventually locked on as a scrambled mess, no menus. I could not get back to my NTSC S-Video feed which had been working. I kept getting the "no input", "new signal" flashing on screen and the glowing of a green raster on screen which would flash on and off but never sync back up to that working signal line I saved.

Did you delete any of the old signal entries ?

What about hooking up a computer directly and trying a progressive set of frequencies starting with 640x480 at 60Hz and then all the other standard ones up from there ? It won't take long to see if it will synch to certain frequencies, or if they're all an issue. Also, if it synchs, but you repeatedly get an "INFO" screen reading that is 10Hz lower in the refresh reading, that would point even more to the OSC board....

I may try that next. I was really hopeful last night when my S-video input was showing 60hz and it ran for over 10 minutes and I saved everything. Tried to switch to that 1080i source and it all went haywire again. What's with the "CINEMA" in the input description anyway? That sounds almost like a picture processing scheme from a flat panel tv or something. I had never seen that on my projector before, at least not on a CRT.
