.

Im definately no expert as are others in this site but ill give you my experience .

I set all my settings in the mg focus to 128 ( the sony neutral point ) , from there i adjusted my astig as best i could with the internal magents but used those electronic adjustments to fine tune it so all i can say is their there for fine tuning .

What i did was set it to the dot pattern in the service menu then from there with the MG focus i defocused the whole focus .

Innitially my little focused dot turned into what i could only describe looking like the plannet saturn as it turned from a ball of focus to a sharp line instead of a circle .

It was there i did my astig adjustments on the magnets to get it as good as round as i could again but then from there i played with the electronic controls til the saturn shape turned into a round ball .

After refocusing it back with the MG focus ( do this on the E pattern as well ) it was a huge difference and MUCH noticable when id do convergence because after i did it an the R G B all my scan lines were equal width and none of the colour flared or bloomed over the others .

I hope this is the reply your looking for as maybee im talking total basics and have mis understood the question but im just trying to help atleast someone here on this site as im always the 1 getting help .... lol .

lol , i was in the same boat before i played with it .

Ive got a G70 and it was pretty ordinary and was about to sell it till i bought a coloromiter and adjusted allot of settings and then i bought Blue Ray , then Graham Johnsons set up DVD and got more out of the projector from his info and now ive ordered an IFB HDMI card off Moome but as with everyone else , we are still waiting but can assure you this is a massive jump from the component im using .

Id strongly suggest buying that DVD ( dont know if im allowed to post the link in this forum but do a google and you will find it ) .

If you want to talk in real time about the Electronic Astig and your on MSN , PM me your addy and ill add you to contacts and well talk :)

DQP means "diagonal quadrupole" and AQP is "a? quadrupole"? What exactly do they do? They're electronic astig controls? I thought astig had to be done using the tube magnets pole system by turning the magnets on the neck manually?

DQP and AQP are Sony's name for their electronic astig controls for the G70 and G90.
"D" is diagonal and controls the beam shape diagonally. "A" is axial and controls the beam shape on the X/Y plane.
There are no CPC magnets to speak of on the G70 and G90 and it is all done electronically.

If you look in the setup manual they have an explanation with pictures.

So Terry are there any magnetic adjustments on the G70 G90 that are done on the tubes themselves. I've always just gone through the magnetic focus menu and the dots look good to my eye.

im confused , my G70 does have 2 adjust magnets and they did make a difference on mine when i set it

I wish everyone could use the same terminology. Like some use Bow for Pin and Keystone for Tilt. Then the Europeans have to be all cute and call a flyback transformer an LOPT......

Bow is NOT same as pin and KS is not same as tilt. They are using wrong terms.

I was pretty sure those were the terms Graham was using on his DVD and when done with the projector (1292) were acting the same way as the Pin and Tilt commands on my Dwin.

I was looking at the 1292 manual. The registration commands are skew, bow, pin, key, lin, and size. My Dwin has: pin, lin and size. So I assume those are the same as my Dwin? But I don't have bow, skew and key. My Dwin has Tilt which isn't an option on the 1292. I'm assuming either bow, skew or key corresponds to my Tilt? Even if all those correspond to my Dwin's commands, there's still two more options which my Dwin doesn't have. What do the two left over do which the Dwin doesn't have do?

As Capstain has pointed out they are not the same.
Bow is referenced around the horiz & vertical centerline, Pin the edges.
Tilt the centerlines and Key the edges.

There is one set of tab adjustments on some (not all) G70's. Manual explains that there are more on the neck which clearly there aren't. This was an error in the manual. Nornally you shouldn't have to touch the tabs that are there and all adjustments are done electronically.

You wanted a Dwin because it was small and quiet.

And now you want a 1292????? They are HUGE, LOUD and they streak. Enthusiasts only.

Get a G70 - I keep telling you that that's the PJ for you. The only downside to a G70 is the AKB line (as with all Sony's bar the G90).

With some firmware levels the AKB can be disabled on a G70(Terry?), but you may run out of adjustment range.

1292 has AKB as well. It can be disabled, but again, you may run out of colour adjustment range.

You cannot mask AKB on a LC tube. And it is clearly visible on black velvet on the wall.

Sonys are designed to run with AKB on, except the G90 which turns it off after 30 mins or so automatically.

NECs are designed to run with AKB off :)

No CRT projector is reliable. They are 10 years old now (ok, Marquees are still in production, but the rest aren't). You need a spare chassis and the ability to fix it yourself.

Get a big plasma then.

You will not just "watch movies" with a CRT...it will replace your wife and kids as the centre of your attention...

Reio, I love CRT PJs but that pic you posted looks like a $1000 LCD projector from 2003! New 1080p projectors may have lousy black levels, but you'd be hard pressed to see screen door from .8x. We use them in our motion platforms and have a 50" screen at about 30 inches - and the screen door is barely visible. You can see pixels, obviously; the field of view is about 70 degrees. But screen door isn't an issue.

There are plenty of reasons to use a CRT. Screen door isn't one of them.

As far as astig goes, my experience is that

a) It is absolutely essential to get it dead nuts. Aside from optical focus, it seems to me to be the most fundamental PQ adjustment.

b) It will be utterly obtuse how to do it right for about two hours. You'll twiddle and twirl (or run electronic controls up one way and down the other). Eventually, you'll go, "aaaaagh!" and leave. Then you'll come back, spend 15 minutes, and you'll start being able to direct the astig to improve dot focus. You will still have absolutely no clue how you're doing it, but you'll be doing it anyway. :p

So, there you go. It would be my two cents, but with the dollar the way it is it's more like three and a half.
