I see.I can tell you, it's not moving.
Is it stuck in the closed down position then?

Yes. It seems so.I see.

Okay so that likely discounts laser malfunction. Could you grab an image of the iris in its current state inside the lens at all? Just curious if it has over closed or suchlike.Yes. It seems so.
I'll snap one next time I'm in there.Okay so that likely discounts laser malfunction. Could you grab an image of the iris in its current state inside the lens at all? Just curious if it has over closed or suchlike.
The noise suggests it has 'gone too far' and is proper wedged.
There's zone-by-zone panel alignment in the regular menu... is that not what you're referring to?
Correct. But you will see it if you play games and there is a grey sky, and sometimes appears in shadows (in games).How strange.
(For the benefit of anyone reading who doesn't have one of these projectors already: no, the picture doesn't suffer from pink blotchy patches with any kind of normal content!)
All good observations. I will say that the pink, blotchy thing can be fixed in the service menu. I has something to do with 'auto' panel alignment if I remember correctly. My dealer fixed it on my 760, so no idea how to do it, but I saw it on my previous sony before the 760, not at all on the 760 which the dealer had changed the SM setting on, and then saw it again on my 790, which hadn't been altered by the dealer. May be worth investigating.
And there it is. Thanks Ricky. I was a bit out of my depth there.It is not an 'auto' panel alignment as such, it is a factory preset panel alignment.
The problem with doing panel alignment is that unless it is single whole pixel adjustments (across the whole screen), it is a digital process and that can create artifacts (just like keystone), which are worse tan the convergence you are trying to improve.
Sony appear to be running a panel alignment in the factory (on all their VW projectors), which appears to be a zonal adjustment, and thus this creates the artifacts, some worse than others. By accessing the service menu it is possible to turn this factory adjustment off, and this can help to reduce or eliminate these artifacts. We do this on all the VW projectors we supply and/or calibrate.
Not should be turned off, but can be.No. The unit has an AUTO panel alignment feature that runs in the background. This is what my dealer told me. And it should be turned off. All units arrive with it turned on, and no one can fathom why as it seems to do nothing but cause the pink blotching issue. I'm sorry I don't know 100% about it, but my dealer told me this was the case, turned it off for me before shipping the unit, and the pink/purple blotching was gone.
It is in the service menu, which you do not have access to.
I can only disagree from personal experience. On my 270 it was a big problem with gaming content. Frequently seeing the pink blob artefacts in grey skies and in many shadows. My 760 didn’t have the issue at all, either in gaming or in test patterns, but my 790, there is was again. So from my experience at least, it is more problematic when enabled, though my experience is exactly that: my experience.Not should be turned off, but can be.
Not all units benefit so much from switching it off. It is certainly something that should be done on a unit by unit basis.
It only shows really shows in test patterns too. So nothing much to worry about and one has to ask why it is enabled from the factory and hidden in the service menu if they didn't think it was of benefit to have it switched on.

That was not my experience. Could tweak panel alignment manually to perfection with it turned off on my 760.If you use the panel alignment setting from the main menu, it makes no difference if the service menu one is switched off anyway.

Oh, okay, I see what you mean. Funny though, as the setting off, for me, eradicated the purple artefacting.if you use a test pattern, the one that goes pinky / purple. As soon as you engage any sort of panel alignment, you get this. Switch it off and it shows a true test pattern as it should.
Here you go. Not sure what it's supposed to look like when fully open, but whatever position it's in here in the image, that's where it is stuck.Okay so that likely discounts laser malfunction.

You sure that isn't DFO? It adds a lot of that ringing and red/pink contouring.I can only disagree from personal experience. On my 270 it was a big problem with gaming content.

Well, that shows that is it stuck almost completely closed.Here you go. Not sure what it's supposed to look like when fully open, but whatever position it's in here in the image, that's where it is stuck.
