The PJ height is even with the top of the screen?

The AE3000 service menu looks very similar to the AE2000, so nothing apart from flicker adjustment (not needed on any AE1000/2000 or 3000 I've owned) to fiddle with. There are extra temperatures displayed in the 'self check' menu which refer to filter temp drop or similar, so this might back up the theory that the 3000 has extra filters then the 1000/2000.

OK. It looks like I don't really need the service manual. But just for information, where do I get one? Or are general consumers out of luck with this?

"A final tweak is that, as reported over on one of the German forums, using HDMI in expanded mode and recalibrating the contrast and brightness to match, does seem to increase maximum brightness without crushing whites. Until I get my Eye-one I can't measure it to confirm, but it certainly seems brighter, though the black level will remain the same. It may allow the use of an ND2 filter to improve blacks whilst maintaining a bright enough image as the German forum claimed a 20% increase in 100IRE output using this method."

Kelvin1965S, can you please elaborate on this? What do you mean, for example, by "us[ing] HDMI in 'expanded mode?' " and where is this ste?
Thanks for your reply

I contacted Projector People today regarding my convergence/color uniformity issues. I have no dead pixels from what I can tell. I have 30 hours on the unit.

Here's the reply I got:

Hi,

What I’d like to do is send you a prepaid shipping label, get your unit back here and throw it up next to a couple of brand new AE3000’s to see if it’s out of specs. It’s nearly impossible to find an LCD projector with perfect convergence, uniformity, etc., so I think this will be the best solution. If the AE3000’s we pull look the same as yours, we’ll get you in touch with Sarah to discuss your options. If the units are better than yours we’ll do a straight swap and you’ll be good to go. Let me know if this works for you.

Seems like a very fair proposal. I'm just wondering based upon the pics posted will I ever see an issue with normal viewing because of the bad convergence/color uniformity? My fear is I get a new unit with dead pixels.

Any thoughts?

I'm finding it very hard to see that you do have a convergence issue ??

If there is one place on those examples you should photograph them and not the whole pattern.

PP will most likely do a complete QC on any projector they would send as a replacement.

Also, you are pushing the envelope with 30+ hours on your projector. WOW! I am impressed PP is willing cut you that much slack.

Sorry I meant the color uniformity! Should the diagram not be all white if perfect?

aquafire, a crosshatch pattern is used for checking convergence
A soilid full panel gray scale pattern(30-100 IRE) can be used to check color uniformity.

What do you think of the PQ right now when you watch a movie?...If you are happy with it then that should answer your question. I personally wouldn't swap if you can't tell watching movies. Mine has a bad input (HDMI-1) so I just use input 2...(Not worth the hassle to swap for perhaps a worse unit). I honestly think we folks on these forums should actually "watch movies" on our projectors and spend less time tweeking with them and talking about them...speaking of which, I need to go watch Journey to the Center of the Earth in 3D...

So the images posted would not concern you? OBVIOUSLY this is all new to me. I noticed a post by another member with the same crosshatch pattern and his had very little blue on the image and the lines were mostly white. I also ran the same pic with my AX-200 and it had no blue at all...

With the same pattern up try lowering the Contrast and see if it turns more "white".

aqua... If you send the projector to PP and it checks out, you can take it back knowing you are good to go. If they find problems, they;ll send ya another projector which checks out.

Either way, I think you should take PP up on their offer for your own peace of mind.

When I was doing focusing up close on a mostly black image, they stick out quite a bit. I can't see them from my sitting position except out of the corner of my eye (and they are in the corner so it's a little annoying).

Good suggestion, although if the pattern does become more white it's probably a matter of gamma push under the dynamic iris.

I agree ..No I don't.
To test for 'uniformity' you have to use a White full panel test image, nothing else will tell you what your trying to find out.

Does DVE have a white full panel test image?

Sure does, run the 100 IRE pattern. You will be looking for different "hues" or tint on your screen. If there are any that's considered poor "uniformity".

Then run the crosshatch pattern from the disk. and put the pj in cinama 1 mode checking for the "White that your after.

DVE also has a resolution test pattern with a light/medium gray field and black lines/lettering. The gray field can also show reddish/blueish coloration the way a solid white field would show.

However, gamma shading errors can be good at one stimulus/IRE value and poor at another. It all depends on how well the projectors was calibrated at the various grayscale gamma shading levels. Sony has 11 gamma shading levels they calibrate. I don't know how many Panasonic uses.

Without a full spread of grayscale test patterns from 0% black to 100% white, you won't be sure to know if somewhere in the middle the shading is whacked.

You didn't state WHAT measurement you were inquiring about. He does indeed include "measurements", lumens and gray scale readings for instance. Re-read the General Performance page of any of his reviews.

Lowered the contrast by 5 tics...much more white. The right side now has a hint of red on the lines.

Where is the 100 IRE? I have DVE HD-DVD....

So can everyone tell me if they are using the HDMI "expanded" option? What does that do exactly? Seems to bring out a lot more shadow detail.....

And what do we think the "detail clarity" option is?

Thanks!

No, don't use "expanded". That will put your projector into PC mode. Normal is Video and what should use.

Clarity I don't have a clue

FWIW, color uniformity seems excellent on mine - almost perfect in fact. Convergence is slightly off and I'm still struggling to find perfect focus, but it's close. I finally got everything mounted, but have not really had a lot of time to tweak each of the modes. I'm curious to see what Art's review turns out in this regard though.

I'm glad I'm not the only one trying to figure out detail clarity. Didn't anyone ever teach Panasonic not to define a word with itself? I am paraphrasing but the description in the manual reads something like "Detail Clarity - Improves the clarity of details". WTF is that supposed to mean and what exactly is being done to the image???

BTW, has anyone messed with the gamma adjustments yet? I threw up a 7.5 to 100 IRE image from Avia and used the waveform to do a rough eyeball calibration making each of the levels from 10 to 100 approximately the same distance from one another and ended up with Low Gamma of +8 and Mid Gamma of +6 in Cinema 3. Anyone else seeing the same thing?
