JVC RS1000 / 2000 Anticipation Thread

[DavidHir]

I wonder if it's just going to take a complete redesign from ground up (where they don't want to spend the money), or they really don't know how to fix it.  I agree, it's rather odd as the issue as always existed starting with the SXRD RPTVs from the mid 2000s.  But at the same time, Sony probably figures only a small amount of people care and an equal (or greater?) number of people defend their products relentlessly and even deny the issue exists to this day.

It's also one of those things that happens slowly over time. It's not something you're going to notice from one day to the next. So that really helps Sony not lose too many sales as most people aren't even aware of the issue.

I've shared this story before, but the first SXRD unit I had in house was a B-Stock VW90ES that I bought from Mike at AVScience. At the time, I had a Sharp XV-Z30000 in house too. This was long before "SXRD Degradation" was even talked about. I power the unit up for the first time and I was dumbfounded with what I saw. The black level, with the DI engaged mind you, was dramatically worse off than the Sharp Z30K. I thought I had the unit set up incorrectly with something within the menu system. I think I measured something like 800:1 with the DI engaged. I spent a few hours trying everything I could to fix the issue only to conclude the unit was broken. I called Mike back to let him know I had received a lemon. Obviously later I found out this was very common to see on SXRD projectors. It seems the "countermeasures" help slow this degradation issues down, but based on Jeff's and Arrow's (Nigel's) experience they're still seeing these contrast, color and gamma issues on currently selling units.

In 2007, I bought a Sony 60" SXRD A3000.  I think there is a possibility that particular engine block was used in their front projection because I was in the service menu and found some codes that seem to indicate FP including one that would invert the image for front.  On any rate, I started noticing less than a year my contrast was getting worse.  The blacks just weren't as deep as I watched movies at night with the lights off.   When Chad came out for a re-cal, everything measured worse including blacks and the gamut shrunk and couldn't be improved.  The TV had a standard gamut (that was reasonably close to rec 709 out of the box) and a wide gamut option (oversaturated initially) but I had to switch to wide because the color was otherwise so dull at this point in standard mode.  However, I had to live with oversaturated colors but it was still preferable.  Not too long later, the blacks started looking to have a blue-purple look which was pretty much the final straw before I got rid of the display.

This is what I think was the last calibration report which I still managed to keep.  Talk about a mess! But this was the best it could calibrate by this point in time.

Seems to be delayed for an unforeseen amount of time:

wow

[AVSCraig]

Hopefully they will get this corrected soon. Still, not going to happen by Xmas I'd say.

[Dylan Seeger]

I wonder what the part could be. Is it image related or hardware reliability related? My guess is the later. Maybe a cooling issue that would cause premature failure of components inside?

Don't know, but there are preproduction units out there that are being viewed and yet no one is reporting an issue, so it is not something that is glaringly obvious.

Yep, i have not had one glitch with the NX9 i have here...    Put about 30hrs on it now..

Extremely jealous you get to play with a pre-production model. Enjoy it! Are you capapble of taking some on/off contrast measurements? How does the dynamic iris appear? Can you notice it working with regular content. The old one found on the eshift units was very good overall, but could use just a little help. Sometimes I could see it flicker as if it couldn't make up it's mind on where to position itself. I took this video a long time ago to demonstrate this issue.

First video shows what the iris does and the next shows what this flicker looks like on screen:





This might happen a few times during most of the movies I watch. I know...not a huge issue, but it's an artifact I only see on JVC projectors. Sony, Epson and some of the better DLP units don't seem to have micro flicker of the DI,

[dlambe10]

Is that flicker a common thing with JVC? I have not had a projector since my Panasonic AE7000, and have pre-ordered the NX7.

No, it's not common. Just like all projectors with a dynamic iris, there will be some artifacts on occasion. With JVC's eshift units I might notice the dynamic iris working 2 or 3 times during a movie. This is about as good as it gets from projectors will a dynamic iris. Sony is really the only other manufacturer at this same level when it comes to dynamic iris performance.

Any more impressions ? How many hours have you put on the NX9 now ?  Thanks.

Light at the end of the tunnel.

It looks like it's going be a very merry Christmas indeed! Great news. Hopefully we get these in-house sometime in January.
