For those who know, if the machine has stuck pixels, are they noticeable while watching a movie or HD. There is someone selling a G15 with 3-4 stuck pixels for a great price. There are 2 blue stuck off pixels, one in the mid-upper left portion of the

screen and another in the upper right portion of the screen. He found them by doing a surface scan of a solid blue pattern from a couple of feet away. There is also one stuck off red pixel in the mid lower mid right portion of the screen. He believe that these are actually 2 pixels that are adjacent to one another.


So the question is, will this distract from viewing, or is the pixel issue overblown?

Humey,


I don't have any pixel issues myself, but would think that stuck "off" would be a very minor deal. Remember that there are over 4 million individual pixel elements (counting R, G, B separately).


Stuck "on" is a different story, and although small, I would still find it distracting.


However, if you don't bite yourself, let me know through private e-mail where to find out more about it....I'm interested. I am looking for an economical second D-ILA.

Hi Humey,


I have recently discovered a stuck-on red-magenta pixel to the left of center screen. It appeared without prior warning :) at around 150hrs of lamp use. Like Mark says, there are so many pixels in the Dila grid, and the picture is so dense, that once you watch a movie, you'll have to look for it to notice it. Especially during a movie that has no outside bright shots. On the other hand, I do notice it right away, and it becomes quite distracting, when I watch something like a Disney cartoon animation, like during the Pixar intro. It is very noticeable when the blue Pixar screen is up.

Humey,

There is a great difference between stuck on vs. stuck off pixels.


I've got two stuck off blue pixels right together on my G10 clone. The only way I can see them is if I put up a blue screen and walk up to it. When an all white screen is projected, the area is slightly yellow, again at close range.


Stuck off pixels are a non-issue, imho. (Lcds & d-ilas, not dlps)


I've seen many stuck on pixels when I went through a bunch of Epson 710c 's. Even one is easily seen and very distracting. The best 710c I finally decided to keep for work had one stuck on blue pixel. Green and red pixels on the 710c appeared much brighter and disturbing.


Stuck on pixels are a deal killer, imho.

Are you saying that there is a bit of a difference between stuck ON and stuck OFF ? <big grin>

Well I have a stuck on red pixel. Just one on my DILA but it is very close to the center. It does distract me. I may just get it serviced under warranty, but it is a pain to deal with due to shipping and such. When my Panamorph arrives it might help a lot because the Pixel will then be about 30% smaller than it already is. Clusters of bad pixels are even worse. But this is my opinion only.

Cameron,


You may already know this, but the SE JVC Service Center is about

an hour or so away from you (non-rush hour) up in Duluth. My G11 is

currently there getting serviced - I much preferred to drop it

off rather than risk shipping it. And I assume they service it

on-site since they told me they didn't need the box.


They say it's about a 2-3 week turnaround for professional products

like the D-ILAs. We'll see - mine's been in for about 2.5 weeks now.


Take care,

Robin

So if you have pixels stuck on or off, you can take it to a JVC service Center to fix it/them??


Does this cost anything?? What is their spec for bad pixels where they decide it is a problem that may be handled under warranty, and when do they say 'tough luck'..??

Robin,


I didn't know that. Well that will make my servicing much easier.


Thx,


Cameron

Cain,


The thread at http://www.avsforum.com/ubb/Forum10/HTML/003379.html discusses the acceptable versus non-acceptable criteria for the Dukane

projectors and surmises that JVC's policy might be similiar. But,

as far as I know this is just speculation.


I'd call JVC to see what their policy is on this before committing

to a purchase. Ironically, it might be better deal to purchase a unit with

more dead pixels (esp all of the same color) and getting it fixed as

opposed to living with a unit with only one or two dead pixels, depending

on JVC's policy.


JVC's service website is at http://www.jvcservice.com and lists contact

information, etc. The e-mail portion of the site appears to be broken

however (at least it was 3 weeks ago).


My unit was an MVS showroom unit that shaded everything red along the

right edge, basically blending the image more red as it approached

within 1-2% of the edge. But no stuck pixels. If JVC fixes it properly,

I'll have gotten a fairly good deal.


Take care,

Robin

One important thing to realize is that 'getting dead pixels fixed' by JVC does not imply you are guaranteed to get a dead-pixel-free projector back. All they will do is swap out the 3 imaging chips for another set of 3 that are within spec. These new ones could very well have dead pixels as well, and the overall result may be worse, not better.


For this reason, I wouldn't take my chances trying to get a DILA fixed unless it has stuck-on red or green pixels. Stuck-off or Stuck-on blue (which is pretty unnoticable as well) are probably not worth fixing, because you could end up with something worse!
