I was able to purchased a used one today from a fellow member for a fair price. He has a high end scope theater and was very pleased with it's focus and convergence. It was purchased through AVS a few months after they came out so I assume it has the 002 lamp. It's over 400 hours and he has not experienced much dimming. If I'm happy with the projector, do you guy's think that it would be a good idea to replace it with an 003? Since I finally got a good deal on it, I wouldn't mind forking out some more cash for the 003. I know a 003 can go bad, just like any other lamp, but it seems to have a better track record than the 002.

My indecision over these past months may have actually saved me $850. I was going to buy a new one Friday but didn't due to illness I had to wait until Monday.

Like they say, timing is everything.

The seller is a GREAT guy and offered to help me out if any warranty issue arises.

Now I'll have an RS55 for 2D, Benq W7000 for 3d , a 2.925 CIH screen and Navitar HD conversion lens so I can fill all aspect ratios.

Tom

Tom, glad to hear you found a good one. Do you also have a Darbee as well? My general setup is MPC=2 on the JVC and ~ 35% on the Darbee./

Yes, I do have a Darbee. Thanks for sharing your settings with me.smile.gif

I seemed to have missed this issue.

What are the purported advantages of this mysterious 003 bulb? My RS55 has it's original bulb so I'm curious.
post #3424 of 3669
My 002 Series bulb exploded at 1500 hours and leaked a gaseous mercury shard dust residue. It was not fun to clean up, though I did get about as many hours as I was expecting.

I mean:

# 1) The most compelling evidence that little has changed is that we are hearing very little about 002 or 003 lamps lately. The sample sizes have been greatly reduced compared to before.
# 2) Many JVC owners in here sold their projectors, changed, or upgraded to a newer JVC with different lamps.
# 3) Many JVC owners in here bought a second projector, especially ones that had issues with lamp usage or 3D.
#4) Even if you had an 002 lamp blow, that kind of automatically psychologically makes you more fearful of putting as many hours on it.
#5) Even though the 003 lamps have been out a while, they have not been out nearly as long as the 002 lamps, so it is so so EARLY. Remember the RS-40/50/60 lamp issues (001?) were a big part of the sample size, not just the RS-45/RS-55 lamp versions.
#6) There is more competition now against JVC than before, and there are more models.
#7) The JVC and Sony are no longer the main 3D games in town, a lot of RS-40's sold just because it had 3D early on before many other projectors had it.

There is no evidence that the 003 lamps are better than the 002, the only evidence is that they added a flapper. Other than that, we have nothing to go by.

I know my opinion is an unpopular one, and I am a JVC owner myself, so I don't want it to be true, I am just telling you how I see it looking at it purely statistically and not emotionally.
post #3425 of 3669
Basically, I hope I am wrong, I am just saying nothing conclusive yet. I know after I had a lamp blow, I will put fewer hours on the JVC for HTPC usage, I will now use a Benq for that. Hopefully I can get 1000+ out of the 003 lamp so that it lasts 2 years for me or more.

It isn't the end of the world in any case, I put more hours on my projectors than most do.
post #3426 of 3669
we can go through any thread and read about an occasional lamp exploding lamp exploding. I realize it stinks, but it's not entirely unexpected considering how volatile the situation is inside that tiny glass element which cranks out a considerable amount of light.

I don't think there was ever enough information gathered to track the JVC issues.

Looking at the lamps close up, there seems to be more changes with the air inlet than anything else. There is definitely a larger fan / opening feeding the locations of the lamp where the flapper is located.

JVC_LAMP5.jpg

to answer my own question, yet the inlet fan is noticeably larger than the older models.

JVC_LAMP4.jpg

JVC_LAMP1.jpg

JVC_LAMP.jpg

Upon close inspection, I don't see an obvious difference in the stem on the new / old lamps, my gut feeling says it was airflow all along after seeing the modifications to the fan inlet. You can clearly hear and see this is a larger squirrel cage fan.

I've attempted to mitigate any airflow issues by running High Altitude mode since my lamp was new and it didn't drop anywhere near as much as my 40 and 50 did at the same hours. probably luck, who knows. The HA mode on the RS55 is still a bit quieter than the 46/4810 in regular high lamp. if the increased airflow helps the lamp life, it's at the expense of a bit of noise. Most reviewers have stated the new models make a bit of a racket in high lamp.


Rich, any JVC replacement lamp you get now will have a small metal flap in the air inlet path. Much has been written about it, some speculated it broke up the airflow to create some turbulence to jet the hot air that was building up inside the lamp.

Thanks.

I guess I'll just wait to see if my lamp explodes.
post #3428 of 3669
I agree with Zombie for the most part, though I will say there definitely was enough evidence in past forum posts to show that JVC lamps had a tendency to explode or fail early. It wasn't that the lamps just failed, like most projectors I have owned (though it can happen), many JVC owners reported such a high propensity of exploding lamps, and at early hours too. I mean I am myself not a VALID sample, because it is too small, as Zombie noted. That said, there weren't very many people that got 1500+ hours out of an 002 lamp without it dying in a bad fashion, I remember 5, but I remember 100 posts of dying, cracked, or exploding lamps.

That is unusual given other projector threads, it is fairly rare for lamps to explode (yes it can happen), but you don't see it repeatedly being mentioned over and over again, a little in the Epson thread. I watch threads like a hawk and I have a pretty good mind about stats, so I am sure there was an off-balance, even though the sampling methods are faulty, there can be a propensity of overwhelming evidence with faulty sample sizes. People did not only have one lamp explode, but sometimes 2-3 in a row.

All this said, most people do not put enough hours on the projector for it to be the biggest concern in the world.
post #3429 of 3669
Whoa, I hope if they explode it isn't too loud. I have sensitive hearing!

What type of hours were there on the lamps that exploded?

Thanks.
post #3430 of 3669
you won't likely hear it if it happens. The element in the lamp is quite small.

For those that it happened to with the early lamps, the lamps started to dim noticeably ahead of time. not in every case, but possibly an early indication it was time to change the lamp.

check your pm for some interesting lamp info.
post #3431 of 3669
Flicker and dimming are the 2 main signs of premature lamp failure or the potential of an impending explosion.
post #3432 of 3669
It would be interesting to plot dim/flicker vs hours. My lamp is coming up on 500 hours.

My 002 lamp in my RS40 dimmed noticeably around the 450 hour mark then died but didn't explode. My 003 lamp is at 530 hours and has only dimmed as expected and is still going strong....oh geez, I hope I didn't just jinx myself. wink.gif

post #3434 of 3669
Well I wasn't too upset, since I got 1500 hours out of the 002 lamp, so that is a shocker to some I guess, though I seen a couple people get 2000+ hours. This another reason it's not so easy to know if a lamp has become more reliable, I mean I could have just as easily gotten 500 out of one then 1,500 out of the second, did the lamps improve, well that doesn't necessarily mean they did, as I'm the perfect case for this since I got 1,500 hours on 002. What if I get 1,000 hours out of the 003, what does that mean, to tell you the truth --- nothing.

I am not trying to be argumentative, if I came off that way I apologize, I really was just stating my opinion on the matter, for better or worse. I know some people like to see the glass half full, but I prefer to measure it with a laser...
post #3435 of 3669
Can someone tell me what a good price for a used RS55 would be? I have an opportunity to buy one with 350 hours on it from a dealer and will get the full 2 year warranty.
post #3436 of 3669
I am not really completely sure, so a used one with a warranty, probably around 3.2k is standard (not sure what I'd call good, maybe 2.8k).
A used one without a warranty, that is a tougher call, maybe 2.5k, but I know most ask too much on places like E-bay.
post #3437 of 3669
I won't really know if I got a good deal until I get it set up. How the focus and convergence is will play a big role. If it's a very good sample than I will consider it a very good deal.

I'd be more concerned about the focus uniformity vs. the convergence. As long as the convergence isn't off by a mile it can usually be tweaked with a combination of single pixel in the center and the 1/16 increments on the outside.
post #3439 of 3669
I've seen one JVC (RS-20) with bad focus uniformity, and one with maybe so-so (RS-40), but I have not seen any other modern JVC with bad focus, though I think Zombie had an RS-40 with bad focus.

The other issue to check for is if you see RED pixel drift, the funny thing about my RS-45 is the RED pixel drifts into placement after 15 min warmup in my average room temp, whereas on the RS-55 I just tested, the red pixel drifted out of placement. It can be hard to adjust convergence exactly because of the drift and room temperature changes and convergence "uniformity / unevenness", plus the side effects of adjusting in small increments across the screen at different points (though I think some claim 1/16th to 1/4th is great, or 1 full pixel, but beyond that is "risque"), 1/4th to 1/2 is danger zone.

Also,
Let me just say that having seen many many Epsons, the JVC completely beats the Epson in quality control with both focus uniformity and convergence, in no small way either.
I think JVC is #1 in lesser sample variance besides DLP.

@nohjy MSRP is $7999 putting $4k at midpoint. If you can do better than that, then go for it.

He can get one new cheaper than that from AVS last AVS sold them, if AVS can still get them (but that's a BIG IF). There were MFR Refurb B-Stock 55's not long ago on Ebay for $3k with full warranty, that is what I was basing it on.
post #3442 of 3669
Wow $3k is awesome. I wonder if the CMS works on them any better than mine. Someone, maybe you, said the CMS in the new models actually works. If so, then IMO he should buy a new model.
post #3443 of 3669
I didn't see any major changes in the CMS in the new models. The 4810 in particular needed some tweaks in green that the CMS couldn't fix. ironically the less expensive RS46 was closer to R709 out of the box and has good saturation tracking.
post #3444 of 3669
I can't dial in reds and blues with CMS on my RS55. Grey scale tracks well and picture looks great, so I guess I have to go with a video processor to control the colors. Then again, maybe I'm being obsessive - no one has complained about incorrect color. They just go on about what a great picture it produces and I don't even have a Darby in the chain...yet.

If you cannot dial in Reds or Blues chances are an external processor will have the same issue -- if the colors are undersaturated they cannot be fixed externally (external solutions cannot expand the colorspace).
post #3446 of 3669
eek.gif Thanks Geof. I will look at different gamuts to confirm it's across the board. If all are undersaturated, then I suppose I am SOL.
post #3447 of 3669
Were those the 55's or the x70's on ebay for 3k?. Myself and others, were unable to verify that the 3K x70 refurb seller was authorized.

The RS55's refurbs from the jVC store on ebay are at $3995 or best offer.

If my 55 turns our to be a good one, I think I will have gotten a bargain. I've been looking for this projector for months and got it at a lower price than any I have come across.

Mike Garrett said AVS had an opportunity to get some refurb 55's but the price was too high to make good business sense.

Yah perhaps not authorized, but saves quite a lot, could have enough left over to add another third-party warranty.

Try stage mode, this is the one I use with the RS55 / Mini 3D combo.

I was able to get mine for 2900 shipped. It was originally purchased by the guy through AVS. How does one go about getting an third-party warranty?

Thanks,
Tom
