I bought this PJ in 2007 for what I remember was quite a bit of cash - I assume pj tech has moved on a lot in 5 years and I wonder if a repair is even cost effective?

I have searched for this specific set of led combination but not found anything. It can't be temperature related and I have cleaned the filter.

Any suggestions?

Thanks!

Near impossible to know what it is. But the fact the lamp does light up initially makes me think there is something else not working. Being out of warranty it may not be worth fixing, though I cannot say that for sure...

I will add that I would not buy the lamp until you know... Lamps are not returnable and if it were an expensive repair it would end up wasting you the lamp.

Do you have any old bulbs you could try? Sounds like this projector doesn't have a lot of hours on it if you don't have a spare old bulb.

I had been considering upgrading to a new projector, but with another new bulb installed our old reliable RS1 still puts up a stunning picture. Looks like I can put off getting a new projector for another year or so...

Took a risk and bought a new bulb this time from Electrified since their price is so low. My 2nd bulb had "only" 1700 hours on it (got nearly 3000 hours out of the first bulb), but I figured that with new bulbs now so cheap, they're probably worth replacing every 500 hours.

Well, it appears that my experience with a new bulb and housing from Electrified may have been too good to be true.

Last night with only 104 hours on the new bulb, the projector suddenly went dark with no warning. The top 3 lights on the RS1 indicated:

WARNING: "solid red"
LAMP: "flashing orange"
STANDBY/ON: "solid red."

The remote wouldn't shut it down, so I disconnected the AC power and let the projector cool down. Plugged it back in and STANDBY/ON went to "red" (normal). Turned the power on with the remote and STANDBY/ON went to "green" (again, normal). However, the bulb never lit and the fan never came on. 30 seconds later the RS1 went back to the red/flashing orange/red error mode originally displayed.

Swapped out the new 104-hour Electrified bulb/housing with my previous 1700-hour JVC bulb/housing and voila, the projector is back in action (although noticeably dimmer than with the Electrified bulb when it was working).

I had been really pleased with the new Electrified bulb since it seemed to be maintaining very high brightness (I've always run the projector on HIGH to properly illuminate my 132" 16:9 screen), and its cost (about $100) was only about 1/3 that of a JVC bulb. I'm tempted to give Electrified one more try -- maybe I just got a bad bulb?

Added: It turns out Electrified has a 150-day replacement policy on their bulbs, so they're going to send me a new one. I'll let people know if that one also fails prematurely.

I'm going to be selling my RS1 soon but I'm physically away from the unit at the moment. I'd like to set up an auction before I return home, so does anyone know how much a packaged RS1 plus remote and manual weighs?

Also, I've been using a Peerless ceiling mount with it. Should I sell the mount as well or is this something I can re-use when I upgrade to one of the new flagship JVC projectors?

I had the same exact problem with them and a bulb for my Infocus 7205.The first bulb did exactly what yours did, strange how that happens sometimes two different projectors same problems. It turns out that I had a bad unit (duh only had 30 hours on it!) and they shipped a replacement in a couple of days. Installed new bulb and never had a problem with the replacement! I wish you luck it seems on which source they receive them from is the key.

I have the RS1-X and have tried buying bulbs from non JVC bulb companies that both claimed to use the same bulb as OEM. Apex Bulbs and MWave.

The bulb from Apex lamps looked good and worked fine initially, but around the 10th day, the projector lit the warning lamp claiming overheating. I cleaned the filter and powered down for a while, but then two days later the same thing. I was able to swap it for another bulb, which I decided against using and will just sell.


After a year with JVC bulb and no issues, I decided to try MWave. The initial brightness was possibly a little less bright than brand new JVC but comparable to the brightness of JVC after first 200 hours, which is very minor. I was actually happy with bulb and just in case bought the 6 month warranty. Unfortunately, warning light came on after two months, but I was because light element broke, basically what a regular household bulb does when it burns out. I have a new bulb on way, but think I can maximize my return by selling both lamps in their current brand new from company and never used state.



Is this common for these generic bulbs, or is it something to do with just the RS1X model? What's everyones opinion on selling these, should I mention my issues with past bulbs or just sell them as they are, new unused generic bulbs from the company. I guess the reason I ask is because I am an honest person and would feel bad if someone had a similiar issue unless it is common knowledge that the generic bulbs have these type of common issue?
post #8619 of 8732
It would mostly depend on who made the lamp, or that's my opinion. I figured out awhile back what Philips/osram works in a RS2 and for me they work better than the JVC made by Iwasaki. I never had problems with the amount of hours with the JVC lamp, but of the 5 I personally have seen in two different PJ's, they start to flicker around 500 hours. That always bothered me and even though I could get them to stop by using the high mode, they would start it again after awhile.

It took me awhile to find my old post in the RS2 thread, the search on this new forum basically don't work.

Anyway, for anyone that wanted to just replace the lamp inside the cage, the Osram part number is 69471. I never was able to find a Philips number but the style of lamp is - 200W 1.0 P21.5, which is what one needs to know anyway.

It is brighter than the orginal, I didn't try a light meter on it myself but could see it. Someone else did and said Osram was about 25% more at the beginning. I have a Philips and it has about 1300 hours and never flickered once so far.

In the past Apexlamps used Philips but I have no idea if they still do or did that on every order. I looked at a couple that some people had purchased and saw it was Philips but that's been quite awhile now. There are a lot of less quality lamps around these days. But just take the 4 screws out and its on the bulb itself who made it. Some companies go by a code number but after market usually has a name. If no name on it then its just some company, somewhere. Osram came out with Neolux to compete with the off brands, but that lamp isn't the quality of original Osram.

If a Philips lamp cause a RS1 to overheat then I wouldn't know why, because it don't with a RS2. I don't really like generic housings though, because to much a new smell that last too long. I always use the original housing.

Here is a couple of links for just the bulbs if anyone is interested, or just search it of course.

Try to be fair is the best policy. I buy and sell, so I try to walk in the other person's shoes. For JVC, I always differentiate if it's a genuine JVC, OEM and others upon listing. This will give the buyer at least what s/he is getting.

post #8621 of 8732
Absolutely agree and I have sold many high end items and always go out of my way to give honest description and have 100% positive feedback on eBay.

The question wasn't wether to reveal they were generic lamps, that's what they are and that what I was going to sell them as.

The issue was whether to mention my issues with the old bulbs since these are brand new bulbs from company sent to replace bulbs with issue.



Regardless, I pulled the trigger on a RS45U from Jason here at AVS and will just sell bulbs with my RS1X and explain the issues I had with old bulbs and whoever buys the, can decide whether to use them or sell bulbs.

I know this was a while back but still on the newest page in quotes so thought I'd offer you my bulb if you are still trying to figure out what to do. Prolly too little too late but just an offer as I have two old bulbs that still work fine just a tad dim. If so send a pm. Thanks

Gentlemen, I have a new problem with my JVC DLA RS1X unrelated to bulbs but to image. 2 days ago when starting the projector up, I only get a blue screen. When pressing the remote, it tells me "no input". I rechecked all of the cable connections, dish tv and ps3 hdmis, the Yamaha receiver is getting the signals as I have audio. I've disconnected all of the cables and reconnected, same issue. The projector will display the dla logo and all test screens, plus the "menu"s from the remote. I even went ahead and upgraded the receiver to a new yamaha vantage a720, just in case the hdmi out was shot (wanted to upgrade anyway). So the question I have is, can a cable go "bad" just like that, it was a "best deals cable" previously offered via avs forum (many moons ago as the theater is now 6 years running). The projector was working the prior evening, now nothing, doesn't matter if its running the dish set top box or the ps3, just no image.

I have had this system running for 5 years now with no issues, have previously replaced the bulb about a year ago so it's not that.


Could the hdmi port on the projector go bad, I hadn't tried reconnecting from the hdmi 1 to hdmi input. Any thoughts?

thanks.

I would have thought that you would have confirmed that your cable was okay BEFORE you changed anything else. Cables can certainly do go bad somethimes. I assume you've already tried the other HDMI input socket since they can develop problems from the weight of the cable over time? Naturally, none of the other menu settings have been changed, right?

thx techman, it's a 25 foot cable from the receiver to the projector, I have ordered a new one from blue jeans cable which should arrive Saturday.

Don't you have a short one that you can just test it with?

Looking from the front of the RS-1, down at the lens (power on) there seem to be "blobs" at discrete positions inside the lens, see picture. If this is dust, can it be removed? I`ve done a lot of dusty restoration in the room next to my HT, and some dust always find its way into the HT-room. I thought the lens was more or less dust proof?

Unfortunately, unlike good quality camera and projection lenses that are assembled with air-tight spanner rings, the "cheaper" zoom lenses that come with virtually all (except Schneider/ISCO lenses) home theatre projectors are NOT dust proof. Mainly because the tolerances and the way these cheap zoom lenses move when they are made to zoom. Although it's "possible" to clean, if not done properly, you might cause more problems than you correct. When lenses are manufactured, they are assembled in clean rooms. The best you can hope for is to carefully do it in a clean place continually using filtered compressed air during assembly. If you do decide to try it, DON'T disassemble any MORE than is absolutely necessary.

BTW- In all likelyhood, those dust particles probably have NO EFFECT on the picture quality. It's more psychological just seeing it.smile.gif
post #8631 of 8732
Thanks! I can`t see the dust particles on the screen, but I thought the "haze" maybe has degraded the contrast over time. Is this "haze" visible on new lenses as well?

In the picture you posted, I really can't see whether the "haze" you're referring to is normal or not. When trying to look into a lens with light projected through it, what you describe as haze sounds normal. However, real haze in an unsealed lens, caused from years of being operated in an environment of polluted air, CAN develop a haze that WILL affect picture quality, but I don't believe that's the case with your lens.

In the past, they cemented lens elements together with a cement called Canadian Balsam. In movie theatres, because of high heat from the arc or xenon lamps, if white light was projected on the screen for more than a few seconds with no film in the gate, it would cause the Canadian Balsam to burn and/or overheat, which then causes the lens to look hazy (and even crazed) when looking into it. As a result, while the lens still projected a picture, the lens will loose contrast and NEVER focus a sharp picture again. The only way to really see the real difference is to compare it with a known good lens. However, today, high quality lenses don't use Canadian Balsam anymore, they developed a method to assemble the elements with only an "air gap" between them (no longer cemented), so those problems don't happen anymore.

In your case, unless you're sure that your picture quality is really being affected, I wouldn't fool with it and risk making a perceived problem worse.wink.gif
post #8633 of 8732
Thanks! No, I`m not sure if it really affects the PQ. I have the feeling that the picture has less pop than before, but it could be worn bulb, or other things. My 10 year old daughter and her friends use the HT much more than me, so it might bejust some extra hours :-)

Some of the JVC projectors were known for developing a haze on the glass in the lamp compartment. This haze on the glass was a result of off gassing of the plastic. This haze cut down on some of the light output of the projector, it did not affect image quality. That is the only Haze problem that I can remember associated with these projectors. People just removed the lamp housing and cleaned the glass.

Less "pop" is a brightness problem, not a focus or sharpness problem. That could be an old bulb or like the post above, dirt and/or cloudy bulb optics, which can be pretty easily cleaned. You should clean them, at least, anytime you replace the bulb.

I see exactly the same on my new X-30, so no worries.

My RS-1 was purchased used from the classified section of AVS and I've been using it in my new theater room for the past month. It's my first projector and I love the picture, but there are two things that bother me and I'm wondering if you guys that own or owned an RS1 but have experience with newer projectors can answer a question -

The fan noise of my RS1 bothers me. It's not loud, but I spent a lot of time and money soundproofing my theater room in order to lower the noise floor and reduce all ambient sounds, and that worked great, except for the RS1 fan noise.

Motion "blurriness" (not sure that is the right word or not). Maybe I'm just sitting too close and it's got nothing to do with the projector, but on camera pans, quick motion, any film directed by Paul Greengrass, I get dizzy. I can watch the same source but on my 50" lcd and have no issue. Again, this may be due to watching a 10' wide screen from 12' away and have nothing to do with the RS1, but I thought I would ask.

Would upgrading to a newer generation of JVC or perhaps one of the newer Sony's correct either of these issues?

Well, I recently did a calibration on a RS2 which I installed the OSRAM bulb thet had 100-hours on it. The bulb was replacing a OEM bulb with <1000-hours .... The bulb was over 30% brighter, however the important factor was the light spectrum was much fuller. Colors look better! Haven't gotten around to compiling a comparison graph of the two bulbs. I know I will never recommend an OEM bulb for the RS1/RS2 projectors.
post #8640 of 8732
nebrunner,

I've Sony HW10, HW15 and VW60 but decided that crt-black is more important to me than panning motion. I've also owned anything from HD1 to HD750 (except HD550); the latter is a JVC weakness and so is the fan noise (HD1 and HD100). Sony pictures seem to be flatter and less depth.

I believe the newer JVC and Sony would do better with motion. Fan noise is about the same (quiet).
