Ok, get this....

JVC repair center is claiming no fault with the projector. I think I am going to flip out.

My X30 lamp developed a flicker around 700 hours. I hope that's the worst I'll see of that sort with my cherished setup. I had a Panasonic PX60 with a stripe at the far left side of the panel. I don't like stripes on my screens.

So, the repair center that said my unit is fine must have pulled the blind guy off my repair and they noticed that the OB is buggered. $4300 for the repair and it appears that they will be fixing it. Not what I was hoping but I told them about the issue and said I will be houring it out before my extended warranty expires. I said they should upgrade me and then their hands are washed of me because I would be under manufactures warranty for the remainder of my term. Makes sense to me but I don't have an MBA distorting logic...rolleyes.gif

My DLA-HD250 projector just started showing the magenta bar on the right hand side about a month ago. I too thought this was bulb related, and just swapped the original at 2500 hours (I run the bulb on normal power always) and was dismayed to see the problem remains. Rear shelf mount.

I just started the warranty repair request process from JVC website, and was redirected to Projector Doctor (division of Mendtronix’s, Inc). I should still have about two months on my warranty, and will be boxing up tomorrow to ship out. Will let thread know what happens.

1. Build Date (if available)

Not sure but purchased 4/26/2011.

2. Date first put into service?

approx 5/1/2011

3. Hours on projector (chassis hours) when problem started?

2500

4. Hours on original oem bulb when problem occurred (if still being used), or hours when removed?

2500

5. If bulb was replaced, hours on replacement bulb when problem occurred (and brand, if known)?

n/a

6. How projector is operated - Ceiling or Table mount?

Rear shelf mount.

7. Average room temperature where projector was operated?

68-70 F

7. Average power cycle (i.e., number of hours operated each time projector was turned on)?

I use this projector in my living room for daily TV / Netflix viewing. It is not dedicated for sporadic home theater movie viewing. I usually use it for at least an 1-3 hours just about every day.

Here's a pic of the magenta band.

Has anyone encountered this issue on an RS35?

I see posts for the following:RS10, RS20, RS25, HD250...but not an RS35, which I believe was the first "hand-picked" components model.

Only asking b/c I'm looking in the used market.
Given the track record of JVC, I'm very hesitant to go any older than RS45/55/65, but prices on the RS35 are getting my attention.
Thank you.

I would avoid this chassis completely. While I dont think this effects every machine, the fact I had two die is alarming. When the second one started showing signs at only 600 hours I was especially amazed. My extended warranty covered repair or replacement and the repair would have came to $4300, so they gave me the option of a credit towards another purchase. I considered having it fixed but decided I would abandon the generation and move on. Sad thing is I dont have the scratch to pay the extra couple grand to get the X75r and settled for the X55r. I figure there should be a decent enough upgrade from my HD-950 and I get out of this merry-go-round of warranty claims. Also get some goodies like E-Shift and 3D, and I figure the only thing that the X75r has that I will really miss is the motorized lens cover. Will sell this unit when native 4K and LED or laser hit the market.

Sadly, yes, it's on our RS35. Bad. Such a shame, as we LOVE this projector. I was going to post about it tomorrow anyway, just finished researching this phenomenon, and have to gather the data requested in the original post, and take a photo.

But for quickie info: We got the RS35 3+ years ago (Nov 2009) from AV Science, first batch that were produced. The stripe began about 4-5 months ago, very thin and faint at first on the left side of the screen, now quite thick and bold, with a faint green stripe next to it.

Ugh. Warranty of course ran out, but credit card extended coverage might cover it. We'll see. Not sure what we'll do if not.

Thank you for your replies. Bummer on the RS35 et al.
Looks like I'll steer clear of everything before the 2012 line-up.

How thick would you say it is now?

Also, can any others chime in how long it has taken to go from thin to much thicker?

I am curious to see, perhaps, how long I might have before it gets too obnoxious?

For me my first unit was about 200 hours before it was from a sliver to about 3" on my 106" screen. Second went from sliver to 3" pink and about 14" of green hue in about 100 hours. Was really fast second time around.

To me it seems dependent on each unit as to how bad it is and how long it lasts.

Sorry for the delay, been swamped. I'll finally submit my details and a photo tomorrow!

As I gather others have experienced, I called JVC and they say they're not aware of this issue. The gent I spoke to said they don't call it a known issue unless most customers have it. I asked, "So if, say, 25% have defective projectors you don't call it an issue?" He said no. "50%?" No. But didn't specify what "most" meant, and simply said he wasn't aware of complaints about this. I've no idea how much he really speaks for the company, but I do wonder how common this issue really is.

Also, is it something to do with the technology itself, regardless of manufacturer, or is this mostly happening on JVC projectors?

1. Build Date:

2009 (first wave of RS35's shipped out)

2. Date first put into service:

Mid-November 2009

3. Hours on projector (chassis hours) when problem started:

Didn't check, but going on average usage (it began as a very thin, faint stripe ~4 months ago), perhaps around 1,000 hours. (Current hours used: 1,116.)

4. Hours on original oem bulb when problem occurred (if still being used), or hours when removed:

Still using original OEM bulb. Always at NORMAL lamp power.

5. If bulb was replaced, hours on replacement bulb when problem occurred (and brand, if known):

N/A

6. How projector is operated - Ceiling or Table mount?

Ceiling

7. Average room temperature where projector was operated:

70 F (varies from 68-73F)

7. Average power cycle (i.e., number of hours operated each time projector was turned on)?

About 1.5 hours. (Typical usage is 30-60 min. when used on weekdays, 2-3 hours when used on weekends.)


ADDITIONAL INFO:
Color stripes are on the left side of the image. Began with a very thin, faint pink / magenta stripe, and a periodically perceptible green stripe beside it. Gradually widened over ~4 months. I'd thought the green one was thinner, but upon looking closer today, I realize it's actually wider, just fainter.

On our 92" screen, the colored stripe is 3.5" thick total -- 1.5" is bold magenta, 2" is faint green.

Here are some photos of the screen:





Closeup of the stripes:

Glenno, does your stipe go away with use, or is it constant? After a couple hours mine--which looks exactly like yours does in the photos--goes away, but comes back as soon as it start it up again after it's completely cooled.

Just thinking outloud.
A magenta stripe means a problem in the green lightpath.
If, as you said, the problem decreases with the heat, I must assume that there is not a problem with the polariser but then there must be a fault in the green panel, some kind of retention that is blocking the light in this part (stripe) of the cristal. If you can connect a PC with your PJ, you could try to run an application like this one: http://udpix.free.fr/ and see if it fixes the stripe.

No, it stays constant while on. I had it on for many hours yesterday (a rarity for me), and it stayed the same. And only gets progressively wider over the weeks.

I'm sending it for service this week.

Looks like same problem I had with my 70"SXRD rear projection tv a few years ago. Had to get the optical block replaced 2 times. I have the JVC HD990 I will keep an eye on it and see if I get the same problem. I have around 1500h on the bulb, and my theater room is usually cold cause its in the basment.

HD350 bought brand new from "Richer Sounds" in Manchester, UK in December 2009.

Just happened last week, purple/magenta tint on left hand edge (more intense in lower corner than upper corner).

Really upset that it's out of warranty and clearly a common problem.

Shelf mounted in a climate controlled (via dehumidifier) underground home theater. (16-22 degrees C)

Still on original bulb, 2035 hours.

Projector used for 4-12 hour sessions and relatively consistent times between uses. No more than 250 power cycles.
Everything has been perfect till now.

--edit--

It also developed a flicker around the 800-1000 hours point. Very bad sometimes, but often disappeared when going to high bulb or switching refresh rate. It seemed much worse in 24p but I came to the conclusion it was a "feature" to make it look more like a film projector... Having read everyones comments it seems I was wrong and it is a fault. Makes sense now I think about it as why would a "feature" only show up after 800+ hours.

Also, I use the high bulb mode for anamorphic films and "important" 16:9 film showings (i.e. lots of friends round). And normal bulb for gaming and 16:9 films with just the family. So approximately a 50/50 spread.

After reading and speaking to people about this problem (that JVC claims to be unaware of), I don't think it's actually a panel problem. I believe that after time "dust" (or some other type of buildup on one or more of the glass filters) is the cause of the problem. However, after reading one of the posts claiming that "heat" causes it to disappear temporarily and then reappears. With all the replacements of the “optical blocks”, claimed to be necessary according to JVC. I haven’t heard any description of specifically WHAT IS ACTUALLY GOING BAD.

The “flickering” problem that has been described by many people, in most cases, is just a bulb problem. At this point, many people have said that when the flickering occurred, they ran the bulb on HIGH, which caused the problem to disappear. In some cases, for the rest of the rated life of the bulb. While there could be some cases where the power supply is involved, most of the descriptions would point to the bulb as the problem.

In any event, whatever the cause of both these problems, there are certainly enough people with the exact same problem where JVC should have at least warranted the projector for a SET NUMBER OF HOURS, irrespective of time. In one of the cases above in this thread, it is claimed that only 200 hours was on the projector when the magenta line occurred. That’s the ONE INSTANCE that totally confuses me, since with 200 hours the projector is barely broken in. He would have had to operate it the projector near a coal fired boiler to generate enough dust or dirt to cause a problem.

Although not the same problem as the JVC projectors, I recently tore down an optical block from a Sony SXRD RS projector. Before Sony started to replace them with an LCD TV for a small fee, they had been replacing optical blocks, which continued to go bad. Some company was offering to rebuild the OB, claiming that the problem was a filter, which they were replacing. I found NO BAD FILTERS AT ALL. It appeared that one of the filters, the only one backed by plastic, was completely clouded. While it could be cleaned, it would only cloud again because it appeared to be a chemical reaction that was taking place from the heat. If you’ve ever left a car in the heat, the plastic or PVC dashboard causes the windshield to develop a cloudy film, as a result of a chemical reaction to the heat.

Lamp flickering has been a problem on every brand of projector that is lamp based. The lamp gets a couple flat spots on the electrodes and the arc jumps to those spots. usually turning the lamp to high for several hours, gets rid of those flat spots, but they can come back again. As I said this is not a JVC problem. This is a lamp problem in general and applies to all lamp based projectors. Go to the Panny threads and the Sony threads and you will see people complaining about the same problem.

I noticed after leaving the projector on for about 6 hours the purple tint had faded almost completely which matches with what other people on here have found. I imagine it will come back again when I next go to use it.

Did anyone find out the cause? is it some dust on the edge of the green LCD panel which can be fixed with cleaning or is it a glue/peeling problem from heat drying out or expanding/contracting the filters?

I'll need to replace the bulb sometime in the near future and figure I'll give it a good clean while I'm at it. Incidentally, the dust filter I checked recently was spotless, not a single bit of dust and has been like that since I first started with the projector.

Lastly, debating currently how long to wait till I replace the bulb. The image is still perfectly bright and pretty much the same as new on my 13' 2.4:1 screen (using the zoom/masking method, not a stretch/compress lens). I still find my eyes hurt when someone in a film shines a torch at the camera lol. My only concern is the bulb exploding as I've read about online. I've had 3 projectors in the past but none of them I've had to replace the bulb yet and this will probably be the first (assuming the purple edge doesn't get worse). I was surprised the "change bulb" error stared happening at about 1900 hours. I thought it would be in the 3000+ hours mark. Since I feel I'm pretty good with conserving the bulb life (never turning it on/off more than once a day), I was hoping to get a very long life out of the bulb (at least 3000 hours). So I'm thinking of waiting till I notice a deterioration in brightness. Should I be more worried about the bulb exploding? :/

As a not on the flickering, it's true for me that running it on high for a while does stop the flickering. There's only been two times in the bulbs life where it was REALLY bad flickering, almost nauseating even. On the other odd occasions where it does flicker it's subtle and resembles a film projector's shutter which I actually quite liked when watching films haha

You're just confirming what I'm saying, namely that it's a bulb problem. That said, to add to the confusion, in a few cases it has turned out to be a power supply issue. In any case, it's pretty well documented that running on high will normally cure the problem....at least temporarily. When the flickering can no longer be cured by running on high, it's time to replace the bulb.wink.gif

1. Build Date - ???
2. Date first put into service - 12/15/2010
3. Hours on projector (chassis hours) when problem started - ~1200
4. Hours on original oem bulb when problem occurred (if still being used), or hours when removed - occurred on original bulb so ~1200 of bulb and chassis hours
5. If bulb was replaced, hours on replacement bulb when problem occurred (and brand, if known) - on original bulb
6. How projector is operated - Ceiling or Table mount - Ceiling Mount
7. Average room temperature where projector was operated - 65 - 80 degrees
8. Average power cycle (i.e., number of hours operated each time projector was turned on) - 2 to 10 hours typical. I have had some marathon ~20 hour watching sessions.

I have an DLA-RS35u that started exhibiting the magenta line along the left edge about 2 months ago. I first noticed it after powering up the projector after an extended period of non-use. My initial fix was to zoom out such that the line fell on the bezel of my stuart Studio-Tec screen. That works fine but is still annoying. After a few weeks the problem area got worst such that I've had to zoom out even more. I think I'm at about the limit of the zoom method as a fix. So if it continues to get worse I'll really be screwed.

At this point I have yet to contact JVC to verify my warranty status or to enquire about a fix. I'm really dreading taking the projector down and sending in for repair even if it is covered (which I doubt).

If any one has advice on the best number to call or how to navigate to a rep that will actually know about this issue that would be hugely helpful!

Unfortunately, I can tell you that it's definitely out of warranty, even though it was 3 years on the RS35, instead of 2 years like on the other models.

As for a "rep that will actually know about this issue ", I'm sure you'll be the first one with the problem they've heard about. rolleyes.gif

If he purchased it on 12/15/2010, or therabouts, it should still be in his 3 year warranty? I would get the ball rolling for the warranty repair as soon as possible.

I wasn't thinking.smile.gif It unusual for an RS35 to have been put in service almost at the beginning of 2011. While that doesn't mean it was purchased that late, if it was even 6 months before 12/15/10, there is still PLENTY OF TIME.....to be told this is the first time they've (JVC) heard of the problem.biggrin.gif

GET IT IN TO JVC AS SOON AS POSSIBLE!!!

I have a jcv rs15 and as of yesterday 1445 hours on the projector, the pink stripe started. I spoke to JVC today and they said they never heard of this before, After reading these post I see that they are full of it. I really like the projector and the picture but I see that alot of people are having these same problems. Not sure if its worth fxing or not, they would not give me a price on what it would cost to fix it. They should recall these projectors and help the people that purchased them, but you know they wont. What a shame JVC! mad.gif

It’s really disgusting that with all the posts about the “magenta stripe” problem, just posted here on AVS, that JVC could possibly claim they “haven’t heard of the problem”. rolleyes.gif

Since they don’t admit there’s a problem, they NEVER tell anyone exactly why the problem occurs. Even when it is “fixed” under the warranty, people are usually told that the “optical block” was replaced. There’s no way of knowing if they actually replaced it or not. But even if it was replaced, the an EXACT reason of WHAT in the optical block caused it still remains a mystery. confused.gif

In any case, the cost to replace an optical block is more than the projector is worth. In addition, since there’s no exact cause established by JVC, what assurance would you have that even if you were willing to pay to replace the optical block it’s not going to happen again? eek.gif

Another step closer to a class action. mad.gif

For what I can put together from my experience if you have a pre "X" chassis you a very vulnerable to this happening to your machine. Not worth fixing if it has happened because like techman says, you have absolutely no assurance that it wont return and your money is then wasted and you feel like even more the fool. Only way out is before your machine auto-borks itself, you sell it and then pass the possibility off to another. Also a nice eff ewe that JVC has kinda forced those who know to those who dont, and get out of the line completely. If it has happened dont fix the unit and just take your licks and move on.

One reason I stayed with JVC is perhaps internal rumblings and knowing absolutely that this is a large issue they fixed it in the X series as I have not seen any striping issues with them at all. The second is the new bulb and power supply in the X35X55/X75/X95 series as they are maintaining brightness like crazy. If I had not been lucky enough to have extended warranty JVC would be immediately struck off my list. But, not admitting there is an issue and playing dumb has not made them my first choice by any means.

To be clear to EVERYONE, when you say, the "X Chassis", you are referring to the completely NEW model line AFTER the RSxx series. I just didn't want anyone to think that there might be SOME "chassis" versions of the RS series that don't exhibit this problem.

That said, I just want to point out that I've read posts by people with the new "X series" JVC projectors claiming to exhibit the magenta line problem. As I've said in the past, my RS35 does not yet exhibit the problem, but, that's mainly because I have virtually no hours on the machine. Once it did develop the problem (and if it was wide enough and annoyed me enough), I would totally disassemble the machine to see if it's being caused by what I believe it is. If it turned out to actually need a replacement of the optical block (since they don't sell parts for it separately, only as an assembly), I would throw it out if was too much trouble to re-assemble.

That said, I STILL BELIEVE that D'ILA (LCoS) is the best technology for projection. Sony must also believe it since their DCI cinema projectors use SXRD chips, which just another name for LCoS (Liquid Crystal on Silicon).
