I sold my RS40 so if anyone wants this lamp for experiments, you can have it for the cost of shipping ($10 paypal, continental USA, no guarantee, use at your own risk). It has less than 1 hour use. Maybe putting it into an original JVC housing would have helped with brightness?. I never thought of trying that. If you're interested, please post here on the thread. I'll PM the first poster with payment details. Don't PM me directly if you see someone else has already requested it. Thanks.
I'll take it and give it a try.

Thanks
Juan

MY Philips bulb turned up a few days ago and I fitted it in my original V3 JVC housing and it is definitely as bright as the original bulb.

The old bulb had done 1768 hours and was virtually cracked in half as you can see. Apart from a lack of markings on the original bulb the new replacement Philips looks absolutely identical.

PM sent. Hope you have better luck with it than I did.

I will try to take some pictures of it tonight and post here so others can compare. I could not find any markings on the lamp to identify the manufacturer.

Here is what it looks like. Main difference vs. JVC v3 original is the 2 wires inside the lamp.

Was the Philips bulb you purchased the $50 kind?

That seems to suggest that some of the V3 JVC lamps do use the Philips bulbs. Mine was like that too, although I wasn't 100% sure since I bought the projector used (but supposedly with the original lamp).

it was the one suggested by Dominic Chan, the link was provided earlier in this thread

I'm so impressed that I ordered another one in a compatible housing as a spare. They are 100 percent genuine Philips lamps from this seller, I checked mine with Philips themselves. I'd rather trust a branded lamp than one of the hundreds of cheap fakes doing the rounds.

I have read that they use Ushio, Philips and Osrem bulbs, Mine was a genuine JVC V3 and apart from a lack of markings on my dead, original bulb, they are visibly identical. Both have two wires in the bulb as well, not one.

Thanks for the link anyway Dominic, saved me a fortune, I'm in the UK and even with shipping and customs it only cost me £50 delivered. I ordered a spare one complete with housing and that came to £70 including international delivery and customs. Considering the cheapest original bulb in a compatible housing is around £200 in the UK I think I've scored an absolute bargain.

The cheapest Philips bare bulb in the UK online is over £100 and the original JVC replacements are £300-£400

Hey guys, I have a couple questions. First, this so called "flickering" issue - what exactly does it look like? I just started having issues with my first flapper bulb on my RS40, after about 1000 hours. But I wouldn't call it flickering. What happens is it switches between different levels of dimming. It will go dim, stay that way for a few minutes, then go back. Or it will alternate between different levels of dimness, none being full bright, but it always spends a few minutes at each level.

I just ordered a new bulb, thinking this one could blow any day now, but I'm wondering if this is the "flickering" I see mentioned here. I'll check my capacitor orientation before powering it on again.

Second, I see a lot of mentions of firmware version 1.8, but I can't seem to find this? I googled "RS40 firmware" and all I found was this page:
http://pro.jvc.com/prof/support/productupdate.jsp

It says the RS40 version is 1.5, which I already installed back in 2011. The RS50 and RS60 say version 1.8, but this is the RS40 thread here . . . Is there really a version 1.8 for the RS40, and if so, does anyone have a link?

Thanks.

My guess; it's your mb. Check that capacitor.

I checked the capacitor, and sure enough it was backwards. Fortunately, the capacitor was still functioning properly, so I put it back in the correct way. No dimming when I turned it back on, though I will have to wait and see, as over the past couple weeks it would go a few days without dimming problems, then a few days with, then without, and so on.

Anyone know about the 1.8 version? I found the official X3 firmware is 1.8. Can/should I install the X3 firmware on an RS40?

As a best guess, (and I have had the issue that is the same as yours), the flickering some are referring
to is the same dimming issue that you are talking about.
When it gets really bad it can go back and forth quickly, thus looking like low level flickering.
Another best guess since it really hasn't been confirmed 100% and probably never will be,
but I think your dimming issue is related to the backward capacitor.
The dimming issue may or may not go away for a while after you shut down or remove power from
the pj for a several hours or overnight, but eventually it returns.
However if you did fix the capacitor issue, I don't think your frequent dimming issues will be back.

The X3 1.8 is OK. I used a UK version when I updated mine some time ago. I forgot to mark down the version so I don't know what I'm on. It's too hard to check to see what you have installed.

JVC-RS-40 Lamp 'exploded'...

I purchased my JVC-RS-40 in May of 2011 and had it dealer installed. My projector has worked perfectly, until last night, when the bulb 'exploded', no damage from what I could see after I removed the lamp assembly.

I have read with great interest all the post here in AVS regarding replacement 'lamp bulbs' for the RS-40.

I only noticed my picture dimming over the past couple weeks. I did not look to see how many hours I had on my original bulb (I do know it was a '002'). I plan to check to see how many hours I actually had once I receive a replacement bulb. I will then reset the hours meter.

I have ordered from Mendtronix their part number: MTI-81877: "Cobalt Lamp Assembly with OEM Bulb and New Housing: P/N: PK-L2210U", for $189, with free shipment. I will post a follow-up as to how everything works out.

Welcome to the club. I had two different lamps EXPLODE in my RS40, including the original lamp that had less than 1000 hours on it.
The projector sits directly over my prime seating location, and over time the fabric on the seat deteriorated, cracked, and pealed off.
The fabric is imitation leather, but since they are theater seats, they were not cheap.
The glass dust and mercury from the lamp is what ruined my seat. Now I have a blanket covering the seat since there is no way
to actually replace the modular piece that is no longer made.
So be VERY careful what you do with the projector and broken lamps and how you clean it.
Whatever that dibree gets on, it will ruin it, and not like right away, it will happen of time as it settles in and cuts away slowly but surely.

Dave, thank you for your info

I was lucky that almost nothing came out of the bulb itself, it was almost all contained within the bulb, except a couple very small pieces of glass. My projector also is located directly over our first row of seats (main seats for wife & I to watch from)

I also think part of the damage may have come from mercury/glass dust being inside the pj,
and then being pushed out of the vent from the exhaust and down onto the seat.
After the bulb exploded, I did take down the pj and cleaned it out the best I could without taking it apart.
I knew there was still some dust and such inside, but never thought much of it.
I mean the PJ itself is fine, and nothing inside of it was damaged, but I'm talking about a tiny fine bit of dust,
and I think just that was enough to eat away at the seat's covering over a period of time.

It's very strange to look at the seat now. Both seats to the left and right of it are almost pristine condition,
but the seat right under the PJ looks like someone poured acid all over it and just cracked and peeling off.

Thumbs up Received new projector bulb

JVC-RS-40 Lamp 'exploded'...

I placed my bulb order with Susan at Mendtronix in Poway, CA (north of San Diego) on Monday, Aug 15th about 10am. I received my bulb today, Thursday, Aug 18th at 1pm. The bulb came DHL, it was mailed from Taiwan. I put the new bulb in and WOW it is so much brighter than what I have been watching. I checked and found out I had 1498 hours on the original bulb that came with the projector in 2011. I have reset the 'lamp time' setting. Time will tell if this is a good replacement bulb.

FYI: Mendtronix is the official vendor for JVC repairs. They sell the JVC OEM bulb for $495 with a 90 day warranty, the Mendtronix Cobalt Lamp Assembly with OEM bulb and new housing was $189 and has a 200 day warranty.
Chris Albert and stumlad like this.

Thanks Ron, great info as it's hard to know what non-JVC lamps/housing to buy and not risk damage or a degraded image. Keep us posted how it goes!

As discusseded in the x30 thread, the Philips bare bulbs are a "steal" at ~$65.
