post #4051 of 4219
Ok, I have decided to order a new bulb. Anyone know a coupon code that works?

Or can someone recommend a non-factory bulb?

Thanks!

The code JVCPROMODP1712 did not work now. frown.gif

I retrofit the new OSRAM bulb into the original JVC bulb housing. significant picture improvement over the OEM bulb.
post #4053 of 4219
How difficult is this "retrofit" process? And how much does the new OSRAM lamp cost?
post #4054 of 4219
Was the picture improved from the OSRAM lamp because it is brighter?
post #4055 of 4219
You can find the osram online for about 100 bucks. I got mine from replacementlightbulbs .com. Interlight is even cheaper, but never tried them before. Its easy to retrofit. Just wear some latex gloves (to avoid getting oil on the bulb). Other than that, its just removing a couple screws. My osram bulb has 2000 hours on it now, and still works fine. When it was new it was better than my original bulb imo. And miles better than the generics I tried from places like electrified.com
post #4056 of 4219
Is this the lamp I would want to order then: http://www.replacementlightbulbs.com/lamp69471.html
post #4057 of 4219
That is the same p/n Glen mentioned a while back (69471), so I would say yes.
post #4058 of 4219
Thanks. I placed the order this morning- so hopefully I have the skills necessary to retrofit this into my existing cage.
post #4059 of 4219
please let us know how it goes! time to delivery, packaging, how easy it was to do the swap...

it would be helpful to have that information logged here. I'm thinking of doing it too!

thanks.
post #4060 of 4219
Will do! If I remember, I'll try to take photos during the process.

From what I'm told, I need to cut the wires connected to my existing lamp, and then attach new terminals to re-connect to the new lamp. Then it's just a few screws to uninstall-reinstall the new lamps.

It always sounds that easy though. We'll see how it goes. I ordered through "replacementlightbulbs dot com" for the record.

After a couple years ago getting a supposedly JVC factory bulb from Electrified.com and finding it some generic knockoff that was very difficult to install then had a burning smell was 50% brightness I swore I'd never ever screw around with a non-genuine JVC replacement. Since that time I've replaced bulb twice with JVC genuine bulb and has worked perfectly.

Now I'm at 1300 hours and starting to think about replacement here in 3-6 months. I'd extremely skeptical about this OSRAM thing but would like to see a replacement pics or some more stories of people that have used them.

Also I have never cleaned the inside of my RS2 and am "afraid" to do it. I've had it since April 2008, opinions?

Oooohhhh yes, most definitely you should clean the prism and the lamp glass. The process is in this thread and believe me it makes a big difference. There is so much soot on the prism and on the lamp glass... Follow the process and you will see how much soot you clean up off. I clean mine every 2 months and recalibrate the unit and it is extending the life of the RS2. I bought a spare lamp with that coupon code sometime back and still haven't used it, because cleaning it is making it much the currently installed lamp last longer. I currently have an 2nd lamp installed, original JVC, with about 570hour, kind of wish I didn't get the new lamp, due to the 2013 JVC's are coming out and I've decided after years of the faithful RS2 it's time to upgrade. If seen some of the newer models after the RS2 just didn't warrant an upgrade, however at CEDIA this I saw the new line up and I new it was the right time to upgrade. Anyone in the market for an RS2 with extra lamp?
post #4063 of 4219
Looking forward to your pics of the install. I plan on doing the same but would like to see some step by steps instructions and photos. I am awful at this kind of thing and thinking of opening it up is already making me nervous!

I most likely really need to clean mine too. I have owned it for probably 4+ years!

I would normally side with you on this, that you shouldn't replace something spec'd from the manufacturer with an aftermarket DIY solution. However, there is something to be said for the markup involved for something to be branded OEM, and the little effort it actually takes to replace the lamp inside the existing cage.

Also, the OSRAM lamps have proven to be a better solution, with more light output and more accurate spectrum from what I'm told. The 2 advocates on this thread alone are both ISF calibration experts.

As I said look through this thread and it will detail how to clean the soot from the prism and lamp. It is very simple, all you do is pull the lamp out and clean the lamp with and alcohol swab and do the same with the prism ( it where the the lamp sits). There are pics of the clean.
post #4066 of 4219
WOW. That was easier than expected!

New lamp installed and it looks great! Writeup and photos to follow soon. If anyone wants to get this project started, I ordered the lamp from the link above. It showed up in 2 days.
post #4067 of 4219
Toddious please writeup and photo. I have a LOT of interest in this! Greatly appreciated!

OSRAM Lamp Replacement Instructions:
The installation of the lamp is very straightforward, and requires some basic tools, and a few items you may need to source from hardware store.
Tools:
-Latex Gloves
-Phillips Screwdriver
-Wire Cutters
-Wire Strippers
-Wire Crimpers

Supplies:
- OSRAM 69471 Lamp
- 22-18 gauge Metal Ring Terminals (or remove nylon- see below)
- (2) 3mmx5mm Screws OR (2) 3mmx6mm Screws
- (2) 3mm Washers/Lock Washers
- Isopropyl Alcohol- Rubbing Alcohol (Optional)

Directions:
Step 1:
PUT ON YOUR GLOVES! You do not want to get oils from your skin on the lamp.

Step 2:
Open the lamp door by removing the single phillips screw from the lamp door (labeled with CAUTION/ATTENTION sticker), and remove the lamp by removing 2 phillips screws on either side of the lamp.
Photobucket

Step 2:
Remove the 4 Screws holding the cage together and remove the back cover. Then remove the 2 mounting screws from the cage, as well as the 2 metal retainer clips.
Photobucket

Photobucket

Photobucket

Step 3:
The original factory wires are soldered to the lamp connectors, so you will need to cut the wire coming from the connector as close to the lamp as you can, then remove the old lamp from the cage (it is held in with a little pressure, but will pull right out).

Step 4a:
You will need to have metal ring terminals, which I couldn't find at Home Depot, so I purchased regular nylon 22/18 gauge crimp terminals, and just cut off the nylon to expose the bare metal.
Photobucket

Step 4b:
Strip back the ends of the wires about 1/4" and crimp on the metal ring terminals
Photobucket

Step 5:
Install the new lamp back into the cage
NOTE: the lamp is labeled TOP on one end, but the wires will not reach the connector locations without being extended. The bulb will technically be installed upside-down inside the cage, but I'm not particularly worried about this, as it will always be upside-down/right-side-up depending on how you have the projector mounted. That being said, it would not be difficult to extend the wires by soldering or using all metal crimps and some 14g wire.

Step 6:
Screw the wires to the new lamp using 3mmx5mm/3mmx6mm screws and washers. The shorter wire will connect to the terminal that has a wire lead to the center of the bulb. I used both a washer and a lock washer, so I had 3mmx6mm screws. If you only use a single washer, just be careful to make sure the screw does not go all the way through the terminal to the bulb.
Photobucket

Photobucket

Photobucket

Step 7:
Reassemble the cage by installing the metal retainer clips, mounting screws, and back cover.

Step 8:
Take advantage of this opportunity to CLEAN YOUR PRISM! If you look straight in the opening where you're about to shove your lamp, you will see the glass prism. Take Isopropyl alcohol wipes, or use a microfiber wet with isopropyl alcohol, and clean the prism. Then wipe down with a clean microfiber or lens cleaner. I didn't think mine looked too bad until I saw what was on the cloth

Photobucket

Step 9:
Once the prism has dried, reinstall the lamp using the 2 mounting screws, then screw on the lamp door.

Step 10:
Reset your lamp counter, and have fun re-calibrating the bright and beautiful picture!

I will just note that at least for me, those steps with the crimpers and terminals were unnecessary. My old bulb had identical terminals, they werent soldered like yours was. So all I had to do was unscrew it. Still even if you have to do that step it is something anyone can do.
post #4070 of 4219
Thanks for the pics and instructions. Looks a little complicated for me but am going to try it.

How do you like the OSRAM lamp compared to the factory?

That's interesting. I was warned that I would need to cut the original wires, and my lamp is the original from the factory.

Was your lamp ever replaced? Or what year did you purchase your projector? Also, mine is a PRO-FPJ1 so I'm not sure if that matters.

Regardless, it's a simple process...

No problem, hopefully this will help a few others save some money. I think once you start, you'll realize it's a lot easier than you thought. It's very straightforward and didn't take me more than 20 minutes total.

The new OSRAM lamp looks awesome! Granted, my original lamp has needed to be replaced for a while so my "Reference" at this point is the underpowered image I've been watching for the past year. However, the colors look stunning (red seemed a little strong, so I've dialed it back a little), and I'm back to running in 2.4 gamma, with brightness at around +3 and in low-lamp mode- so I'm getting some very good contrast and black levels.
post #4073 of 4219
I saved all of my lamp housings, so I have 4 of them total so I can prep the lamp prior to my existing needing to be replaced.

The link in post #4056 is definately the correct one? It doesn't reference anything that would make it seem to be compatible. How much was shipping out of curiosity?

At that price if the lamp is as good as the JVC OEM I'll be very happy but quality and reliability is of most importance to me because we don't replace lamps that often (1200 hours in 12 months) so we replace probably every 18 months or so.

Yes, the link in 4056 is what I ordered and the correct part. Shipping was only a few dollars so about $104 for the lamp, and about $4 between the gloves and crimps. It is the same specs as the original lamp, and the price is definitely nice!

I can't speak for long term reliability as mine is new, but I can tell you the picture looks great and I haven't noticed any flicker.

Mine is a plain RS 2, it was the original lamp. As for reliability, my OSRAM lamp has 2200 hours on it now. Still works. Never had much of a flicker. (my last bulb eventually did) Debating buying another replacement now.

Good time to consider a replacement projector since preorder pricing is available right now.

Well I'm definitely glad I came back to peruse this thread.

I was going to look for recommendations on where to buy an OEM replacement bulb, but the OSRAM sure as heck is tempting to give a try.
post #4078 of 4219
Toddious, good job putting up the pictures and detail description on how to replace just the lamp. OK, I admit I was apparently to lazy to do all that back in August, 2011 when I finally figured out what bulb would work in a RS1/2. But I must say that I didn't really think there was all that much interest in people doing it, most want the original JVC housing and all. True, I did get quite a few PM's over time asking some questions about replacing just the lamp, after reading the links and specs on the lamp that I posted.


Still, the fact is I had asked in not only AVS but other forums going back to the RS1 if anyone knew who built the lamp for JVC. Maybe somebody knew but nobody ever told me, and certainly not the Specs needed to find a bare lamp. Well, I did hear there wasn't a aftermarket one available a few times. But as I've said before, Osram or Philips aren't after market other than the fact they offer the same lamps they sell to the companies through distributors, without the housing. Yet they don't tell which lamp fits what, they has to be crossed and matches by Specs. Mostly for rear projection market though, since it was much larger in the past.


That's not always easy or possible with front projection, but not impossible either. The thing is that its normal for the company building the lamp not to put any specs on the OEM lamps sent to whatever company they build it for. Like all the JVC lamps I've seen for the RS1/2 mostly just have HSCR on them, which is Iwasaki and that is who builds them. Iwasaki rarely offers bare lamps.


Osram and Philips do however and once someone knows the specs of the lamp, then good chance they can find a bare lamp to replace it. True that these days way to many copies and companies building lamps that are unknown and not very good quality. Plus some of the generic housings can smell pretty bad. But most of those come with housings and aren't bare lamps.


So, when I finally did manage to figure out the specs and saw that Philips and Osram built one, I knew that was what I wanted to use. Sorry JVC but that Iwasaki lamp isn't all that great IMO. Some might not agree and that is fine. Its about impossible now to find the Philips in the USA but getting a Osram is easy. But Philips is the one I dealt with myself at the first.


Someone recently asked how do they know that is the correct lamp in that link for replacementlightbubs. Well, its the specs and that is just one place that sells them but appears to be good. But those numbers, 200/1.0 P21.5 is what you need to know. The "P" means parabolic refector and the 21.5 is the reflector size. The 1.0 is the arc length. 200 of course is the wattage. It's a 5KV ignition because there isn't a "h" at the end. The P-VIP simply means its a Osram, like UHP would mean its Philips. Actually the real Osram number has "a" after the 21.5 and that just means aftermarket.


Also I've never heard that "TOP" printed on the lamps means anything regarding which way to turn it in the housing. These lamps have air gaps and have to be turned a certain way because of that, but in this case you cannot turn it the wrong way because its not square. But no need to turn it and make the wires longer just because of the word TOP. Some lamps with air gaps are square though and then have to pay attention on which way to turn it. Also I've never seen a JVC Iwasaki lamp come with plug wires that has screws on the end. That sounds like a after market unless JVC changed who builds them.


Anyway, its been a long time since I read this thread and I just happen to be on AVS today and saw all those pictures. Plus I haven't been on AVS as much since the change it appears. But hope the information I posted in the past help some to save money with a better lamp. and maybe more read it than I thought, and went on to use the information. But it does appear the people that have tried it agree its a better way to go considering the price and is generally brighter and less likely to flicker.

Larry thank you very much for this information. I'm considering lamp replacement it'll be my 5th lamp all 4 previous lamps were JVC Geniune after a run in with one knock off that I didn't think wasn't a genuine lamp didn't fit properly and smelled and was dimmer than a lamp with 2k hours. Having all these extra lamp housings make it that much easier of a decision if these replacement OSRAM lamps are of equal or better quality. I am still wondering about cleaning of the prism and what is the best way exactly to do so, is it just one flat surface inside? My RS2 is 4.5 years old and I've never cleaned it so I'm just worried I might screw something up.

BTW: Does anyone know if these projectors last a really long time, it is my first home theater projector and I'm curious if anything wears out after a certain period of time. Seems the local repair centers charge quite a bit to repair these. I know that my old Samsung DLP TV had the DLP chip go bad and a color wheel go bad if it wasn't under warranty it was going to cost more than it was worth.

Some of the generic housings do have a really strong smell, but any new one probably has a little smell for awhile. Whatever you purchased was some kind of copy from someone, if it was dimmer. Osram or Philips are not dimmer, and should be some brighter. Unless defective of course. The prism is just a flat surface and its been awhile since I cleaned one but I just used a microfiber cloth. There are detailed pictures of that in another JVC thread somewhere here on AVS. The deposit build up appeared to be worse on that model maybe.

Always hard to set the life of electronics, especially with the heat of a lamp. But the RS1 and 2 seem to be build well and I haven't seen a lot of people talking about having problems. Seems to me like the later versions have more complaints. I think some power supplies have gone out but that's not so expensive really but it depends on who is doing it though. The RS2 I use sometimes has around 12000 hours on it believe and never shown a sign of a problem.
