Official JVC RS-50 Owner's Thread - Page 133

post #3961 of 4215
Thanks Zombie10k and henrich3 for your help.

I think I'm trying to find a way to convert my RS60 to a RS40, thereby gaining the advantages both. It's hard to imagine that the addition of one additional iris, and an in/out green filter, and a CMS circuit board that can be switched off, would result in a substantial loss of D65 output. All the major components: lamp, ballast, optics, and cooling, are the same between the RS40 and the RS50/60.

Roger - Some of the early speculation is that the panels in the 50/60 are being driven differently than the RS40.

The reasoning behind this is that when we turn color profile=off, RS50/RS60 owners reported a noticeable shift towards green/blue. The RS40 does not have the same settings (color profile=off) but it does have a similar setting which RS40 owners do not report the heavy shift towards green/blue.

This was also discussed when an RS50 owner swapped his projector for an RS40 and noted a 30%+ difference in brightness between the two models. Others have validated this with different results, but in most cases, the RS40 was brighter with everything else being as equal as possible.

I asked a JVC field engineer this question back in March, and he didn't have an exact answer, but the CMS was mentioned.

For some folks, this is a big deal because the marketing material clearly stated that the 2011 models were 50% brighter than the previous models. A few folks even purchased large screens (up to 14 feet is now possible) based on the marketing material which has been quietly removed from the JVC US website. (likely because of the complaints from different owners in this thread)

Well, according to the wiring diagram, the CMS board can be bypassed by changing a couple of cable connections. I'll give moral support to anybody who wants to try it.

The parts list shows a separate part number for the RS40 driver board, but I'm not sure that means anything since there's a separate number for the lamp as well.

I've just posted some news about the planned JVC 2012 projectors on the CEDIA thread (HERE).

Larry - Hi, I received a reply from the fellow at the company who sells the replacement lamp.

"Hello Jason,

Thank you for your email.

The lamp we sell for this model is manufactured and branded by Philips. It reads the following specs on the lamp 360/90 200w 1.0. We actually started selling this lamp recently and haven't had any issues up to date.

If you have any other questions or concerns please do not hesitate to contact me."


I asked him to email a photo of the lamp and it will guarantee a sale from me. For only $250, I have no problem buying it and giving it a try. I'll even save the new 5 series until it arrives so I can directly compare factory vs. 'after market'.

I'd really like to know if it's a Philips. I don't want to buy a 2nd hand reject from the OEM - whoever that is!

I wonder if he's got the right lamp. The OEM Lamp is 220W but he says the Phillips is 200W.

The original JVC lamp in the current generation RS40/50/60 projectors is spec'ed at 220 watts while this Philips replacement they are offering appears to be spec'ed at 200 watts. If this is a Philips lamp and if it maintains it brightness over a longer number of hours than the one JVC is using, then the lower wattage rating may not be an issue. As I recall the previous generation of JVC projectors used 200 watt lamps from Philips. Kind of mades me wonder if that is what they are selling. If they do send you a photo showing the markings, then I suggest we check that against the Philips lamps being sold for the earlier model JVC projectors.
post #3968 of 4215
Geoff & Ron, thanks for pointing that out. I should have remembered the factory is spec'd @ 220W.

This guy can make a quick sale if he just sends a photo so we can try to identify the lamp compared to the factory model.

I am willing to take one for the team if it's truly made by Philips.
post #3969 of 4215
I'd be leery of any Phillips branded lamp being a replacement for this years OEM lamp. This would be nice but wouldn't Phillips want advertise (and spec) it?
post #3970 of 4215
Yah and if the Philips lamp is only 200 watts....that means no 13' foot screen for Jason.

i think my lamp is down to ~80 watts.. I'll take the 200!

what's wasting $250 for the sake of science. you guys know your curious!!

Curious, yes, dubious, definitely.
There is more to the lamp than just having it fit in the holder. Asides from the obvious electrical drive which may not be the same for all lamps there is the focal point of the lamp to consider. Each lamp has a built in reflector and this is shaped to focus light output at a specific focal point which may vary between different models of projectors. It may not hurt to try it but I remain skeptical that just one vendor has access to a phillips branded replacement for the bare lamp.
post #3974 of 4215
so does this look like the older RS25/RS35 lamp for those that are familiar with that model lamp?

I can't find any information on the various markings of the lamp. It's hard to tell if the shape is even the same.








post #3975 of 4215
I may be missing something but it doesn't look like there are metal tabs for the mounting screws.....can the metal plate surrounding the JVC lamp come off if the lamp is removed?

Hi Jason,

Thanks for the photos.

Please ask your contact to send you a photo of their JVC BHL-5010-S lamp or the JVC DLA-RS20 replacement lamp.

The pricing is identical and I suspect they are showing you a photo of the lamp for the earlier JVC models for which Philips was the original lamp.

Larry

An update regarding my replacement lamp that I was told was on backorder till August 15. It arrived today, but I have not opened it. I'll let you all know what number is on it. So If anyone was going to return their lamp to JVC for replacement, they must have them back in stock.
post #3978 of 4215
can anyone tell me how to adjust my rs50 to get the blackest, black levels? I know its not going to match my old crt, but I would like to get as close as possible. Does closing the lens apature and adjusting the gamma help? are there any specific modes I should also set?
post #3979 of 4215
My replacement lamp just arrived. Both the old (dead) lamp and the replacement are 5-series bulbs. I had forgotten just how bright this projector is with a new bulb. Really impressive - hope this bulb works for more than the 550 hours of the dead bulb.

I agree Geof. Sounds too good to be true but as long as you get a guarantee of compatibility from your seller Jason than you should be safe for a refund if it doesn't work.

I wouldn't mind spending it if I knew it was a direct fit, but all indications so far are showing these guys are confusing the 2010 and 2011 lamps. I sent them back several photos of my lamp to compare, but it looks like it might be a dead end.

Jim - The room is your #1 priority then use AVS709 disc to calibrate white balance, then most here have been round -7 on the iris to start (hell some like it all the way down, but I suspect only for the first 100 hours or so!)

The standard profile is closest to rec709 and I prefer gamma 'A' for 2.3 without a pro calibration.
post #3983 of 4215
Does anyone know what the acceptable convergence is for the RS50, before it can be serviced/replaced? What is the main issue with bad convergence if you don't notice the colour fringing from your seating position? Does it still effect overall picture quality?

Also, JVC is sending my projector back with 2 bulbs. I hope these last more then a few months each this time!

JVC Canada was shocked to hear all the negativity and bulb problems with these projectors and they seem to care more about the problem then the US. I forwarded them a bunch of links and they are reading these forums now. They are also forwarding these issues to JVC Japan, and they promised to follow up. So, Jason and friends. Keep up the good work

I'm sure they'll be told to "tone down the sympathy" and not to respond. That's what they'll have to do to fall in line with JVC official policy regarding these projectors. This "head in the sand" customer service is a shocking turn of events for JVC and I'll never buy another JVC product. There are too many other choices.

BTW, I didn't even get screwed by them. I still have an RS20. I just find their wall of silence to be outrageous. Clearly JVC reps who have posted in this forum have been given marching orders to abandon you.

Seems like for those really really wanting their money back for 50s and 60s they purchased, due to all the CMS issues, lamp issues and misleading advertising regarding lumens, since removed from web site, could take them to small claims court for price of the projector. If they can organize the information coherently for the judge so his eyes don't glaze over. Especially if purchased to be able to use on the 14 foot screens. Why would a judge find for JVC? Would JVC even show up?

If they don't show up you get a default judgement. You win. I think this is a great idea.

And then, how do you collect? Maybe it would be like that couple who sued B of A for foreclosing on them when they didn't even have a loan! They showed up at the B of A office with a moving van, a couple of big dudes and a Sheriff's deputy! They proceeded to clean 'em out. GREAT story!

So you sue in small claims, get a record of judgement, try to collect, fail, get the sheriff involved and go raid one of their offices. THAT would get their attention!

Has anyone been able to make this combination work for Bluray 3d Playback? For some reason, when I play a 3d movie, it will not play in 3d mode. I enable 3d mode in TMT5 but nothing happens. Movie is still in 2d mode.

Anything I should check for in terms of settings on my HTPC?

Hi, I've had this exact setup in place since October, 2010. Windows 7, 64bit (also worked fine with my 32bit setup), Nvidia GT430 and TMT5 / PowerDVD10.

Do you have the Nvidia 3D vision 'kit' which includes the Nvidia IR transmitter and 3D glasses? In the last few months of updates, Nvidia is 'requiring' this USB dongle to use HDMI 1.4 devices in 3D, otherwise you have to Ante up about $40 for extra Nvidia software to allow 3D playback to your projector.

Please post more about your setup, it's likely going to be a straightforward fix once I can see what's going on with your configuration.

I returned mine with no quibbles. I simply pointed out that the projector did not perform as advertised and was therefore unfit for purpose = full refund under UK consumer law...

I still hope that JVC can continue to innovate and deliver projectors we want but I won't blind buy again, based on advertising specs, as I did with this projector.
post #3990 of 4215
I'm not looking to return mine but others seem to be having a much tougher time that would like to do that. I guess it's the luck of the draw whom you're dealing with in their organization, and your UK law is a good help. Glad to hear your situation worked out.
