RS2/ PRO-FPJ1 Owners: Setup Discussion Thread - Page 131

That said, I'll reiterate what I've said many times before. I have no problem with the image brightness in my theater. Having total light control and being somewhat sensitive to bright light makes for a pleasing experience to me. I've had a ton of parties in my theater and never have had a complaint about the picture being too dim. To each his own though, right?



I only asked if you were doing anything about your lumens being they seem to be really dim. A lot of people saw mine to and said wow! They didn't see the loss of detail or the punch it use to be.

But I knew. And it wasn't right. I invested in calibration equipment and the time to be able to calibrate it. And I expect it to be right and JVC has a two year warranty they put behind it. You could be suffering from a damaged optical block like mine and the difference might be enough to say wow, I didn't know.

If you can live with light output that low, go for it. To each his own, Right?

You seem a little defensive...

Anyone?

No it will not..

Thanks,

Guess I have to get one from Australia now. Not very good for a 3 year old projector.

Hey guys,

In my setup I have a JVC RS2 plugged into a UPS (uninterrupted Power Supply)
then plugged in the power socket installed inside my roof.

Last night I had a power cut. One of those annoying ones, just a second.
Now my player, AVR, Power Amp and conditioner turned off and then back on.
No worries there. All okay.
On my projector. The UPS was suppose to turn to battery backup so that if the
power was permanently off I could power it down properly. Saving the lamp.
What happened in reality was the UPS just turned itself completely off.
No power or battery power. Useless.
It took me 25 minutes to get up in the roof turn it back On. Find out
the battery was fully charged and could have given me power.
So it was a complete waste of time. Actually it was more of a problem.
If it wasn't there I could have just turned the projector back On and it
would only have missed out on a few seconds of fan.

I got a few questions for you guys.

Is a UPS necessary?
Could I just use a decent power conditioner? I have a spare one.
I figured if it is a small power cut. I can just turn the projector back
On immediately. That shouldn't effect the lamp in such a small time.
If I had a long power cut. Couldn't I just open the Lamp housing and use
a hand held fan to cool it down for a couple of minutes?
It is basically what the projector does when it shuts down anyway.

What do you guys think?

Thanks in advance.

Double check the connection...... many UPS units have both surge protection and protection with battery. It may also depend on the line-battery switching time... I have seen the projector turn off with a power surge that causes a momentary switch to battery power...

Thanks Glen,

Your input is always appreciated.
However I'm not following what you are saying.
I get that the UPS may be plugged in a non-battery backup terminal.
I will check. I may have made that mistake.
However are you saying that you have seen a projector turn off
plugged into one correctly? I understand the idea of switching
might not be fast enough.

Mine was completely useless. It didn't switch to battery.
I heard it beep once. Meaning power is cut and it has switched
to battery. However when I got in the roof it was just completely
turned off. No display, No beeping, nothing. I had to hold power button
down for 4 seconds to power back up. Then it said everything was okay
and the battery was fully charged.
I think the power cut. It turned to battery. Then power came back on
immediately and then it threw a wobbly and shut itself off. A waste
of space.

What about my idea of taking it out of the chain and just use a
spare power conditioner? I have real good Tripp lite one doing
nothing. That would have been better last night.
If there is a big power cut I could open the lamp cover. Not remove
but cool down by using one of those battery operated fans.

What do you think?

Ta Dono

Yes, that has happened to mine.... Projector was on and when the amps turned on, the power surge caused toe UPS to try to switch to battery, the projector shut off........


you can always test by unplugging.... it should switch to battery and stay on battery. I don't know if you have any configuration options with it....


You could just use surge protection.... I have had my RS2 power off suddenly with no fan and there was never any issue with the bulb.... over 2K hours on one and it still works

Just in case it happens again, in my experience, you did the right thing by not powering your PJ back up right away. It is better at that point to let the bulb cool by itself or to put a small external fan blowing on the PJ rather then turn the PJ back on while the bulb is still hot. I did that once in the start of my PJ life and fritzed the bulb pretty good.

As far as a UPS -- what model are you using? I was told that for a PJ you want a UPS that puts out a true sine wave -- not sure of the science behind this. I am using an APC Smart UPS 1000 that is supposed to do so. I do not claim to know much about this, but that is what I was told. Maybe some of the bigger brains on the forum can comment on this. Not sure if this would have mattered in your situation anyway, but thought you might want to check it out.

I have had several brown outs and such -- Hawaii electric don't ya know -- and i have never had a problem.

Hope this helps.

Hey thanks guys,

I have decided to just use the Power Conditioner that has Surge protection also. Power surges haven't been that common where I live. I've only had two power cuts while watching a movie since Jan 2008.

I was unaware you can cook the lamp if you start up imediately. How long should I give it to cool down and start up again?

If it is a short power surge and the projector shuts off I'm going to open the cover and put a battery operated fan on it for 2 minutes, then let it cool for a further 10 minutes with the cover open. Re-install cover and then power On.

If it is a long power outage. I'm going to do the above but obviously not turn it back on.

Does that sound okay?

Thanks for the advice.

Tried to sell my RS2 that I just got back from JVC warranty repair in McAllen, TX. JVC says it's fine and I have to accept it may not be able to push the lumens I'd like on my 119" screen.

It had 5 month's left on the according to JVC, transferable warranty, Couldn't find anything in the manual (I had to call them twice and get a managers name), I have two new bulbs and a chief mount all for $2100 and not one bidder at the $1799 starting offer.

I had 10 watchers and I figure it must of been ten RS2 owners looking to see what they thought they might be able to sell theirs for.

If it wasn't for the warranty, I'd feel a little sheepish selling it. JVC says it checks out fine and I thought that would of added some sense of confidence.

And I don't know if the bulb issue is an issue? I'm not getting readings I once got when I first got it back a year ago. Cold I have bulbs made at the same place the RS50 bunch is complaining about and then what about JVC saying it's fine? Meeting minimum specs

My 119" screen should be okay but I'm getting barely in the high 6's now at high power.

Thoughts?

I'm thinking my bulb is starting to go. It only has 490 hours on it but I've had the projector about 2 years and 4 months. Just tonight about an hour in the movie picture would get brighter for about 10 seconds and get slightly dimmer for about 10 seconds and then back and forth. I then put the lamp in high power mode and it quit doing that. After leaving it high power for about a 1/2 hour I then returned it back to normal mode (which is where it's always been) and the flicker didn't come back).

Is this a sign the bulb is going?

I plan on upgrading with the next model but it seems I'll likely have to get a new bulb unfortunately.

JVC called yesterday and seems to be offering a trade for my troubled RS2. The trouble is do I really want to trade for the RS40 or especially the RS50 with the reported lumen issues their having? There not a happy bunch over there. According to JVC, there are no issues. The RS40 and RS50 use the same opticle blocks and lamp.

IF JVC says they will offer me a RS40 and even want a few duckets on the side, I will probably do that and hope for the better.

Now IF JVC does this, I might have a new original new JVC bulb I'd let go cheap. I'd have no use for it.

My RS2 is sitting at 225 lumen in high with 19 hrs and its only to go down from there.

Have I become a lumen junkie



I'll keep you posted.

Have you done this?

Hey Guys,

I went to go and buy one of the new JVC 3D projectors to replace my Cineversum Blackwing 3 (JVC RS2).
I didn't, because I wasn't impressed.

I arranged for a store to give me a dark room to myself for the morning. I went in on a Tuesday morning so
I had it to myself. I was looking at the RS50 (I think) 50,000:1 contrast 3D projector.
So I spent the first hour calibrating. Setting up the blu-ray player (Cambridge blu-ray) and then the projector
using Spears and Munsil calibration disc.
First thing I noticed was that the projector had a darker black level. Good.
Then after doing some 2D viewing I noticed it was very dim. I played around with the Lens settings
and opened it right up. It was still very dim.
I noticed no difference between my projector at 30,000:1 and this at 50,000:1. So not good.
The new projector was very dim. This projector had 150 hours on the lamp. Mine has 550 hours
on it's second lamp.

I then thought I would give it a go at what it is built for. 3D.
Holy Crap I hated it. Watched Avatar 3D. There was crosstalk everywhere. Blurred backgrounds
and faces looked like popups.
Sure you got some great scenes, but they were very few.
I felt it was like this. Good 3D, Now 2D, Now blurred 3D, Now 2D, Now popup. You get the idea.
Watching a movie was a real mixed bag of effects and very distracting.

I ended going back to 2D and enjoying a lot more.

Anyway my impressions (remember this is my personal opinion) the new JVC 3D projector
was very similar to the RS2 for 2D. However dimmer.
3D was crap. In it's current form I would never turn it on.
On a positive the projector was quieter.

So I left not purchasing and very happy with what I already have. It was very
worthwhile.

GREAT write up Badas. JVC contacted me about my RS2 and sounds like they are going to offer me another B-stock RS something. Possibly a RS20/25 he said.

And I thought what would I do if he offered a RS40 or RS50 with whats going on in that thread. I really thought I might decline but for a RS25

Your post isn't going to be received to well when the RS40/50 bunch read it

Makes me feel my RS2 might be worth fixing one more time.

We'll see...

I was really suprised how the JVC hasn't advanced. I haven't looked at them since I got mine (2008). You see the specs and go "mine is so useless now". However when you go and look at the new ones you end up scratching your head.

I had $$$$ in my hand and ready to purchase.
I ended up leaving puzzled about the light output of the new JVC prjectors.
Pissed of about 3D and absolutely thrilled with the performance of my projector and that I was keeping my $$$.

So really a great experience.

Ta Dono

I am not an expert but I think this is the bulb arcing. People suggest that you keep the fan on high for a movie or so and then back to low. This should get rid of the light fluctuations. I dont think this is a sign of the bulb going....I hope! Good luck! Chad

Thought I was seeing light that JVC might replace my ailing RS2. (get it, light) Then I just got this:

Dave,
The service technician in Long Beach did evaluate the unit. It was low in brightness when they received it. They put a new lamp in it and it was above spec. Calibrated it fell about 100 lumens.

The brightness will fall off during the life of the lamp. That is normal.

I will be more than happy to find you a good deal on another JVC projector.

Thank you,
JVC Management


IT WAS LOW AGAIN IN OUPUT. So I get another bulb (4th one) and we skip on down the road. It had the same NEW bulb in it they put in from before! They haven't told me what minimum specs are. I thought it would be around 600 ANSI Lumen's.

I have less then 200 hours on my projector since I got.

And please, no comments about how benevolent JVC is giving me another bulb. I wasn't asking for a new current projector. But something is wrong with my output and JVC was sounding they might sway me out with another B-stock perhaps a RS20/25

Its not over yet as haven't gotten it back YET.

The RS2 that I still use quite often did the bulb flicker thing at random times with both lamps I've used in it. From what I can tell it is somewhat common. The first lamp I change around 1800 hours and it flickered for short periods of times.

But as has been posted, usually just running in high awhile makes it stop. The lamp I'm using right now has a little over 2000 hours, as I just check it to see. I gotta say that after I change the first one at 1800 hours, while of course it was brighter, it didn't make me go WOW.

I cannot tell the lumen output at this time but all I know is on a studiotek 130 106" Diagonal screen, its still makes my eyes squint when going from a dark scene to a bright scene. So, it still looks good to me when I use it.

I just been lazy about buying a new lamp at over 2,000 hours but of course I know its dimming. I have cleaned inside the lamp area a couple of times.

I like dark blacks anyway. I started to change this RS2 a few times but decided just didn't see the point of it with another JVC for now. But I also use it with a DVDO Duo.

I like bright projectors but like dark blacks better. A Mitsubishi I used awhile was brighter but I didn't like the black levels.

Still loving the picture of my FPJ-2 and honestly, see very few reasons why I should upgrade to a newer PJ... but there's always a but... lately, the focus seems to drift off and I have to refocus the projector about every other month. I can't remember having to do that for the first year I owned it (or I simply didn't pay enough attention, alternatively, with my old screen I couldn't see it as clearly). Is this normal? Anyone else seen something similar?

I have the FPJ1 (RS2 Clone) as well and if my focus has wandered a bit, it hasn't done it enough to notice. Still loving the projector and see no need to upgrade. 3D is not for me.

I am very similar to you. I changed my lamp at 1900 hours. I keep it as a spare. I noticed the new lamp was a lot brighter. However I like it dimmer also. My old lamp at 1900 hours was still bright enougth to make my eyes squint. Colour, Contrast and brightness was still acurate before changing.

I clean my lamp housing ever 100 hours. New lamp is at 600 hours. I still get carbon with every clean. The new lamp has flickered twice. Stick it on high for 2 hours (one movie) and it goes away.

Still very happy with this setup. Have no desire to go to 3D.

Ta Dono

Yeah,
Mine does it while using it. I prefer mine slightly out of focus. To hide the pixel
structure. It starts in perfect focus and then after 20 minutes moves out of
focus. When I turn off and then back on the next night it repeats the process.
Mine also moves the picture up and to the left after 20 minutes. I just position
down and to the right a little to compensate.

Ta Dono

Thanks guys! I actually forgot about posting this. I let my projector run on high for the remainder of the movie I was watching at the time and then on one more movie and it hasn't done it since.

I want to upgrade as well but kinda like you Larry I'm not going to do it until there's a significant improvement. I saw an RS40 earlier this year on a Stewart Screen about 1.1 gain and it wasn't much better than my RS2 on an HP screen.

Wher to you guys get your replacement lamps from and what is the cost? I see some selling for under $200 on Ebay but don't know if they are just a cheap knockoff.

Thanks,
Tom

What are the downsides of using lens shift? Say for instance that I wanted to lower my screen 2 or 3 inches. What does that do to the picture?
