Official JVC DLA-RS46 / DLA-X35 owners thread - Page 12

Thanks, I'll start there.

@moviefan123 - I just hooked up my new RS4810 today and noticed the high-pitched squealing/buzzing on this projector too. That's three for three JVCs that have done it. IIRC it does change pitch and/or volume depending on the format of the input signal as Kris implies, but I'll have to check to see which signals cause the squealing the most. I really never paid the noise much attention because I've heard it on three JVCs and my Sony VW60 before that, and since you can only really hear it when you're in front of the projector (since the noise seems to come out of the projector's vents), and my projector is overhead when I'm watching a movie, I never hear the noise during actual projector use.

I am only hearing it with a 1080p60 signal. If I do 1080p24 it goes away completely. You can also hear it change pitch and volume during HDMI handshakes when it hasn't figured out what it is going to show.

My friend this problem rs56.
lamp engine Exchange.
old RS46 50/60 Hz beeped
new not

This does not upgrade but downgrade.

Again, I've had three JVCs and they've all had the lamp squeaking. Why would I expect a fourth to be any different?

I seriously can't comprehend the trouble you and "your friend" are going through to exchange projectors over minor "streaking" and lamp noise issues.

IIRC this is exactly how mine behaves.

120" Grandview screen 13 feet viewing distance, I can see the character smudged poor sharpness.
Does not affect the zoom, lens shift
My opinion, this is the inside of the lens fat, oil deposition, factory error.

Mine also looks like this.

My RS4810 looks like that too. Seriously, I wouldn't sweat it.

I'm doing a quick and dirty (for now) set up of the RS46 which arrived Friday, though watching the NFL Wild Card games cut into my time quite a bit. A quick question for you DILA veterans. The white bars on the focus screen are completely white with no color fringing at all. I'm taking that to mean the panels are properly aligned and I should leave the pixel shifting control alone. Is that correct?

I built my current screen slightly curved, since I used a cheap Home Theater Brothers anamorphic lens with my previous projector. I hoped to forget that lens with the 46 and just use the lens memory, but wasn't sure the depth of focus would be great enough in the 46 to have the entire screen in sharp focus. It appears it is; on the focus screen I can get both the center of the screen and both sides to focus sharply. The lens memory function is really slick.

The Logitech Harmony database doesn't yet include the 46, so I used the RS45 settings. About the only difference I can see is that the 45 only has commands for 3 lens memories, while the 46 has 5 available.

I'm hoping to have this far enough along to watch a movie tonight.

Using the the basic settings given to me by another forum member, I watched Killer Elite last night. Wow! No buyers remourse here. I seem to get a new projector about every 5 years. Five years ago when I shopped, the LCOS projectors looked kind of soft and mushy compared to DLP--people called it "film like", but it still looked soft to me. The RS46 looks very sharp to my eyes, even when losing some pixels zooming to fill a 2.35 screen. The improvement in contrast over my previous BenQ W5000 is easily seen.

I notice that most people close down the iris a bit. The RS46 is exceptionaly bright on my unity gain accoustically transparent screen and I probably need to cut the light a bit, at least with a brand new bulb. Are most people aiming for a specific lumens level or just adjusting the iris to taste?

Hello, you can read my test of JVC X35 on this forum (it is in french) : http://www.homecinema-fr.com/

I think many just adjust to taste, though I use a Lux meter so I aim to match my 16:9 setting and 2.35:1 setting (with and without my A Lens) so I know I'm looking at 15fL for both aspect ratios. It also means I can keep a check on my lamp which is now over 80 hours and has dropped by about 2 Lux from new which is under 2%.

Great thread! I picked up an rs46 last week and I am very impressed with the 2d thus far. I was wondering what the least expensive route to 3d is. I am interested in going the RF route though, so I imagine I will need the JVC RF transmitter. What are some of the most affordable glasses options that work with the JVC RF, or is there actually another RF transmitter / glasses combo that works well that is even more affordable? Thanks for any help and suggestions.

Get the JVC RF emitter (it's around $80) and SSG-4100GB glasses (they're around $20/pair and they should work -- they work with Panasonic Bluetooth 3D TVs and the Panasonic glasses work with the JVC RF emitter).

Also, my experience is that you should strongly consider getting the updated JVC firmware (if you don't have it already) that fixes some 3D issues. The 3D performance of my RS4810 was MUCH better than the 3D performance of my pre-firmware RS46 and it's likely that the newer RS46 firmware will make it perform just like the RS4810.

X3


X30


RS46



I don't think I should accept the 'as is' performance of the RS46. My aim was to upgrade after the X30.

That is a lot more color fringing than I saw on the RS46 I installed in my HT last weekend. In fact, even right up next to the screen I could see no color fringing at all on the white characters and focusing bars the RS46 creates.

Both of the RS46s I had as well as my RS4810 have all had a bit of red fringing on the top of white Focus characters (perhaps 1/3 pixel) but I suspect this is partially due to CA from the lens shift and extreme zoom settings I'm forced to use in my set up. The focus grid is pure green so you won't see any fringing on that. In my case I sent convergence pics to both Mike at AVS and a first-line JVC tech support guy (I'm double-checking with second-tier guy later this week) and was told mine's fine. It's not perfect, but in my configuration, it probably never will be, but that's a large part of the reason I stepped up to the 4810 -- to be able to correct misconvergence!

@szepi0808 - your RS46 looks about like your X3, but if you're not happy, then return it. Your previous RS46 looked better IIRC. Just be advised that it's very likely you'll never get a projector with perfect convergence and honestly I wouldn't expect convergence to improve much between projector generations. Quite frankly, if I had an X3 and/or an X30, I wouldn't be bothering to upgrade to the RS46. I bet the improvements are minor at best. I kept my Sony VPL-VW60 for almost 5 years and I expect I'll be keeping my RS4810 about that long.

the camera sensor is going to amplify what it being seen with the eye.

is it really that bad when you stand back a few feet?

Streaking the big problem.
Second RS46 streaking and CA problem. Back to jvc Center look forward to your replies.
I would like to receive a free sreaking rs46.

Unfortunately it is. Streaking is clearly visible even from veiwing distance (13 feet). Especially with high contrast scenes or when subtitle is on. Moreover sharpness suffers the most due to streaking.

I would say that you might be able to lower the vertical red pixel adjustment one click to see if this resolves the issue. Of course it might not be consistent across the whole screen, but I tend to preference getting the centre at the best and accept a little misconvergence at the sides.

FWIW My horizontal convergence is very good across the whole screen, the vertical convergence is better with the red shifted one click to the right as this now has the left and middle just about spot on, with a small amount of red bled to the right side. Blue vertical is a little to the left on the left side of the screen, perfect in the middle, then moves to the right on the right side of the screen. IIUIC blue has the least effect on the image sharpness, but at least it's equalised across the screen.

I don't know if my convergence helps with the 'streaking' issue as I checked mine at the weekend and there really is non to speak of unless my nose is on the screen and even then it's hard to see (I don't think it would photograph well, so I didn't bother). This is with the X35 level with the top of the screen, so some downwards lens shift applied (no horizontal).

See you rs46on the streaking problem?

Weird. I have streaking on my RS4810 also but I honestly can't see it at all once I get more than 2-3 feet from the screen. It might be a little more severe than what my RS46 had but I also have the eshift device in the light path now so who knows what that's adding, plus I've opened up my iris a little compared to my RS46 so the image is a little brighter. Bottom line is that all of my JVCs have had it and based on anecdotal evidence it seems present to some degree in all of 'em. I think a combination of throw, zoom, focus, lens shift, and screen material might be exacerbating the effect. I'll be very surprised if your next X35 doesn't do the same thing as your two previous ones.

This is a manufacturing problem to me if two projectors with serial numbers fairly close to each other are faulty.
If they cannot provide me with a good one I'll return to an X30 for sure.

Hi All,

I have just installed the 46 in my room this past Friday and after watching 5 or 6 movies I am noticing flickering on low lamp mode if I bump to high lamp it goes away but the thing I dont understand is when I go back to low lamp the flicker is gone for about 10 or 15 minutes then it slowly comes back. I have a completely light controled room and the image looks great and is bright but it just flickers. Do I have a bad lamp or something more serious?

Thanks

I feel like we've flogged this dead horse enough but I did look at the streaking again on my 4810 so I'll give you some more feedback. For one, at my current lens settings, the streaking coming off of white letters is almost all very, very faint blue in color. It's possible that explains why it's so tough for me to see. If I zoom the image out so it gets smaller, then the white streaks become more obvious but the blue streaks diminish.

Anyway, my observations cause me to believe that there's a lot of variables at play here that cause the streaking's intensity and color. Based on the fact that so many people have reported seeing it (check the RS40, RS45 and RS55 threads for many more examples) even in prior generation projectors, I feel it's simply a design limitation that causes this to arise. There's likely some projector variance as well that causes its appearance to vary in intensity and color depending on lens settings, aperture settings, screen fabric, throw distance, screen size, and the like. However, I think that most JVC projectors suffer from this phenomenon to some extent, but individual projector settings might cause it be more or less apparent.

I can just barely (and I mean barely) make it out at three feet from my screen, only in sharp-edged white-on-black text, and only because I know where to look. Beyond that, it's invisible. If this reared its ugly head in more viewing situations or at distances more than three feet away, I could see it being annoying, but I think most folks have accepted it because they simply can't see it unless they're right up against the screen.
