JVC HD-ILA Microdisplay Rear Projo HDTV

[rgriffin25]

We are beginning to get our 2005 model TVs in stock. To my suprise there is a yet another "new" technology available. I have yet to spend a lot of time with the new set I can say the picture looks very good on both HD and analog signals. Here is a link to a article that gives a brief discription of how it works.

JVC HD-ILA (http://www.jvc.com/main.jsp)

D-ILA is JVC's implementation of LCoS. Remember Intel claimed that they would be able to drive the price of 50" LCoS tvs down to under $1800 by the end of the year? Doesn't look like that's going to happen any time soon, given the JVC clocks in at 3 times that.

[rgriffin25]

Their retail price is about $1500 higher than what we are selling it for. So I imagine the cost has come down since they released their prices. I am happy there are so many choices in the market now. The prices on our DLP sets have dropped almost $600 in the last few months. :)

Hello, I am new here. any recommendation for a rear projector for my HT with YAMAHA RX v 1400 and YAMAHA Boxen NS 1000

Next questions, what DVDs do u prefer

Thanks

"from Mexico" - we'd love to answer your question, but it's more appropriate to start your own thread rather than what we call "hijack" another that is dealing with a different topic.

The main reason for this is that no-one will come here to answer your question - they are assuming this is a thread about JVC's new HD-ILA TV (based on its title).

I've been a closet fan of LCoS since I read about how the technology worked. All the benefits of LCD without the visible pixel gaps. We'll have to watch Intel. While it's only August, I too have reservations about keeping my hopes up for a sub-$2k unit by end of the year.

Has anyone compared side by side the latest 4th gen. samsung dlp vs. the D-ILA now on the market? Prices are similar.

Hopefully the 52" JVC HD-ILA we just got in the store this week will be parked beside the new 46" Samsung HD3 DLP projector (63 series) so I can get a good look and compare these two amazing technologies. I can't wait to see the 85 series pedestal-style Samsung!

Although DLP has great potential for growth and improvement, it will be some time before 3 chip DMD units reach a more affordable consumer price point. With JVC's version of LCOS already down to the price of a single DMD unit from Samsung (JVC 52" D-ILA: $4999 CDN, Samsung 56" 63 series DLP: $5300 CDN). In terms of reliablity, a stationary prism combining RGB from 3 chips is much better than a rotating, mechanical colour wheel whose speed must be maintained or else the colours of the TV are totally comprimised. (This wheel speed issue coming from a Samsung rep.) Plus we've already seen JVC reach much higher than full 1080p resolution with there professional HD-ILA projectors. The DMD can't touch resolutions of the HD-ILA yet. We'll have to see if the upcoming xHD3 DMD will actually acheive the 1080p like it supposed to.

NOW we see Phillips' 52" LCoS hitting the local Comp USA. It's priced also in mid 3's, similar the new gen samsung dlp on a pedestal & the new gen mitsu.dlp. Any clear cut winner in these rivals? The JVC DLI looked brighter to my eye than the mitsu, although the salesmen at best buy seemed to like the new mitsu. Anyone see any of these side by side? (They are kind of spread out at my local shops, each salesman seems to have diff. favs.

Go into the Goodguys in The City OF Industry, CA. They have them both displayed side by side with the Samsung and the Mits DLP.

When comparing these two formats, be sure to ask about lamp life. DLP lamps need replacing every 600 to 800 hours, at a cost of $600.00 to $800.00. JVC's ILA format doesn't have this issue. With a brighter picture too, it makes the JVC system the clear winner over DLP.

DLP lamps need replacing every ~3000 hours at a cost of $200-$250.

[Dr. Anthony]

Philips Cineos and JVC rear projections work off of a 3 chip system that is superior to a single chip DLP no matter how fast you spin that color wheel. JVC LCOS projectors are just about the best projectors going right now and thier technology by our eyes has more vivid colors, no "rainbow" and great contrast ratios. We think by year's end that samsung's hold on the rear projection market is going to slip significantly due to the widespread availability of these sets and others like them that are being released.

Let me know if anyone else has the same concern.
I set up a new JVC HD-ILA yesterday and the heat output is tremendous. I was told at the store that the tv would only come out 17" from the wall, but I had to move it out over 2' to prevent the heat from the back burning the paint off the wall.

Secondly, when it is on, the tv sounds like a supercomputer with a huge din. I assume this is a fan(s) working to cool the bulb.

I did not expect this because in the store you can't notice it with all the background noise.

This is my first new tv in many years and I'd like to know:

1. Is the sound din normal, and similar on all LCD-type tv's?
2. Can I move the tv back against the wall and put a piece of tin foil on the wall to reflect the heat back towards the tv and up?

Thanks for any advice. I may yet decide to return this to the store and switch to plasma.

[Dr. Anthony]

This is kinda concerning. With a rear projection set, there shouldn't be THAT much heat and THAT much noise. No televsion should burn the paint off the wall no matter what television it is. I just hope the vents aren't blocked by something or the air intake vents are blocked, making for an extremely hot internal setting and the fan continues on high. If I were you I would check that bulb or vents for adequate flow. Read the manual. If the tv is recessed within an encloseure would be probably a negative and cause problems depending on where the air vents are located.

BTW I don't think tin foil will be able to stop the heat that you are talking about. Temperatures that can melt paint will not be effectively dispersed by foil.

We are considering selling this set. If there are heat problems and they are consistent, we will consider skipping this unit as a viable option for our customers. I think this may be a unique situation.

[Unregistered]

The tv is not enclosed in a cabinet and all vents appear to be clear. Also the noise starts the minute I turn on the set, so the bulb isn't even hot yet.

On page 4 of the manual it says the minimum distance between the back of the tv and the wall should be 50mm (that's about 2 inches) - I have moved it out to 100 mm to be safe.

(To clarify, I said in my original post that I moved it out 2' from the wall, but that is from the front of the TV stand to the wall, not from the wall to the back of the set itself.)

Get this: the manual also says, "The TV will generate a slight amount of heat during operation..."

I put a thermometer on the wall in the path of the exhaust from the bulb and the temperature reached 100 degrees F within one minute.

In the expert's opinion, is that a "slight" amount of heat?

I'll be going back to the store soon to compare my set with the floor model. It just may be the way this TV was designed???
Thanks

[rgriffin25]

I have had experience with a couple of these TVs at work and neither of the ones I have installed put out that kind of heat and did not make any audible noise. Maybe the best solution for your problem is to exchange it for another.

[route42]

just curious as to the 1280x720 display listed on the jvc site. i notice it says it has scaling technology that makes any source 720p minimum, but i see no mention of this set being capable of displaying 1080p, which is what GOOD hd is considered, right? maybe it is implied in the 1280x720 listing? guess i have some more to learn. can anyone help me with this? i bought this tv the other day and am awaiting it's delievery.

thanks....

A few of the new Samsung DLPs and a few other brands are starting to support 1080p. The problem is there is currently zero 1080p video available from any source.

The tvs that can support 1080p do so by deinterlacing 1080i or scaling lower resolution progressive formats; ie 480p, 720p. None of them accept 1080p input because there are no 1080p sources and likely will not be for the forseeable future.

1280X720 is the native resolution of this set. So any format including 1080i will be scaled to this resolution. Don't let the larger number (1080i) make you think 720p is inferior. For FOX, ESPN, and ABC they are broadcasting all of their HD games in 720p. The game last night on ESPN looked spectacular! It is true that eventually DLP and HD-ILA will be capable of 1080p, it doesn't mean it will be broadcast by the major networks.

This JVC set does the best job with analog broadcasts that I have seen thus far. Which in my opinion is a huge plus considering most HD-ready TVs do a poor job with analog sources.

[Rob Babcock]

I'd expect 720P to actually look better than 1080i. Eventually though we should have 1080P. I'm not aware of any DLP panel that can display that resolution, but there could be one. As rgriffin25 said, that shouldn't be a problem with a good scaler.

I also didn't realize there were any *affordable* 3-chip DLP projectors yet. What do they cost? I will admit that since I'm already using a DLP FPTV, I haven't kept up as much with new developements (can't afford to get a new one for the foreseeable future anyway).

BTW, how how does the PJ get, "Unregistered"? If 100 degrees F is the tops, that's not really all that hot for a PJ. Nor should that be a fire hazzard.

[Dr. Anthony]

I also think that there is something wrong with that television for it to sustain high temperatures and continue the fan going constantly. I would try to get a replacement.

I do believe the bulb of a projector can hit upwards of 120 degrees routinely. Ever touch a regular 100 watt bulb in a lamp after say an hour's use....ouch. Now combine that with the 150Watt bulbs of a say a standard projector and put it in a very tiny space....it has to get hot, but with proper venting, fans and heat pipes it can be dissipated quickly.

1080p contains a tremendous amount of bandwidth that broadcasters cannot pump easily into the current system as far as I know. An average 1080i contains 1/2 the bandwidth of a 1080p methinks. I do believe a 720P is about the highest bandwidth possible broadcast in the US currently save for Japan and perhaps parts of Europe. With more and more sets up converting to native resolutions of 720P or 768P the use of 1080p would be overkill and wasted given the current technology as everything would be scaled down and data actually lost. That would require the set to go at 60Hz full bandwidth. 1080i is much more NTSC friendly at 540 "lines" interlaced and I think is why it is used more perhaps?

There is out there the LCOS Toshiba 57HX32 that does 1920x1080P which is a projection set. MSRP $8999

I know that many standalone scalers can do 1080P but unless you have a LCOS projector capable of 1400x1024+ with an anamorphic lens or a Plasma that can do 1024x1024 all that vertical info will be lost. As it stands a 1024x1024 16:9 has roughly the same # of pixels as a 1280x768 so there is truly no improvement. I do believe that there is only one current LCD that can do 1920x1080 in 1080p and that is the 45" sharp aquos and they wont be shipping until October. We are still waiting for the Samsung projectors, LCD's and plasmas to show up.

Does anybody else know of a true 1080p setup other than the ones mentioned or the extremely overpriced ones that most cannot touch?

Thanks :D

thanks for the answers guys. i can't wait for my set to arrive. i guess my lack of knowledge falls between the difference in 720p and 1080i. i mistakenly thought when i saw 1080 listed it meant 1080p. i think you all have shed some light for me though, and i really appreciate it.

Well, I've been to three stores to check the heat on the HDLA floor models. I've concluded my set is operating to spec. In the stores the sets are away from the wall so it is more difficult to detect the heat. I put my hand over the vent on the back of my tv, and the heat coming out of the floor models at all stores is comparable.

A call to the JVC customer service people also leads me to believe my tv is functioning as they intended.

However, in my personal situation the tv's DIN is too loud to tolerate in the small den I have it in, so I'm going to take it back and get something else - probably plasma.

Thanks for all those who chipped in to help me!

[rgriffin25]

I have known a few plasmas to produce considerable heat and noise. Keep this in mind when shopping.

[Unregistered]

Excited to have found this forum...as I have been looking for reviews on this JVC set for sometime. Have seen a huge difference in price on this set..and have concluded that purchasing it online is cheaper even w/ shipping costs. Would anyone know of a what site would be best for such a purchase. the cheapest I found was $3300 est. incl. shipping. Thanks all in advance....

[Unregistered]

hi.... i just ordered the 52" jvc hd-ila from drplasma.com at 2374, shipping was under 300.... i hope it's as great as everyone says, and doesn't melt the paint on my walls! i'll let you know

[Unregistered]

sorry, make that 2474.

Check out the review of the JVC HD-52Z575 at C-NET, not very complimentery, they gave it a 6.3 "FAIR" rating, consumer ratings not much better.

[Unregistered]

Well...beauty is in the eye of the beholder. I was the Samsung DLP and the JVC side by side, and I got to tell ya....the JVC was impressive. It was alot brighter than the Samsung, and overall pic of the JVC looked really really good. Unless something else comes along in the near future, I think this is the set I wll go with.

[MarkOcena]

At my store we recently got the new Toshiba DVD player with HDMI output and 720p upconversion. I did not hesitate to put it out for demo right away. Hooked up with the HDMI to the 52" JVC's digital input, with Star Wars episode 6... very nice. I was impressed with the quality of the presentation. From about 9 or 10 feet back, the JVC gave the scene close to the kind of depth you see with HD content.

They'd probably be a similar effect with the DLP based TVs. Everyone should see this kind of demo for these TVs!

[Unregistered]

well, my JVC should arrive in the next 12 hours.... i'll tell you what i think... any questions or things i should look for?
peace

The fan noise on my JVC is intolerable. I can hear it constantly 15 feet away with volume turn up to 20 during news broadcast. Are all JVC HD-ILA like this or is this only a problem with earlt production models (mine was manufactured in August)?
The picture quality is fantastic but the fan noise is a deal breaker.

[Unregistered]

I just received my 61" D-ILA yesterday and was wondering if the constant hum/buzz of the fan was normal. Reading these reviews confirms it for me that it is. It's incredibly irritating. It's a deal-killer. I'm sending mine back. Don't buy one, trust me.

[JAVZLOGIC]

Dude....I'm getting mine tomorrow. I hope its not as bad as u say....61-inch as well. When trying to decide between the Samsung 61 and the JVC, the JVC had the best pic overall. Will let u all know tomorrow how it goes.....

[Unregistered]

We have had a JVC HD-52Z575 for about 3 weeks and we love it. The picture is great and nice and bright. We have the TV in front of a bank of windows that look out over the city and the picture is still very visible.

I have not noticed the fan noise while the TV is on. When it's powered off, and it's going through the cooldown phase, the noise is audible, however it is much quieter than my PC fan. One time when I powered the TV on immediately after having powered it off I did notice that the fan noise seemed louder than usual. Perhaps the fan has multiple speeds depending on the temperature of the bulb assembly? In our setup, the TV is about 2 feet from the wall/window so it has lots of ventilation.

As far as the CNET review goes, I think they must have had a bad set. The picture on mine is great with none of the problems described in the CNET review.

I would like to point out a couple negative things that you are unlikely to hear about in the showroom though. One is that you cannot turn the TV on for about 90 seconds after you turn it off. As well you cannot turn the TV off for about 60 seconds after you turn it on. This precautions are to protect the bulb. I don't know if all micro projection TVs have this limitation but it struck as unusual since our last TV was a CRT.

The second thing is that the twin and index modes for viewing multiple screens on the TV at once are not very useful given the limitations that they come with. In particular, the index mode can only be used if the cable input is used. And even then it has functionality issues.

Overall though I love this TV and am very happy with our purchase.

I just bought the JVC hd56fn97 and had visions of hooking up my computer to it and with wireless keyboard, sit back in recliner and surf the web. When ever I connected the PC, it first showed a splash screen saying windows 2000 is starting up. Then it'd go no farther and "invalid signal" flashes on the screen. The only way I could get it to work was by stating windows in vga mode, which is only 16 colors and is totally useless. Please tell me there's a solution. I'm new at this and hope this is the proper place for this post! Thanks Skilz
