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

 

[Unregistered]

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.

"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.

dlp vs. D-ILA

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

Side by Side

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.

dlp vs. D-ILA/LCoS

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.

Jvc Hd Ila Vs 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.

LCOS will surpass DLP

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.

HD-ILA Heat Issue

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]

Hmmm

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.

Heat

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.

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.

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.
