LCOS or DLP?

Looking at the brand new JVC HD-ILA lcos 52" and the Samsung HLP5063 dlp gen 3. Both are awesome, but the lcos seems more advanced. Is it too early to buy one tho, given that this lcos technology has just been introduced? If dlp is the way to go, is it worth waiting a few months for TI's generation 2+ chip which has a better contrast ratio than the gen 3?

The LCoS will do blacks better and usually are 1080p, which IMO justifies a higher price. However there have been reports of LCoS being too dim. No matter what anybody tells you digital displays are so new that ANY one you buy right now will have a high risk factor.
It comes down to personal needs/limits;

1)Old cheaper proven displays: direct-view CRTs or RPTV/FPTV CRTs.

2)New expensive unproven displays: plasma,LCD,DLP,LCoS,SXRD,etc.

Of the digital displays LCD seems to be the most stable and the computer display industry will support these well into the future.

TI is still upgrading and improving their chip so DLP is a hit/miss choice for now.

1)Simple answer, wait for the gen 3

2)Complicated answer, waiting in this game is something you'll never be rid of, soon as you buy the gen 3 they will have specs announced on the gen 4.

I wasn able to watch the JVC HD-ILA lcos 52" along side a Mitz DLP (not sure what generation of chip) and although I was sold on the DLP going in, the JVC had a significantly better picture. The content was a Hi-Def Soccer game, and after we toned down the colors on the JVC, it pretty much blew away the DLP. I was also able to detect the rainbow effect in the DLP, which I had never seen before.

HH Gregg should have the 61" in this week, which is where my interest lies. The other unit that I am interested in is the RCS Scenium 61" slimline. At 8" deep, it is a wall mountable DLP due out in September. MSRP...$9000...wow. At that price, I will give up the wall mounting and go with the LCOS.

Thoughts?
Thanks!

Does LCOS have the same problem has other rear projection's in that the brightness dims when you move to the side or above the screen?

LCOS blacks are no where near as good as dlp. The best lcos can do is a dark gray. I just purchased a 62" mitsubishi dlp with the HD2+ chip. HD2+ blacks are second only to crt.

Actually...SXRD(sonys version of LCoS)is second only to CRT blacks, then LCoS and finally DLP.

The LCOS technology and the JVC's NEW D-ILA technology although similar are not the same. The JVC claim is their D-ILA (Digital Direct Drive Image Light Amplifier) Gives true HDTV performance by packing 2048X 1536 pixels, a total of 3.2 million pixels, on a single 1.3" chip. This enables display of HD images at full spec resolution of 1920 X 1080, with room to spare. The next generation of DLP by Samsung will offer 1920 X 1080 early next year at about $9,000. MSLP.
JVC's current model HD52Z575 can be purchased at about $3400. or less. I compared it to the Samsung 5063W DLP and thought the picture blew away the DLP. My complaint was the color to rich and contrasty , but understand that can be toned down with adjustment. The JVC showed extremely black blacks and more shadow detail then the DLP. However. that was looking at a DLP 3 chip. The 2 plus
will be better. However, the DLP's won't be able to display
1920X1080 at a reasonable price for some time. I sure would like to know more about the JVC D-ILA compared to the Samsung DLP's before I spend a graet deal of cash for the new Digital diplays.
I'd sure appreciate some feedback!

The RPTVs for this year are 1280x720 - right?

I did the same same Samsung vs. JVC [HD-52Z575] comparison as described in lanarich's post. I came to the same conclusion, the JVC was the hands-down winner. I believe I'm right in saying that the JVC implementation of LCoS uses three chips. A Philips LCoS on display in the same store using a one-chip system was less impressive, and would not have been a good choice vs. Samsung DLP. On the HD-52Z575, I noticed a diminished picture when looking from above but no, repeat, no loss in picture quality when looking from the side. One thing worth noting is that while the HD-52Z575 will accept 1080i signals, it displays them at 720p.

i just ordered this from tweeter. i started out after the new generation of the samsung models. apparently tweeter is just trying to unload the older models and the showed me the 52" which looked great and was "reasonable". the next week the had their private sale which made the 62" a steal. any problems or complaints?

I looked at the JVC HD-52Z575 (3 chip D-ILA system) yesterday. The picture was sweet. I compared it to a Samsung DLP 50". I much prefer the JVC. Are there any reliability issues with the LOCOS systems?

I went to the local Best Buy store and was able to view the same DVD on a Samsung 5685W, Mitsubishi 50" DLP, Toshiba 5284, and the JVC HD-ILA 52". The Mitsubishi was the sharpest set but too dark, the Toshiba was a very soft picture but less expensive, the Samsung was the brightest of the DLP's but not as sharp as the Mitsubishi, the JVC was by far the brightest of the bunch with acceptable (to me) sharpness and IMHO the best buy of the group. It's blacks will always be better than a DLP due to the type of technology employeed.

Ok, just to clear a few things up for me...

The JVC HD-ILA 52" uses the LCoS system, correct? Do you think that it is worth the cheaper buy instead of the upcoming Sammy DLP-4674 or the current HLP-5085? The JVC is a larger TV, but uses the LCoS system whereas the Sammy DLP's use the new DLP2+ technology.

I too am in the same boat in comparring/deciding between Samy's 5674W (hD+2) and the JVC's HD-ILA lcos 52.

Would GREATLY appreciate learning about any additIonal discussions, reviews etc. between these manufacturers/models/technologies.

After much research, we chose the Samsung HLP5063W. It took the better part of six months to screw up the courage and pull the trigger on such a major outlay. We did, last June, and got it from Best Buy for $600 off MSLP [they met an online competitor's price], along with Monster cables, [no theater audio yet], stand, line conditioner, and a four year service extension. It took a few days to arrive and was not too difficult to set up. Incidently, we routed the cable box via the surge protector to the set and hooked the DVD via the DVI, but, the picture was poor. Comcast said to use S-video for the DVD and the DVI for the HD cable box, but to skip the co-ax surge protection because it weakened the signal, as did the splitters in our walls. With that wiring and a new direct co-ax from the source, the picture was robust and wonderful.

But, from day one, we noticed a soft gray smudge in the center of the display, about six inches from the top. I should have sent the thing back then under the 30 days-no hassle promise at Best Buy, but everything else seemed fine and time slipped by. My advice in retrospect: tolerate nothing in the honeymoon period. Get a replacement if there's the slightest flaw.

About five weeks after we got it, the set began to intermittently balk at coming on. All three LEDs lit, indicating the bulb needed service, according to the manual. Yet, it was possible, for awhile, to force it to work again by unplugging it, waiting a few minutes to a half hour, then plugging it in again. After a couple of weeks of that nonesense, it quit altogether, and we finally called Samsung for help. They engaged a local service firm that had not seen this model before. The serviceman said the lamp was fine. It was decided that the display and one other board needed replacement. When the technician arrived for his second visit, he noted that one of the boards Samsung sent was not what he was told was needed; however, both were installed. In the process, speck was noted on the face of the DLP chip removed with the old display board. The tech brushed it off with his finger and acknowledged that it was in exactly the same position as and most likely source of the onscreen smudge. That was the good news. The smudge was gone. But now, the blue and red were reversed. Green, black, and white are relatively normally. All flesh tones are Martian blue. What's happening? The last state of the HLP is worse than the first, but neither Samsung nor Best Buy is ready to swap it out for one the works. Now, they want to try a new "engine."

What's happening? Is our experience unique? I'd appreciate any comment on any part of this long, sad story [believe me, it could be longer] from the hook up to the "repairs" to the experiences of other with Samsung and Best Buy in such cases.

sounds like the color wheel is not aligned. I am not an expert, but it seems possible that it got out of whack when the cabinet was apart. Is it possible that it was installed BACKWARDS? that would (maybe) explain why only 2 colors are f!@#d up.

I think these wheels go 123123 for 6 segment and 1234123 for a 7 segment, 4 being a grayish black. so reversing the wheel would give you 321321, two stays the same, or 3214321 with 4 and two staying the same.

Looking back at your post, I am pretty sure this is what happened.
RGBRGB becoming BGRBGR sounds about right, Doesn't it?

hope this helps, I feel your pain as I had trouble with my Philips LCos, but that is a LONG story.

good luck

Just got the new HL-P4663W DLP with 3rd gen processor...bright, sharp and beautiful...powered by the new Comcast Motorola 6208 HD PVR. About the only thing bad I can say is that it is taking a while to get used to the voyeur feeling of watching tennis, baseball or football...with my old tube TV, I felt remote...with this set-up I feel almost too close...like I'm intruding.

For the price, I've got a great TV...no burn-in issues, not excess heat issues (some plasmas can literally heat your room).

HAppy thus far!

Well...all service agreements are just that...service agreements...they are not replacement agreements...if it is possible to fix an issue, such as replacing an light engine, and that is cheaper than replacing the tv, that is what will generally be done. It could of also been the service techs. partial fault by not checking something obvious first...such as something had falling onto the processor (a lack of understanding how the technology works can be an issue)...sounds like that was what really started the snowball if you know what I mean...

If any of the repairs (single work order) take more than 60 days, head down to your local best buy and pick up a brand new television set, it is in their policy to provide a replacement. Store staff will generally avoid doing this but once you tell them it is policy, they will be forced to do so.

sony will never have dlp. I heard this from a sony rep himself, instead sony has their own version of lcos much like jvc dila. Im not to high on lcos but the jvc does look nice, just wait till the 1080p dlp chips come out next year.

I am in a similar situation. I have a Samsung HLP5063 which I bought from BB two months ago. I called for service regarding a noisy color wheel. The tech came over to my house, took the color wheel out and tried to put a new one in its place but it was the wrong part, so he had to put everything back. The next week another tech came and replaced the color wheel. All the brights were okay but all the dark shades turned purple or had a purple tint. I love watching "Lost" and on dark scenes, I could barely recognize any faces because of the purple tint. I called the shop again and they took the tv with them. After a week, they called me and said that the tv was fixed, so I stopped by their shop to make sure that it was really fixed. I asked the tech what he did and he all he did was go into service mode and adjusted the colors which didn't fix the problem. That was yesterday.

I'm curious if your problem got resolved and what the fix was.

Well, let's hope it's not over yet. I owe you all an update:

About a month after the original post, they (BB's local service sub) put in a whole new engine (wheel, lamp, DLP, etc.). It turns out there was a bit of dirt under the glass cover of the DLP [among other things wrong]) and the set was wonderful again until late this summer. It would come on a little slower, at times it opened with duplicate pictures side-by-side that could only be cured by toggling between channels, then — once in a while — there would be sound but no picture. Again, turning it on an off would help but there was an intermittent screaming noise too; that would usually (not always) respond to a whack on the back of the set. But, a couple of weeks ago, all of the above happened in one night and there were horizontal bands of weird color across the screen. It took two visits and some hassle with the new local service organization but a really pleasant tech brought another new engine and (except for one recurrence of the double image — why does that happen?) all is well. This is one time I am glad to have bought the service agreement! Just in time to se the Eagles take the Redskins and Giants. Now, if only they can dispose of the Cowboys ...

The same greyish spot at the top center of the screen is there. First I though it was the light shining on it, then i thought it was osmething inside the tv it self. Then our TV started to turn purplish-greyish. You have to turn the TV off for at least 30 seconds and then turn it back on in order for the pink crap to go away.

We sent the TV out for repair and the guy is saying there is nothing wrong with the TV. I am so mad because I know that every morning when I turn on the TV for the kids it is purple-pink and that grey spot is just bugging me.

I don't know what to do.. I'm so frustrated.:banghead: :helpme
