Without being in their labs, anything you or I say is simply conjecture. There's no guarantee it won't be fixed in current models, just as there's no guarantee it will be fixed in the next models.

This kind of issue (vacillating brightness), is not unknown in other TVs from past years. I recall having a Sony XBR CRT that displayed a kind of brightness oscillation when the 'intelligent contrast' (or whatever they called it that year) was engaged. It wasn't exactly what we've seen here, but it wasn't totally different either.

Right now it would appear the are having trouble putting their finger on it. It has been nearly 4 months since the Reps got caught with their pants down and blurted out "FW update" that Saturday night at the shootout. I didn't fall for it that night, call it a gut feeling. but you could tell they were making that up as they were not techs but sales reps.

You can bet they are making an all out effort to find a correction before production of the 2012 ELITE.

You're talking about two different issues here. At the shootout, a fix for the cyan issue was discussed, not the pulsing. Unlike you however, I do believe they've been working toward a cyan fix for the current model. I'm still optimistic they'll come up with it, but if not, as owners agree, it won't be the end of the world. This simply doesn't detract from your viewing enjoyment.

I honestly think the greatest impact of a cyan fix would be to silence critics, not increase the viewing enjoyment for owners to any significant degree.

Keep in mind this is not a discontinued product line. The current Elite is still very much in production. The next Elite is not due out until September at the earliest. If it actually winds up using a different panel, it wouldn't surprise me if that date slips as so often happens with many new models.

So the current Elite will be the only Elite for the bulk of this year. That much you can pretty much bank on.

As to the fix for the current model, we shall see.

I'm with boulder_bum on this one. I've personally checked 5 of these sets and saw no difference in pulsing between them when watching the same material using the exact same settings. Sharp will never admit to seeing the problem - that's normal for all manufacturers. They never willingly admit there is a problem until they have a fix, it's a liability issue. Do you honestly think they would have admitted the cyan issue if not for the shootout situation?

rmongiovi,

I totally understand you wanting to enjoy the set and not worry about issues. But if curiosity gets the better of you, please test the clip from "The American" I posted in this thread in Elite Pure mode. If that does not flicker for you, then Elite has definitely fixed something. The beginning of this season's premiere of Boardwalk Empire also has a very good test case - the sky/clouds goes crazy in Elite Pure mode. I can upload that if anyone wants to see it, but it's only visible on Elite Pure.

I can confirm from my calibrations that 2pt settings are independent of the 10pt settings; they do not affect each other whatsoever. Basically, this kind of invalidates all credibility of the cnet calibration settings....for me at least.......(how can a pro calibrator miss this????) :s
post #6036 of 13419
My concern, besides the DSE issue, (for which I'm on my third set now and counting), is color.

The set's end user CMS controls are not well implemented it appears, and behave in non-linear ways with unexpected HSL adjustment results. Sharp has said as much to me, in that the end user CMS controls are not meant for a thorough/complete calibration of the panel, but I'm still not clear why Sharp would provide those level of controls but then not properly enable or code them. I found that every color mode (THX, Movie, etc) with local dimming off, read very low pre-cal saturation levels.

I did enable the ISF mode and tried calibration using those CMS controls (using Chromapure and a DIII), and discovered the color tracking at different stims was horrendous for primaries and secondaries (at times 25/50 or 50/75 stims for colors almost overlapping, far from their target and color shifted as well. The calibration report (either using 75 or 100% cal patterns) looks excellent, but because of how poor the set is tracking color, the results are less than optimal.

Now, I don't pretend to be a pro, but I've spent a lot of time patiently learning this process, and have had superb numerical and visual results using the same calibration set up with my VPL VW95 projector.

I'm having some followup conversations with Tom Huffman of Chromapure, who had come by my home a month or so ago, and who was not satisfied with the results of his work that evening (albeit the first time he had worked with that panel). If I read his recent post correctly in the Chromapure forum correctly, he has a another client who experienced similar color issues with this panel.

http://www.avsforum.com/avs-vb/showt...9#post21502249

Not sure what is occurring here, and am interested if anyone else here has had the opportunity to do a detailed Chromapure or Calman type of calibration on this panel, either with the end user CMS or ISF CMS mode.

Ah, now you had to go and do it. Yes, it flickers in Elite Pure. There's even just a hint of instability in THX.

So, much better than my first set, but still an issue.

I think we're missing C-Net's point here (emphasis on "I think" ...). I believe they did two different calibrations, one two-point and one 10-point, and posted their settings for both, you pick which one works better for you. If a TV set has both entered, it will use whichever one is selected at the moment. But if you enter the 2-point, then activate the 10-point option and don't enter anything, it's basically just switching off the 2-point values and using no WB compensation. As you say, how could someone who knows this business think otherwise?

I am also a DIY calibrator and no expert by any means but I do see the same color tracking issues with the CMS and greyscale. Although the set can measure correctly using the 75% stim, other stims will look way off. I've reset all my calibrated settings for both ISF modes, the only settings I've set are contrast, brightness, backlight, and gamma. The colors and greyscale still look the most natural out of the box, albeit a bit towards a cooler temp.

Well, this is what David Katzmaier had to say about it:

"Sharp's menu design is confusing. You have to adjust BOTH 2 and 10-point settings. To adjust the 2-point setting you have to turn the "10 point settings" setting Off; afterward, turn it On to adjust the ten points (using the Position slider as you seem to have discovered). The actual "On/Off" position of the "10 point settings" switch has no impact on the picture itself."

So it seems clear he thinks they both apply.

Does anyone know if they checked colors other than cyan at multiple stimulus levels at the shootout?

what I meant by saying that the current Elite's are 'discontinued' is that the product has almost reached EOL (End of Life)...when that happens a manufacturer chooses to focus on the new models and dedicates most of their resources and man power to the new production models...this happens months in advance of the product actually making it to market...there might be a small team still working on legacy models but not enough where a color decoding issue would be still in the works...if some major issue that effects non-videophiles was detected then yes a fix would be rolled out but I highly doubt that a cyan color fix firmware will be treated with the same priority

a cyan fix will most likely only be rolled out with the new 2012 models...all this BS about a fix is coming soon, within 1 month, we'll talk about it with Robert at CES etc is all BS...how on Earth could they possibly chat about it with a person at CES and still realistically be expected to come out with a fix anytime soon?...that would mean that they havn't even started work on this...and no offense but Robert Zohn is a small dealer and not some major player who has enough pull to get Sharp or anyone else to do major product fixes

Ken, you are optimistic about the cyan fix but when it came to the recent FiOS 1.9 update you were way more pessimistic...when in theory the FiOS fix was way more likely then any cyan one

Pinktri, try this. Go back into the Advanced sub-menu and then in Color Temp, turn 10 Point Setting to off. The drop down box is no longer grayed out. In the box, set Color Temp from Low to either Middle Low or Middle, your preference. Turn 10 Point Settings back On.

This will make the picture less yellow, and may be more satisfying to you.

I would not dismiss David's settings based on that. It's pretty well known in the industry the guy knows his stuff. It's also hard to deny how good his settings actually look.

I do agree what he said didn't sound logical regarding the 2 vs 10point settings, but I wouldn't rule out the possibility that it might just have been poor phrasing on his part that's resulted in this confusion.

Hate to to burst your " I think everyrhing is bs" bubble but Robert is EXTREMELY well regarded despite his size. He was the only dealer invited to the Sharp press event in NYC when they formally announced these sets. He also opened the press event with his remarks. He also saw pre preductions models at Sharp in NJ before anyone else..

Get your facts straight mate before you start making incorrect statements

I was pessimistic about the timing of 1.9 in the N.Y. area, not whether or not it would ever materialize. There's a big difference. Now, why was I pessimistic about the timing of 1.9? Because we were told no less than THREE times, over a span of nearly ONE YEAR, that 1.9 was 'imminent' or as Verizon liked to say 'a new FIOS is coming soon'.

So IMO that's a big difference between the cyan fix and 1.9. Might a cyan fix never happen? Yes, I'm sure it's possible, but I will remain optimistic. I think it's also important to note that sometimes manufacturers DO offer firmware updates after a product is no longer current. Does it happen often? No, but it surely does happen and I've had numerous firmware updates for equipment I've owned that was no longer in production.

To put this issue in perspective (again), here's a recent post by Kevin Miller on another forum that some may not have seen regarding the cyan issue:

"HI All,

I like Ken find this really amusing. The reality is the Cyan issue will rarely be seen since it only occurs at 20 to 50% luminance levels where it goes blue. above that it tracks well and is correct. Yes I would like to see them fix it, but considering the rest of the set's amazing attributes like the best contrast of any display to date, and superb video processing, gamma, and grayscale tracking I still rank it as one of the best sets out there as do all of the technical publications worth their salt in our industry. The only reason I caught the flaw by the way was because we had a wall of other TVs surrounding it and one of them was known to be verry color accurate."

Very true. I think it's very premature to condemn anyone and everyone because the fix has not yet been released. I think some greatly underestimate the influence that a 'small' guy like Robert has. He has many connections and knows many industry insiders. Does that mean he can snap his fingers and 'demand' a fix from manufacturers? No, but he has more influence than some think. He greatly facilitated an exchange for me because of his high level contacts within Sharp.

Steve big thanks, I will try it when I get home later tonight. I appreciate it. what I have tried; performing the CNET settings and seeing it's a little to yellow would go back and change the color temp but things looked too blue. I never thought of changing the color temp with the 10pt settings off then going back and turning it on. This could be what I was missing.

Ken: Thanks for all your responses to the critics. Without your efforts, a casual reader would get a much poorer impression of this fine set. Regarding those critics, if the cyan issue is fixed, they will first question if it really has been fixed and once that's proven move on to the pushing the pulsing issue.

Regarding color tracking, check out post 5486, page 183 where D-Nice posted his results. Other than cyan those results look good to me. Perhaps Tom should talk to D-Nice.
post #6051 of 13419
OK

So here's a thought


For those of us who use the CNET settings what are we going to use when the cyan fix arrives?
I doubt anyone is going to re review the Elite and post new settings...

I understand a pro calibration is the final answer but it takes time to arrange...

The problem with D-Nice's charts is that they show only the CIE component of color, not the luminance. To track correctly the color decoder has to get that part right too.

I agree with Pannus, this isn't string theory (or even rocket science). It's well defined and just a little bit of matrix math. We can even do it in an Excel spreadsheet. But Panasonic can't seem to get it right. Sharp apparently can't get it right. My gallows sense of humor finds it quite fitting that Samsung, which is always being criticized for stealing technology from other companies, seems to be the only design that gets it right. Too bad Sharp and Panasonic don't steal from them.

I just tried this. Turning 10pt off and changing color temp absolutely changes the image. However turning 10pt back on does absolutely nothing to change the image.

I got a little lost on the discussion regarding the 2pt/10pt and whats on and off but on my TV, with CNET settings for color, it isnt changing the image turning 10pt on and off.
post #6055 of 13419
hmmm....I guess there goes that. I'll give it a try this evening and report back. In the mean time, I've really become used to the cnet settings and love the brightness and image quality but definitely notice a little yellow push. If anyone has any other suggestions on how to resolve this I would appreciate it. I've tried to calibrate with my WOW disc but changing the hue, value and sat doesn't seem to help much. I believe it's the 10pt settings causing the push

I just tried the same thing and got the same results you did (with CNet settings). 10pt on/off does nothing and color temp does.

Dont despair yet. You may like the picture better by simply changing the color temp to mid-low or mid.

Its funny, I do get the "yellow" push on some of the programming I watch on Direct TV but not when I watch Blurays.

If you've got both 2 point and 10 point calibrated to the same standard, so that they're not visibly different, how would you expect to see a difference when you switch between the two?

Even when I compared calibrated 2 point to uncalibrated 10 point, the difference was only about 2 delta-E, and that wouldn't be visible to the eye. It's obvious on a meter though.

Yes this is the exact thing I'm experiencing. It's strange, maybe programming has something to do with it. Like I said before the golden globes looked terrific and skin tones looked spot on. But I flip to another program and crazy yellow push. Blurays look great and the still shots from the WOW calibration disk looks good. One thing I have notice though is the yellow on my my comcast guide along with blues look kinda greenish compared to my panny plasmas. Also african american skin tones seem to take a little green/yellow hue to it. I've set my tint to -1 and it has helped a little.

Thanks Dave. That's really almost my entire motivation for my posts here. There is so much embellishment, so much misinformation, that anyone coming here for the first time would be shocked that the Elite can even produce a visible picture.
