Pioneer PDP-5080, 6080, 5010, and 6010 Calibration Issues Part II Print E-mail
Written by Kevin Miller   
Thursday, 05 June 2008

pdp5080hd.jpgOn April 19th I published a short piece on a rather serious issue I encountered in the field while calibrating the very popular Pioneer PDP-5080 720p resolution plasma panel. You may recall that when I completed the grayscale calibration in the service menu, and exited the service menu to take measurements to check the accuracy of the grayscale, I found that it hadn't retained the calibration settings at all. Quite by chance, I found that if you turn off the Pure Cinema, then the calibrated grayscale returned.

Of course, the big problem with that is Pure Cinema is the video processing engine of the Pioneer. The Standard mode provides 2:3 pull-down for film based sources, and the Advanced Mode, provides 72Hz vertical refresh, which is compatible with Blu-ray's 24fps designed to eliminate the Jutter that is created by 2:3 pull-down. Needless to say, this is a huge downside.

After several more regular line PDP Pioneer calibrations, I did run into the issue two more times, and was able to figure out how to fix the problem. I discovered that a separate grayscale calibration has to be done for HDMI for 480i standard definition. Once this is done, then the calibrated grayscale for the 1080i/p is miraculously fixed, and it holds irregardless of the Pure Cinema setting that you choose. My measurements indicated that 720p was not affected, and the grayscale was accurate. Thus, it was not necessary to do a separate grayscale calibration for 720p as with 480i. Note: It turns out that the analog video inputs (component video inputs) are not affected by this problem.

Unfortunately, I have heard a rumor that Pioneer has stripped the calibration parameters that professional technicians need in the Service Menus of the upcoming Pioneer PDP-5020, and PDP-6020. If this is true, I will be recommending other Plasma models to all of my clients in the market for a new 1080p flat panel HDTV. I will be reporting back on the upcoming 20 series panels, and I will give you a full report.

BigTom4Prez - 5080hd calibration   | 204.153.88.3 | 2008-06-18 14:54:47
Kevin,

I just wanted to ask you to clarify your statement.

"I discovered that a separate grayscale calibration has to be done for HDMI for 480i standard definition. Once this is done, then the calibrated grayscale for the 1080i/p is miraculously fixed, and it holds irregardless of the Pure Cinema setting that you choose."

Does this mean that RGB grayscale calibration using 480i standard would be the only way to ensure proper grayscale for the 5080hd?

I own a 5080hd and have been trying to calibrate for 1080p24 source. I noticed that the only reliable grayscale calibration is with user mode. (Movie mode is crazy. It seems to lower Blue levels across the board.) To complicate the situation, there are two RGB tables used by the 5080hd. All normal sources like 480i, 1080i and 1080p use table 1. Using 1080p24 source will activate the 2nd RGB table. Finally, the Cinema Modes definitely changes grayscale. Standard seems fine but Advance is a headache.

I calibrated using 480i standard in the past and gotten good results. I am recently using 1080i and 1080p24 refernce disks but the results are mixed. If you see consistent results with 480i grayscale calibration, it would explain why I am having issues.

I figured out my issue with the 5080HD.
Advance mode causes a 10% drop in Blues for RGB across the board. Both of these issues are suppose to be fixed with this year's models.

Here is the only major issue. Since Advance mode causes a 10% drop to Blue, you have to decide which mode to calibrate. If you dont use Advance mode, it is very easy. Just calibrate grayscale with PureCinema off and all the modes (except Advance) will have perfect grayscale. If you use Advance (like me), then calibrate using advance mode with the understanding that all your other modes will be 10% higher for Blue.

Finally, the Table2/50vs settings are only used with 1080p24 and PureCinema is off. But you see the 50vs settings when you have any 1080p24 source. But with PureCinema enabled, the settings in Table1/60vs is used.

Hi,

PureCinema mode has nothing to do with or should have nothing to do with grayscale.

What I discovered is a glitch. I am finding now that if you simply do a grayscale calibration for HDMI set to 480i, which usually has to be done with a generator as most Blu-ray players don't put out 480i over HDMI, then the grayscale is accurate for all resolutions, and you can use the PureCinema for its video processing; standard for 2:3 pull-down, and Advanced for 72Hz for 24fps material although it is flawed.

By the way the new regular line Pioneers can not be calibrated as they have stripped all the service menu items for that out of the new sets. Only Elites will have the ability to have the grayscale calibrated. As a result I will no longer recommend them.

Thanks Kevin.

After your statement about PureCinema, I checked my settings again. It turns out that the blue drop was caused by Movie mode.

The only tricky part about the 5080HD is to calibrate using 480i or 1080i source. There is a bug when using 1080p24 source. When you access the SM, it brings you to table 2. But 60 and 72hz operation use, table 1. Table 2 is used only if Pure Cinema is off and 72hz activated. This is probably the problem you found during gray scale calibration.

Thanks for your reply and your articles.

So Kevin if I was to use RGB offsets in the SM on my 4280 I found on forums would I want to implement these(enter the SM) while viewing a 480i SD source over HDMI then? Would I turn off Pure Cinema while I do this as well?

Thanks
kevinmiller   | Super Administrator | 2008-07-17 05:30:45
Hi Jack,

Yes input an HDMI signal at 480i and do the grayscale in the Service menu. Then Pure Cinema will work just fine and the Middle Color Temp will be calibrated for all inputs. I think you have to do a separate calibration for Component if I remember correctly. Are you a calibrator?
JackD   | 208.78.19.1 | 2008-07-17 09:13:49
No not a calibrator, just someone who's gotten addicted to this stuff. I've done a SM adjustment with offsets that were suggested on a forum while on a 1080i signal and they look great. But by the sounds of it it would be better to reset them and re-implement via a 480i signal(just go to standard def on the cable box I guess)

Do I need to turn off Pure Cinema during this? I always leave it in Standard.

Anyways thanks for the quick reply and gotta say I love your site.

i recently had to replace a board in my pioneer pro 150fd after 18 months, i was very surprised i guess. the problem is i lost the calibration from the geeks. is there anyone that has those numbers, i thought i saw them a while back on the list when i referred this site to a friend??

I guess that you should give the recommendations about dissertation statistics referring to this topic making. Just because students don

The same issues with others I encounter. Much better if we try to check the unit first or do read the manuals before doing certain things on it. Online dissertation help and dissertation proposal can help you on this, where you can write up everything.

I opine, you should utilize the article submission service for your note referring to this good topic, because that is obviously hot and must not be hidden from public!

BigTom4Prez, this really explains most of the issues, thanks for the contribution. I turned off PureCinema and calibrated the grayscale. It works well now.

This is the best watch I have ever owned. casio standards watches It is very reliable, itself will be set to midnight every night to 4:00. I do not put it off until now.

Swim in the pool, take a bath when I wear it. I have been diving to 300 feet without any problems. Cruise watch reading.The night, such a ship, the backlight is great, because it can not receive the signal, reset the time in the room, surrounded by metal, it has a great time zone easily anywhere on Earth you can change. -O-Flex band, because I do not want to, I Spidell distorted, the band can. I love the fact that you can put it in any standard belt.This is my second watch of this type. casio sheen watches What to wear every day, out of the first lasted eight years. I never put it off, from dawn until dusk. If you do not want to keep time, and finally got it. New battery in the first installation is complete, it does not come back to life. If the clock has been shelved, because, after all, a long time, it has specific, I figured out, I have another one just like it. That's why I look at my second. The appropriate time zone settings, accept my new, its development, it has been a great success. There is no doubt that I will buy another one, when you play a good-looking, you do not have to set time and date on.Absolutley, super cheap, and I recommend it to anyone looking for a long-term digital clock.The clock is in perfect condition.


Can be shipped as soon as possible, because it is reasonable to transport. casio watches See it now, because it is my job, I see it, the reason for more than a decade ago, I bought the first thing I bought, began to look at the wound, wear. Great watch. This is the second Waveceptor I have. Until the battery died, sustained two without any problems, and installation cost of a new battery is normal wear and tear, the new personal reading like reading the exact time. If you have, then I buy the cheaper it will be modified, which is self-help, and the actual light of day at the end of each month. Alarm stopwatch or ideal, but the new features, like the problem of course has a Toyota and Honda long life expectancy will also.CASIO reliabilty.I do not mind all the metal separator, casio watch men I was somewhat pleased with this watch. You can very easily with an extension that is good. The end of daylight saving time has come for this guy, but I do not want to change the NIST time exactly match. Need to trust my old hockey has changed, so I will finish it. There is a simple time to my other Casio WV-M120 signal change is not observed. Two clock settings for daylight savings time. Disappointed. Casio, you can do more.
