Panasonic 11G/12G/13G black levels have seemingly doubled overnight? - Page 353

Says who? My last news from german forums is, that this rise still happens on Samsung-Plasmas of last year.

Stay on topic and don't get personal guys...

Hi Turrican4D

Is it true that you have got your LG PK350 down to 0.01 cd/m2?

Yes, it's true. It's cd/m2 and the 0,012 cd/m2 wre measures in the ANSI-pattern of the AVS709-Disc.

On off were 0,007 cd/m2 with IR and not to measure anymore with my Spyder3 60 seconds after displaying a picture.

In the black bars of cinemascope movies the black is getting even darker and reaches the bottom after approximately 10 minutes the movie has started.

BUT I have sometimes a little amount of pixelmissfires. I have to go up to 0,020 cd/m2 to get completely rid of it.

The tuning is for the most part achieved with only two of the seven potis inside the PK350.

Oh. I've seen tons of posts that refer to some firmware update that fixed that. I was curious if it was ever addressed or not. If not, that's a legitimate gripe with the samsungs.

Wow that is amazing. I wish we could find the same pots on the Panny's and Samsungs. Well, we've tried to find it already on the Panny's to no avail

Maybe when I get a D7000 I'll have a play around

In the meantime enjoy your 8G Kuro blacks on your LG

To Documaker and the rest who are still on this black issue and continue to insult the integrity of good honest people

Three words

GET A LIFE

Sorry for this quick derail, but those TVs in that video clip...are the bottom and side ones 55" and the top one a 65"?

Open question for anybody

Check my post regarding panny's patent regarding correlation between MLL and temperature.

Ah, thanks!

what year did the first reported Panasonic black rise happen?...was it the 2008 models?

I have a 2008 50PZ800u and can tell you that my blacks have risen just as described by others in this thread.

Can someone who is a member of Cnet, please ask David K to give us an update on the measurements of 2010 models? We haven't had an update since September (6 months ago)

is he still even testing them?...I thought his last update was the final programmed mll rise?

http://news.cnet.com/8301-17938_105-20018722-1.html

Not even close.


The last update had the VT25 at .007 mll, it should end up at .01-.012 mll.

They had the G20 at .012, it should end up a .022.-024 mll


We really need an update on these. Someone please twitter David or something. I don't know how.

No.

I think that the "black level rising problem" is not funny

Why panasonic use LG Plasmas on an Panasonic Shootout?



Thas really easy for me, if panasonic do nothing than this was my first and last plasma tv from this company.


Here in germany panasonic does nothing! They give us not even a current firmeware on their homepage.


Can someone tell me something about the lawsuit versus Panasonic?

^That's just a screensaver (LG Blu-ray player?).

I'm shopping for a new digital camera.

Part of me wants to avoid the Panasonic Lumix LX5 at all costs.

Liars.

Sorry to derail but thanks for linking to those video interviews. I am poring through them now. Noticed something in video part 12.

Notice the flickering plasma top right? Why is that one flickering and the others not?

Anyone remotely interested in the black levels should redirect your attention momentarily to the 2011 panasonic plasma [no price talk] thread. Momentarily.

Well, they're not allowing that discussion anymore in that thread. I really enjoyed the "I have a fix but I'm not going to share it with you" stunt

So basically what we know is that a fix to this problem is definitely available, and that all the officially trained Panny techs and D-Nice know what it is. Problem is getting one of them to share the info, anonymously of course.

I would be interested to know if D-Nice has actually tested this fix on his own set(s), and what the result was.

I wonder if it would work for the 2009 V10 65" ?

Yes. You can fix this by resetting the a-board over and over. Annoying, but doable if it gets the black levels back to square 1 for a few months until the next reset. Panny techs can do this whenever they want, but would most likely never share what is involved in order to do it.
- DNice does not care to explain why he is reluctant to share such common knowledge, but he won't.

He probably doesn't want to hear about every Joe-Six-Pack bricking their sets after attempting to do such repairs.

I don't understand the passive aggressive questioning of his motivations. I'm sure he has good reasons. D-Nice does a huge amount for the AVS community -- if he was so reticent to help, why would he publish calibration settings for displays when it (theoretically) directly impacts his business as a calibrator? Most calibrators would never share settings publicly because of selfish motivations (trying to attract paying customers).

D-Nice certainly isn't gaining anything by keeping his mouth shut here. If he refuses to share this info publicly I'm confident he has a good reason for doing so. I know it sucks for those of who hoping for a "silver bullet" to fix the problem, but he doesn't really owe you anything.

Well said

This isn't a silver bullet. It's a standard procedure the needs an explanation from an authorized panasonic tech. Nothing less, nothing more. It temporarily solves the problem. If anyone has access that is "willing" to discuss this super-top-secret-ultra-sensitive process, please let us know.

Until then, whatever.

Like what? What does he do that is so great? All I see is his posted picture settings that won't be accurate due to unit variation, and are largely inappropriate for most viewing conditions (eg. 26ftL @ 2.2 gamma on the ST30). And then there's his break in slides which are completely unnecessary and actually pose more of a threat to burn in. I suppose he does provide black level measurements which are useful, but others like Chad B and David of hdtvtest do this as well, in addition to their written reviews.

It doesn't affect his business due to unit variation. Plugging in someone else's settings off the net simply doesn't work. If anything his presence here attracts more customers. Not that there's anything wrong with that.

Agreed, though it raises the question why he would come forward saying "I have the fix but I'm not going to tell you" in the first place.

Perhaps since the procedure in question is only a temporry fix, that is a reason it won't be shared. I'm thinking that if the voltage increases are necessary and you keep resseting the A-board firmware that you'll end up getting to a point where there might not be enough voltage to drive the panel properly. It has also been said (don't know if it's true) that there are massive color shifts without the voltage increases.
