Panasonic 11G/12G/13G black levels have seemingly doubled overnight? - Page 106

he also seems to have an obsession/ thing for mentioning food products in his chats...maybe he is on a diet and thats why he's so cranky....

Can someone tells us clueless people here how to test the infinate black in vivid mode. I mean, we have to get a base setup on how to do this. May it be a black slide on a dvd, usb device or just a blank input screen as an example.

We'll get back more reliable feedback if everyone does it the same way wouldn't you think?

I don´t know anything. But I know one finnish guy who measured 0.026cd/m2 from his 50C10 which is cheaper model than X10.

Thanks to this thread I just cancelled my order for a G15 placed last night.

Does anybody have any other recommendations for a 46 inch TV?

That's about 0.008 ftL. Not an unusual number for a new set.

BTW, Panasonic has never publicly released any MLL spec numbers -- for any set. And there has been talk about law suits and recalls.

I agree panasonic has never released any specific number stating what the black level should be... I personally can't see a lawsuit happening either.

In the meantime, I guess I'll sit tight and hope for the best with my TC-P46-S1.

I do know however, that no backing by panny equals no more plasma for me.

Ditto all that!

I don't remember seeing any MLL specification from Panasonic either. But they do advertise the contrast ratio. Regardless, if Panasonic doesn't come out with a fix or refunds at least for some owners here, I don't think a lawsuit is without a merit. Whether you get enough money after legal cost is another matter.

Well Panasonic's official position on this is the following. They;re going to try to ignore this issue, or maybe again this is a cover while the investigation is ongoing. Discuss.

Rennie C: thanks
Rennie C: there is some information that just came in today that should explain the black level.
Rennie C: here it is
Rennie C: Panasonic VIERA plasma HD TVs deliver exceptional picture performance throughout their lifetime. Various elements and material characteristics of all electronic displays change with use over time. In order to achieve the optimal picture performance throughout the life of the TV, Panasonic VIERA plasma HD TVs incorporate an automatic control which adjusts an internal driving voltage at predetermined intervals of operational hours. This results in a more gradual change in the Black Level over time.
As a result of this automatic voltage adjustment, background brightness will increase from its initial value. After several years of typical use, the internal material characteristics will stabilize and no additional automatic voltage adjustments are required. The Black Level at this stabilized point will yield excellent picture performance

My suggestion would be:

1. Get a source material that you know for sure has a complete black screen. Use HDMI input for consistency. Free and downloadable AVSHD disc for BD player is good. Use the 0% IRE window or field pattern that comes with it.

2. Play the 0% IRE pattern. Don't pause it because the BD player may add the pause indicator on the screen and defeat the test purpose.

3. Switch between the view modes in dark room. Vivid mode should detect the complete black input and turn off the pixels completely. Other modes should give some sort of gray black illumination.

Attitude??? Are you serious??? You!!! You work for them!!! Did you not read that whole interaction? It sounds like you may be the one with comprehension problems. Let's take a new poll. Whoever thinks I am the one with the problems after reading that chat please post in Chad's favor, and if you think Chad needs improved reading comprehension skills, well, I will personally work on them with him if he would like providing I get enough votes in my favor. For goodness sake she couldn't find out if the freakin bezel could be removed which is a no brainer.

OK, here's what I have so far. Based just on what I skimmed in this thread for testing using Vivid mode.

54" G10, 725hrs - Vivid mode did NOT go to deep black.
42" 85u, 2700+ hrs - Vivid mode did go to deep black
42" 85u, 2750+ hrs - Vivid mode did go to deep black

What gets me about their statements is they say the levels will change gradually over time, yet people are experiencing dramatic, overnight changes at random operation hours (and I think some have had worse IR start at the same time?) and that this is very abnormal compared to what Panasonic says happens. I know they're just trying to dismiss the issue but it seems to me that Panasonic's statements don't cover what people are experiencing and there could still be a case against them. I guess this is pretty obvious but it's been bothering me not knowing since I'd really like to get one of these TVs otherwise.

Ass.

Dude, quit now, while you are behind.

not sure if you noticed but about a half dozen people posted to comment on their severe disapproval of you, and approximately zero people thought your words or attitude were appropriate. so I am afraid you are going to lose that poll, those poor CSR's deserve better than to have to deal with crap like you gave them. you can scroll up and read those other posts if you want to know what the consensus on your behavior is

you aren't helping...

I've gotten frustrated with CSR's at various companies and acted out of line (hello D*). Every time it was because I felt like they were intentionally trying to rip me off or get out of providing a service. And even then I didn't resort to name calling. It didn't even seem like you were contacting them about something that was harming you in some way. You just started ripping into her because SHE DIDN'T KNOW. Some advice that I've learned over the years. You get what you want a lot more when you are nice to people.

Oh and I vote no

another no vote, it's not looking good for Ralph!

EDIT: I will summarize the voting so far below for your convenience. Being a man who obviously believes deeply in democracy, I am sure you will concede that you acted like a jerk and were totally inappropriate, and hopefully take a step back and examine the way you treat other people.

EDIT 2: It's either 11-0 or 10-1 depending how you count dchaves response. Shall we call mercy rule?

Just wanted to personally thank-you you! Your Denon to English works have saved me hours!

I have to vote no. She wasn't rude at all despite being baited.

Okay, well if it is permitted to start calling people names on this thread then I think I may have to start hurting some people's feelings. Seriously though why do you get your panties in such a twist? That company feels that it's okay to screw with it's consumers and release that ridiculous statement that it is normal for thier sets to break in a relatively short amount of time, then employ "technicians" that do not understand the OUTER workings of the products that they are paid to service and have knowledge about, but it is "HARASSMENT" for me to screw around and have a little fun with their IDIOT staff when they don't know what the hell they are talking about. They get paid to sit in a chair and tell you whatever they feel like saying apparently as I have seen chats on this thread where they completely contradict themselves. "Oh yes, the firmware on 2/5 is the fix for the black levels. Oh but that fix for the black levels is actually not for the black levels but it is for yellow and green THX problems. I know I just said that it is for the black levels, but I am smoking crack and snorting cocaine here at my desk so I am getting confused. Santa clause is working on the fix for the black levels and it will be out no later than Christmas." I mean that is basically what you get in Panasonic chat. How could any of you blame a fellow consumer for being slightly jaded and fed up with dealing with "professionals" with good jobs that couldn't put gas in their own car without accidentally swallowing it?

see my post above -- since you called for the poll, are you going to be honorable and admit that you were wrong? are you man of democracy or some stinkin' red commie?

UPDATE: goofball's post above makes it 12-0 or 11-1. You acted like such a jerk that you even inspired a lurker to make his first post to vote against you!! will you concede?

Edited to remove comment to now-removed belligerent posts....

On with the discussion! :-)

My goodness I did not rip into her because she did not know!!! I ripped into her because she was doing little or nothing to find an answer. It's not like I asked her to explain how anything complicated inside the thing works, I wanted to know something simple and she and her IDIOT tech gave me the wrong info OBVIOUSLY saying the replaceable protective glass panel could not be removed. I MEAN COME ON!!! Poor poor innocent LAZY ASS ****** CSR's. Maybe if they had more movement of their bodies as opposed to being planted in a chair all day their brains would get more oxygen and would work more efficiently.

you have problems. this has now been confirmed through polls. proof!

see my posts above, will you concede? are you a man of honor, you DID suggest the poll yourself?

the issue with panasonic plasmas' rising black levels is very similar to the marantz pop of death

Not sure if your post has been replied to yet, but I found this on HDGuru:


hdguru.com/ces-2010-report-and-analysis-part-2-panasonic

okay to get back on topic...

54" G10 - latest firmware, THX fix, May build date

I can confirm that the infinite black does not work on my tv in vivid mode as described by others. As stated in my other posts, my set suffers from the black level problem as well as horrible IR.

Several posts removed, lets get back on topic guys.

Thanks a bunch Mike.
