I am glad to hear that

I cannot believe that Panasonic will not recognize this as a problem and do something about it. They sure are funny about stuff like this. They fixed the FBr issue with ST, GT and VT series but failed to do anything with the S series.

I am grateful that my green blob is very faint and does not show up in regular viewing. My pink is on the edges, moreso on the left. All I can do is pray that it diminishes with time, as Panasonic obviously will not do anything about it, which is crazy. I won't even bother to call, because if they tell me that I am too picky, I will get pissed off and return an otherwise excellent tv.

Not all the 2011 panny's have this problem. Mine shows no sign of this at all and I think I'm hue sensitive. If I have time tonight I'll take a photo of my tv and post. The pics shown in the forums look like my 27" HP TN panel on my main PC which looks like pure crap compared to my sony pro monitors.

I passed this hue test with 2 wrong using my TN panel, I think my CRT's would have helped.

I am a new 55ST30 owner and am keeping my fingers crossed on my panel, so far havent seen any blobs.

Well, that is good news! Did you run the break in slides? I am wondering if the slides are perhaps causing the blobs?

No, the slides are not causing the problem.

Only have P&S camera, but I will do my best.

P.S currently at work but will try and get some photo's asap.

One of the dark grey break in slides.

It's not the slides-- the slides are only a tool to help safely age the panel quicker.

Not wanting to hijack this thread but might you give some impressions of the ST50 in terms of panel speed, black level and gamma characteristics. I'm finding the official threads to be 99% speculation and conjecture.
post #41 of 78
Sure. The short answer is that I find the ST50 to be a big step up over the GT30 in almost every respect. Black levels are excellent, color accuracy is much improved, line bleed has been significantly reduced, gamma is excellent, and there are no uniformity issues that I can see. I'm very, very happy with the panel and wouldn't hesitate to recommend it.

I spoke with the service company that is coming out Monday. The tech said that they hadn't heard of the issue and they took it to the Panasonic rep and he hadn't heard of it either. The Rep then took it up the chain until they spoke with Panasonic UK and they are getting the firmware fix from them. I have read on AVForums that the fix has had mixed results. This is better than I had hoped for and I will see how it plays out Monday.

Thanks for the reply!

I've actually been quite happy with the black levels and color on the S (although I'm always down for a deeper black! ) The ONLY complaint I can seriously level against the S is it's incredibly eff'd up gamma in anything other than cinema (which is only suitable for dark room viewing IMO). This seems to affect the picture modes of the ST30 and GT30 as well but, unlike those models, my panel eschews the "pro" picture mode settings that allow you to better tune gamma.

The result of this poor gamma is uneven skin tones, poor shadow detail and severely crushed whites-- again, outside of cinema. It is ridiculous that Panasonic wouldn't include advanced picture controls on this set regardless of it's price or intended consumer. Yet another example where Panasonic has dropped the ball for no good reason. I hate to say it but the fluctuating brightness and green blobs have soured my opinion of a brand that was already fairly tarnished as a result of the black level rise on my 2008 panel.

Here's some pic's I just took of my 50ST30. The uniformity looks good. I'd consider this normal. You can see a little IR on #4 from the slideshow preview. #5 is my PC monitor, it's a TN panel(yuk!) lots of orange on the sides.

I see absolutely no discoloration at all on my 65VT30 October build, but who knows. I'm very anal and have inspected over and over again against different full screen colors and see nothing at all wrong with the set. It's seriously as perfect as perfect can be.

Glad to hear you got a good set there, dpippel. I've only read one review so far that claimed they saw a tiny hint of screen uniformity issues, on a 2012 Panasonic, but it was very very faint. However, it won't suprise me at all to hear some reports from users as QC if/when it starts to slip here and there. (just like with last years Pannys.... Also there have been a few Kuro users reporting the blob issues. )

It depends on what your settings are when viewing the slides. My green/pink isn't really visible on the slides either, as mine look like yours. My green is barely visible at all and I am hoping that my pink diminishes.....

Looks like it is much improved over your first one, to say the least. What you have now is probably very similar to what I have. My pink is more noticeable on the left edge than on the right and it is only the pink that affects the picture when viewing any content. Here's hoping our pink diminishes over time
post #50 of 78
I tried a different setting from the DIY thread and I had my contrast turned to 100. I saw the dreaded pink and green tint on a white background. I turned my settings back to the "Jimmy" settings and it went away. Is everyone only noticing it when the contrast is turned up?
post #51 of 78
I assuming you were in custom with your contrast up at 100, since Cinema doesn't change much until under 50. So let me ask, what Picture mode did you crank your contrast in? I will try this...
post #52 of 78
Below are the settings where I saw the Pink/Green tint. Someone had posted these in the DIY thread and I tried them for kicks.

Custom
Contrast 100
Brightness 56
Color 35
Everything off/ zero black extension
Color temp normal
gama 2.2
panel brightness on high
tint to +13
hi-red to -13
the rest was the dnice settings in the pro settings.

Panasonic called off the service center appt for my set today. Instead they are sending one of their regional Reps out Wed after doing some more engineering research to apply the firmware update.

I can't really see mine in the slides for some reason. It was only a particular PS3 background that made mine visible. I will try the settings you had and see if I can see them in the slides. It takes a certain shade of light grey in viewing normal content where my pink blob is even visible. It is rare that I see it when the tv is viewing content, so mine is pretty mild, I would have to say. I typically watch in Cinema though and my contrast level is 85-90. i will play around with it and try to make it stand out more.

Mine is nowhere near as bad as Sage's first set was. Thank god. I am going to be keeping mine, and just hope that the pink fades some so that I never see it. Right now the green is undectable in normal viewing and the pink is rare.

The pink tint on my 65ST30 has improved significantly as I've reached around the 1000 hour mark or so.

I really hope that happens to me, because right now that is the only thing about this tv that bugs me. Even though I don't see it that often, just knowing it is there sucks and makes you look for it.

Ditto.

The Green BLOB on this latest 60" ST30 has all-but-disappeared - around 500 hours now - however, the panel keeps a nice Green-Substituted-For-Gray at certain levels of Gray scale, and PINK TINT remains visible in some scenes as well - although MOSTLY only during B&W content (will show up in some "dirty whites" if they are displayed near edges of the screen: fog, med-dark clouds, and LAB COATS - think HOUSE for the latter....).

Nearly 5 weeks until Final Decision Date...

Would be very interesting in learning what they say - and, particularly what they DO (if anything), for your panel....

A few shots of my Panasonic 55ST30.

While the Green and Pink is not visible to the naked eye on my Panny. It does appear that in Paint by zooming in I can see the green and Pink botches all throughout the Panel. I need further testing to see if this is the nature of zooming on an LCD. Will check my CRT monitor in bedroom and do some comparsion shots of my old Panny S1.

P.S this is all for fun, nothingmore

Update: I guess zooming in doesn't count since I can see green and pinkish botches on pretty much any type of photo, family pics, etc. And I stand by my original point of view that not all the "2011 Panasonic sets exhibit the Green blob and Pink tint" , on the other hand it's very obvious some do.
