Reason enough for Panasonic to take back the set. I must admit that even though I know the VT50 is tv of the year, I still had so many problems that I am not sure what to do next in regards to choosing a new tv.
Here's your pictures. If hope you agree this is something to complain about.

Yea. As in they are 100% certain it was permanent BI. As was the manufacture/store that took it back. (according to them).

So your saying everyone is lying ?

Look above. Believe me, many more where that came from...

So far for me, it seems about 50/50. 50% of people see (or admit) they see IR. 50% don't. As far as BI, the case is definitely not as much I agree. But it is there. 20/80 ish

That said, you will be happy to know we are doing as you and nastld said and I said I would. We now ignore IR, totally. Though it is there and we see it, I no longer worry about it turning in BI, and we just ignore it. So far so good ! Your right. It just takes a while (days sometimes) to change from one IR to another or none. Once one IR is gone, there is no trace of it. So, I admit, so far you are right. In my case though. I can not speak on others. And lets admit, I need to do this for a while before I feel test has proven anything.
With that, I also think it is slowly getting better with the IR. Its like the more hours on it past 200 makes the IR not stick as much. Interesting. But again, I can not really verify this. I am just thinking this is what I see happening. And I'm happy about it. Just ironically though, we have been watching way less History Channel lately. BUT once we go into a history channel fest for a few weeks like we do sometimes, that will be something to report back to you guys on.

And seems like you had a weird problem.
From the location of that logo, that couldn't possibly be a "channel bug", so something clearly went wrong for that to get "stuck" on. I'm not sure what that logo even is. Some intertitial logo? Whatever it was, I'm glad you got it taken care of.

After about 50 hours, that had mostly gone, and was invisible by 100 hours. So, as long as you are within the return period, I say give it a chance to clear up.

TIA.

So it is hard to pick a new tv, I am inclined to buy another VT50, I mean how many times can I get a defective unit? Regarding the logo, it is a tv channel logo for a Dutch tv channel.

How long after playing other content did you take the photo?
As a hobbiest calibrator, I have to be mindful to not leave the multicolor pattern on the screen while I'm getting setup. It'll do the same thing but does go away in a few minutes.
If my memory serves me (low chance) it seems that my Pioneer plasma did the same with the patterns.

Hi Everyone,
So I finally pulled the trigger after over 4 years of research of different panels, in store demos, tinkering with picture settings, etc for a 65vt50 at Best Buy. I get it home last night, mount it, turn it on and go through the initial settings and start watching tv (att uverse hd).
4 minutes later...the screen goes blank and I get 7 blinks of the red power light...I search google and it turns out this is a known issue on Panasonic plasmas..some say its a few different boards but I see most point to the SC board needing replacement and a firmware update.
Needless to say, I am pretty disappointed that a brand new $3200 television malfunctions after 4 minutes of use. This problem is repeatable. I leave it on for 4 minutes on any input (including a slide show on usb) and the screen blacks out and the red light flashes 7 times over and over.
Has anyone else experienced this as well? I am now second guessing my decision to go with a Panny since I was looking at the $5k Sharp....or should I swap it out for a later mfg date and hope for the best?
The mfg date is July 2012 / model TC-P65vt50 / serial starts with MJ2213XXXX
Any input is appreciated!

A few examples

But I had friends here when it occurred, they noticed it first, I told them no worries it'll be gone in 15 minutes. 2 weeks later it was still there. Panasonic took back the display. I take alot of care to prevent IR/BI. But it should not happen with current gen tv's, Burn-in that is. Unless severely abused.

I have looked in great detail at 300 or so movies, and not only is there obvious post-processing, but a lot of not-so-obvious. And, I have learned how to apply some post-processing that will increase the compressability by large amounts with little to no visible effect on a moving picture. Why some studios haven't been able to do the same on every title is beyond me.
I have also learned that without control of the mandatory de-blocking in H.264, you can get wildly different pictures from different decoders (or the even the same decoder with different de-blocking parameters). This can be one reason why people with very good displays might have wildly differering reviews of the same Blu-Ray...there is no control over the de-blocking in their hardware player.
It is very, very hard to do anything in real time that works for all different kinds of poor sources, especially when the processor doesn't have access to the raw MPEG data (which helps with motion recognition). A simple temporal smoother costs me 30% of rendering rate on a fast Core i7, but it does give me much better compression (which, for this sort of filter, means that some of the stray pixels that differ from frame to frame are getting fixed, which greatly improves the perceived quality). This sort of filter is very good for below-optimum-bitrate sources.
A GPU-accelerated FFT causes about the same loss of rendering rate but does an even better job at removing noise. But, I doubt that TV manufacturers will be throwing that kind of hardware at the problem, as the fan noise alone would drive many people nuts. Unfortunately, the drop in rendering rate that either of these techniques cause is enough to fall out of real-time.
As for over-compressed video, nothing can truly help it. The techniques above can solve problems with the erroneous high-frequency bits that remain after such a compression, but blocking, smearing, and loss of detail can't really be undone. A "blind" deblocker can do a little, but not enough to really help. Any sharpening without first applying some of the above types of smoothing will just exaggerate the noise without doing much for the rest of the image. With some trial and error based on experience, I can come up with a set of operations that does about as well as you can do, but again this is not something that can just be successfully applied to every source, nor will it run in real time on the sort of hardware available at reasonable prices.

I actually thought you should return the TV, not ignore the IR. Maybe that's not an option for you, which I guess is too bad.
I think you should be 100% happy with your TV, and you are not.

Just had my replacement TV set up, it has the same problem as my previous one- was wondering if anyone has had this issue- I thought it was panel specific but since I got two in a row I'm now curious. It is probably best described by looking at the pictures below, but where ever there is white text on a colored background, I get dark lines that extend horizontally, at first I only noticed it on moving pictures but now its pretty obvious on moving pictures if you know what you are looking for. It happens on any source including Vierra content (pull up a trailer on Youtube, the Bourne Legacy Trailer 2 is a good example, when the green "PG-13" screen shows up). It seemed to get worse on my first panel, but this new one (whole new set) has it pretty obviously right out of the box.
The repairman saw it before he left and is going to contact Panasonic and see what they say, but just wondering if anyone else has this issue or would mind checking it out, I'd appreciate it.
My previous set also had some pretty bad image retention, from things like Pandora on Vierra- I would not watch it for a couple of days and it would still be easily visible on other content. My first panel also had three bright spots on it, not stuck pixels, they were probably 4 inches in diameter, those are resolved so with the new set- well we will see about the IR.

This was kinda sad, the *original* real black filter was VERY good (the one that peeled). The one they replaced it with and continue to use to this day isn't quite as effective and has some side effects which didn't exist on the original. Ironically the TVs they show at CES (even in 2012 a year later) use the original real black filter.
Your post is basically spot on though. These forums are frustrating unless you just want to get settings/help or praise your TV. Lots of passionate people who have way too much of an personal attachment to their TVs. It's a pile of plastic/glass and silicon, not a family member. There's not a lot of constructive unbiased info in here to be honest. You have to filter through the posts from resellers, purists, enthusiasts, Panasonic fanboys and then the "I'm (always) right" people. You'll have gone mostly insane by the time you achieve this

My opinion differs with yours speaking in terms of high end video processing in a TV or AVR. ASICs can be made to do a lot of what you describe without the need of a an expensive GPU...The last chip our division made had inside it 2 ARM processors, 6 core programmable DSP, and a crypto ASIC.
