As for IR or any retention at all? Not even a chance. Clean and crisp from day 1. I have driven the wife crazy these first 200 hrs zooming material and avoiding bars, but it was worth it! Now we watch everything in "full" and it is mint :-)

I disagree, I have bought tvs from amazon before. Its so simple, first the price is cheaper, they have a 14 day price match, 30 day return policy (have returned two tvs, to them, so hassle free), you don't have to pay taxes depending on where you live, and don't have to waste gas or energy at best buy with a stock market share of what is now less than 11.00. You won't have to hear their crap about the best buy credit card either. oh! and you won't have to hear about their directv stupid promos!
Mo!

We've had the GT50 since the week after Black Friday. With settings reduced (brightness contrast), we watched a variety of content and ran the slides while sleeping or not using the TV (not while away). In all, I would guess we've had the slides running 225+ hours. Mind you, this doesn't include normal viewing.
Last night, we had an emergency with one of our dogs and had to rush out of the home for about 20 minutes. I left a copy of Dead Nation running on the PS3 (screen dimmed to under half brightness after a few minutes), when I came home I saw what I assumed to be IR. Immediately, I ran the slides for the rest of the evening and all night. This morning, the image is still clearly visible on almost all slide colors.
At this point, I still notice it even during a Bluray, I am inclined to call this burn-in. Seeing as how I have a 90 day return with BB, it's going back. I am not going to curb my viewing experience for marginally better blacks and absolutely no other perks.
If I cant leave something on this TV for 20 minutes, how the hell do you watch a movie with black bars?
PQ was great, as it is on virtually all high end TV's...

Hard to believe burn in after 20 minutes. Perhaps you have some wierd lighting or shadows in your room that you haven't realized. I'd suggest you give your TV a break and lay off the all day and night slide running, and see how it looks after several hours of being totally off.

No IR here. But then again, I came from the VT10 that IR'ed everything.

One unfortunate side effect of the slides imo is that people are evaluating picture quality, uniformity and traces of IR based on slides. It creates alot of unwarranted worry imo, 95% of the stuff you see on a colored slide you will never see in real world content. Obviously channel logo ir, ir from huds etc that you can clearly see while watching blurays or tv is an exception to that. Also people have the mistaken belief that running the slides makes their sets impervious to IR which is not true at all. My advice break your tv in however you choose and this just watch and enjoy, hunting for flaws never turns out well.

You tell me, it's suggested on virtually every other plasma thread (exaggeration). As far as obsessive-compulsive, I simply pushed the SD card in when done viewing content, then turned the TV off when we left the house. This, again, a recommendation virtually everywhere on these forums. So no, not obsessive, it's just clearly a strong suggestion almost everywhere I look.
As far as 20 minutes, it's not for me to convince you. I purchased this TV, tried it and these are my results. I am not pushing anyone to another brand or TV type, just saying that a plasma TV does still get IR and burn-in. It's not a myth, it's not based on old knowledge or tech ... it is still a very relevant issue today. Trust me when I say, I am as shocked as you over just 20 minutes.
Yes, the TV is currently off (at work). We'll see after a 9 hour rest..
Yup, that's exactly what I said. I came here, said everyone is lying and left. My post is absolutely horrible and is a mark against you fine people.
Give me a break, I am an honest owner who feels duped by misinformation from not only manufacturers but forum members. One member swears about a break-in period, another says is obsessive. I followed directions as best I could and these are the results I got.
If you want to cry about my post and make it out to be more than it is, go for it. Flag away and get my horrid post removed.... :/ I think you're just upset because I am right, but whatever...
And what official or unofficial document discloses that info? Between all the posts here and on Panny support forums, no one knows what the real solution for any of this crap is...
I was not putting on slides to find a problem, simply prevent an issue for leaving a semi static image on for 20 minutes. Yes, I still see the IR/Burn-in the next morning viewing regular content, that is what bothers me. Maybe because I know what I am looking for, my eyes find it easily. The point is still the same, with a plasma I have an issue where I can see a retained image on my normal program viewing. If I could not see the image when viewing regular content, I wouldn't have much of an issue. I say much, because it technically still is an issue. Comparing an LCD to a Plasma, you'd never see a situation remotely like this.
If a 20 min image is an issue great enough to see it the following day for any reason, it stands to reason that watching a Bluray (w/black bars) for 1-3 hours will serious mess this thing up.
Anyways, remove my posts or do whatever the hell you want. This is my 2 cents towards plasma tech ... or at least the GT50. So I have no further business in this thread cause my TV is being taken back ... SEE YA!

It is only noticeable on white and light grey backgrounds, but i am now starting to notice it on some regular content. It shows up as a hazy yellowish tinge. Almost looks like IR from watching too much 4:3 letterbox content, but I NEVER keep side bars. Its not completely solid bands or lines (like some have reported) all the way down each side. Its blotchy and worst in the far right middle portion of the screen. I have been overly cautious (content wise) with this TV and have been babying this thing since I got it, so I don't think it can be related to IR/burn.
I'm trying to decide if i can live with it or not. If it gets any worse I will def be doing something about it.
Has anyone else had or heard of any issues like this?

The fact that they are not burn-in or IR slides would be a big hint. They are for uniform aging purposes to some degree, but have never been for burn-in. They are to get you past those first 100-200 hours when things stabilize and you can perform an accurate calibration.

They may not be "burn-in" slides but most sources I'm reading on the internet say that the first 100 hours on a plasma is where IR and burn-in have the greatest potential. So with that in mind, wouldn't it make sense to use them help get through those first 100 hours. I mean I could watch movies but oh yeah there's black bars so we can't have that. I could play a lot of video games but no there are HUD screens to watch out for. Ooooh I know, I'll just watch my favorite channel on TV...oh I shouldn't do that either because the channel logo is static. So in a sense aren't those solid color slides good for getting you passed the 100 hours where the set can be more stabilized for other viewing enjoyment and not just calibration? It seems to me like those slides are one of a few choices we have to get through a 100 hours or so of use other than watching zoomed in shows or other full screen content. I'm a new plasma owner but these posts where there are members putting down other owners and making them feel dumb for using slides for anything other than a D-nice calibration seem rather harsh especially since what content people watch after a D-nice calibration won't be the same anyway.

Sure, you can use them for whatever purpose you want. You can also just watch movies and/or television shows that fill the screen more frequently in the beginning. You can choose to vary the content, display solid color fields, whatever you want really. I'm just saying that those slides were produced for one purpose, no matter what else people may decide to use them for. I myself chose to be mindful of my Contrast setting and vary the content I was viewing.

I do understand what you're saying. I guess it's just easy to pop these full screen slides in on a loop when I'm sleeping so I get through this break in process as fast as possible. I certainly didn't buy a brand new wide screen TV so I could watch zoomed in content for the next month or so.

Some people are too literal, and assume that if they used the "anti IR slides", they no longer need to balance their viewing habits to counteract the effect of fixed images. In themselves, the slides are not protection against IR. All they do is age the phosphors. Any good 1.78:1 (16 x 9) aspect ratio movie will do the same thing, and in the case of high contrast vivid Pixar animation movies, they do a better job of removing any IR that might occur.
