It still amazes me that in this day and age TV stores don't take better care of their floor models. I mean, everyone knows about IR. How can a manager not make the effort to ensure 16:9 content is run on all TVs--even the LCDs--7all the time? This just boggles the mind.
I pretty much agree with everything you said. How do the people running these stores take no precautions? I think the risk becomes worth it at some point. I guess that point is what I'm trying to identify.

Pretty sure we've already had this discussion. Not talking a full blown calibration, just picking a Color Temp setting from a pulldown of maybe a handful of options. I can eyeball when grey has the least amount of coloration to it. Be happy to show you.

Also, my set before it hit 1500 hours was very very resistant to IR for any content....now its nearing 1600 hours and I can make out IR from just the menu after I switch to a white slide but it fades away after content is displayed. Im guessing at 1500 hours the voltage levels jumped keep up with aging phosphours or something...sorta like what happened with the VT25 black level rise when the word was some Panasonic engineer goofed on the voltage algorithm too early and too aggressively
That wouldn't surprise me at all. Seems to be the case for me too, with possibly a bump (or two) prior to that. Pretty easy to get anything with bright lettering to stick relatively easily as of late, particularly towards the bottom of the screen.

But... even when the set was practically brand new I ran into some of the same IR early on when I thought I'd run slides for 100 hours or so. Right off the bat, I think just from running the application to get them to play. (Not really sure it's just IR, so much motion involved in the (video) noise that goes along with it; towards the top I've seen some IR too, but none of the video noise.)

I saw some mild IR on my VT60 from the application to play video and it could not have been on the screen for more than a minute, probably closer to 30 seconds. This was with 1000+ hours on the set.

I see IR when I launch the PS3 Amazon Video app. It's up for just a few seconds and it fades pretty quickly. My old Samsung plasma did the same thing. I don't really consider short term IR like that a concern.

My IR still does seem to fade, but seems like it's there with the slightest provocation now, so as one bout is fading another comes along to take its place quite readily. Contemplating just making it a blu-ray/dvd only panel (but in the real world...)

At least it is still "only" visible/present with 16:9 mostly light/white content (black bars on the side, per 4:3 content, invisible; darker 16:9 content mostly always invisible, but sometimes if you look...).

I'm in the same boat with my plasma in regards to IR, its just an ST60. I have 2800 hours on it and run contrast on logo'd channels at a modest 60 and it will still generate IR no problem almost instantly. I also have line bleed pretty good on the low and mid brightness settings but when I put the panel brightness to high it diminishes it quite a bit but I normally run in mid or low cause of the image retention running in "high" seems like it sticks around longer. Sometimes even a persons eyes create slight line bleed.

I too was thinking maybe the voltage has become out of whack but is that normal? How does that even happen? I nervously went into the service menu to check my VSUS but it said it was set to low, was hoping it was set to high or something that would explain it. Not sure where to go from here. I'm passed my warranty and don't really want to pay for a tech to come out if its gonna cost over $50 or so. The only thing I could think of at this point though is that the voltages on the back of the panel are set too high or something. Not sure. It's aggravating.

I wrote panasonic on twitter about this and they told me its not normal (obviously). They want me to take a few picture examples and send them to them and they will share with their tech team. Gonna do that at lunch. I'm sure they will look at them and say its either "within normal operating guidelines" or something to that extent. Ideally I'd like for them to send a knowledgeable tech out for free to check the voltages.

Even as it stands its the best tv I've owned and don't plan on getting rid of it till it completely craps out.

Any recommendations other than Sanus?

Thanks!
When I got my 65" ZT60, I gave my girlfriend my older 50" V10. That weighs 75 pounds and we used a Peerless fully articulated mount. The installation went smoothly but I was just installing into two studs behind standard drywall. The Peerless was a bit cheaper than the comparable Sanus model and was really well built.
