One, stop doing whatever it was that caused the IR. Two, watch full screen content until it fades away. There are also a handful of other things to try but I've not seen any indication they work any better than viewing full screen content.
If you call Panasonic DON'T make any mention of burn-in or image-retention. Refer to the issue as a "screen irregularity" or "non uniformity". There isn't much you can do if a tech shows up and classifies the issue as burn-in, but you certainly don't want to start out by telling them that it is.
Here is the conclusion of my story. I wrote Panasonic specifically mentioning I had a screen irregularity and sent some pics. Based on the pics, their techs authorized a local tech to come down. They actually ordered a new board thinking that was the cause. When the local tech came and looked at the tv, she immediately said the issue is burn-in without a doubt and that it would require a panel replacement. In addition, she notice that there was a dead/stuck pixel (something I never noticed) and that there was slight banding (none which bothered me) when I showed her white test slides.
Needless to say I was pretty bummed to hear it was burn-in but not surprised. The tech said she would try to see if she can get the panel replaced under warranty, but said not to get my hopes up. A week passed without any update so I reached out to them and the secretary said "Oh yeh, your new panel has arrived, lets schedule a p/u to replace it". They only took 1wk to fix it and return it to me, plus they lent me a loaner TV. The original tech was the one who delivered it back and she said she tried to describe my situation in the worse angle possible while staying true to her findings. She mentioned that they initially declined to do the warranty service because of the burn-in but since I had that dead/stuck pixel and some banding, they approved it.
Now I have my brand new screen going through some slides. Needless to say I'm on cloud nine. So my final piece of advice is to be extra nice to the techs. Offer them drinks, food, anything to help make their long day a bit better. In return they just might take that further step to help you like she did for me. And don't watch with CC all day long!
