Panasonic Burn in?

IR is common and what you are seeing, dont worry about it.

Burn in and IR are two WAY different things, and most people confuse the two.
 
I think his case of IR is a little to the extreme side though. I have had slight image retention before, as you say that is common, however it has never lasted more than a minute, and I do all of the things that Hemi mentioned. I play video games on it, watch news channels with tickers, espn, ect. Change the channel and the IR is gone.
 
My 2008 Panny would display IR sometimes 30 minutes after a static image was displayed for awhile, but it always went away. You don't see it in normal viewing, so IMO, IR is just a non issue, even at 30 minutes.

You'd have to be abusive to cause burn in.
 

Agreed! I've caught my wife pausing shows for an hour or more (pause logo and all). I could see the IR but not during normal viewing. The next day I would turn on and couldn't see a trace of IR anymore. I lovingly tell here to keep doing it so I can justify a new set with 1080P resolution and more HDMI ports.
