My first post here - I'm not sure if this belongs in a better place - my apologies if it does.
I've had the Panasonic TC-P60VT60 for a few months now, and have just noticed what appear to be little reddish squares towards the bottom of the screen. After investigating, I'm pretty convinced it's come from the fact I watch a lot of Apple TV with closed captioning turned on. The little red "squares" are actually where the closed captioning letters have been appearing - and it's more pronounced in center and gradually clears up towards the edges (most closed captioning is centered). Two lines of the little red squares, too.
I wouldn't have thought closed captioning would do this - but it has. I can post photos, if it helps. It's fairly faint, but I've noticed it a few times recently and thought maybe it was just an effect in the show I was watching. Not so.
I've now turned off closed captioning, and will be using it as sparingly as possible going forward. Other than that, is there anything I can do to help remove the burn in? Do I use the screen wipe feature? If so, how long do I let that run? Any help is appreciated.
