We had someone staying in our house over the summer while we were away. Apparently they watched a lot of 4/3 content on my 42inch Panny Plasma TV. When viewing full screen content, I now see 2 faint white vertical lines at exactly the transition points between the R-L edges of a 4/3 image and the black background.
Set is less than 2yrs old.
Will the lines go away over time ?
Is there a way for me to get rid of the lines ?
Thanks,
Ross

Since our return, we have watched full screen content. As of today, lines have just about vanished and I have to intensely focus to see them.
Feel like I've dodged a bullet. I will look for a burnin and calibration disk for the future.
Thanks. Ross
Burn In is mostly an antiquated urban legend. As your experience shows, your set actually suffered from Image Retention, which is short-term. I see it occasionally on my Panasonic plasma, but it's very, very faint, and goes away within a few minutes.
Amazon.com - look for 'WOW Disney blu ray calibration'.
It's a disc that helps you calibrate your tv. Excellent disc and it has a program on it called a 'bit flipper'. It rolls through your screen turning each pixel on and off. Supposed to help with burn in problems.

The great majority of burn-in issues come from people who have little understanding of display technology and owners who haven't properly calibrated their displays.
Every display technology has its pros and cons. For me, plasma displays have fewer cons than other display technologies and that's why I own them. My kids probably know more about what to do and what not to do with the 3 plasmas in my house than most adults. Some people just don't have a clue, at times no fault of their own, but unfortunately they are the reason for threads similar to this one.
My wife and kids would have any plasma coughing up pixels in a month.
I do not watch tv. Ever. No sports. No cable. No satellite.
I watch movies and tv shows on bluray and dvd.
It's about half movies and the majority (90% I'd say) of them do not fit the screen completely.
I'd have to run a bit-flipper every night to get those movies from burning in horizontal lines on my set.
If you watch a lot of material that doesn't fill the whole screen plasma is not for you.

We watch a lot of movies, of which many do not fill the screen, so we have the black bands at the top and bottom of the screen, but have never had any issues with burn-in (but then we only watch maybe two movies in one night). I would think that to have any burn-in, you would need to watch a lot more than that at one time. Ours is a 50" Panasonic plasma.
It is a 58" plasma and it is a couple of years old too.
In addition to watching TV, DVDs and Blu-rays, we also use it for video games, (XBOX 360 and the Wii).
Never any burn in issues at all.
My guess is that the O.P.'s house guest left the machine on pause for an entire week.
You are a prime candidate for non-plasma displays, especially if what you watch has to be OAR -- no matter what.
The aspect ratio we have now, 1.78:1, came about due to a poor and asinine compromise made by the broadcast/display industry because the movie industry acted like a bunch of snobs (and still do, actually). They basically added an aspect ratio hadn't existed.
And by the way, watch enough content on your new display that isn't 1.78:1 and you'll have a similar problem. It takes a bit longer to happen, but with LCD it's called brown-in: a discoloration (a tannish tinge) of the area of the screen that's most used.
Thanks for the brown-in tip, I'll run my Disney bit-flipper from time to time.

There should be some type of feature to even out the uneven screen aging. I know the broadcast/commercial models have a few sceen settings to mitigate such problems. Hopefully the consumer models, if that's what you have, can do this as well.
If not, there may be a reference disc available which would have some of the burn-in "reversing" patterns. Such a disc could take the place of features not included in consumer models.
