Man I hope I didn't wreck it

Hello

I have a Panasonic 42inch Hidef plasma panel. After entertaining some
people, and having our comcast music choice channel on, I noticed a
burned in image and bars where the 4:3 image stopped. I had it on for
2-4 hours.

Then, a friend gave me advice to play snow on the panel (remove the
input) overnight. Now, ALL low def images (especially graphics) have a
choppy broken look, and the black areas can clearly see shadows from
the snow?! Is this permanent? I am running the white bar scroll
screensaver all day, will this help or hurt? I can't believe how easy
it was to do this. I bought from jscreenfix the dvd pixelprotector,
that supposedly has a pattern like snow and some calibration
utilities. Will this help? I reset the panasonic back to factory
defaults, which seem bright to me.

In HDMI input mode, I cant adjust the gray of the bars. I can't even
adjust the aspect ratio, its 4:3 for reg and fullscreen for hidef.
Every other vid mode can choose full / auto / standard. Is this
whitebar scroll what you mean by "white wash" ? I have it running at
home.. if I could just kill the fuzziness that the snow caused Ill be
happy.

The first 200 hours the plasma is most prone to burn-in.

Hmmm, if this is the case, why wouldn't the manufacturer just run 200
hours HD (or stretched) programming as a part of the process? This
sounds like a major issue to me, isn't it?

Are you saying that watching 4:3 programming after these 200 hours is
OK?

Thanks,

Maybe because that would put a 200 hour delay in his manufacturing line
as well as dramatically increase the need storage and power distrubution
while the sets were under test.

Think about thousands of units all burning in for 200 hours. It would drive
costs though the roof.

What I find disappointing is that I've read the plasma burn problem had been
licked. From the sound of this thread, it's far from licked.

It is for the most part (in the newer models). If people are really
concerned about it - you can set the user setting to 0 (Picture
control mostly) for the first 100 hours, but it not necessary as maybe
it was in the early days of plasma's. If your tv viewing varies (4.3
some HD etc). you don't have to worry. I wouldn't leave it on some
static image constantly like the scrolls on cnn - or some video games
etc. I think that can damage any tv.

The nature of the aging cirve for plasma phosphors has not changed
substantially, but the long term life and general tendency to differentially
age the phosphors seems to have improved greatly. This means that the issue
of burn-in is far less a factor than a few years ago, but the fact remains
that aging occurs much more rapidly early in the life of phosphors and the
rate levels off rapidly. There is good reason to be more careful early in
the life of a PDP.

There has never been a significant problem for people who are educated about
the product and do not run it at full contrast with bars for long periods.
Those who do will still get burn-in.

Good news - running the white bar scroll screensaver overnight has
completely removed all traces of the burned in image from the music
choice graphic. The Right side you can still make out where the 4:3
is, I think I am going to try putting it in negative screensaver mode,
so the bars will be white for a few hours. Either way - I can live
with this. The worst thing about this panasonic from the factory is
they have it in "dynamic" mode, which is absurdly bright. I put it
back to standard, and I have a calibration disc on order to get it
right. I have this tendency to rely on factory default settings but
in this case it really isn't optimal.
