My Samsung Plasma just got burned in! (by 3 users)

I stupid friend of mine came over to feed my dogs when I was out. He watched my Plasme tv for a while and when he shut the system down he only turned the cable box off for opprox. 6 hours. I did have th Tv on pixal shift . Know my screen seams grainy in dark scenes . I does seem a little better after a rolling picture screen. How long do need to run the screen before it gets better?

i have a question............ i dont know if this is a burn in problem or not? but my samsung plasma when it is warm/hot approximately 2 hours of tv on, when the screen screen goes black you can see some pixels that dont go fully black until 3 or four seconds later. is that what a burn in is??

also when i turn my tv to an input that has black and white noises the center of my tv has the "no signal" bar up, is there a way i can eliminate that to help my problem??

thanks in advance..

plasma screens have this well known habbit, of burning images in. usually they burn in stuff like channel logos or stuff like the one you mantioned. 3-4 hours of screening the same image will do.
for starters, let it "rest" for a day or two, I dont know plasma screens very well, but in normal TV screens it can solve the problem. if not, according to my knowladge, this is a problem that requires proffecional care, and there's nothing that you (assuming you are an avarage user) can do about it by yourself.

Most samsung tv's have a selection under menu to reverse burn in's. It is under the set-up menu and is titled Screen burn protection select signal pattern and let in run for approx 30 minutes this will "un-burn" your screen. Your manual should cover this or you can call samsung and ask them.

I got exactly the same after playing COD4 on 360.
White Noise for an hour or so will cure it - once it's gone, turn you contrast and brightness down to 50% ish.

I bought a new TV just last week, however I was not told about the Breaking in period of 100 hours, so after playing Battlefield for about 4 hours I could see how much ammo I had while I was watching TV, obviously not what I wanted, so I just got off the phone with Samsung (1800-SAMSUNG). I was told to go to my picture options look for "Screen Burn Protection" and change it to white screen and just let it sit at the white screen for about an hour and all should be well.

Just for reference my TV is PN50A450P1D

I have noticed a line forming down the side of my plasma screen thats closest to my surround sound woofer. So I have moved that well away from the tv and I run the afore mentioned Screen-Wipe routine for an hour. It seems to be doing the trick :-).

the reason why that happened is that was the end of the disk and it was asking you to insert disk 2 so that it could continue the show that you were watching

there is a product that some poeple have used to clean their plasmas called PixelProtection at http://www.pixelprotector.com
