Samsung Plasma Issue?

[Bigblue622]

I bought a 58" Sammy plasma in January and it was my 2nd Samsung. I no issues with the first one and decided to stick with them. Well in the last week I have noticed on a white screen (suck as startup of Xbox) there is a line of purple patches on the top right of the screen. I have noticed it on commercials as well and when I pause it and the DVR pause bar comes up, it disappears. I have tried to change brightness/contrast to see if that helps but again when I bring up the menu, it's gone.

It has two months of warranty left so I have time, however if it's something that anyone can help with I would rather not go without my TV for a couple weeks to get repaired/replaced or whatever.

Thanks.

EDIT: It's a PN58C500. It was the best buy model that was similar to the A550 but cheaper.
