Question about Samsung PN50C450B1DXZA 50-inch Class Television 720p Plasma HDTV

Open Question

Thick horizontal line in middle 1/3 of screen

We were given a Samsung 50" Plasma pn50c450 - it has a tiny crack in the screen and a thick black horizontal line through the middle. Picture on top of and bottom of line. The middle 1/3 has no picture. We don't have the remote and don't want to purchase a replacement yet if the TV isn't fixable. We were told it was hit with a Wii remote. Is this line a fixable problem, what could have been damaged? We know nothing about plasma tv's..... It's almost like a bulb being out on a rear projection or DLP tv

SOURCE: Samsung Plasma TV - picture has 6 sections of horizontal lines

All I can say is when you watch T.V. the plasmas run off of plasma gas and when you leave something on for so long it burns in the screen. I have the same T.V. and when watching like the weather channel it leaves lines but they go away. If yours are permanent then you can't do anything, but it may help if you go on your remote and go to "menu" then look for "setup" and scroll down with the arrows on your remote. Look for "screen burn protection" and select "white screen". This will make your whole screen white and it may take out the lines. If you let it sit white it won't hurt it. All one color won't hurt, the only thing that hurts is like bright white lines in front of a dark background. Just give your T.V. a break from time to time ESPECIALLY ON VIDEO GAMES. T.V. shows that are HD usually have their channel icons that move or are very dim and they won't hurt. Just go to what I told you and let it sit about 20 minutes, if that doesn't help, then the T.V. you have i believe comes with a 2-year standard warranty and if it's under warranty take it back if you have the reciept. If no reciept then call 1-800-SAMSUNG.

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.
