Does it happen on all inputs?
Sometimes it can be an issue with a cable/sat box or the transmission of the programming, but if it happens while you're watching movies on a different input, then it is likely a panel issue.
If you get it on more than one input, I would definitely get it checked, especially if you're under warranty.
Hello everyone... I have a Samsung plasma 5054, which is about 8 months old. Recently, I have noticed a white discoloration on the top left corner. This is only noticeable when the screen is really dark. I would say the image has to be black to see it. I don't think it is a burn in issue, since I can't see it when I put the white screen or the scrolling screen. Although, this is not something I see all the time, it bothers me to see that white spot when I change channels and at times when a show or movie is really dark. Should I call Samsung to send someone to check the tv, even it is not that noticeable all the time? Any ideas about what could this be?
Thank you for your input....
