Re: Samsung 59" PN59D550 Plasma - 2011 Model - Small green/orange vertical line

I have the same tv with the exact same problem. My tv is almost 3 years old and it has vertical lines. About a month ago the lines would only stay 10-15 seconds and now they stay on for over 5 minutes. They seem to go away after the tv warms up, but I am sure it is only a matter of time until they stay on for good.
