I'm very sorry to see that you're having problems. It could be repairable, but we'd refer you to an authorized service center in your area to see what the cost for that might be. Here's the thread where you can get details on setting that up: http://forums.cnet.com/7723-13973_102-542437/service-issues-click-here-for-help/
All of a sudden my Samsung TV has developed vertical lines - greens, pinks, purples etc over the entire screen. You can still make out the picture behind it a little bit. Whats interesting though is that you can see the menu perfectly over all those lines. I have checked multiple inputs and they all have the same problem.
Any thoughts before i go out and buy a new TV?
