Sounds like a bad connection on a ribbon cable or plug comming or going to the LCD display. This is something you should not try to fix as these circuits are very very fradgile and you can easily break or tear a ribbon cable . Call the manufacturer to get a tech to assit you. Good Luck

yes. sorry to deliver bad news. cost to repair is 90% the cost of when you purchased. panel is around 400-500 plus your labor. samsung may have flat rate program but still is not very economical. sorry again.

The reason for the green lines are the resolution. I'm assuming you're TV is set at 1080i, not 720p or 1080p correct? What happens is the "i" stands for interlaced, meaning, your TV displays your images with scan-lines. The "p" stands for progressive, meaning, TV displays picture as a whole. You can not visibly see the scan lines when seeing 1080i, but certain TV programs are not outputting their show to the resolution you're at, which will cause you to have the green line up at the top of your TV. SOME TVs might let you adjust the settings to rid yourself of the scanline, but most consumer TVs will not let you without the maintenance code to protect your unit from over calibrating and braking your television. Hope this helps.
