you should first check all the cables inside the set to make sure they all are seated properly, check some other sources like a dvd player and see if it does it on a dvd, after that it is probably a defective main board

It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.

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.
