I have a 5 month old Samsung panel, model 712N, and this morning when I woke it up, it looked normal for 3 seconds, and poof, white screen; next, there were very, very faint, thin, yellow, pink, green, blue lines that ran vertically down the screen. I though, hmm... I powered it off, then back on. Fixed -- for another 3 seconds. Reboot, same thing. Checked connections, same thing. I thought it mighta been my vid card, so I hooked up the monitor to my laptop. Nope. It is dead! Now, here's the kicker -- I visited Samsung's site to see about warranty stuff. They'll send me another unit via 2nd day mail, but it is a refurbished one. I didn't buy a refurbished monitor! I bought a new one and a screwed up one at that! Why should I ultimately have to spend $450 on a refurbished monitor? ARGH! Oh well, had to vent. I also wanted to check to see if anyone else had seen a problem similar to this.
