I was given a faulty Plasma LG by a friend because there was a straight red line down the far left of the screen and they couldn't stand it. I didn't mind it because the tv was brilliant, and free! After a year of daily use, the red line completely disappeared! I'd like to know what it was in the first place and why it vanished after a year. I had to swear to my friend that I didn't get it repaired!
