from what your suggesting this does appear to be an manufacturing defect you should call 800-Samsung for service.
I have a 40in 650 that has a blue vertical pixel line from top to bottom on left center of screen. A few months after i bought it the line appeared but disappeared. the day after the same thing happened except the line came on and off while tv on. the third day it stayed put and has not gone away at all. I read that it was something called "delamination" and that i would need to get the whole lcd panel replaced. Its still under the manufacturers warranty. I wanted to do some research about this first. does someone know which tv repair shop samsung refers people to in Austin,TX? Any others with same problem with this tv series? any info would be helpful. thanx
