If you're still in warranty, I would definitely recommend having a service tech come out and inspect your unit before it expires. You can call 800-SAMSUNG or fill out of an Online Service Request here:
I've been very happy with the TV thus far - but I've noticed an occasional flicker in the brightness of the picture. I only recently got a Blu-Ray player and I had assumed that the flicker might have been an up-conversion artifact. That is not the case.
Some folks have been saying that it has something to do with either energy saving settings or burn in reduction settings. Is that possible? I'm checking now as I know there is a problem and I am nearly out of warranty.
I'd appreciate any feedback.
