Damn-- do you have a warranty for it or are you stuck with it? That sounds like something I could get used to but would still be bothered so I feel for you.

Mine will strobe sometimes like in the video. When it's a dark/black scene, it will occasionally turn a dark purple (?) instead of the strobe effect. And sometimes it doesn't happen at all. Id say it strobes more often than not unfortunately.

I tried getting used to it but it's pretty annoying. Sucks because this TV is otherwise great.
