Some of the fast scenes will have some blur, as that is inherent with a 60Hz LCD panel. The scenes in between some of the games are often 24Hz, and may deal with a 24hz to 60Hz conversion, also causing some blur there as well, particularly with fast motion.
However, the flashlighting issue is something I can't explain. iVersatile, my heart goes out to you because I know you've had a heck of a time with the last exchange. I'd like to say I could step in and make it easy, but I can't guarantee that.
If you'd like, I'll assist to the best of my abilities, but I'll leave that decision up to you.
Give ECR a ring, and post a transaction number, and I'll gladly help as much as I can.
This new set i received as an exchange (LN40B530) about a month ago has two problems... one is i still have Flashlights at the two bottom corners, it originally had them in all four corners but the ones at the top are barely visible now. For the passed month i have tried to live with it because i honestly don't feel like going through what i went through the first time with customer service and the none helping techs.
The second problem is that for the passed month i have noticed that during dark scenes i am having this blur/smearing issue. I first saw it while playing Halo 3 during a dark scene i noticed really bad smearing, after i tried turning Game Mode On to see if it would help but it didn't. I than started playing a few movie/game trailers on my PS3 that had dark scenes in them to see if i saw the same smearing problem and sure enough i did. Any suggestions?
