Hm, good news is I got Best Buy to match that extra 10% off on CC's website, so I'm down to $1535 for the 61" before taxes. They even took off a little extra for some reason.
Anyway, the sensor in the middle was an issue on my older Sammie DLP. When I got this one I put the speaker on the shelf below, but noticed 2 little leds on the right side of the tv that light up when I use the remote, so I thought great, I can put speaker on the shelf again. I now have two receivers to test in home, so I put the second where the speaker was and put the center back on the shelf in front of the tv. The speaker is too tall and blocks part of the screen though, just under 1/2" probably is blocked. And it appears the sensor is still in the middle because I had issues getting the remote to work again.
However, I have found if I point the remote straight at the speaker from my seating position, it works. I have about 3/8" of a glass shelf below the speaker, maybe it's getting through that some how, I am not sure yet. Trying it from the left of the seating position it works more reliably, but still cannot see the center power button. I really can't tell where exactly the sensor is, but this tv seems more fogiving than my other one.
My center is 7 1/4" high for reference.
