I have a HD-61FN97. I read posts suggesting an Omnimount mount for a center-channel speaker so I got one, placing it on top of the middle of the screen (I have a Paradigm CC-370 center ~ 25 lbs). After around 90 days, I have noticed the center of the screen sagging by about 1/4 inch. I removed the Omnimount/center channel, putting the speaker on a shelf below the TV. I manually stretched the screen's center vertically some. Now it's off by less than 1/8 of an inch. "Lesson Learned" about the strength of the screen's framework.
