Wait, is this my first post? Hi everyone!

Would some kind of sound insulation or absorber help? My TV seems to buzz louder when it's turned on initially, but the noise seems to be less loud after the TV warms up. Or is this just all in my head?

I can report that i hear NO buzz from the front and barely a faint from the back. I hope this stays true as i log in more hours on the panel. I wanted to thank you all for all your input, as I've learned a great deal about plasmas, and especially about this wonderful set.

I do have one question for which i was unable to find an answer in this thread. I don't plan on running D-nice break-in settings. I plan on watching regular (full screen) programming (mostly movies in pure mode) for a least a couple of hundred hours. My question is this, should i change the picture settings for the first few hundred hours, or should i stick with the settings out the box?

Thank you all in advance for your assistance/guidance.

Just be aware that the pixels change the most during the first few hundred hours, so you may find yourself tweaking the settings a little over the first couple months to adapt to these changes.

BTW......congrats on your brand new toy!

Flat Panel Display Motor
The screen of the flat panel display is composed of extremely fine pixels that emit light according to received video signals. This principle may cause you to hear a slight buzz or electrical hum coming from the panel. This is a normal sound for the flat panel display and does not indicate a failing unit.

A Google search of "Flat Panel Display Motor" had zero hits...

This is sort of what I hear when the tv is on and its completely silent in my house.

It can't be heard during normal viewing, and only during the quietest movies scenes if I actively listen for it. However, it can be heard well if everything is silent and nothing is playing.

Is this pretty much classic panel buzz?

To me, truly excessive buzz is that which you hear from your normal viewing distance, watching normal content at normal listening volumes. Using Energy Mode 2 often reduces that buzz to an effectively silent level, and owners of those panels have to decide for themselves whether that's an acceptable solution. A very small proportion (as far as I can tell, based on owners' comments in this thread) are not even quiet enough in Energy Mode 2. I consider those panels defective.

BTW, I also have a Fujitsu 50" in my other house and I can hear its panel buzz more than a foot away.

I'm pretty sure it is indeed panel buzz, I just want to make sure so I can get over the issue, and consider it something that comes along with the technology.

Ask Atkinson to explain directed or focused ultrasonic sound when demodulated is heard as a buzz in the optimal seating position (which is not 4" from the screen).

That said, panel buzz has a very specific character:

• It's almost always very directional, as if the glass surface were a parabolic dish focused on a particular spot in front of the TV (usually the viewing sweet spot ). So it's usually drastically less noticeable if you simply move up, down, or side-to-side. (This is why tilting the panel slightly away from the normal viewing position is one of the known "solutions.")

• Also, you can often "follow" panel buzz to a specific spot on the panel, as if it emanates from a certain quadrant of the glass. If you try to move around to the side or hear it from the back, you won't. (Electronics noise, like power supply hum, is what you hear behind the panel.)

• And finally, panel buzz is usually greatly reduced in Energy Mode 2. This is sometimes true with various electronics noises in the back, according to a few owners, but it's a pretty consistent result with panel buzz.

Don't know what to make of this...

I think its just a matter of getting used to the noise, in a few weeks, I'll probably tune it out anyways. As I've mentioned before I only hear it if I actively try to hear it.
