^^^ I appreciate the feedback Marie.
As far as the whiny noise goes when you power on and off, I think you'd definitely notice it if you have it. it's not super loud, but very high pitch. like the kind that doesnt sound good for your ears. Im sure the technology in plasmas differ from lcds in alot of ways, but I dont believe I've ever heard any TV sound like its charging a laser cannon when you turn it on or off.
Concerning your buzzing issues, I can definitely relate. like you, I can definitely still notice it 8 feet away with only the power on and no input. I watch blu-rays and play games on my ps3, and it can fluctuate pretty wildly depending on the content. Sometimes I can drown it out with the sound, other times when I'm browsing a menu, or during a quiet scene or dialogue in a movie, its just.....annoying, and distracting. What sucks is everything about the TV picture wise is great! Definitely worth the investment, but I'm not sure if:
1. I'm real sensitive to the buzzing,
2. There might be something wrong with the set.
RIght now, I'm kind of leaning towards # 2. I get that plasmas are suppose to "buzz", and I've only had the set for a few days, but I read that the buzzing doesn't ever really go away. Also, my settings are all below 50, and even in custom with the brightness lvl low, I can still hear the set from a distance, especially on a brighter scene. Once the tv is broken in, If I use higher settings Its probably only going to buzz even more.
Even on a black screen with a small, loading white symbol that pulsates (not alot) as a game loads, I can hear the buzz pulsate with it.
I'm sure a person's perception and environment plays a role, but I've read many people on here saying they have sets that don't buzz, or buzz fairly little. I work in electronics and checking out some plasma display models, on bright white scenes, I noticed no buzzing at all. Granted, its hard to judge sound in a department store, but it's an older model (c or s2?) and in torch mode, and I can't hear any buzz. I'm opening tomorrow, so first thing when it's nice and quiet, I'll power it on and give it a good listen.
I'd hate to go through the hassle of exchanging it for another one and getting something worse, but I might take my chances. I should probably post in the GT25 thread and see what the folks there say.
