Man, thanks to whoever convinced me to pick up this set. My 500M arrived from Beach Camera yesterday absolutely spotless. Even out of the box, and then even after turning the contrast/brightness way down for break-in, the picture on this thing is just enthralling. Hell of an upgrade over my 2003 Samsung DLP.
I was worried about buzz after reading these forums a lot but my set doesn't seem to have any. There is a noticeable noise (more of a hum than a buzz) if I stick my head behind the set, but I don't exactly plan on doing that a lot.
The only thing that confused me initially is that I kept having to readjust the picture settings since they seemed to keep resetting to the default. Then I realized the set saves different picture settings for not only each input, but each resolution. Man, that is cool. Almost TOO much control, but cool.
Also, switching between inputs doesn't seem to take very long. I set the input delay on my Harmony at 500ms and it seems to work great. Speaking of, is there a list of ideal speed settings for Harmony remotes for this TV anywhere?
Anyway. I'm so excited to finally have my dream TV. Can't wait till it's broken in.
