I've read in the forum regarding the buzzing from the back and top of the 434, i also understood that most of you didn't hear it when you where 2-3 meters away, and not at all with normal volume on the tv. I got mine yesterday, and the buzzing can be heard 3 meters away when no sound is on, when watching at night with not as high volume level as normal i can clearly hear the buzzing also which is very annoying. The media reciever fan is not as loud as the buzzing. To me it sounds like mine is worse than the buzzing on the screens that some people here has recieved, or perhaps i'm just sensitive for that kind of sound. The problem with the sound is also as you all now is that it changes with blacks/or white so it's hard to get used to it... Is my screen broken or am i just as i write above to sensitive? Should you really hear the buzzing 3 or even 4 meters away or when listening to normal/low levels at night?? Any thoughts?? Can any setting for picture or sound change the sound to the better or worse??
