I wish the humming wasn't there, but I don't foresee it being a problem. I think at least part of it is coming from a fan, because it continues for about 30-60 seconds after the TV is turned off.
Anyone have any recommended settings for the 734 yet? Know if the service menu access is the same as 2007 models?
On both of my sets I heard the humming on scenes where there was little sound and of course muted. If I didn't have the volume up a good amount you could hear it over the sound of the TV.Valnar
my guess is the color wheel due to the sound being a higher pitch sound emulated from say a high rpm.
The service menu's are the same. 2457 service menu and 2470 bulb hours
What I think you will find odd, is all my settings for the color temp low were set at 1024 on both the sets I received. The same could be said for high color temp as well. This is odd because my 732 was spread out between the 3 primary color settings. Either Mitsubishi didnt' take the time to calibrate these sets what so ever or the scales are different from the previous model.
My colors were off on both the sets by a good margin which I can see when I go into my bedroom and watch the same program on my LCD.
