There seems to be no solution to the problem yet although it seems that it could be fixed by firmware update.
What bothers me even more is the "transformator" buzzing sound you describe. Turning on ESM2 makes it almost disappear but I haven't made up my mind what I should do: accept the buzzing or live with a potentially lower brightness/PQ. I coulnd't spot a difference between Pure and ESM2.. at least not with a quick glance.
All in all, I find these defects very annoying and I'm puzzled what to do.. I got until next thursday to make up my mind. Return the set and get my money back or somehow live with these annoying sounds.
I guess the fan noise can be fixed while the buzz can not because it's "by design".
Hi Korn and thanks for the reply!
Nice to know that I'm not "alone" ;-)
Thanks to the Google translate service I was able to somewhat get the German thread translated into a semi-understandable language.... And it seems like you and me are not the only ones with this problem! I don't understand why this issue has not been adressed in the quite long thread about buzz from 9g Kuros here at AVSforum...
Anyway I will try to upgrade the firmware when I get home today as I don't think I have the newest version on my tv. My dreams of this fixing my problems are VERY low, but I guess it won't hurt to try.
Even though there is quite a lot of posts on different forums from people with buzzing issues on their 9G Kuros, I can't find a lot of posts from people who in fact have contacted Pioneer's "PDP+" service/warranty and seen some good results from doing that....
I will continue to test and check my tv during the weekend and if I'm not satisfied with the buzz from the panel and the coming/going noise from the mediabox, I will call my Pioneer (Norway) and ask them to come and check it out...
Regarding using the powersave mode 1 or 2, my experience so far is that when wathcing a blu-ray movie (from PS3) this doesn't affect the picture/subtitles too much and YES it reduces the buzz from the panel a bit (but NOT quite to a satisfying level). But when watching SD material (cable-TV), the powersave mode DOES affect the picture and I can clearly see the subtitles adjusting the brightness level when scenes are changing from dark to light and vice versa.... This is something I don't like and therefore I don't want to use this powersaving mode when watching SD stuff, but then again the buzzing noise becomes too annoying.... :-(
I'm crossing my fingers and hoping that Pioneer will take my problem seriously if and when I'll call them, because I don't have an option to return it to the shop I bought it from!
