Pioneer 9G "buzz" poll (Elite and non-Elite) - Page 48

I can hear the buzz from the seating position 12' away during quiet scenes, but it seems to be mostly reflecting off the back wall.

Now, I know I can treat the back wall and reduce that sound.


But I have the option of returning it and getting the 141FD. I really want the better blacks, but I am concerned that I will end up with this "panel buzz" from the front that may be harder to deal with than the electronic buzz from my samsung. Picture on the sammy is excellent but the black levels at night time are lacking compared to what I expected.


Obviously the 141 has got the better blacks, but do you think I'll be better off with a 141 in the noise department?

I read over 30 pages of the official 141 thread and half of this thread but It's still hard to get a feel for whether most people are getting sound from the front or the back, people don't always specify if they tried putting their ears right against the front panel vs the back to make sure they aren't hearing reflections off the back wall.

FWIW I compared the 141 and Samsung B590 at BB and the 141 was barely audible in the back and not at all in the front while I could hear the samsung pretty clearly.

Thanks for any input.

I'm going to miss the unique styling of the of the clear acrylic trim around the samsung bezel, but I have to say I'm very excited about the Kuro. I hope the Kuro performs as well in daylight conditions as the Samsung.

However, they said they have my set in the store, I wonder if they will let me go into the back tomorrow and unpack it enough to run a white screen so I can make sure I'll be getting a better set out of the box.

I have a Sanus articulating mount, if the 3" size decrease bugs me I guess I'll just move the screen forward a few inches. Nice to know I won't necessarily sacrafice size either.

I definitely do not need speakers. Just recently set up my Pioneer SC-05 AVR and B&W XT2s... Very happy there but the rooms in dire need of acoustic treatments next.


The photo makes the blacks on the sammy look better than they really are. In reality the letterbox is pretty glowy.

I put in a break-in DVD with white screen and heard panel buzzing coming from the front near the bottom, as well as the normal buzzing from the back. I'd say front and back are about equal. This is very disappointing because my Samsung was absolutely silent along the front (although MUCH louder in the back).

I can definitely hear the buzzing from 12' away, and so could my wife and mother-in-law who were both there. Of course both delivery guys conveniently couldn't hear anything. I think its a bit worse than the Samsung was from the seating position.

Either way, I already called BB and they will order another replacement 141FD. The blacks of this TV blow away the Samsung even during the daytime. Can't wait to see the set at night time. I'm also open to the possibility that I won't hear the buzz with normal programming since it seems to drop dramatically when the break-in disk switches to non-white screens.

They knew beforehand that I was replacing the samsung due to buzz and they promised to work with me to find a set that works for me even if it means going through multiple TVs. As somebody else pointed out they still have a comfy profit margin on open-box items, especially since not all customers push for price matching etc.


But I will try powersave2... I was hoping to not have to rely on that but maybe I should just live with it. Unfortunately I'm not at home anymore but I wish I was

My intent isn't to screw BestBuy in any way, but you have to understand that I got this set to replace a Samsung that was buzzing badly, and this one is in some ways worse as far as the white-image test goes because its so directional. The jury is still out when it comes to actual movies etc. But I did still notice the buzz when the break-in DVD displayed a gray-screen. However, with a pure red screen I could hear almost nothing.... maybe indicating it shifted the frequency of the buzz out of my hearing range.

Yes I knew there was a chance the Kuro would buzz but seems less widespread with Kuros; Also, I listening carefully at the store and their Kuro is much quieter with a white screen... I know its easy to say its just a different listening environment.... but their Samsung was just as loud as mine so I think I would've heard the Kuro also since the noise level from MY two sets is similar (as in, from viewing position, both Kuro and Samsung I tried had a very similiar buzz level).

(I'm starting to think that evangelo should have put an audio track on the break-in disc! ) But I have had one for a year, and the other for six months, and we never, ever hear a buzz in normal usage. The 151 requires Power Mode 2 to attain the quiet level I want, the 111 does not (though I still use Power Mode 2 on it just out of preference).

The listening environment thing is frustrating. I honestly could never hear it from any of the panels at Magnolia, no matter how hard I tried. I even had the salesman lower all audio as much as possible, but I suspect the ambient noise was still enough to mask it somehow.

I truly believe you could take virtually any pioneer 9g plasma, play a solid white image with power mode off, listen for buzz, and hear it very easily from 12-15' away. This is an unnatural and unfair test.

You really need to set the panel up in its intended location, play normal content that you'd typically watch at the normal volumes you use, and sit in your expected seating location. Then, try the different power modes. While the buzz on a small number of panels is truly excessive (i know this....i had one once ), the vast majority will be effectively silent under these conditions in power mode 2. Many will be silent, depending on both the panel and your hearing sensitivity, with power mode off as well.

I hear two distinct buzzes. There's a lower frequency buzz thats there even with a black image onscreen, and then theres the higher pitched frequency that changes with screen brightness.

I tried powersave2, and it does make a noticeable difference to the buzz frequency, mostly when the screen is bright. When the screen is not full-bright, powersave2 didn't do that much, it makes the buzz a bit lower-frequency but it is still right there in my head from 12 feet.

I do not live in a quiet house. And I am not striving for a silent theater room. About 15feet away is a 220 gallon reeftank with pumps, powerheads and plumbing, and a refrigerator.

But this buzz gets on my nerves while watching the Dark Knight even on powersave2. Something about it makes me want to 'pop' my ears like you do when scuba diving.
