Official Samsung 2011 PNxxD7000 Thread - Page 108

FWIW, mine arrived this morning and is a July 2011 build(stockpile much, amazon?). I have yet to hear any buzzing. I could hear my old panasonic up to about a foot or 2 away from the top edge. On the 64D7000 I can put my ear right to the top of the bezel and I hear nothing. I have yet to view any very bright content though. I'll throw the google tv browser at it tonight and see what happens. that makes my panny buzz like crazy.

Someone was saying that the buzzing improves as the phosphors break in, is this true?

I can hear the buzzing in the sweet spot at 12 feet even with the volume above 20. I have the 59 model I'm wondering if I should even bother with an exchange.

I know none of them will be truly silent, but I wonder if it's worth trying for one that doesn't sound like I'm standing in a power substation.

I have the same dilemma and both October 2011 builds I've had have buzzed enough to be annoying. Does anyone here have a November 2011 build that doesn't buzz? That might give me some hope.

Got mine today. July build date. Buzzing is normal for a plasma. I went ahead and updated to 1014. Very impressed so far. Using cnet's settings. Only thing that is strange black levels on Direct TV and PS3 are lighter than bluray. Weird

I have a PN51D490, built in October 2011, and it's pretty much silent (unless you put your ear up to it). As far as I can tell, it just varies between individual sets, not necessarily from model to model. But it's also possible to exchange a set several times and never get a quiet one.

And trust me...I know what annoying plasma buzz sounds like. I returned a Pioneer Kuro because of its irritatingly loud BUZZ!

I have a 51" October 2011 build. NO ISSUES!! The buzz can only be heard wiht no other noise in house and from 12 inches or less with ear held directly in middle of screen.

I think the issue is from set to set, nothing more seems to narrow down the buzzing issue.

Just got my 59 delivered today from Amazon. Checked the build date and its May 2011, so I immediately checked the upper left corner of the screen, and it had a huge bubble that I was able to press down the majority of. Called Samsung and they're sending a tech out to look at it, hopefully they just replace it. Also it does buzz, I would say no louder than my Motorola cable box though, so it's not that bad. I still have to mess around with the settings, I figure I'll try out cnet's, Larry's etc.

Also, am I just dumb or is their no option when displaying photos on a USB stick to have the sideshow repeat indefinitely. I'm planning on running breakin slides for a while when it's not it use.

I can hear mine from 20 feet back.

it's like a laser beam or some ****.....kinda cool actually lol. Anyway, I asked for a replacement from Amazon. If that doesn't fix it, oh well. I do expect some buzz, but I shouldn't feel like this noise is tunneling into my brain. I can hear it at 30 volume and 15-20 feet back if I reorient the room.

It's like a bad physics problem from college or something

Anyone have a idea why blu ray would look great but Direct TV and PS3 would look too bright?

By chance do you have a Directv HR24-700 receiver?

Larry

hr24-500

Good ol RGB output box with nxp chip.

Yeah, sorry. That's the model I meant.

There is a documented problem with the HR24-500 that causes trouble with current Samsungs (and some other TVs including the KURO.) Change the Black Level setting on the TV to Low. That corrects it.

Don't have a PS3 but try different settings on it. Maybe someone with one will jump in and tell you what to do.

Larry

Looks like setting rgb to full on the PS3 fixes it for the PS3.

I'll just leave the black level setting on normal since I don't want to have to Chang it all the time. Unless there are some good settings that use it on low. Thanks for the help.

You won't need to change the level. Each input remembers what the HDMI Black Level is set at and it will change automatically.

Larry

I would need a separate HDMI cable then. I run everything through my AVR.

Well, I have severe brightness popping and loud buzzing from my brand new 64D7000. It was built in August 2011, FWIW. The TV is going back, but I guess the question is, should I go through the trouble of exchanging the TV for another one to see if I get one without popping and buzzing? What's the success rate on getting a good unit of these TVs, anyways?

I really wonder how Samsung makes money if people are always sending back defective TVs and exchanging them or just returning them. You would think it's in Samsung's best interest to manufacture and sell TVs which don't have obvious defects.

Uh. I think it might have Been updated. Looks a lot better just within this past hour.

That's pretty crazy.

When you go to Photos, hit Tools (I believe).

When you get to the blue control panel at the bottom, hit play. There is a speed option beside it. When you hit play, it will continue until you stop it.

Did we ever figure out what the firmware update 0014 does?

??????

It got rid of my random jumps to screensaver mode during both cable and bluray viewing. Other than than, can't tell you.

Thanks, I don't know what I did the first time, but the second time it looped conitinuously.

Yep, you have "speaker effect". I have the same problem with my set (June 2011 build). Seems like maybe a little luck of the draw to get a quiet set (and helps to have some hearing damage in the high freqs, like many people over 30 tend to have). There is another type of buzz (power supply) that everyone can hear, but this is not usully an issue with these panels. Putting your hand behind your ear or turning your ear to face the screen will make the sound worse.

Try tilting the panel towards your viewing position a bit (Stick a couple of blocks under the back corners of the stand, about 1" or less should do it). Obviously not everyone can do this, depends on how and where you have it mounted. This works for me since my TV is on the stand and isn't mounted very high - sends all that directional buzz/HF crap into my carpet and couch. After warming up for an hour or so, the buzz is greatly reduced like this.

Well, it would have nothing to do with phosphors, but yes, in my experience, the buzz was suddenly reduced after about 300 hours (the last 100 of which I had the TV on non-stop). I then tried removing the tilt I had added to the set and the buzz was just as bad as ever, so I keep it tilted (but a little less than before, about 3/8", which doesn't look as silly as 1").

Anyway, tilting the set has been good enough to let me live with the noise. I have no desire to play TV lottery with exchanges.

Ive not touched the update with a 10ft pole.

Very interesting. This buzz doesn't even seem high pitched to me, it just sounds like electricity buzzing and crackling.

It's pretty incredible how directional it is. In the sweet spot it overpowers the sound of my 360. I truly hope this is a one off defect in terms of its intensity otherwise I can't understand how the design made it through to production.

My breaking point for requesting a return was when I could hear the buzzing over Michael Bay explosions (Transformers 3).

Completely unrelated but this is my first plasma and its eerie how much it looks like a CRT. I kinda feel like I am looking through a soft window as opposed to the sharpness of my LCDs. I like it, but it is taking some adjustment coming from retina searing LED devices. It sorta has a milky, blended look to it that makes the image look better whereas LCD doesn't seem as "blended."

That made probably no sense but I'm not sure how to explain it.

The amount of noise you describe sounds pretty bad, kinda like my set when it's first turned on but worse (no way I could hear it over Transformers action sequences). After an hour or so it's much quieter, except for the noise it beams out at the center position which, to my ears, sounds kinda like a combination of HF "hash" and buzz (depends on what your source is as well).

If this picture wasn't so perfect, I would absolutely not be tolerating noise and floating blacks. I held off on buying a new TV because I never much liked the look of LCD (LED or FL backlit, doesn't matter). Coming from a high end CRT rear projection, I knew I wanted plasma. It really does look like a CRT. Much more natural picture to my eyes, which is what I need because I mostly watch films via bluray.

OK, this may be a totally stupid question, but I'm new to HD tvs and all this built in technology these days.

Anyway, I received my new PN51D700 last Friday...love it btw...anyway, when it came I was still on regular (non-hd) dish network receivers. Hooked it to my dish DVR625 as TV2, via coax cable. Did the setup to scan for digital channels (just to find the channel the dish signal was coming in on) and it surprisingly picked up all the local OTA channels, including the HD channels...clear as a bell. Was very surprised, because I'd assumed i'd need to pick up an antenna to get these, a std rabbit ears never worked except for 1 channel and it was terrible.

Anyway, fast forward to Saturday...dish guy comes to hook me up with HD. Now the TV is hooked up to a DVR722K as TV1 via an HDMI cable. Tried to go back to "TV" and check the local channels and nada...rescanned (for digital channels)...nothing.

Now, we have locals through dish, but here in OK, its not uncommon for dish to go out in a thunderstorm with a tornado approaching, and it would be nice to be able to get them OTA.

Anyway, my assumption was the reason I got the OTA channels on Friday was that it was something built into the TV...pretty sure no antenna associated with the dish or the dvr625...at least they certainly never showed up on my old TVs. What could have changed?? is it that there is nothing now connected to the coax input on the TV and so it shows nothing there?? Was it using the coax that went up into the attic as an antenna of sorts? Any ideas? I sure like the idea of getting the OTA channels and am not opposed to getting an antenna, just don't want to if its not necessary.

Thanks,
JJ
