Any idea what current firmware addresses?
1014

Nothing online about it.

Unfortunately, the ferrite cores do not and cannot address mechanical noise emitted by the panel or power supply (on my set these are seperate and unique sounds, btw), they are included to minimize RFI (plasmas being a major offendor, but probably not an issue for you unless you operate a ham radio). There is no harm in using them so long as they are placed at one or both ENDS of the power cord. You do not need to use electrical tape, simply loop the cord once through the choke and lock in place (a very common way to attach them).

Even though I knew this, I went ahead and tried a number of things related to the incoming power. A single core at the set and cores at both ends, no obvious effect. A very expensive (but cheap used on agon with a little luck) Torus BX5 iso transformer/surge arrestor, no effect. I have left the Torus in service because the picture is a bit cleaner and it provides significant additional rejection of RFI as well as high quality surge protection. I have also left the ferrites attached at both ends of the cord for now.

I noticed the update last night. I hope info comes out what it addressed.

Sorry to have possibly contributed to your frustration with my verbose and perhaps at times arrogant posts. I do have a strong background in science and engineering, so can't help but pick things apart to no end. Your point to those who do not own a set is well taken.

But the reality is that Samsung has some major issues that they don't seem to be owning up to, most importantly the floating blacks. I watched many a BD with very little of note, but have also seen several extremely obnoxious instances. Maybe they're worse on some sets, I have no idea.

I feel we have a responsibility to the rest of the community to report on these defects so people will at least make sure they have a good return policy when purchasing. I'll be more than happy to praise the picture quality, but that's been covered quite well here and on the review sites (which, BTW, IMO, are far from qualifying as "peer reviewed" in the traditional, scientific sense). Also remember that, like in politics, a vocal minority might be helpful in getting some attention from Samsung. Maybe they can come up with a FW fix, or maybe they'll come up with a repair to at least minimize the FB (like Panasonic).

BTW, I should also mention that the directional HF noise coming from my panel has recently taken a turn for the better! Probably took 300 hours or so of break-in, but it seems better. I'll report back in another week if the trend continues.

I can't verify either way, but I suppose I'm around 450 hours with my TV in about 6 weeks now (I run a hell of a lot of slides lol), and I don't think mine has changed. I won't mind the "normal buzz" that the plasma has if I can get the fix from the bug-zapping-like noise. Again, the only time this is even really any sort of annoyance for me is during movies (it gets significantly louder the instant I get the 24 Hz display, even though it's not the 24 Hz option that's causing it). During games, it's fine and not a nuisance. It could be because games always seem to have sound and your focus isn't completely on said sound anyway, but either way, watching Blu-rays, I'm seeking another solution. I've angled my TV even more downwards, which should help some, but I think if I angle it any more, it will become a viewing problem.

As for FBr, I think many of us would be more forgiving if the television didn't literally pop into different brightnesses. If it just adjusted very slowly and progressively and transitioned into different brightnesses, we might not even notice it if that happened. As it stands, because it pops from brighter to darker, it's just so apparent that it becomes annoying as people have described. The most recent firmware (1014) has not addressed this issue.

This TV is awesome, sans these two issues. If these two were fixed, I don't know how anybody could ever complain about this set. Yes, it would be cool to be able to get Kuro blacks, but I don't think beggars can be choosers here.

Not exactly. Under any stock setting or any manual adjustment the pops are still there. If you turn up brightness or contrast they can be seen easier but the frequency of the pops remain the same. It is clearly an issue and appears to have to do with the energy saving reduction they put on this tv from compared to last years model.

Yeah, it's really hard to figure out this panel noise. Admittedly, it seems to be mostly high frequencies and many people will likely not hear or not be bothered by it for various reasons. But for those who (1) have it and (2) can hear it, there are times when it can be extremely annoying. Far more annoying than other common household items that make noise. I have experienced some variability in the sound over the 300 hours, but it's been pretty consistent. I was able to get it down to an acceptable level by tilting the panel towards the couch and making sure I sat prefectly upright. I was "breaking-in" my set with live tv (zoomed), for maybe 10 hours a day. Then when we left for Thanksgiving weekend, the tv didn't get turned off - so after ~72 hours continuous (on top of over 200 hours, 10 hours at a time) my noise level seems significantly reduced (not eliminated). We'll see if it holds.

Agreed, if they could ramp the brightness slowly it would be acceptable.

This TV is awesome - I spent Thanksgiving watching a brand new 60" Panny GT30 and was very unimpressed (but that set was dead silent!). I even spent time going through D-Nice's and other's recommended settings - it looked better, but the image simply didn't have anywhere near the "pop" of my Samsung. If I could do it over, not sure which way I would go to be honest.

Oh, and BTW...

THE OTA TUNER IN THE SAMSUNG D7000 IS EXCELLENT. Many people probably don't use it, or don't appreciate it, but with a decent antenna I have all of NYC's broadcasts at my disposal. If you've never seen the difference between HD programming from an OTA (over the air) source versus cable, and live near some good stations, do yourself a favor and get an antenna. It makes DirecTV look like TOTAL CRAP.

Knowing a bit about OTA tuners, and coming from an older generation Samsung STB (which was and still is highly regarded) I can tell you that one thing Samsung does right is tuners. You will not find a better one in any of the comparable plasmas out there.

Sorry the cores didn't help. Like I said, experts could speak more on them.

For both you and muffin, I really think you should call Samsung and have them send out a tech. I know last year when Pannys had a similar problem it was usually a bad power board or whatever when the buzz was very loud.

High elevation like being in Colorado or other spots also caused excess buzz.

I have no problem with pointing out the issues to an extent. It just got so out of hand that I had to speak up.

And, Samsung or any other manufacturer couldn't care less about these posts. What they do care about are calls and service visits, because in both instances they have to pay people to give you some attention.

Floating Blacks are a "feature" of all current plasmas. Said that a few pages back. It's the C.A.T.S setting that you can't totally turn off due to energy ratings. They can fix it if enough let them know DIRECTLY through an update.

By peer review, I did not mean scientifically, but literally. A reviewers "peers" are other reviewers. Credibility leads to readers, so I did not flub on that point either. I am no fanboy of Samsung. I've never owned a Samsung anything and don't like the company much. Just giving credit where due.

If we were talking Apple, then I can be called a fanboy. :-)

I've already read up on the topic, so I know what the experts say about ferrite chokes, which is why I corrected you. Suggesting that they would address mechanical noise is simply spreading misinformation. Even Samsung states they are included to "reduce interference".


And I submit to you that the only thing which may have gotten a little out of hand was people posting who have no direct experience with this set.


Let's agree to disagree then.


Agreed. Precisely what I have been encouraging in the relevant thread.


The source of the problem is well known and you're not the first to point it out here. Unfortunately, the implementation is severely flawed. Energy standards do not require this function to be locked in as it has been. At the very least, there should be a reduced brightness setting that will eliminate the pops. Janos offers some good insight in this thread.


I simply expressed my opinion that this is not a term to be used casually. Suggesting that the few review sites out there (some of which are highly questionable to begin with, IMO) can be considered "peer reviewed" is misleading. At best it's casual, but what effect is it having?

Most importantly:

How many review sites actually use random samples? For example, cnet gets their review set direct from Samsung.

How many review sites actually spend the time required to fully experience the set? I mean, really LIVE with it? None.

I ordered a pn64d7000 thru sears after days of being an info vulture here on the site and I finally received it after two weeks of anxiously waiting. After opening the box I discover the the screen is cracked all over and the back side of the tv is dented deeply in three different spots. To say the least I was and am FURiOUS! I would recommend that anyone looking to buy from sears beware! They said that I must reship the set and wait for them to receive and process the refund then wait for the funds to hit my card before they can ship another with regular ground shipping thru the same demar logistics company. Is there something I might ask to make this situation more in my favor? Thanks

The box appeared to have no physical damage. Also the shipping company refused to wait for me to check the tv and plug it in before signing saying that it is their policy to bring it to the door and that's it.

That's pretty ridiculous.

That sucks.

Im a big fan of Amazon. Their policy is to have the deliverers plug in to check to see if it's operational. Also, I tipped the guys and they set up the entire tv without a problem. I had to return one and they helped take it apart and pack it.

That was great. I wasn't able to leave work to receive the tv or I would have made them wait while I checked it over. My 95lb wife was just happy that they brought it upstairs. I also have been eyeing amazons price. If it wasn't for me getting my 64 with tax and shipping for about 2100 I would go somewhere else with my business.

That really sucks! I bought my TV from Vanns ( the 59 inch ), your deal from Sears is insane for the 64".

http://www.vanns.com/shop/servlet/it...res/463402957/

This is the first time that I have been prompted that one is available without going through the menu to check.

My recollection is that early problems with automatic firmware upgrades caused the feature to be disabled on fear of bricking the TV while trying to upgrade. When I have previously learned of a new firmware, I have had to download it to a thumb drive and insert the drive into a usb port of the TV.

I take it that a prior firmware revision allowe updating to occur automaticlly, becuase last night I was prompted to allow it to happen or cancel, I pressed OK, and this morning I was prompted that the download was complete and did I wish to install the upgrade. I pressed OK, the install started, and the TV cycled through off and on.

I did not have time to verify versions this morning, but all appears to be fine.

Well the way I got the deal was because a while back when the hp touchpads went on the fire sale I ordered one from sears and never got it. So by the time the investigation was over and they determined that there was a shipping problem they where. I longer in stock so they offered 20% off my next purchase. Now that I just got off the phone with them they are going to send me another one with an additional 10% off!! The total cost will be 1866.47!!! I guess everything happens for a reason.

I forgot to mention that last night I plugged the tv up and it made a buzz so loud that I literally thought the thing was going to explode. I'm not sure if this was a result of the damage that was done or if this is the "buzz" everyone on this forum speaks about. But I hope that it wasn't normal.

Bought my 59" back last March and paid $2300 w/ 3D kit. I think the 64" was close to $3,300 back then. The TV was so new, that there were no reviews or anything, and I took the chance it would be better than the previous year model ( which was reviewed pretty well ). Turns out that I guessed well.

Glad to hear that u are enjoying it. I hope to be doing the same soon. My three pairs of glasses and Harry potter 3d are getting lonely.

I love the TV. I haven't had any of the problems with the TV that some have, and the TV is awesome looking.

Wow Looney what happened to you is just insane. But yes, that is a good price. I really hope Sears can get their act together and get the replacement to you before Christmas day. I also pray that your next set is issue free and that you fully enjoy the set.

I hope Sears ships it to you for free if there was a charge the first time.

Thanks. My wife and kids were in the living room watching me and my neighbor unbox the beast. I gotta say I haven't been that embarrassed in a long time. My four year old daughter even had on the 3d glasses! Lol. She didn't understand why we couldn't watch it.

I'm also gonna miss a lot of texans football on it

And it's gonna be in my living room looking at me til monday since the delivery people aren't picking it up til then.

Have a PS3 and PN59D7000 tv that both have the latest firmware but when I go to play Thor 3D a blue screens comes up and says in order to play this disc it requires a capable HDTV and Bluray player, which I have... I can play 3D from the sat dish like ESPN3D... confused!

I believe that there is a setting on the ps3 that you need to search for. I'm read on this forum a few pages back about it.
