Official Samsung 2011 PNxxD7000 Thread - Page 136

Calculus,

Plasma (and LCD) panels do not interact with the magnetic fields emanating from speakers. That is a phenomena associated with the high energy electron beam in a CRT. Flat panels operate using a totally different technology which is not affected by magnets.

From what I can gather from the photo of your screen is a slight case of non-uniformity -- and a screen in need of a calibration.

WRT the non-uniformity issue: Only a panel replacement will cure this but it has been my experience that there is more uniformity problems with the later production of D7000 screens than has been discussed. My current screen has a similar problem such as you have but a bit less pronounced.

For the calibration problem: Since I assume that you do not have the required equipment to perform one, try reducing both the G-off and the G-gain settings. Be gentle though. First try changing G-off a click or two. If that doesn't get rid of the greenish cast, work with the G-gain. (If you previously had made changes to these controls, record the values before changing them. In fact, without equipment, I suggest setting them all back to the default 25 and starting with a clean slate.)

The offsets will effect the near blacks and the gains the mid and near whites. From your photo, it seems that the blacks at the top of the hills are green but this may be the result that the cinematographer desired. So you'll have to use a number of sources to check.

Larry

Larry,

You are amazing, it definitely did help a lot after I turned G-Gain to 0, was using Chad B's Calibration, I know I shouldn't just copy the numbers, lol, lol)!!! Either way, a technician should be give us a call next week since this set is still under warranty. Hopefully they can get rid of the problem somehow along with the slight buzzing (read many stories about that as well). Either way, thanks so much, love your expertise and all of helpful comments in this forum (Die Hard Sox fan as well here, maybe I got the wrong person, thought I read it somewhere - tough season and not very likeable team for attending Pesky's Funeral, that's for another time, thanks again).

Lin

Lin,

If I had known that you copied settings, I would have suggested a different approach. That would have been first to reset the Movie mode settings to their default values and go from there.

Reducing ggain as much as you did is more than I would have suggested. But if it works and you like the results, it's fine.


Oh,yes. I don't think that I ever mentioned my long time affair with the Red Sox, but I am, indeed, a fanatical fan.

Enjoy,
Larry

I just bought this tv a couple a week ago, and even though it's a bit late, I have a few thought's and questions.

I paid 9k dk(1,5k dollars). We're a very overtaxed country though, so I think it's a pretty good deal, even though i'm considering swapping for an ST50. The 55 version cost's 14k though, and I can't really see myself paying +50% extra for a decrease in size, even though the Panny likely has very low buzzing.

Bought it through an online retailer(proshop.dk), kind of a challenge getting it up to the third floor. Does 7-10 metres higher altitude affect the tv?

Apart from some directional buzzing, I think the tv is fantastic. DLNA works like a charm, and plays anything I throw at it including fairly large HD movies all over wifi + the picture is like a window into another world. Haven't tried 3d yet, even though it came with a pack of two 3d glasses. Looking forward to it though

Regarding the buzzing, my acoustics likely doesn't help with hardwood floors. I've read there is various options to decrease it, either by wallmounting it or setting up some acoustic tiles?

It's an october 11' build, will I be better of swapping it, trying to get a newer build?

I'm intrigued as I just bought mine a little more than a week ago. Is it a significant decrease? What build is your model?

Regarding led, I have to agree. Ever since i've got this, all lcd's looks like a game of cs from a couple of years ago The picture is awesome though, like looking into a window to another world

Just submitted a service request for my beloved 64D7000. A couple of days ago I noticed a flashing red pixel a couple of inches down and a dozen inches from the right side. On closer inspection it turns out that it 'wanders' i.e. it's a handful of pixels in more or less a straight line that take turns flashing red. It looks like there has to be some light output at the same height for them to appear as they don't show up in black (letterbox) bars. It's very annoying and I noticed it while watching regular full screen content.

I'm 11 months into my 12 month warranty period and it'll be interesting to see what the service tech says when he comes out next week.

So I got the panel on my 64D7000 replaced today. When I check display time in the service menu it's consistent with what I had on the panel that was just replaced (as far as I remember). Is that correct? A panel replacement doesn't reset the hours? Or did I get a refurbished panel that just happens to have approx. the same uptime as my old one?

You check the hours on the panel by pressing mute>7>3>7>enter. The time is shown in the MRT item. Exit by turning off the TV.

Larry

Thanks Larry, I thought I'd seen mention of another way to check. MRT is at 0 and when I run slides the image is indeed very clean and free of the hints of IR that I had on the old one. It was very faint and only visible on slides so no real issue but definitely evidence of my 1000 hours of use. This new panel is squeaky clean.

On the old one I had one dead pixel close to the center of the screen. It didn't bother me but I have to admit I'm pleased that the new panel doesn't have any :-)

Not sure if everyone knows about it already... The HBO app in our PN59D7000 works perfectly fine now :-)!!!

I just pulled the trigger on a 64d7000, i've been doing allot research and couldn't pass up the deal I got. It will be replacing my Sammy 52a650 as my main TV. This is my first plasma and unsure whether or not to break it in with slides. read that there is no need and just to avoid letterbox and still images for the first 100hrs or so. Let me know if i'm wrong here. Did any of the updates address the popping issues and anything else that would be beneficial that i may have missed would be greatly appreciated. thnx

Follow the instructions in the "D series Fbr Fix" thread if you notice the pops (I'd be surprised if you didn't) and hope that yours don't return later like they did for some of us.

Congrats on your new TV!

Ive never been a believer of extended warranties but from what ive read this tv kinda scares me. Am i being paranoid or should i grab an extended warranty. Seems like good odds that i get a bad set ... Is it a 50/50 shot here...??

If you have the full Samsung warranty I would think you should be okay.

I grabbed Best Buy's extended warranty and I am thinking about returning it for a credit because I don't think it will be that useful with this Fbr issue - I'm 90% sure they'll tell me it's not a big enough issue to warrant repair/exchange.

Samsung just replaced my panel on Monday so in 5-6 months I am hoping that I am still pop free.

Yeah, I would agree with that. The most common problems with the D series seem to occur well within the warranty period (of course we only have a little over a year of experience with them, so take that with a grain of salt). The more "minor" problems will likely require a lot of luck to solve through any warranty, Samsung or extended. The best advice is to find a good return policy or consider another make or model if you find the risk unbearable.

Good advice guys thanks. I bought from Crutchfield and they have a great return policy 60 days no questions. I'll keep my fingers crossed in the meantime. Setting the TV up tomorrow.. Thanks again for the advice much appreciated

Well, I guess I got a buzzer and the bezel or metal trim on the top right corner keeps popping loose. Build date was Jan 12. Can't decide what to do. Love the picture but the buzzing is annoying and it's directly in front of the tv roughly 11ft. The buzzing is coming from the panel on the bottom just above the bezel and on top just inside the bezel both pretty much in the middle of the set... Tried the ferrite cores but no better.. Could a power conditioner help or am I stuck. I have read where some claim that the buzzing gets better around 200hrs is this true or could it get worse...!!

No. Buzzing will not get better (but if it's not too bad you might get used to it, I know I have). Ferrites prevent the TV from radiating RF interference so they will not have any effect on audible noise. Power conditioners will have no effect either (I use a high end model from Torus).

The noise you hear is part of how plasma TVs work. Seems if you're lucky you can get a quiet one, but they usually make some audible noise (especially if your hearing is sensitive to it). The bezel is covered under warranty.

I read in a a thread that adjusting the rheostats can reduce or eliminate the buzz. Has anyone verified this or can it even be done. This is the link
http://www.avsforum.com/t/1322413/official-samsung-2011-pnxxd8000-thread-no-price-talk/3420#post_21102377

On some models you can adjust the panel drive voltages with rheostats but this has zero effect on buzz. What you are hearing is caused by pressure modulation in the plasma gas and can't be adjusted.

Ok.. Thank for the info...the pic on the tv is gorgeous ill just deal with the buzzing.. Thnx for the replies

BTW, in my case I was able to minimize the amount of buzzing I hear by tilting the TV slightly toward the seating position. More of the noise seems to focus downwards on my set, so angling it keeps most of the sound below by head. However, it's still pretty bad when first turned on. I still probably wouldn't be able to tolerate it except for the fact that, once the TV warms up, the noise is barely noticable.

My 51" D7000 doesn't have a buzzing problem, but the darn thing makes lots of fairly loud snap/crackle/pop noises for about 30 minutes after it's turned either on or off as components heat up or cool down. There are a variety of noises... some of which make you swear that the glass in the panel just cracked.

Oh yes, the expansion crackels or whatever they are. I don't have those at all. Seems your problem is not as commonly reported as this high pitched "buzzing", but I've seen quite a few comments about it. I have a 59".

That thermal noise is unusual. I'd submit a repair claim with Samsung. The TV may need just a reseating of the panel/chassis.

Larry

Yeah, but... the TV has been so darn good otherwise (great picture/color, no pops, no buzz) that I don't want anybody to touch a thing!

Hi guys,

Please help.

I had an LED tv before and when using the warm setting, the color was very much red, however on my current plasma, warm setting if anything gives a more greenish look. Is that normal?

I thought cool = blue and warm = red.

Is the greenish abnormal, or does the warm color vary from tv to tv?

thanks

The warm to cool transition on these sets simply changes the amount of blue in the grayscale, but things can start to look reddish in warm2, especially to the untrained eye. Warm generally shouldn't look greenish, but I suppose it's possible (especially if repairs have been made to the TV). Unfortunately, this is a difficult thing to address without a calibration. DIY with a meter can still be done for $200 or so I think, but requires some time investment. Beyond that, there's not much you can do - however, you should at least do a proper calibration by eye with a test disc in movie mode. Try AVS HD 709 or buy a disc. Samsung provides a "blue only" mode that is very accurate for setting color and tint, but this could still fall short of solving your problem.

Well it doensn't look horrible.

I was just asking, because my samsung LED's I had before when going from cool to warm2 you can definitely see it looked "warmer" by having a more reddish tint. However, on my plasma it certainly looks warmer, but it seems to give a greenish tint as well.

It looks fine I suppose, not an expert at calibrating or anything. Hard to explain what I'm seeing.

And my tv was not used, was new.

thanks

That's because the offset is wrong. I adjusted my offset by looking at a blue ray with two people; a black persons face and a white persons face. Then I adjusted the offset so they looked like the color they would look like in real life.
At default the offset is set to 25 for red, green, blue, but green should be lower than red and blue, and red and blue should be about the same value.

The blu ray I used was "Ninja Assassin", when the detective lady was talking to the widow about the widows husband. I just freezed the frame and fiddled with the offset so it looked about right to me.
