Does your 2011 Samsung "D" plasma have brightness pops? - Page 3

post #61 of 2249
I am having the same problem as everyone else. I have a 51D550. I get the the pops and I have all extra settings turned off. Like many have said the picture quality is great but there is some kind of default or contrast adjust that is taking place that is totally unneeded. Samsung really needs to fix this with a firmware update.

There is another problem I am having that is worse than the pops. I don't think the set will display RGB color space properly. If you hook your Xbox or ps3 up and set them to display in there proper modes ( expanded for xbox and rgb full for ps3 ) you should be able to get the best picture quality. But what happens is you will end up with crushed blacks. This is with your HDMI black level set to low in picture options which should give you the correct reference levels for RGB. I believe normal is for Video playback and is greyed out when playing blu rays and other video sources that aren't native RGB. When watching Blu rays and DVD's I get no black crush.

Now I can change my HDMI black level to normal while playing a game but the picture looks all washed out and greyish and lacks the detail of the low setting.

The TV has a great picture but these problems are really killing me. I don't know if I should call Samsung or if they could even help. I've owned my set for about 2 1/2 weeks and don't want to return it for another brand but with these problems and no resolution in sight I might have to.

What firmware does your unit have?

my set has the first released firmware..

feb/11 you go into support-firmware and it should tell you.

i have a theory that the newer firmwares have this issue. because i have absolutely no issues that everyone else in this thread are talking about.

I'm pretty sure the reason why some people see it or don't is based on their program material. A white hockey rink with a dark player moving across it will trigger the effect, a rain forest with all the colors and textures probably wouldn't.

I tried the the above I had a bright background on my TV as a second monitor. When I drag a black window onto the TV I see an obvious Brightness increase. It's not extreme but since I was looking for it, I noticed it easily.

That being said, I don't notice it in my normal viewing experience, so I don't care. That's really all that matters to me.

I set my picture settings to "Standard" and noticed the pops. I usually have it on dynamic and don't see them.

i have never seen it other that this.. but like you .. i was looking for it.

lol...

oh well.

Hello! new to these forums but been a lurker for a long time for getting tips and ideas for calibrating my TV

Yep- I am getting the brightness pops and I am now on my THIRD exchange which will be delivered tomorrow. If it appears again thats it. I'm just going to get my money back and get the Panasonic VT30 series.

I contact samsung online and here is all they said:

Please wait for a Samsung Agent to respond.

Chat Information You are now chatting with 'Jack K'. There will be a brief survey at the end of our chat to share feedback on my performance today.

Chat Information Your Issue ID for this chat is LTK538014044X

Jack K: Hi, thanks for reaching out to Samsung tech support. How can I help you today?

Jeff: hello, i am having a picture issue. I have the plasma model PN59D7000 and during many scenes when watch tv or a blu ray the brightness fluctuates. This is my second replacement and now a third replacement is on the way. Others are seeing the problem too on this forum:

Jeff: ttp://www.avsforum.com/avs-vb/showthread.php?t=1328762

Jack K: Please allow me to go through the inquiry.

Jack K: Does this happen on all inputs (like DVD and Cable box)?

Jeff: Is there a fix for this or a firmware update coming that fixes this?

Jack K: No, there is no firmware update for this issue.

Jeff: yes, all inputs. It is especially noticeable during scenes that pan across from a light color to a dark.

Jack K: Reset the TV and try again.

Jeff: Thanks, but I read another forum that mentions to do that and it still has the same issue. have you heard about this issue before?

Jack K: No, there are no reported issues on this model.

Jeff: It seems a lot of people are seeing the same issue and reporting it but the problem does not seem to be reaching anyone.

Jack K: I will report this issue to concern department.

Jeff: Thank you. Any way to make sure I'm notified that they are looking into it? The Best Buy I go to mentioned they have had 5 already returned. I'm hoping my third exchange will be good.

Jack K: I really apologize for the inconvenience caused to you.

Jack K: Is there anything else that I can assist you with?

Jeff: No problem - you have been helpful on your end so hopefully samsung engineers will look into this. Outside of the contrast and brightness fluctuations it is a great TV.

Ahh man I just got my replacement PS59D550, see below...

Well, I got the new TV, got it up on the wall and.... it's doing the same thing. Contrast / brightness pops.

Totally disheartened now as this TV excelled in every other way.

I now have to move to LG and see how that works out. :-(
post #68 of 2249
I've have the PN59D6500 and have the issues as well.

It was driving me crazy while watching the hockey game last night. I was ready to throw something at the TV I was so upset. This is BS. Where is the quality control here?

I've also noticed when watching a baseball game, I can see the field changing different shades of green.

What a piece of junk. Come on Samsung, get your act together.

Yes, you can say I'm bitter. I mean come on. It's not like plasma is a new technology. You shouldn't have to worry about these kinds of problems at this stage of the game.

Yea and i was watching the football (rugby league here in australia) on an LG and it was going crazy with brightness flucts non stop. Not sure if it was this years model LG as it was at a relatives house and i didnt want to start pointing out its faults. Have also read about it on other years samsungs so it seems to be quite common. Can't say i ever noticed it until getting my D8000 plasma though.

I'd be guessing it may have something to do with getting plasmas a better energy rating in the last few years and also keeping their running tempetature lower.
Not quite sure but it sucks 4 us!
post #71 of 2249
Are brightness pops on Samsungs the equivalent as FBr on Panasonics?

hmmmmm, 96 votes and 70 posts. interesting!
post #73 of 2249
Just a quick bit of info I found. I have a Pn64d8000 this is my first plasma tv and have noticed the brightness pops occasionally. I made a post in the calibration thread about them. What I later found out is that the likely cause of what people are seeing is the normal operation of the ABL circuit, which all plasmas have.

This is an old quote from xrox but still applies:

Quote:
Plasma displays are power on demand devices. If only one pixel is on the power consumption is near zero. If all pixels are on the power consumption is at maximum. To stabalize power consumption they use a ABL circuit (Automatic Brightness Limiter). To understand how the ABL circuit operates you need to learn what APL (Average Picture Level) is. APL refers to the average brightness/gray level of each picture element for a given frame of a signal. A simple way to relate this to the screen is to think of it as the percent of screen at full white. A dark movie will have a low APL. A snowy scene will have a very high APL.

In a Plasma display the ABL circuit adjusts the number of pulses of light according to the APL of the signal. This allows for very high peak brightness at low APL as the power requirements remain low. And at high APL the power requirements are taxed and thus the brightness must be lowered.

If your interested I recommend searching avsforum on the ABL circuit, you'll find a few threads detailing it.

I believe this is considered a feature by the manufacturers not a problem, it saves power and protects the tv from overvoltage. Not saying its great but all plasmas seem to behave this way now to varying degrees.

I guess I'm just wondering if this is what most people are seeing in action. If you have turned of all the dynamic settings and eco/power features it most likely is. Someone with a bit more plasma experience might be able to chime in on this.
post #74 of 2249
^ yes,i have also read on some informed source about the same thing...it's NOT only on samsung d series plasmas,but plasmas in general have this thing...my d550 does have some pops(only upon close monitoring) but imho,...it's negligible & still a Non issue!
post #75 of 2249
59D7000 with no pops so far, had it for 8 days
post #76 of 2249
Okay, I have been complaining about the brightness pops on my new PN59D8000 in several of these forums. I had my 3rd Samsung (contract) repair attempt last night expecting the same outcome..and.. pop's are gone!!!

The problem is they didn't repair anything. The first thing that they did was reset my picture, which really pi$$ed me off since I spent over an hour calibrating it when I first bought it. Then they went into the service menu, but only browsed through it, no changes. After that they asked me to show the problem. I brought up some recordings that I knew were good scenes to exhibit the pops, and there weren't any. Now being an engineer, this really bugs me, as there must be something that changed for the pops to go away, but I can't figure it out. The kicker is, with the reset picture settings the dynamic contrast is set to high (in standard mode).

After they left I went through many settings turning them on and off to see if the pops came back, but I haven't been successful figuring out what the trigger is.

So, if you are at the point I was, ready to throw something at your TV, at least try the following;

Update to the latest software, then reset the picture settings. Check to see if the pops are still there. If so, go into the service menu, but don't change anything, exit and check again. I know, it doesn't make sense; however, what do you have to loose.

One other note, try different resolution outputs from your source (receiver, blue ray, etc) to see if that makes a difference.

I will keep digging to figure out what changed in my set to eliminate the pops.

The problem is they didn't repair anything.

Maybe it IS a hardware problem and you were just lucky? (or rather consistent Because I would've given up after the second set)

sorry if this has been asked how do u get into service menu? and does it void anything? im gain to try what the post 2 above said

The VT30 has Fluctuating Brightness issues, if I'd have known how bad it was I'd have kept my PN64D8000. Something to consider I hope this helps some.

My local technician just got back to me regarding this, as I had a callout for this. He said samsung are aware of it and don't consider it as a problem as it is needed for the brightness levels. And that exchanging won't do nothing, as it is on all current gen plasmas. So same for samsung panasonic.

If what your technician says is true, that Samsung doesn't consider it as a problem this would explain why some of these issues are almost common. I'm starting to think that Samsung is to proud to admit that there is a problem with their products, I own a Samsung product and have loved it since day one (2 years this July), it seems none of these issues will ever get resolved if the manufacture is unwilling to admit that there is a problem here for which there clearly is! Question, does anyone know if these problems ever reared there ugly heads on say the dearly departed Pioneer Kuro plasma line?

While I haven't even mentioned Samsung's banana peeling buzzers until now (whole other thread, another hell for consumer's), it seems as though perhaps Samsung should just stick to what they know best, LCDs and LED based LCDs! I don't want to start a pissing match here, it just crushes me to see soo many issues and problems people are having to deal with, I have read every single post in this thread and many others! It just makes me sick inside to see a manufacture that clearly has the superior technology available yet the quality control is pure crap that renders an almost perfectly functioning panel useless because of fluctuating levels of light output. My 2 cents.

Have you worked in any customer service industry?

People don't usually pop in and say "wow! what a great job!" and people usually don't remember when they have anyway. Most people just remember the negatives.

I don't believe what 90% of the people here say. They want it to seem like the problem sucks the fluid out of thier eyeballs

I have a D8000, I've worked in TV production in the past, amongst other jobs I've held that have been responsible for picture quality, and I can tell you most of the issues people complain about are from using "dynamic" or "Standard" settings, or they have a bad set.

And the numbers of people with bad sets are very low compared to the number of people that you don't hear from having a great time with thier new set (like me).

The only complaint I have about my D8000 is it's heater quality. LOL. I guess I might like it better this coming winter though.

That could very well be what people are seeing. I noticed brightness fluctuations on my C7000 when I had cell lighting too high. Turned it down a few notches and the issue went away. people who have this issue should try turning down things like cell lighting, gamma, brightness, and contrast and check to see if the problem still exists. Most likely you will just need to turn down cell lighting and possibly gamma if it's cranked up too high. Most people set their screens way too bright anyway.

Also, turn dynamic contrast and LCE off.

You sir are in denial.

If you truly don't believe 90% of what people here are saying, why are you even wasting your time reading and posting in this forum.

Yes, we are all dummies, making up problems about are TVs.
post #86 of 2249
I have the pops on my 51 inch D550. I noticed it the first time I turned it on and watched something. All auto settings etc off. In movie mode. Guy who was saying these people having the problem are on dynamic etc should read the thread.

I have the most recent firmware. Samsung BDD6500 player too.

I haven't noticed out with posting blurays. DVD's, Netflix streams and files all exhibit this in various settings. Weirdest thing I have noticed about it was watching some low res files of a television series, then watching 720p files of the same series, same sets and scenery etc, but with greater pops. Could be nothing but it stood out to me.

I'm going to have to agree with hockeynut on this one, are you being serious about that 90%? If so that's a huge waste of time on your part! You know the saying, "a picture is worth 1000 words", if so than for every complaint posted here on AVS, there must be at least ten consumer's out there that don't frequent these and other forums. I seriously doubt that everyone flocks to a forum everytime they have a problem with there newly purchased home theater product, I mean think about that for a moment...! How many millions own home theater gear in the US alone? I can tell you this, if everyone did frequent these forums we would need tens of thousands of moderator's to maintain this forum!

I am having this issue as well. Reset my picture settings (using the Movie Setting). I never noticed this issue when I first got the TV. Seems to have started showing up about a month later.

It happens very randomly. Sometimes I can watch a movie and it won't happen at all. Other times, it happens every 15 minutes.

I hope Samsung is aware of this issue, because the TV is fantastic, but once you start noticing the flickering, it becomes very annoying.
post #89 of 2249
so the 2011 Samsungs also have the brightness fluctuation issue?...I thought it was only a 2011 Panasonic issue...the poll in this thread seems pretty even so far
post #90 of 2249
I will just add that I had my TV for almost 2 months and never noticed the issue, and then in the past month, just started to happen. Don't know if has gotten worse, but it was defintely not a problem at first.

The weird thing is that it is so random. I can watch a bluray and not see it. Then watch TV and have it happen, then watch another 3D bluray (such as Avatar 3D) and it happens every 5 minutes, switch to my Xbox, and not see it at all.

It is weird. Like I said, it is a great TV and I love the picture quality and features, but I hope it is something that can be fixed through software. In fact, I never noticed before the firmware update, so maybe it is related to that.

Has there been any word from Samsung if they even think this is an issue?
