How I discovered the issue:
I was watching Star Trek (2009) blu-ray and noticed that the black bars looked GREY. I was like WTF! So I tried changing the settings, turning the television on and off. And no avail, the overall PQ was terrible. I got up close to the television and looked at the black bars playing on the movie. They had green and blue pixels dancing in the black. I tried to take video but it didn't turn out.

I am starting to lose faith in this television due to this issue, the fact my set buzzes and I am also experiencing some SERIOUS line bleed as well (I spoke to soon regarding this topic earlier.)

Can someone else please try to reproduce this issue? I want to find out if I am the only one?


Thanks!

You are 100% correct... and yes ALL 58-63C8000 sets have it! (But it's so fine, most owners wouldn't ever notice it, like fine spider scratches on a new car paint job!) As a matter of fact, Samsung had a rep at my local BB last week trying to explain to five geeks (I guess I was one of them) who were complaining about this issue while pointing to both of their display sets that plainly had the problem.

There was some discussion about "cross-talk" in poorly made (read as cheap) HDMI cables. So we all helped to switch out the the HDMI with another MonsterC HDMI.... unfortunately it did nothing to improve the problem. Then his attention went to the player BB had feeding all these sets (it was an older Samsung model) then to the switch box etc etc.

Installing a brand new Panny BR player directly to the set without a splitter of any kind did improve the problem by 50%. That did help a little but not completely.

So you are NOT alone!

To be continued.

Are you using optical or HDMI for your audio? I'm using optical.

Well, it's perfect this morning - 5/31 8am Pacific time - on all channels that I checked. It was also perfect last night on History International HD.
I can't figure out what/when causes it to go out of sync.
Frustrating

This issue washes out the entire picture and affects overall picture quality. I hope this is not an issue with ALL plasmas.

The reason why I noticed it was because the black bars on the movie I was watching (Star Trek (2009)) were GREY, not black at all. The picture was completely washed out. I had to adjust my brightness to a setting that took me out of a correct calibration.

What did the Samsung rep say about the issue? Did he say Samsung was going to fix the issue?

And, just a few hours later, History International HD is out of sync. More and more, I'm convinced this is a Dish Network problem

Bought my 58" C8000 on Saturday and finally got to hook it up today. Initial thoughts:

* Picture quality is great right out of the box. Had to turn off the Motion Dejudder thing ("motion flow" type feature) because everything looked overproduced and too smooth. Color is great. Glare is apparent but not the worst I've seen.

Buzzing: this TV buzzes! When the volume is less than 6 or so, you can hear it. (We were sitting about 12-15 feet away). When the scene changes, or a show goes to commercial and the sound cuts out, you hear it buzzing. It sounds like a mini-fridge running. I'm going to call Geek Squad and have them come out to witness it.

I'll post more when I get into it more. Hopefully later tonight I will hook up the xbox360 and see how it goes. So far though, besides the buzzing, I think this is a great set!

Go into the screen burn protection and adjust the side grey to dark and let me know if it fixes the issue.

That adjustment is for the L/R "side" bars of 4x3 content, and not for the top/bottom bars of letterbox movies.

Very weird. why am i not seeing any of that on my set. black bars are always jet black. even standing right in front of the screen. Not sure why only some people are experiencing this. Maybe there is some defective sets not sure. I am hoping I dont ever see it since I am very happy with this set so far.

My c8000 has the same exact issue.. BUZZZZZZ.... you cant hear it if you stand up, you cant hear it if you walk to the side. But if your head is at the horizontal midpoint of the tv, you hear it from 15 feet away when the vol goes low. I had BB bring another out here and it does it too. I am so bummed as this set is awesome in every other way. PQ is great. I cant live with this buzz and dont want/think the BB guys will swap it out for a 3rd time. I wish it wasnt this way.
Looks like I will have to pay more for a panasonic which is uglier in my opinion. I hope the panny doesnt do this.

My 58c8000 will be delivered this week. I was looking at the user manual and found the entry pasted below in reference to mounting the TV to the stand. Is there a reason why the instructions state "50 inch model only". Aren't the stands the same for all the displays, or does the 58" and 63" come with the stand mounted?


FROM THE USER MANUAL:

Follow the steps below to connect the TV to the stand. (50 inch model only)
1. Connect the Guide Stand to the Stand using five screws (M4 X L12) as shown.

2. With your TV upright, connect the TV to the Stand. 3. Fasten two screws (M4 X L10) at position 1, and then
fasten three screws (M4 X L10) at position 2.
✎✎NOTE
xxMake sure to distinguish between the front and back of the Stand and Guide Stand when assembling them.
xxMake sure that at least two persons lift and move the PDP TV.
xx Stand the product up and fasten the screws. If you fasten the screws with the PDP TV placed down, it may lean to

Before I bought my C8000 I came to these forums and read all about this "buzz." It made me a little scared and I became hyper-sensitive to the situation. As soon as I turned the TV on, the first thing i did was listen for this "buzz." It was there, but just slightly. The fan on my Wii is louder, and that doesn't stop me from playing Wii or returning the Wii for a quieter game console.

It's not a buzz. It's a HUM. This whole issue is kind of blown out of proportion. There's no need to get all dejected and start talking about buying a Panasonic, which has worse problems and is ugly to boot.

For anyone who hasn't bought a C8000 but is thinking about it, don't be immediately turned off by these complaints of a buzz. It's not really a buzz at all on my set, just a hum that is concealed by even low volume from my home theater system. As I said, my Wii is louder, and so is the hum from my fridge.

The TVs come with the stand already attached. For me it was a pain in the booty getting it to come off the stand. That's because I tried to do it myself the first time. It really requires two people. Just loosen all the screws marked "S" near the pedestal and lift it off. Then you attach a piece of black plastic with some of those same screws and you're done.

Hey guys,

The other day my wife was burning some candles near the TV. We noticed after a while that the soot/smoke (the next day) got on the blinds and on the side of the TV stand. I've been worried that some of it may have gotten on the TV and on the screen (it's a PN58C8000), however when we passed our fingers on the side of the TV (bezel) we didn't see any black stuff. Today my wife wiped the screen with the special cleaning cloth that comes with the TV, and she said nothing showed up on the cloth after she cleaned the screen.

Should I do anything else to make sure that the screen isn't damaged because of this? Needless to say we aren't lighting any candles near the TV now. Just because nothing showed up on the cloth, could the screen still be damaged or picture quality affected?

Thanks,
Ryan

watching normal tv and HDTV , and avatar and pirates of the Caribbean on blue ray, and some ps3 games

my blacks are black .. though i'm sure the vt25 has "darking blacks" but mine are black non the less. When I do go up to the tv i do see the green and blue in the black though, and maybe it would be darker if it wasn't for that. But there is no way I can say that it looks gray, not even close. The PQ is amazing on the tv.

It's not really a buzz at all on my set, just a hum that is concealed by even low volume from my home theater system. As I said, my Wii is louder, and so is the hum from my fridge.

Mine is definitely a "buzz", and its amplitude and pitch change with the brightness of the scene. (Seems to be the brighter the scene, the louder the buzz). On my set it's not a hum, it's a buzz. Similar to the sound that sodium lights make (but not as loud obviously). I would also say it sounds a lot like my mini fridge when it's running.

When the volume on the TV is above 6 or so and there is normal dialogue happening, I don't hear it unless I really try to hear it. I'm sure when I turn on my xbox 360, which is super loud, I won't hear it. Where it sucks is when scenes change, or during a quiet part of a scene. It's just buzzing away. For what it's worth, the back of the TV is about a foot away from the wall, so I don't think I'm getting a reverberation / amplification effect of the sound bouncing off the wall.

I am reluctant to jump ship and return it in favor of the Panasonic VT25, because that TV is so damn ugly (and has a smaller screen to boot), yet more expensive.

The buzzing sound seems to be coming from the back of the TV, from both sides, from the area of the back panel near top and bottom that is perforated (for ventilation, I assume). I'll bet if I put something over those holes it would muffle the sound....but then will the TV be able to ventilate itself properly??

I will be contacting Geek Squad today to schedule them to come out and witness it for themselves.

Also Line Bleed: last night I was watching Paul Blart: Mall Cop and it was during the scene when they are in American Joe's restaurant. I had one of the menus up on the screen (picture settings or something) and the menu was on the right side, Kevin James' face was on the left side, and the borders from the menu were projecting horizontal lines across his face. But as soon as I exited the menu, the lines went away. I haven't noticed it while watching any sports with scoreboards up, but I will keep an eye out for it.

EDIT: I also noticed that near the middle of the back of the tv, there is a perforated area in the plastic panel where you can see a circuit board of some sort. While the tv is on, there is a green LED light that steadily blinks on and off, constantly. Is this normal? Does everyone else's 58" C8000 do this?
post #319 of 5875
for the buzzing , onething that helps if you don't mind so much .. turn the tv a little

the buzzing is directional and changing the tv's position a little to the left or right can help

Predator Look?

I was watching movies over the holiday and on a couple them I noticed a three layer transparent looking halo around a moving character. This occured during two movies Apocalypto and another movie which I forgot the title. It only happened once during each movie and was repeatable by rewinding. It reminded me of the special effect in the movie Predator when the creature was in stealth mode. Anyone else notice this? I have a PN63C8000 and was using the PS3 and a Onkyo 608.

Thanks for checking this for me. I was wondering how you tried to check for the issue?

I didn't notice it until after about 100 hours of use on the set. I don't think I initially had the issue, however not real sure as I tried to avoid 2.35:1 content.

You will not notice the issue unless you are in a dark room. Also you have to look closely at the black bars. You will also not notice it on brighter scenes. I can easily reproduce the issue by using the default Standard settings and turning brightness up to 57.

I am not trying to be picky about the issue. I realize I don't watch TV very close to the screen, however I don't think it's normal for there to be green and blue pixels in BLACK. Also I only noticed because the screen is very washed out and blacks are more of a dark grey. You can also see the green and blue pixels dancing around in the content as well. Again you can't notice it from seating distance but this affects overall Picture Quality.

I called Samsung to report the issue, they wanted to send out a tech but I am exchanging the set anyways due to buzz so no point of having a service appointment.

My set doesn't hum. It buzzes, it's loud and its annoying. I can hear it OVER my Xbox 360, which is LOUD but the 360 doesn't bother me. I can hear it over dialog in movies with my volume on my AV receiver set to an above average listening level. I have come to the conclusion that some sets buzz louder than others. I went to best buy the other day the c6500 they had on display was a hum, the c7000 they had definitely had a buzz to it. So the frequency in which this buzz is an issue may be exaggerated but its definitely an issue. I guarantee if you had the set I have you would be singing a different tune.

Is it just the Star Trek blu ray that you see this on or all movies that have the wide aspect?

Is there anyone that can comment if this is just how Plasmas are? Should there be green and blue pixel noise in the black?

From what I understand this pixel noise has to degrade the picture quality, correct?

I take it this is a direct HDMI connection from the BR to the Samsung?

My B860 had this, and my 58C8000 has this. I don't know what it is, but it appears to be normal.

Actually everything is running through my AV receiver. I didn't have any issues with my last HDTV. I will try tonight with a direct connection. I doubt it will make a difference though.

Another person on another thread said that they were able to reproduce the issue for a Samsung rep at Best Buy. This was done via a direct connection from Blu-Ray player to TV via HDMI.

Hey guys, LOOOONG time reader, first time posting.

I had the B860 a few months, buzzer, drove me nuts but the PQ was amazing. Ended up returning the B860 and went a few months without a HDTV. Purchased the C8000, was watching the TV all day. NO BUZZ, light light light hum. Can't hear it without having my ear to the TV and having a B860 Buzzer, I know what the buzzing sounds like. So I lucked out with the C8000. Both were 50".

One thing I noticed, I find that the B860 had a better PQ out of the box, I didn't do any playing with the 860's setting, but find myself constantly trying to tweak the settings on the C8000 to improve the PQ.

Anyone have any recommendations? I've read about the firmware update (I still have to check what I have) perhaps I should run the color slides? I find this weird because the B860 looks perfect out of the box.
