Ok, and now I've found one blue stuck pixel. So that's two on this tv. Again, neither one is noticeable at all when watching the TV. The PS3 black screen can be your enemy! Beware!

Any ideas if these can actually be "unstuck" or is this more of a permanent thing? I've heard about gently rubbing the screen, but that never worked on my XBR's stuck pixel.

Would you guys return it for two pixels? After the XBR ordeal, I don't want to get into that game again. Another consideration for me is the extreme goof the store did with regards to giving me the 850 when I ordered and paid for a 650. If I return it, I'll not be bringing back and 850, but rather the 650. I don't know if I could go "back" to that, as it were. I really like the thin dimensions on this set and the ToC bezel is awesome.

Maybe I can save up the extra money towards the end of the month, return it, give the store the chance to make their corrections, if they want to and either swap it for another 850 free (depending on how the store treats this issue) or pony up the difference and get another new 850 anyways.

After watching more of the Transformers Blu Ray, I am floored by the picture. Even after telling my somewhat OCD wife about the pixel, she said A) don't tell me about those things B) I don't care because this picture is ridiculous!

If you have to put your face like one foot from the screen to see the stuck pixels but won't see them during normal viewing, then it's up to you if you want to exchange it.

When you go to the page for, say, the 860, look to the right, about halfway down and click on download center

On that page you'll see PDF's for the manual and a quick setup guide. Here's the link to the dowload center page for the 860:

http://www.samsung.com/us/support/do...Type=D&vType=R

I think the specs pages were around pages 128, 143, and 145, or thereabouts, near the end of each of the manuals.

Well, at least I figured out what I'm going to do with regards to my 850. I'm going to wait until my 30 days is almost up (either that or until the 850 goes on sale). When I'm close to the 30 day window, I'm going to return the 850 and see what the store wants to do. At that point, they may just say keep it and not bother. If they do that, then I'll be sure to get another 850 and check it out for stuck pixels. If they want to give me the 650, then I'll pony up the difference and get another 850 anyhow. Either way, it looks like I'm staying with the 850. The picture quality is just THAT good! Also, I like the styling a LOT better than the 650. This gives me a chance to let the store decide how they want to handle their mistake. I'll be happy either way they decide.

Thx, yeah, I'd found it shortly after I asked you. In any case, what I noticed about the way the woofer was listed in the manuals of the 750 and 950 was that it was in parenthesis like this "(10W x 2)" below the regular sound specs of 10W x 2, so does that mean the woofer provides an additional 10W per speaker, or is it 10W total including the woofer? Because if the latter is the case, then maybe the 850 has the woofer afterall since sound is listed as 10W x 2 for the 850 as well.

In either case, I don't believe the woofer needs to be turned on, as the menu for sound settings on the 750 and 950 doesn't have an option for it so I think the woofer must be automatically on. The surround sound, however, can be turned on or off.

You definitely have to be within a foot or two to see the pixel. It's silly really. I know most LCDs have problems with this, but I think I'm finally getting past my point of OCD that I can actually live with it! I learned to live with it on the 40XBR2 and, for the most part, forgot about it entirely because it was usually 'invisible'.

What's the difference between a dead pixel and stuck pixel?

Ah, you're right. Wonder why the 860 would have 18 and the 850 only 12. I realize the 860 has an MSRP of $100 more than the 850 but the only difference between the two that I've found thus far is that the 860 has one more input of some variety.

Ahhh yes! It's the 6 month input!

A stuck pixel is a pixel that continually emits a specific color (red, blue, green, or white). A dead pixel no longer emits any light and is continually black. Be warned before you start looking for them, most LCDs will have some or at least one, especially screens as large as the ones we are talking about!

If that's the case, I've seen plenty of stuck pixels on LCD screens in my lifetime, but mainly on flat panel computer screens. I've always called them "dead" though, but they were never black, they were always white. In either case, do they get stuck via the process of the different layers of glass and whatever else is getting pushed together to make the screen? And is the process reversible... can they be unstuck?

In either case, if you're afraid to return it to your store because of their initial error in charging you for a 650 instead, I'd definitely get it fixed through Samsung and put your warranty to work. Pixel problems suck and typically only get worse.

Read my post above, I'm going to let the store decide how they want to handle their screw-up. Either they'll just say nevermind and let me keep it - at which point I may return it close to the 30 day window. Or, they'll want to give me the 650 at which point I'll pony up the difference between the 650 and 850 (it may be on sale by then), and exchange it. Honestly, these things are not visible unless you know where to look and are right up on the TV. I won't see it even if I know where to look when I'm sitting at a normal viewing distance.

AFAIK, there are some 'fixes' for this, but I haven't tried one yet that has worked.

From Samsung's standpoint, the cost to make the 850 an 860 is probably identical. I'm sure that extra $100 partly subsidizes the warranty extension.

Irunnoft, there's something out there for unsticking pixels that can be downloaded and burned to DVD. It really gives the pixels a workout. Alternatively, I've heard that Disney Pixar films are also good for fixing stuck pixels.

The colors are not quite right, when watching Directv it seem to be twitch (exactly what 120hz should not look like). Also in between scence and such when the screen is all black there washed out looking spots (flashlight effect I belive its called). Im praying that I just got a hold of a defective unit, Im gonna exchange it tonight and see. But if anyone else is seeing the same thing...I would like to find out before I go through the trouble and just return it and go back to the ol 750.

Any suggestions?


I don't have any twitching when I watch DirecTV. I do get less than HD performance, but you might need to check your settings for SD. Definitely turn off the 120hz. With regards to the splotches, I saw them just faintly and barely this evening when the TV was switching inputs. It was just before the Blu Ray player started up and there was a black screen. The black screen was nowhere near as black as the black screen that popped up between coming attractions at the beginning of the disc. I also saw it as I was powering off the TV. There's something about this "black" screen that's different than the solid black screens that are presented in films, TV and content. This screen is much lighter - like a dark, dark grey. It isn't pitch black like the screen is most of the time. That leads me to believe that there is something going on with the blacklight during this operation and that's what pushes those little white blotches out. However, I must stress, this DOES NOT HAPPEN AT ALL while watching the TV. The issue is so faint that I can't even see it in the daylight, but I did notice it tonight. It made me remember this post from earlier in the day and I wanted to respond to it. It may not be your set, it just may be something that happens for a brief moment as the TV is switching inputs. However, it is not the clouding issue that affected the XBRs. I know. I went through my fair share of those and believe me, I had no problems being vocal about that issue when I was experiencing it. So I'm not a person who lives in denial just because I bought a certain brand or model TV. That's part of the benefit of this forum - people who are honest about their purchases and experiences with their products. All that being said, I can assure you all that while watching the 300 in a totally dark room, I'm satisfied that this TV has no problems with clouding or mura. It's still the most amazing picture I've seen yet and I'm in no way unhappy with it.
post #79 of 5551
Thank you for your reply. It was really bugging me because my wife also noticed it right off the bat and she normally cant tell the differance between SD and HD on some channels lol. So I took it off the wall, lugged it back down to the store, swapped it for a new one, went out to eat, got home and hooked up the new one...phew. And thank goodness I had a defective tv!!!! The new one looks great so far, I only got to watch it for a few minutes and now it is way past nite nite time (new job in the morning). I didnt see the white blotches that I saw on the other one. I do see what your saying about it being more of a dark grey than a black. I can live with that as long as it was uniform. The blotches on the first set where always in the same spots and pretty large. Ill watch some more tv tomorrow after work and see what I see. If anything changes Ill post it here.

Oh, and looking at the back of the TV I didnt see woofers like the 750 had. Ill listen close to it while it is playing and see if I can find any hidden speakers somewhere that is not obvious. And the light everyone was asking about has setting for always on, only in standby, and only while playing. The melody (sound it makes when turning set on and off) has low, med, high, and off settings as well. Hopes this helps, if anyone has any other questions Ill be happy to post them. I have had 3 different series Samsungs, always changing when something better comes out. Its nice to work at a retail store sometimes hehe.

This is pretty typical among manufacturers. The 860 is only available to 'select' dealers. The issue is due to things like price matching and guarantees of lowest price and/or support for premium dealers that offer extra services.

Anyway, manufacturers from washing machine makers to cameras will offer a special 'version' that is unique to some set of retailers. The profile of qualifying retailers depends on the manufacturer and its concerns. It might allow them to offer special discounts without affecting price guarantees on standard items, or it might allow them to charge a premium on the special item. Special units are often offered to WalMart so they can advertise the 'lowest price' in the country.

Anyway, they will tweak one or two things, in this case the warranty, one USB port, and blue TOC instead of red. These tweaks are just so they can claim a unique stock number and usually don't materially impact the product. In this case, I would have guessed the 860 would only be offered through high-end, high service reatilers that discount less, but this doesn't fit with the idea that ABC Warehouse is one of the 860 retailers, does it?

Yeah, not really, and now many other discount retailers are starting to get the 860 as well. For example, Amazon was only carrying the 850 at first, but now are listing the 860 too. I really don't think the 860 is going to turn out to be some sort of limited edition set as some might've thought. I never saw any promotional material or press releases from Samsung saying that it would. Many may think an extra $100 is worth it for a longer warranty, an extra USB, and blue TOC.
post #82 of 5551
Well, correction.... There is a dealer listing the 860 for sale on Amazon. Amazon itself is not yet selling the 860. I can't wait till they do because they usually have the best price and I definatelly want to hold out for the 860.

Well, I have a correction to make. After watching more of the 300 Blu Ray, I could, in fact, see the white splotches in the darkest scenes of the movie. At times when the screen was completely black, I could see them, so maybe an exchange is in order for me, too. I still love the picture and, like I said, these don't show up in the daytime.

Any chance you could get some pictures of this splotching problem during dark scenes? Also, why wouldn't the splotches appear during the daytime during the same scenes? Seems that wouldn't make sense. If they're not appearing during the daytime, then maybe it isn't the dark screen which is the source of the problem?

hey SakeDrinker. are you buying/exchanging your new 850 at CC? asking because I live in charlotte and the best I've dug up so far is an 860 unit at tweeter - of course with worse pricing.

by the way - anyone who is comfortable buying from CC, their offer is ~13 percent lower than msrp*

* mods and vigilant avs members: apologies if this gets too close to talking about pricing - just give me a warning if that's the case and I will post this kind of info at FW or SD

This was also the case with the XBR2/3s. You couldn't see the clouding on these panels in the showrooms unless the room was mostly darkened or the clouding was very bad. The true test of clouding problems is always performed in a dark room (this usually means night) with no lights on. Then you'll know what you're dealing with. And, sad to say, this TV of mine has that clouding issue. I wish it wasn't so, but there you have it. I'll take a picture of it tonight.

Sakedrinker, please report back and let us know if your newly exchanged TV has the same clouding issue. If you've had two that have it and I have one that has it, then we might be looking at a legitimate problem with this set.

As much as I love this TV and the picture quality I've seen on it, I wasn't going to live in denial and just pretend that the TV was perfect. I'm willing to overlook some things, but the clouding, even though it isn't as bad as the XBR clouds I'd experienced in the past, is a disappointment.

I'm locked on to Tweeter for the 860 (if I go with that model). There is a sale on it and while that still makes the price "slightly" higher than CC's, if you throw in the $500 free gas deal, it blows anyone else away. I was thinking of trying to negotiate down another hundred or two, or maybe get them to throw in a mount. Still, considering the gas deal is pretty much same as cash, it makes the deal on the 860 better than even the 750 on sale at BB or CC.

Just out of curiosity, does anybody know if 650 owners had issues with clouding? Seems like I asked that question a week ago and I think I might have heard back that some were reporting the issue and some weren't. This very well may be a problem with any LCD I get.

Also, anybody know what the magic number of stuck pixels is for Samsung to dispatch a repairman to replace a panel?

it was your post about tweeter's vs. USA's pricing on the 860 that caught my attention a few days ago.

I got a friendly mod warning regarding pricing/retailer discussions on another thread - so i'm posting the info over at the sammy 2008 lcd thread on SD.

if you post/follow that community, please post info about your dealings when buying the 860.

I'm curious to objectively how the picture quality between the 850 and 650 compare..

Maybe I need to go to the store to look...
