Go buy a microfiber cloth and some LCD cleaning solution. You might try the dry cloth first.

Then I saw the picture of the legs on this thing (I originally thought it was center mounted like the smaller models), and I now have an issue.

My TV stand is 60", and it looks like the legs flare out to 65" or so. If I have to get a new TV stand, it will be a domino effect that will lead to a new equipment rack, media cabinet, etc, which will make this TV quite costly in the end. What I was wondering is if I could invert the legs. I know it would be a bit less stable, but the TV isn't in a high traffic area. Has anyone tried this? Any reason it wouldn't work?

Here's my "artist's rendition" of what I'm proposing:

That's exactly what I would also need to do with the width of my stand. If the legs are made the same with no
Special keying or something like that then maybe it's possible. I guess only someone with a 75 might be able to
Let us know. I do think that Sammy made a dumb decision on the stands. Gerry

The TV was supposed to be delivered today, but UPS screwed up. I'll post an update tomorrow night when I get a chance to set it up.

Running unblock-us for 2 days now. I chose not to VPN the whole router, but only the TV itself. So, now I have a fully functioning modem/router (full speed)
and an F6400 with US apps. Many config options. Might be worth the 5 bucks. I see no slowdown, Netflix is smooth, even in 3d.

Hi all (sorry for the cross post but wanted it in this thread),

I purchased a 75F6400 from Amazon. I like the TV for the most part, but wanted some feedback on the edge lighting running "hot". Basically on certain scenes, especially gray and white scenes I notice the edge lights. It forms a lighter border around the picture maybe 1" or so in width.

It bothered me, so I called Amazon. They had me adjust some settings, but the issue remained. I returned the TV and got a new one.

It has exactly the same issue, but maybe somewhat less so.

I called Samsung. They told me to use the standard picture setting and turn down the backlight to 7 and wait a few hours and it "should get better???" Was this somehow training the TV to not output as much light? I didn't understand what was supposed to happen.

Anyway, so the question for you guys is: Is this normal? Do you see it on your sets? Should I return the set and get a new one? Do all edge lit TV suffer from the same issue? I have a 46D6000 and don't notice it, but maybe it is not apparent on smaller sets? I really wanted a Plasma which don't have edge lighting, but needed/wanted the larger size.

I tried tweaking the settings, but it still remains.

Thanks for your help and advice.

I have the 55F6400 that I bought a couple months ago from Best Buy. I had minor clouding and called into Samsung to send in a request for service. Samsung has been really nice and quick with helping me. The service tech guy called me right away and he already order me a new panel and it took about a week to get to me.

When he came to my place and looked at my TV he said that I had minor clouding. I am pretty OCD about the TV and there was just this one bright cloud spot in the upper left corner that was bothering me.

What I found interesting from the tech guy (who has been working for Samsung for 5 years) is that he said when Samsung makes a model of a tv they of course make thousands of replacements at the same time. So when people call in they can exchange them. The problem is that the panels are never perfect. Your basically gambling your chances to see if you get a "good panel." If you replace it, it could be better or it could be worst.

Now when Samsung runs out of replacements, to when the TV was first manufactored, they start building new ones with sometimes minor fixes they have experienced in the past. It's called a "Prime Panel." To which you have a much higher percentage to get a better more perfect panel.

I went ahead and replaced my panel and unfortunately the clouding was A LOT worse... The tech told me all of this before I replaced it and he recommended not to do it but he said it's my decision. I went ahead and did it anyway just thinking that it might be better. He said after he replaced it he can't put the old one back on because after they open the new box (New Panel) they have this whole restocking fee stuff... Tech said no LED tv is perfect and they are known for clouding a bit. Plasmas are the ones that have the perfect blacks and whites. Though, I like a picture that "pops" like samsungs do.

Well he said that I should replace it again when the "prime panels" come in and to call him in 90 days. He said he doesn't get paid if he comes out before 90 days to replace it again. (Why should I care if he gets paid when I paid $1400 for a new tv, Samsung should cater to me). It's basically another gamble just wondering if the prime panels do come it. Tech said I can replace the tv 3 times before samsung gives me a full refund.

I don't know what to do or if the tech is telling me is 100% true. So i'm deciding if I should wait and see if the clouding goes away in 90 days and call back then. Or just take my chances with another panel. I guess I have a 1 year warrenty with it. Tech was trying to make me feel bad if I call back within a couple weeks because it's saying to Samsung that the TECH didn't do his job. Confusing situation but hope this information helps with those replacing panels. And if anyone has any ideas on what I should do would be great appreciated.

Interesting about the "prime panels" I wonder if that is why they changed the version number recently on some models like my F6300.

Reversing the stands on the 75F6400 is a no go. They have a tab at the top of each post that is off-center to prevent you from doing such a thing. For a short-term solution, I ended up just putting a piece of plywood on top of my existing TV stand. Looks classy! smile.gif

Regarding the TV itself, clouding is pretty bad when the screen is totally dark (which I suppose is an issue with most edge-lit LED). It wasn't really noticeable with brighter content, so hopefully it won't bother me too much. A previous poster indicated that it improved over time, so I have my fingers crossed.

I will say that the 3D picture on this thing is stunning (better than any theater experience I've had). I'll need to spend more time with 2D today.

Thanks for the update on stand. Figured that they would key it somehow to prevent it being done! Hope the set works out for you.

Gripwhip - I have that band you describe around my 75 and 50" 6400s. However, they are only noticeable on all white screens. I don't see them with solid color screens and definitely not during any actual content. What is your backlight set to? Mine is 12 in Movie mode, and I will occasionally turn it down as low as 7 if I want to watch at night with no lights on (otherwise it can get too bright, especially in a fade to white). Anyway if yours is much higher it may be exacerbating the effect.

Bummer about the stand guys. Fwiw I always think that visually a set looks better on a (much) wider base. I bought an 84" credenza on eBay and it looks great though I recognize not everyone's set up or taste allows for this!

Please explain what they changed model number wise on the F6300 ?

I honestly feel I have a Prime panel

No clouding no flash lighting of any kind. No DSE and its super bright. Yes they make prime panels but there nothing to say they don't make a perfect panel every now and then .

The first manufactured 46 and 40 inch F6300s used panel version TS01, the new ones have TU02.

So by definition and the word of the Samsung tech quoted above the TS01 were Samsung first run panels good not great. Second run imperfections and improvements made TU02 Samsung Prime panel !!!!!

* happy dance, sitting and twerking so happy now.

Well maybe this is one guys word, if you are happy with yours don't worry about it.
post #497 of 787
I just got the 75" and love it. No clouding at all like some other members described. The only problem i have is when Clear Motion Plus is activated, the picture studders for about 3 seconds every minute or so. Its very noticeable and annoying. I havent played with the custom clear motion picture settings to see where it goes away and when i notice it.
post #498 of 787
Can someone comment on how bad the 'soap opera' effect is with clear motion off. I once tried to watch Boardwalk Empire on a 60 Sharp LED that had 240hz and there was no good setting to get completely rid of it. Hard to watch a period piece like BE or Mad Men when every few scenes it looks like it's being broadcast live.

I keep mine on the "clear" setting and never see the SOE on anything, from Blu-ray, streaming, DVD, regular TV. Even stuff like American Pickers that is supposed to look live looks pretty good. You can also turn it all the way off.

Putting it on "smooth" gives the SOE, but does look good when watching sports or certain types of video games (those that don't need precise timing), so it's good to have the option just in case.
post #500 of 787
I had a chance to spend some quality time with my 75F6400 this weekend (rare weekend when the wife and kids were out of town). I used Buzz's settings from the F8000 thread as my starting point. After watching a couple of 3D blu-rays, a couple of 2D blu-rays, and several football games, here are my thoughts:

Pros:
-3D picture quality continues to impress me. I see no flickering, no crosstalk, no artifacts. Looks better than any passive 3D setup I've seen (theater or otherwise).
-Black levels are surprisingly good for an LCD TV. The black bars during movies blend seamlessly with the black bezel, and shadow detail is decent.
-I love the size of the TV. I finally feel immersed in the material, which was my main reason for upgrading from 65".

Cons:
-Off-angle viewing is horrendous. My primary viewing position is maybe 10 degrees off-angle (can't really fix this due to layout of the room), and even at that slight angle there is some (albeit minor) picture degradation. Anything beyond 20 degrees is pretty much unwatchable. Coming from plasma, I knew this would be an issue but I wasn't expecting it to be this bad. Is it due to the particular type of panel that Samsung uses?
-Auto Motion Plus is useless (to me). The recommended setting from the F8000 thread was 10 motion/5 judder. With this setting, I saw heaping doses of SOE and lip sync issues in 2D blu rays. For football games, the ball would disappear mid-flight. I turned off AMP, and all of these issues went away. It looks like people have had success with the "Clear" setting as well.
-Clouding. The clouding is much less severe than when I first fired up the TV, but it is still there. I think it's somewhat related to the poor off-angle viewing, since I will see clouding primarily on the left side of the screen if I am slightly off-angle to the right, and vice versa when sitting to the left.

Out of those, the only one that really bothers me is the off-angle viewing (any tips to mitigate this issue?). I knew that going from plasma to edge-lit LED would involve tradeoffs/compromises, and overall I'm happy with the TV so far.

The bottom line is that when I slip on the ridiculous-looking 3D glasses, dim the lights, and crank up my Klipsch speakers, I truly feel like I have a theater-quality experience at home. And that's really what it's all about in the end. biggrin.gif
post #501 of 787
Yomike - congrats! And happy to hear you got a good panel. I have AMP set to Clear and don't have the issue you're describing. What source(s) do you use that exhibits this?

Tsaville - glad you had a quiet weekend to put yours through its paces. On the viewing angle there isn't much that can be done I'm afraid. It is what it is. We have a single long sofa which is used for 9x% of viewing so are lucky that it isn't an issue for us.

On AMP, yeah I use Clear. I know I always recommend that people start with Buzz settings but I always forget to mention this. Sorry about that!

Clouding may get better in time, or at least you may perceive as such as I did. There's also the rub out method. Dry micro fiber cloth, gentle circular pressing motion on the affected screen area. It worked well for me (even better on a prior Vizio set) so there is certainly reason to the madness, if not also method.

I haven't heard of the "rub out" method. Is this a common thing that people try for clouding? Any risk of damaging the TV?
post #503 of 787
I have a 2008 LCD and AMP has been off since then. I'm pretty sure that the SOE is the same..

I am currently looking to upgrade. What is the difference between the F6300 and F6400? Is it merely 3D or is there something else? Is the panel lottery here too and are the panels larger than 55" all made by Sharp too?

Thanks.

3D, microdimming, higher clear motion rate, touchpad remote, bluetooth compatibility with Samsung keyboard, and maybe some others (I'm not sure if the F6300 supports content mirroring.)

I'm an HTPC user (sorry I did not mention that but it is why I have 8000 posts as I'm in that section all the time) so some of these things are useless to me. Based on what you indicate, it is 3D and microdimming that I would mostly benefit from. I'm not a huge fan of 3D but microdimming seems to be a good thing for an edge lit display, right? And what about the panel lottery? does that exist in this series too?

Microdimming has its fans, yes. I don't think it's critical, but nice to have. For me the price difference between the F6300 and F6400 was only $100, so I went with the F6400. But I was also way more interested in content mirroring (Samsung smartphone), the touchpad and voice activated remote, and other things that might not be of interest to you.

Some do use different panels, but my UN55F6400 has a Samsung panel. TS01, IIRC. I think all the 55" have Samsung panels.
post #507 of 787
That said, an IR repeater would be nice to fully utilize my S4 with my equipment in an enclosed cabinet but still I like a tactile remote like the H900 better.

Sorry Off Topic, Back to our regularly scheduled programming.

If I keep hanging out in here I'll end up replacing that 2008 LN650A40 in no time flat..

Yup. Sounds crazy right? If you poke around for posts about clouding, you'll inevitably find posts about the rub out method.

If you try it with the set on you can tell pretty easily how hard to press because you'll see psychedelic swirls where you're pressing. Otoh that really freaks some people out because it sort of looks like you must be breaking something!

Fwiw on my old Vizio it was astonishing what kind of physical pressure I could put on the screen in this way without doing any damage. It had horrible clouding in two spots at first. One all but went away after rubbing, the other was still a little visible during very dark content.

My Samsungs were better ootb but I did rub a little on my 75" which seemed to help.

The assembly tolerances of these sets are incredibly tight thanks to the industry fetish with thinness. The assumption is that cloudiness is caused by unevenness between different layers of the sandwich. So, rubbing gently theoretically forces the layers closer, from which they then spring back into (hopefully) better spaced alignment.

All this said, I'm neither an engineer nor a guarantor of this method's safety! So, try at your own risk, ymmv, etc etc etc. THAT said, and as I mentioned earlier, I'd recommend you do some searches and see what other people say about it. It may help alleviate concerns.
post #509 of 787
Hi -- I have the 55 inch version of this set. I'm using the ARC connection back to an Onkyo NR-709. Starting just after I updated the TV's firmware (yes, my fault, but ANYWAY) a couple of weeks ago, almost every day when I come home from work the receiver has been turned on; the TV itself is not on. I looked through the TV settings and don't see a "turn on the receiver at a time of day" settings, nor is it the same time of day anyway. Does anyone else have this symptom, or suggestions?
post #510 of 787
So I tried the "rub" method last night and didn't notice any immediate benefit. I watched a movie, and the clouding was pretty bad during the beginning. However, by the time the credits rolled around it was barely detectable. I have no idea if the rubbing had anything to do with it, or if the TV just got better as it warmed up. I'm somewhat encouraged, but I hope I don't have to warm up my TV for an hour every time I use it. smile.gif
