Samsung UN75F6300 - Clouding

post #1 of 28
Thread Starter 
Just purchased a UN75F6300 from my local Bestbuy. It was a debate between the 6300 and 6400. The 6300 won because I never watch 3D.

After playing around with the settings, I've noticed there is also a lot of clouding. Is this normal for the 6300? Is it less noticeable/non existent in the 6400 model?

I've player around with AVSHD 709 calibration and can't seem to get the clouding to go away.

Where do you have your backlight, contrast, and brightness set? Put it in Movie mode and try these:

Backlight 12
Contrast 90
Brightness 46
Sharp 0
Color 50
Tint 50/50

(I'd also recommend the more extensive settings I posted in the 6400 thread which I use for my 75"6400 and were adapted from a calibrated F8000's settings).

...then take that same picture. The current clouding you have is more than you should see at normal settings IMO.

If it doesn't get much better, try the rub out method. And finally if that doesn't work I would exchange it. You will always likely have "some" clouding with a screen shot like that. But in general there should not be that much.

IMHO here is no reason to suspect that a 6400, 7100, or 8000 will have less clouding per se. Rather, only more features that do more to hide the clouding. You could get a great looking 6300 or horrible looking 7100. Panel lottery exists even with sets coming off the line sequentially.

I'll try these settings and snap a picture when I get home. Thanks for your help!

I bought the UN75F6300 and already returned it after 2 days because of the clouding. Mine looked almost identical to yours with the most noticeable cloud in the lower left side of the screen. I tried rubbing, screw-loosening, but nothing worked. If you decide to exchange it, I'd exchange it with a different model. The UN75F6300 is just awful in my opinion.

I'm thinking about returning it as we'll. did you exchange it for another 75 inch Samsung or did you go with a different brand? If so, which model did you go with?

I have a UN75F6400, but I'm in the middle of exchanging it because of a scratch on the screen. My 6400 has clouding, too, but it is not nearly as bad as the 6300 I had. The clouding on the 6400 is slightly visible during dark scenes with all the lights turned off at night. I don't expect LED-LCD screens to be perfectly uniform but my 6300 was just terrible. When you make your decision, please let us know how it turns out. Good luck.

Since the 75" panels all come from the same source, it's possible that Samsung is sort of cherry picking or grading them prior to assigning them to one line or another. Related throught: since the 6300 was a late addition, I wonder if its existence is owed to the fact that the line was churning out a lot of "meh" panels that people wouldn't accept in $4-6k sets. Not that it should be acceptable in a $2800 set but you get my though. They had to put them somewhere...

Just a theory.

what panel version(s) are these 75" sets using?

here's what a search showed up:

Interesting find. I checked the box label and mine (6400) is a TH01.

that is Samsung (S-PVA) panel then

the real issue could be edgelit LED backlights don't work well for very large screen sizes like 75"

I have a 46" EH6030 with a TS01 panel and a limited full array (direct lit LED) backlight and don't really have any flashlighting or clouding.

Well mine is fine wrt clouding. Had a little bit and was able to mostly rub it out. Also, over time what remained seems to have improved, as if the set loosened up.

My replacement UN75F6400 is coming this Saturday. I will let you know how the clouding is on the new TV after I set it up.
post #13 of 28
My replacement UN75F6400 has no clouding I can see. I checked it against a couple of black scenes with all the lights off but I don't see any. I guess either I got lucky or UN75F6400 is really better with clouding. I can see some banding running near and parallel to the 4 edges of the screen, though. This was also visible on the previous UN75F6400. Other than that, the screen on the replacement is very uniform. Its box says the version is UH02.

was the previous one also version UH02? or was it TH01?

I too bought the 6300 before thanksgiving and some serious clouding. After several phone calls w/ Samsung they've agree to exchange it for the 6400. You really should give samsung customer service a call.

Thanks for this. I haven't had a chance to call them. If you don't mind, can you provide any details on how you got Samsung to help you out? Anything I can reference when calling them. Also, did they send someone out to see the TV before replacing it? How long did the whole process take?

It was actually relatively painless. I suggest simply using their live chat option as I preferred that over talking on the phone. Just make sure you're in front of the tv as they want to go through several brightness and settings checks. This took two separate chats with them. Ultimately, they determined my clouding problem did not require an onsite diagnostic from a tech and they would simply order the replacement part(s) and schedule service.

 

Fast forward two weeks and no phone call, so I called the local company based off contact details from a samsung email I received. They said the part order was cancelled and to contact samsung. I then called samsung who said the parts were on back order for an undetermined time and they would either refund or exchange my set. Another couple days later I received a call from samsung's exchange and refund dept to discuss my options.

 

All told, I probably have four hours vested in the drama but nothing too dramatic considering i was going to initially deal w/ the picture.

K so I've been told that the exchange and refund dept will be calling me within the next 3-5 days to discuss my options. I would really like the 6400.. Any advice on what to say? Did you say anything that pushed them towards replacing with a 6400 vs another 6300? 

 

Thanks for all the help so far.

The thought of upgrading to a 6400 never occurred to me until the nice lady mentioned it and I was actually caught off guard by the proposal. She checked 'local' inventory quickly and identified several that were available, no idea where they're getting it from though, and said it'll be painless.

 

I suggest simply being honest with Samsung. You're concerned about getting another 6300 w/ similar issues, but overall enjoy the Samsung brand. See what happens, they should be fair. Good luck!

Have you received your 6400 model? How and where are you getting it from?

Samsung sent a person from a company associated with them to do repairs; but the Samsung spokesperson emailed me back and said:

 

"~~Panel auth request declined by Product Support Samsung considers this small amount of dark and light areas to be normal and in no way affects the quality of the picture. The LED backlights are on when the TV is on, so when you don't have any signal going to the TV screen and the room is totally dark, it will have light and dark areas. Also, most customers drive the panel too hard. What I mean by this is that the customer has gone into the menu and maxed out all the picture settings. Example: Picture setting to Dynamic, Backlight settings, brightness and contrast settings are at their maximum levels. In a dark room you don't need the brightness and backlight settings set so high. This is inherent to all LED TVs, all manufacturers"

 

So I'm not sure what to do at this point... call and complain again? And do you have a picture of the new panel in all it's glory?

I would call back and complain and say that you paid a lot of money for this TV and that you've seen other LEDs with much less clouding. If you're not already, make sure you're exclusively speaking with their executive customer relations... I had Service Quick as the Samsung authorized repair company come out and replace it although they did ask me to send them a picture of my clouding so that they submit the photo in their Panel Authorization Request. That took a few days and they scheduled the service call which took less than 2 hours...

 

I don't have a picture of the new panel yet but i'll definitely put some comparison photos up when I get some time

Alright thanks! I'm on the 3rd one from Best Buy and this one is better regarding the cloudiness and flash lighting, but I'll definitely make sure to be speak with executive customer relations.

Wow. Sorry to hear you're having so many problems.

 

The 6400 I received isn't perfect, but a huge improvement over the 6300. Hope everything works out.
