Try updating to the newest firmware.. I have the 60 inch.. And I noticed the dark scenes as well when i bought the TV without the updates.. Now with the updates it looks amazing! Do a update and it will be gone.. The 60 inch is amazing! The picture quality does really make a difference on the updates.. I have no complaints with my 60 now.. it's a beast..
post #1833 of 4993
It might be luck of the draw tho..
cause I have a friend who owns a 55 and a friend who owns a 60..
and I just asked them if they had any blooming problems..
both said NO.. The easy way to check blooming is to check movie credits
if there is a HALO around the letters.. or is it just white on the letters..
When I first got the tv i did notice this (very minimal) but after I updated..
Its been perfect..
Actually my 60 has had no problems at all no clouding, no flashlighting, no banding..
And the motion is amazing..
Im curious to know if the update fixed your problem.. or is it a bad panel?

Best thing is you don't need the disc to play. (Finally Xbox Gold paying off)

+1, I got Fable III and Crackdown that way...haven't played either yet.

Vevo and Youtube Videos via. the Xbox360 look awesome on the F7100.

I updated it to SW ver 1108 two days ago. I didnt see any improvement. watching the tv during the day it is difficult to see the blooming on dark scenes but it is very noticeable if the room is dark. Are you using the default Movie picture setting?
post #1836 of 4993
It may not be called 'blooming'. The issue I'm having is the darker areas of a dark scene have very poor detail. The definition is grainy and its as if the pixels are half inch boxes.

Maybe its films native 24p frame-rate.

LED Edge-lit sets like this have difficulty keeping uniformity on dim-solid color, moving images.

I have also in rare instances noticed very-mild horizontal and vertical banding.

Its not avoidable due to the edge-lit design.

Watch this video beginning at the 10:00 min. mark:

The screens and diffusers would have to be perfectly flat to avoid banding.

You're talking about "black crush" not blooming.

Black crush on the 7100 is most likely due to the source material ie your cable box or a poorly transferred BluRay. I would check some reference quality BluRays, if its still crushing blacks I'd exchange it.

I have the directv genie with HDMI signal. The PQ is amazing on bright scenes. I'm hoping it is settings/calibration. Any ideas what I can do? Since this is the only issue I am having, is it safe to say it is not a problem with the TV?

My first F7100 had zero banding/DSE (I'm not sure which term is more appropriate) prior to the moderate handling I warned about a few posts back.

Since it was so easy to cause the problem, I've been wondering if there's any kind of reasonable cure to the uniformity. I watched that teardown video you posted, and saw that the screen is a series of flexible layers. Based on that you might think laying the panel.flat on it's back for an extended duration might even the layers out...

Here is a clip. Imageshack crapped on the quality of the video but you can still see what I'm talking about. On the grey wall to the left around 2-3 seconds in and from 11-15 seconds you can see the blocks/squares. It is easier to see if you watch it in a dark room.

Looks like your talking about mpeg compression artifacts & gradients
https://en.wikipedia.org/wiki/Compression_artifact
That is inherent with Mpeg Compression, you can set Mpeg noise filter but may soften picture to much.
The source is usually the problem.
You can try to mask compression artifacts by using settings on post# 884, is a good starting point.
Lower backlight & brightness & eco sensor until artifacts are minamized

I hate to beat a dead horse, since I know I've posted a few times about this. I am still trying to adjust and get my tv to not exhibit clouding but I am trying to see if my expectations with edge lit LCD technology is realistic since I'm new to it.

Is it possible to get a 'cloud free' set and not see clouding on an all black screen at night time with the lights real low in the room? I am struggling to get results that can do this while still maintaining a bright picture. I am in game mode trying to get this going on. I have my backlight set to 17, contrast at 80. Brightness has varied since I am also trying to disable micro dimming as much as possible (I've tried both 44 for the brightness as well as 53, with RGB offsets then set to 8-12 to compensate for the black levels).

My set is not too bad clouding wise on the right side of the screen, but there is some decent size splotches on the left, especially the lower left. I reattached an image I posted earlier with the brightness cranked very high to show where the clouding spots are. I don't know if this is more than usual or about right:



It's a bigger set and from the success I've seen of some people on here, it sounds like downgrading in size causes this to be less symptomatic although I don't know if that's true.

Sorry to bring it up again. I'm about half way through my 30 day return period with Amazon and debating whether or not to return it for another shot (this would be my 3rd f6400 model). Maybe I'm being a bit too picky.

This is a MPEG Compression issue as posted above its called Macroblocking:

http://en.wikipedia.org/wiki/Macroblock

Its the source material for the most part and maybe a little of the HDTV's processing.

I just got my ES7100 65" a few days ago and have a question on getting the sound from Smart Hub apps to play through the receiver speakers. My receiver (Sony STR-DN1040) has ARC and I'm using the HDMI2 jack on the TV. Everything outputs to the tuner and the tuner then outputs to my surround speakers.

If I'm understanding correctly, I can use ARC to send my TV sound (originating from the apps like Netflix) back to the receiver and then out to my speakers without requiring another cable? Currently the sound only comes out of my TV speakers. Any help on this would be appreciated, as I'm still new at setting up systems.

I've been through 3 attempted repairs on a Samsung A850 panel- which was a really exceptional set.

I went through 3 exchanges of a Samsung D6900 due to dead pixels and banding.

I had 3 attempted repairs of a Samsung D6900 due to banding and 3D issues.

I had 3 attempted repairs of a Samsung ES7100 due to 3D banding, dead pixels and bezel light leakage.

I had 1 repair of the Samsung F7100 due to the power cycle issue and had a replacement smart touch remote.

Bottom line: the perfect HDTV, Samsung or other-wise doesn't exist.

Now my current F7100 is cloud free, flashlighting is only in 3D, banding is next to nonexistent, all the pixels work and there are the faint "pencil lines" to the left and right of the screen.

From reading these threads some smaller models are better, but not all.

From experience the only way to reduce clouding is to lower the backlight and use dynamic contrast or standard's micro-dimming.

Maybe, I never tried that.

I guess its a matter of how much pressure is on the panel structure vs. the effect of gravity (or applied force).

Hi there guys,

First time poster, but I've been following this thread for a while.

I just picked up a UN55F7100, and I absolutely love it. My question to you all is: I have a larger framed face, and especially bridge on my nose. I find the glasses that come with the set are relatively uncomfortable for moderate to long viewing, especially since the bridge is so small. I've been looking at the battery rechargeable glasses, but I don't know if they have a larger bridge, or is there something out there I should look at?

Thanks!

I got my UN65F7100 delivered today, and was lucky enough to receive a TH02 panel. Just got done doing the firmware update, factory reset, and calibration based off the one from LCDTVbuyingguide.com. So far, so good. I don't notice any clouding or banding or any of that. The only annoying thing is waiting until later in the week for someone to help me mount it. My old TV stand was too small to use as a temporary stand in, so it's currently just sitting on the floor.
post #1852 of 4993
How can you find out if you have a sharp/samsung screen and if it's a TH02 vs other kind? Is this only available if you take the TV apart? I do not have the box that came with the television.

There is a white lable on the back of the TV that shows it. Mine shows "Version No: HH01". To find out if it's a sharp or samsung panel, type one of the numbers (like TH02) in this forum search function and some threads will show up with info in them. I believe mine may be a sharp panel and after some miner adjustments, it looks remarkable, with no clouding, banding, motion problems, and only VERY MINOR flashlighting on a blank dark screen. I recently bought the samsung 60F7100, the samsung 40F6300, and the sharp 80" 857. All look wonderfull with no problems to speak of, so I wouldn't be overly concerned with what panel you have as long as there are no serious problems, wich can happen with any of them.

Congrats .....would u
Mind sharing where you purchased....just wondering since maybe some vendors have specific panel versiobs !! Thanks

I've searched through the thread and haven't really seen a definitive answer as to the best way to book this TV up to 7.1 surround. I have my receiver that I typically connect all my components to, then run a single cable to the TV. Is that not what will work best with this TV?

I too have a 60F7100, which has been claimed to have a Sharp panel, and it looks perfect except for very minor flashlighting. I have actually had three of them over the past three months (had to return them for non-panel related issues) and all of them looked great. Don't let the fact that Sharp made the panel bother you.

That should be fine, and what most would probably want to do, so the reciever becomes the "heart" of the system. But if you have an older reciever, that doesn't have ARC HDMI (audio return chanel) , then you might want to set it up differently if you want what to stream ( netflix, hulu, etc...), or apps to play through your reciever. Or if you listen mostly through the TV speakers and don't want to turn on the reciever all the time. There are several or more ways to do it depending on what you have ( dvd, games, dvr, cable box, etc...) and what you want. If you list everything, and your reciever, someone will be willing to help.smile.gif

YUP!.. i gots the 60 as well.. its been mint.. This whole sharp panel thing is all nerd bull... my friend has the 55 version and its the samsung panel.. And we thoroughly checked and compared the screens (with mostly blu ray sources) and there is no difference! they both look amazing,, we did the almost the same setups.. with minor tweaking to both.. The only thing he is complaining about is my screen is bigger.. he is thinking about going 60 now.. Enjoy your UN60f7100 its a beast!... this panel thing is just to try and find faults that are not there in my opinion.. Once we calibrated the TVs.. they where Identical.. I read that some people even exchanged there 60 for 55.. which I think is crazy.. why loose 5 inches of screen? because they read there is a shade of black that looks different? or whatever there claiming.. For the most part on these here message boards everyone is paranoid about every little detail on there TVs... No TV is ever going to be perfect..
If you have no clouding, banding,blooming,flashlighting etc.. Then you hit the panel jackpot.. Enjoy your TV!
post #1860 of 4993
I mainly was curious on the panel thing to see if there is a consistent pattern as to which panels have more clouding than others. I'm about to go to my 3rd f6400 because there is a good deal of clouding. That said, I have a 75 inch screen which may be more susceptible to thus and it may be an issue of having the back lighting too high at 16. Still experimenting. But definitely not just me looking for defects as shown in previous attached pics. smile.gif
