To be honest the calibrator should have done this for you and if they were from a big box store then there service may well carry a 1 year warranty which would cover a return visit.

As for activating Eco mode I'd say it's up to you but it will mess up the black levels of your calibration. If you're okay with that then do it.
Thanks for your reply.

I which way the Eco mode messes up the black level? Coming from a Kuro, I sure care about the black level.

I noticed that in night mode, with Eco off, on dark images the screen gets darker to a point that it doesn't make sense. I can see the screen getting gradually darker or lighter before my eyes... I copied the settings to the movie mode, and I think it's the same quality picture (at first glance), where there is no artificial darkening.

Anyway, I'm amazed that the calibrator didn't know about the lock, he said it's not possible.... he is actually a reputable guy around here.

Eco mode will 'intelligently' dim the panel according to the brightness of your room, but a calibrated picture mode has already done that. Furthermore if Cal Night uses a different Gamma setting as Cal Day, then it likely has different White Balance settings too. So while Eco may simulate the effect of Cal Night while watching Cal Day, I doubt it would match an accurate Cal Night calibration.

As for the dimming you are seeing, my Canadian F8000 doesn't have micro dimming. If yours is a US model it probably does. If so, is it switched on? That's all I can think of. Sorry.

I'm wary of broadcasting the service menu fix but if you'd like it then feel free to PM me.

Thanks so much for your kind reply.

I'm somewhat nervous to fiddle with service menu. I'll ask again to the calibrator. Thanks again.

I was wondering if your Canadian Model has Cal DAY and Cal Night grey out or blocked in the service menu. Mine is from South America and I could not enabled CAl Day and Cal Night.... Do you know if I could unblock that option ????

Thank you

I swapped the HDMI cable and updated to the latest firmware. It still happens.

I have done a search through this thread and there doesn't appear to be a solution in place. Anyone know of any information on a fix?
Since it has been a month I thought I would update everyone on the screen going black for a couple of secs then turning back on problem. Unplugging the power cord and waiting for 1 min. then plugging the power back in has helped but only for a couple of days. Now the problem happens at least once an hour while watching TV. I know it's not the FIOS box as it happened when I was watching a DVD.

How long have you had your set? It sounds like a pretty straight-forward warranty issue...
StevenPK's Avatar StevenPK 04:13 PM 07-11-2014
mruschetti - my models Cal Day and Night definitely isn't blocked or greyed out inside the service menu nor has any other Canadian Samsung I have so far encountered. But it maybe that I am misunderstanding your question. If you're asking whether Cal Day / Night individual picture settings are themselves greyed out in the TVs picture menu (eg brightness contrast etc) after a calibration, then yes, they would be if the settings were 'locked' or set to "Fix" inside the service menu. If this second answer refers to what you describe then this can be unlocked inside the service menu. If my first response more accurately refers to your problem then I wouldn't want to risk a guess for fear that it may lead to further service menu problems.

I just bought a UN60F8000 from BB. Got a good deal on it too. But I'm having issues with the video processing and am leaning towards returning it. I see SOE on most of the FIOS movie channels regardless if Auto Motion is on or not. Most of the HBO HD channels have it. Wolverine had it big time. Some shows were bad too. Falling Skies just looked totally fake and phony. Under the Dome was watchable, though. It was also bad on a few blu rays I tested including Star Wars. Just looked awful.

My old Vizio LCD did not have this problem unless i turned the motion processing on. I also have glitchy/jerky video on a number of other channels, and some of the SD stuff just looks terrible as well. About the only channel that looks great so far is ESPN HD. I'm pretty bummed about this. Do I just have a bad video board or something? I shouldn't be seeing any SOE if Auto Motion is completely off, right?

Have you tried the "clear" setting? That works perfect for me!
JerryT0025's Avatar JerryT0025 10:29 AM 07-13-2014
I've tried clear, smooth, custom, off. Turning off film mode. Doesn't seem to matter. The only channels overall that look good are ESPN. I could live with some glitchy cable channels, but I didn't expect the blu rays to look so bad.
JerryT0025's Avatar JerryT0025 11:02 AM 07-13-2014
Odd. I just turned on the set, and the SOE is gone. Popped in Star Wars and it looks fine. Guess I'll give it a week to see if it happens again. Maybe the judder setting was stuck to on, and it's now reset or something.

I recently said I'd re-calibrate my F8000 to see if it had drifted much since the original calibration settings I posted but it would be a waste of time. I had the TV in storage since early January and it saw temps as low as -23F due to a horrible winter in Wisconsin. Anyway, I put a meter on it this morning, color was still excellent, Grayscale and Gamma were pretty good but that was with a setup including Smart LED OFF just as I had it when I posted the settings. I wanted to use the F8000 with Smart LED LOW and the resulting Gamma was the Before in the following graph.

To add, the F8000 is now wall mounted in my brightly illuminated office/cigar room with large fluorescents in the ceiling. The TV will never be used for reference (dark room) viewing and the only content source is a cable box. I boosted light output to 62 foot Lamberts and wanted a Gamma of 2.1. In order to do that I had to make some rather large adjustments in the 10 point Grayscale controls and I'm sure they would never work in anyone else's Samsung.

For what it's worth, I'm switching back and forth between Sprint Cup and World Cup this afternoon and the picture in the bright environment is superb.

I have a question for Comcast subscribers; do you experience major PQ fluctuations from the various HD channels and/or programs?
For example, watching 1 movie on HBOHD the PQ will be pristine, but the next movie on the same channel will be totally washed out and terrible... Could this be the result from upconverting 720i to 1080i?
I would love to hear some feedback from others with the same issue, this is my only complaint with the set and I would love to resolve it!

It's not the TV set, it's the content.

Is your cable box converting 720 to 1080? If so this could be part of the problem. Can you set it to pass content sans conversion?

Remember that with cable, signal compression usually causes some artifacts. At the signal source, every camera is different. They don't pay enough attention to standards.

Thanks Buzz, I was pretty confident it was a source issue vs the TV, but never thought to check my cable box settings! I will definitely look into it...

* Scaled Picturea from Actual 1920x1080 pixel sized Patterns.

Hi, you may find interesting to test your display with this Advanced Sharpness Pattern that is available inside the Ted's LightSpace CMS Calibration Blu-Ray Disk among with other 150 Color Reproduction Patterns.

This Sharpness Pattern is not limited to typical Black/Gray/White Background that all current calibration disks are using but at 4-Step (25%, 50%, 75%,100%) of 7-Color Amplitude (Gray, Red, Green, Blue, Cyan, Magenta, Yellow) Background...


Better View - Part of the Advanced Sharpness Pattern

This Advanced Sharpness pattern is a real challenge for any display, it's will uncloak problems of you current sharpness control setting or from other enabled enhancements that were not visible before.

You can use it to verify your current sharpness setting value that you have set using a pattern generator or other calibration disk pattern since all other sharpness patterns available are based at grayscale lines/backgrounds only.

These multicolored backgrounds and shapes/lines combination maybe some times will make you add 1 or reduce by -1 or more of you sharpness slider setting that you have already set based on other classic grayscale based sharpness patterns.

Just got my 75" and while it is a nice tv, I seem to have really bad light bleed. Is this a common problem? It is noticable in dark scenes for sure. And really bad on a dark screensaver like pictured below.

I am thinking about returning the TV.

While this picture makes it look worse than it really is can anyone comment on whether this is considered normal by Samsung?

Knowing Samsung, they would consider that normal. I've seen much worse than that. It doesn't look like you have Smart LED turned on. Turn it on to Standard or High and take another picture of the BluRay disc logo. You should see a huge improvement in person and in the picture you take.

Doesn't look any better with Smart LED on max. So should I return the TV and take a chance on another unit? Really not looking forward to that after getting it all mounted.

Are there any posted settings that don't require going into the service menu? My brother bought this TV and does not have the standard remote. I'm having a horrible time searching this thread and as I stated earlier links to posts are not working for me. I know other people's settings don't usually transfer over well but I want to give him somewhere to start until I visit him in a couple of weeks. I've got my hand out and need a little hand holding please. Thanks!

Depending on how much light output you want, try these for reference or the following post for a brighter picture. Put them in the movie mode if you don't want to enable CAL-DAY and NIGHT.

If you want the CAL modes it's easy but requires the older remote control. Borrow one from a neighbor. Here>>>>> Official Samsung UNxxF8000 Owners Thread

You may qualify for a free, standard remote from samsung. Go to their website and navigate to the TV's model number, there will be a link there where you enter some info.

I like the way the TV automatically dims at night (is this Eco setting?) But it dims a bit too much. If I play with brightness then it somehow knocks it out of the auto switching mode and I have to go back to factory setting to regain the auto mode. How do I bump up the dark room brightness?

Bump up the Backlight setting in Eco Sensor Mode up to 7

unexpectederror,

Try taking a picture facing directly straight on to the screen and at least 8-10 feet back. It looks like you're looking down towards the TV and much closer than the viewing sweet spot. Being off axis in this way will exaggerate the black level of your screen. It's hard to judge uniformity errors if you're looking at the screen off axis. Try taking a picture closer to the optimum viewing sweet spot.
