I doubt the moderators would have a problem with people discussing copying service menu settings as long as we upfront about the potential dangers.

Here is my proposed disclaimer

THE INFORMATION IN THIS THREAD IS NOT INTENDED FOR EVERYONE

WARNING: Entering your HDTV's service menu and making modifications without proper equipment, training and experience (this includes entering the service menu to copy someone elses settings) is strongly discouraged by most AVSForum moderators as well as most professional calibrators.

By the entering the service menu and making adjustments you may inadvertently cause permanent damage to your HDTV that may not be covered under the manufacturer's warranty

While some data gathered suggest that when copied, Samsung 61A750 and 67A750 service menu settings can result in improvements over factory default settings; results will vary from set to set and are likely to tied to firmware version and screen size.

Those participating in this thread are aware of the risk involved and are taking part in an on-going experiment to learn more about these televisions and to discover within what parameters service menu settings can transfer from set to set. No one here is recommending you enter the service menu and attempt this on your HDTV, however if you want to join in the fun and you accept personal responsibility for all risk, feel free to contribute.

I do note that 1005.x is faster scrolling on the menus, faster HDMI handshaking, and that I have less of an issue with Expert modes. Also it kicked my settings somewhat back to normal.

I was tired of resetting and not getting anywhere after my settings got messed up, so anyway I am getting my TV setup again and noted that the grey scale ramps are grey with a light tint. Possibly from the hight and sitting angle. Though OEM was blue/green.

I am now at 155,154,155... it is difficult to get all at 155. Though it is good enough for me.

I am thinking of rewrighting the calibration to use calibration in the expert mode as those who have 1006.x or 1007.x may find it difficult as I did. Not that I just calibrated for one set of settings... I tried every LED brightness setting, and RGB starting points I could imagine using.

Lee has has 61" with an earlier FW I do believe, but Varus has a 67" with 1007FW? I'm just curious to see what your original default numbers were and if there is a connection with FW or size?

I can tell you both Varus and I have the 67" sets with 1007 firmware (I'm currently using his latest settings and very pleased) and when using Lee's settings we both noticed problems with red which really stood out on test material with deep reds and didn't take a lot of effort to notice.. Use a lot of test material and let your eyes be the judge... post you opinion when done. If you aren't 100% happy with either, revert back to factory defaults.

I haven't been around much the last few days, but if anyone has any suggestions or requests for potential changes to the first post in this thread...please do not hesitate to bring them to my attention either by posting them here or sending me a private message. I put that together in a matter of minutes and I am more than willing to make changes to it.

No SSE or bloomy colors on Kung Fu Panda, whereas before you'd notice a lot of it in Po's fur and other close ups of the furious five. Of course i usually use the Standard mode for TV (except HBO HD) and computer animated movies like Pixar and Dreamworks. My wife is a Twilight freak (yeah, i know) so i've seen it several times with Lee's settings, Varus's old settings, and his new settings. Again, the white skin tones (and there's a lot of them in a vampire movie) looked much better. Before, even Bella's skin had a kind of shimmer to it, but now it's flatter and much more lifelike. Just my two cents.

Also, some asked earlier about the Actu Gain and SB gain settings and i noticed Varus didn't have these numbers included in his new settings. Can anyone give me a "suggested" figure?


U guys rule.

In the user menu everything is the same as before except:

Now for the testing--I went over to my friend's house yesterday to help set up his new 67 with 1007.4 firmware. I first plugged in the CNET settings. The Delta E's are
GREYSCALE Gamma=2.80
0=40.5, 10=1.9, 20=7.2, 30=16.8, 40=15.6, 50=16.5, 60=16.0, 70=15.5, 80=16.2, 90=15.2, 100=15.4
COLOR
Red=28.1, Green=14.7, Blue=19.8, Yellow=2.3, Cyan=18.5, Magenta=30.9

After that, I entered in my service menu/user menu settings and measured:
GREYSCALE Gamma=2.23
0=34.2, 10=6.1, 20=1.2, 30=1.9, 40=3.0, 50=3.2, 60=2.9, 70=3.1, 80=2.3, 90=3.2, 100=2.9
COLOR
Red=2.3, Green=5.5, Blue=8.7, Yellow=9.4, Cyan=6.0, Magenta=6.5

Amusingly his red is actually more accurate than mine was but my efforts to get rid of blue push on my set dropped his Blue Y down to 6.7. Still close though and if his set is indicative of what everyone else will get, it looks pretty good. Hope this helps everyone and if anyone has any questions (or if I forgot something) feel free to ask

Blows the old settings away. I actually had trouble with blacks with the old settings, but the new settings are much much better in this regard. I havent used Lee's settings for a couple months now so i cant give a comparison to that, but i do remember having to adjust some settings to get the brightness of the screen to watchable levels. I only did a quick test with transformers blu ray and it looks good so far. When i have time, or when Lee puts out his new settings, i'll switch to that and see how it compares to these. Thanks Varus for all the hard work. It feels like i just purchased new gear with the new settings.

However, in both cases for my set (67'', FW 1006) everything looked good except that there was an overly warm/yellow cast over the picture again. It is especially noticeable on white text or graphics. I'll be going back to Lee's again.

It is good to have antiprnt's observations as another data point, but assuming he sticks with Varus' over Lee's settings, my FW version theory may be out the window regarding the two settings.

If I can find some decent equipment on the web, I'm thinking about picking up something and learning how to do this myself, it sounds interesting, but I'm not sure where to start? I'm not looking in going all out and picking up some thousand dollar equipment, but if they have something out there for "beginners" that works, I'd be interested.

Thanks

It almost sounds like the firmware loop tripped the reset to save itself from you.

Hopefully, you can get back to where you started.
