Under the "WB" section I see "R_Offset", "R_Gain", etc.

Is "Offset" the same as "LowEnd" and "Gain" the same as "HighEnd"?

Also I remember seeing the first line is "P.Mode = Dynamic". Is this something I need to change? I don't want dynamic anything I believe.


Thanks!
Paul

Yes for WB offset and gain. Change Dynamic to Movie.

Well I saw Norman116 file that he had done for an HLS DLP and I used that format to put an excel spreadsheet to record your settings in the service menu for the HL61A750. I have three sheets in the workbook, the Srv Man Defaults, New (out of the box readings), and calibrated. On the New and calibrated sheets, you will need to change the values to what you have. I just copied the service manual default sheet over. The Srv Man Defaults are out of the Service Manual, which I recently bought. And as Norman said in his reply, if you use the "Track Changes" feature in excel you can trace what you have done.

Hopefully this will help someone not do what I did, change the readings and I didn't write the "out of the box" settings down.

Lots of great posts here by all!! I'd like to get a calibration guide together and add it to the 750 LED series FAQ. docrings, curttard, rahull, golferdude, scooter, anyone, would you guys be willing to help summarize your experiences, and write up a calibration guide for our sets?

Something similar to the guides Docrings wrote for the HL-S and HL-T models: http://www.avsforum.com/avs-vb/showt...9#post14280189 (some of which may not apply to our sets).

I don't have too much experience doing an HCFR cal, but want to give it a try, and am kind of confused by all of the different procedures, and versions of information. Definitely seems like there are multiple ways to achieve the same results, (like calibrate Dynamic mode cool1vs. movie mode warm 2, do stuff in desaturation). It seems like different people have done it different ways, but achieve similar end products, so maybe we will end up with a couple of different methods.

Are you guys that did your own sets willing to write up/discuss your procedures so we can come up with a guide (or guides) we can add/link to in the 750 FAQ?

Thanks,

- Mike.

I would be happy to help however I can. I am still learning so not sure if I am at a point to put anything together.

I am just now getting into the service menu and figuring out what steps to take and when. But once I get a good result, I would be happy to share it.

Fantastic thread! Thanks to everyone for posting advice and their personal experiences.

I've been trying to calibrate my HL61A750 as well. I got a Eyeone LT along with Digital Essentials HD basics Bluray, downloaded and burned the AVSHD709 Bluray formatted DVD and have been using HCFR to take readings with.

For my first attempt at calibration I only used the Greyscale & Colour Calibration for Dummies Guide. I managed to get my Greyscale spot on but got stuck when it came to getting my primaries and secondaries corrected. This was due to the fact that I didn't know what controls did what in the service menu.

Then I stumbled upon this thread and the steps people have been taking here. I've tried following some of the advice here, but I still can't get my colors right. Every time I try to dial in new settings to correct colors using the Desaturation menu it might get x and y closer on a couple of colors but it throws every other color off. Going back in to adjust for this simply throws the colors that were correct off as well. I must be missing something here.

Here are the steps I've been taking:

1)Calibrate greyscale with expert mode on (using Calibrated as user mode)
During greyscale calibration the only thing I'm adjusting is Contrast, Brightness, R_Offset, B_Offset, R_Gain and B_Gain.
2)Turn off CCA, record values using the first three test patterns in the service menu
3)Dial recorded settings into the CCA menu, turn CCA ON, Save and spread.
4)Take readings of primaries and secondaries using the second set of test patterns in the service menu. Note that I've been doing this with CCA and Desaturation ON.
5)Dial corrected numbers into Desaturation menu with CCA and Desaturation ON (I noticed that the Desaturation entries seem to take affect when you switch to a different option within the menu). I've got sRGB selected in the user menu, so these are the only numbers I adjust.
6)Go back and recalibrate greyscale.
7)Take readings of primaries and secondaries again and dial in corrections in the Desaturation menu.


Is calibrating greyscale first screwing me up? Another thing to note is that between calibration attempts I've been manually setting things back to defaults. Should I be using "factory reset" in the service menu instead?

Thanks ahead of time to anyone that has any advice or suggestions for me.

Greyscale calibration and primary/secondary calibrations are independant of each other. One should not affect the other (or at least they shouldn't). I wouldn't do a factory reset. You never know what that's really going to change and that will reset everything. Not just CMS changes.

I haven't actually had a chance to calibrate one of these yet, but I have a friend that has the 550 and I will be calibrating his soon. I'm looking forward to it. If I have anything to add, I'll post it here.

I'll beg to differ to what Nichol2 says only regarding these DLPs. Normally Grayscale and primary/secondaries calibration are independent of each other. Not the case with the Samsungs and their CCA system. I have not done a 750 yet but have done quite a bit of work with the 650s (which are the bulb based set). The CCA system in these Samsungs are implemented very well. Calibrate CCA first. Once you get CCA nailed you will find that you will have to make minimal changes (if any) to the WB (White Balance) menu. Here are a couple links. One for grayscale and 1 for CIE. This particular calibration was done strictly with CCA. No adjustments made to White Balance. The only thing these Sammy sets are missing is luminance control for the primaries / secondaries.

The steps I followed.

1 Set and spread CCA
2 Adjust grayscale in WB
3 Adjust gamut in DESATURATION

All measurements done in USER MENU after adjustment.

Thanks scooper and rahull for the replies

I'll try setting everything back to defaults including my WB and start again.

Regarding the CCA adjustments. All I need to do is punch in the numbers taken from my readings without adjusting them first correct (so I wouldn't be putting in only a percentage of my readings)? I'm using HCFR so the Y reading looks to be displayed correctly (no need to multiply).

Yes, take readings with CCA off, insert readings on CCA, turn CCA on, spread.

One more quick question.

Is there a way to exit the service menu without powering off the TV?

Thanks...

Don't think so.

If you have a remote that can be programmed with "hex codes" (RTI, for example), then you can set up a couple of custom functions:

Macro 1: To Enter Service Menu: "Info" followed by "Service Menu".
Macro 2: To Exit Service Menu: "Service Menu" followed by "Service Menu".

"Info" hex code:
0000 006D 0000 0022 00AB 00AB 0014 0040 0014 0040 0014 0040 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0040 0014 0040 0014 0040 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0040 0014 0040 0014 0040 0014 0040 0014 0040 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0014 0040 0014 0040 0014 0040 0014 0714

"Service Menu" hex code:
0000 006D 0000 0022 00AB 00AB 0016 003F 0016 003F 0016 003F 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 003F 0016 003F 0016 003F 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 0016 003F 0016 003F 0016 0016 0016 003F 0016 003F 0016 003F 0016 0016 0016 0016 0016 0016 0016 0016 0016 003F 0016 0016 0016 0016 0016 0016 0016 003F 0016 003F 0016 0715

In other words, while the TV is on, simply invoke "Enter Service Menu". When you're done with the service menu, simply invoke "Exit Service Menu". Yes, exiting requires *two* invocations of the "Service Menu" code (to get past the infamous "aging" non-error code). One button press to get in, another to get out. Nothing could be simpler.

If you have a Logitech remote, such as the 880, sent an email to customer support and ask them to add these two code sets to your profile. After they are added to your profile, program them into your remote as separate soft buttons or as the soft button macros indicated above. If you program in two separate buttons, for example "Info" and "SM,' then to enter the service menu press "Info" followed by "SM," while the TV is on. To exit the service menu, press "SM" followed by "SM."

To learn more about this sort of thing, try visiting www.remotecentral.com.

Pasted from <<a href="http://www.avsforum.com/avs-vb/showthread.php?p=7766442#post7766442" target="_blank">http://www.avsforum.com/avs-vb/showt...42#post7766442>

PS. The "Info" code above is actually the same code as the "Info" button on the TV's remote. In reality, it's already in the Logitech database.

I have the i1pro and the HL61A750. When I calibrate it and use the windows to calibrate the i1 won't reach the center of the window. Is it important to be in the middle of the window? Is it better to calibrate using a window image or a full screen image? Is there a good place to find a longer rubber strap to hang the i1 with?
post #75 of 123
I'm using an Eyeone LT which should be physically the same as the Pro. I have no problem getting it positioned anywhere on the screen when using it with a USB extension cable to my laptop.

When following a calibration guide it had me find the brightest spot on the screen to take readings from. For me this ended up being slightly below the center of the screen.

Regarding test patern windows. I've read guides that state windowed paterns are what should be used. I'm sure the pros here can comment on whether or not that's correct.

According to this thread it sounds like you want to use the full window paterns built into the TV when calibrating the CCA settings.
post #76 of 123
Thanks Donb1948 for the settings for service menu access. Those will come in handy once I get a unirversal remote. Which should be soon since I'm getting sick of having to use 3 remotes just to watch TV!!
post #77 of 123
Guess I should of done a better job of explaining my issue, sorry for that. The problem I am having is when hanging the i1 on the screen, the rubber strap from the weight to the screen holder seems too short. When I hang the weight over the top edge towards the back then let the i1 hang down, it is positioned towards the top of the image window. What is the technique most are using when taking readings, on a tripod or hanging?
post #78 of 123
I have used a tripod with the Spyder tripod suction cup adapter using a velcro strap as extra support insurance. Also, you can use the i1 suction cup mount with blue 3M painters tape criss-crossed for extra support.

I have a spare LE that was calibrated by Avical and it eventually developed the shadow. Warranty replaced the LE and I purchased the calibrated LE to keep as a spare, which I then fixed the tunnel collapse. Before I removed the calibrated LE I did a Digital>DMD copy to preserve the calibrated settings. Now, my question is, if I have to install the old calibrated LE should I do a DMD>Digital copy? I would like some clarification as to what both functions actually do and what settings are changed? I don't want to lose the calibration of the spare LE.

I calibrated a 750 today. I gotta say, I'm pretty impressed. It turned out fantastic. From where it started, let's just let the measurements speak for themselves!

Notice blue is off the chart!!!




What else is there to say!?
post #81 of 123
How did you perform it? What sensor are you using? What calibration software? That looks like HCFR.

Yes, HCFR. i1Pro is the sensor I use.

Does anyone know how to modify the gamma from the HLT service menus? My gamma is locked out at "OEM[4]" and I can't modify it. I've almost got my TV perfect except it's at a 1.8 gamma instead of 2.2

Modifying the gamma in the user menu does not help? That's what I used for the one I calibrated this weekend.
post #85 of 123
So maybe I'm confused here, but when I edit things in the service menu, it seems to be applied to the "Dynamic" mode, which does not let the user adjust "Detailed Settings" which is where the gamma is located in the user menu.

Is there a way to edit the "Normal" or "Movie" modes in the service menu?

You have to go to the WB menu and change the mode to Movie from Dynamic. Then everything you do will affect Movie mode.

I calibrated my 750 and my colors are close but have ups and downs along the 100 percent line. To get those closer do I have to just keep calibrating it?
post #88 of 123
Excuse me for sounding dumb, but what is CCA? And where can it be found in the service menu? I am in the process of calibrating my samsung a786 and have looked around the service menu and cannot find a cca setting. I have been using the wb movie with the usual gain/offset controls.

Most all Samsung LCD and Plasmas do not have CCA in the service menu. Only the newest line have this available. CCA is the starting place for adjusting the color management system.

Is this accessible via the remote menu's? The A786 is a recent model, a month old if that. I have options for color space via the remote menu's but cannot see anything specific for color management in the service menu.
