First off, I should mention that my display is a PN58C8000 so any answers to the following questions about running the ADC/WB calibration option for the various inputs (HDMI, AV, Comp, PC) need to be applicable to it--

1) Should the RGB color range for the 8x8 black/white checkerboard pattern be 0-255 or 16-235? I've read through this entire thread and see that one or the other has been used, but no clear explanation as to why either one was chosen over the other.

2) Notwithstanding whatever the right answer to #1 above may be, I've used both 0-255 and 16-235 successfully on both the AV and HDMI calibration options but I keep getting "Failure" on the Comp (component) calibration; what am I missing/doing wrong in trying to get the Component input to calibrate successfully? FYI--not only have I tried both RGB ranges, I've also tried them with both black and white in the upper-left corner (i.e., 4 different pattern combos in all)...still no dice.

3) This may be moot given the results in #2 above, but I've read posts where some folks detailed their instructions by stating that the source needed to be connected to HDMI1 (HDMI/DVI) and others who stated that the source needed to be connected or HDMI2 (ARC)...so, which input should the HDMI source be connected to...or does it technically even matter?

Observations during/after performing the ADC/WB calibration:

a) I do not see/get the bouncing small square during the calibration process that others have reported in previous posts; I do not know if the bouncing square is displayed only on LCD/LED and/or older plasma models, but I did notice during the process that the screen intensity brightens in small and infrequent steps before I am eventually presented with "Success"; subsequent attempts to (re)calibrate HDMI (and AV) after an initial successful calibration take but a few seconds before those attempts return "Success" as well.

b) After I had obtained a successful calibration, upon performing a factory reset and/or power-cycling my display via the remote I discovered that the calibration didn't take hold as the images were still dark (I did an A/B comparison using a movie scene I put on screen right after the calibration but before exiting the Service Menu). I redid the calibration except this time I did a Mute-Mute-Power Off afterwards since supposedly that keypress combo saves (any?) changes made in the Service Menu; dunno if that really did the trick but whatever--this time the image wasn't dark.

I don't really use the Component (and PC) inputs a whole lot but the OCD in me still wants to get at least the Comp calibration to pass successfully since every once in a blue moon my kids want to play their Xbox360 on my display and as such, I connect the 360 using its component cable--thus it would be nice if I can get the Component input calibrated successfully/correctly.

Thanks in advance!

P.S.--LOL this was my 777th post...if only that meant I hit some sort of jackpot!

Thank you to whoever recommended the checkerboard pattern! I made the same mistake as the OP and wound up with the pink screen, too.

I pulled up the video linked below on my Xbox One and kept backing it up so it stayed up for the duration of the calibration run. Voila! Problem fixed!

1st_Y_GL is grayed (Disabled)

Hellow everyone, I'm happy to have found this page because i just mess up my parent's tv.

I did the AV Calibration and all that stuff. The TV is a Samsung UN40EH5300; I have tried with the Four square black and white pattern but it continues showing "Failure".
I have read all the post, and I think the problems is that the "1st_Y_GL" in ADC Results iS NOT enable, so it is impossible to change that value.

is there any solution?

I hope you can help me, i really appreciate it.

Thanks.

Hello SXMAN, i have the same problem right now, ADC Result (1st_Y_GL) is disabled and cannot be changed, and i think it is the core problem, and the reason why my AV calibration Fails.

Do you find the solution?
Could you help me please?

Thanks a lot.

mute-1-8-2- pwr
SVC tab
Look for test patterns
scroll through the patterns until you see the checkerboard pattern
select that pattern **
go back to the ADC/WB
ADC
hdmi calibration
start the calibration.

Took about 3 seconds and it brought my tv right back to how it was before.

Hope it helps
Thanks - this suggestion helped a lot. Please note my additional additions

ALL HDMI Inputs populated, with, on my set, HDMI 3 (ARC) connected to my AVR.
All Colour Custom Values, 2/10 Point were all set to Zeroes, or Factory Reset Values
Then I did the ADC HDMI Calibration with the Checkerboard Pattern after writing down the current ADC Result Values FIRST! (Sometimes values get Zeroed with the failure, or changed to 255 or some other value. So better safe than sorry!)
Mine `Passed' and that cleared the `Failure' Beautiful results! Will let run today then calibrate tonight.

** PN64F8500: SVC > Test Patterns > HDMI Pattern Select > 6

UN65HU9000 - No Patterns coming up under Patterns. Can change values but nothing showing to get to CheckerBoard. Inputting external checkerboard pattern gets upconverted to the 4K version and results in Failure.

Due to there being no Patterns, ended up with Purple Screen:
Fix: ADC/Results. Before HDMI Calibration: 131/131/131:69/69/69 after and getting Purple Screen: 131/131/131:255/69/255. Just put the 255s back to the Center Value - Voila - Purple Screen gone.

Addendum on the PN64F8500 - had to balance between the SM WBs and the ADC Results. Below 40% is falling off and had to be boosted the max I could go. It appears something going on in the set. 40% and up OK - will just leave the set alone. When it quits, then I'll worry. I'm hearing other 8500 owners also starting to have issues. (Heat kills!)

HDMI Calibration Fails Samsung LN-T4661F

Hello,

I replaced blown capacitors on the main board for startup problem. Now the set turns on and now the HDMI Calibration fails. It looks like it tries to Calibrate, the picture becomes nice and clear for a split second then goes back to a Blue overall tint on a very washed out picture. I don't see anything in the service menu for displaying a checkerboard test target like some posts have talked about. When I select Calibrate it just runs through them and they all pass except HDMI

Any thoughts?

Thanks, Dan

HI..I have unfortunately joined the HDMI Calibration Failure ranks. My model is UN55ES7100. I tried using the method of bringing up the built in checkerboard pattern (called a "cross" pattern on my SVc menu, but when I back out to go to ADC/WB the pattern disappears. Am I doing a wrong key sequence, or is it just a particularity of my model and I will have to try and use a static test pattern from an external source? One thing I noticed is if I activate the HDMI Calibration sequence, the little box does not move.

Thanks..Steve

Steve, I'm having the exact same issues as you... Don't know where to go from here as I've tried an external test pattern which fails all the same... Can anyone shed some light?

Is there anyway to get the PS1D550 to enable usb Recording ? from the box my remote has the option but when I press it it pops up "Not Available" on the screen..

does the 7000 hack unlock this ? or is it missing the hardware ?

Hello to all, I have been reading this whole thread and one thing that I can report back on is that you guys have been using the incorrect patterns. I have attached the correct ones to use ie. 6 x vertical squares and 8 x horizontal squares with black square top left, if your result is failure invert the pattern for top left to be a white square. Btw these patterns are a replica of the ones residing on the tv, only slightly better and cleaner. If you want the ones with colour pm me.

Proper method that works for my set being in an area (South Africa) with a PAL tv system.

The patterns have to be displayed in full ie. no black spaces on the sides or the top and bottom.

Input all the results from the service manual for 2nd R,G,B_L and 2nd R,G,B_H across the sources of AV, Componenet and HDMI

1.
Apply the Chess SD pattern to AV input (composite) of your display confirm that the source is set to AV enter service menu. Go to adc/wb -> adc result and write down all the value's, you need to confirm that the result is more or less the same as that specified in the service manual for your model tv. If in a PAL area apply the pattern in PAL format from your dvd player or bluray player if in a NTSC area apply in NTSC format, go to calibration and calibrate wait a short while and you will be presented with success.

NOTE, Y_GL is of utmost importance, it has to match or be above that specified in the service manual. The only way of confirming if greyed out, is rooting the tv and using some code. Pm me if you need assisteance with this.

2.
Apply the Chess HD pattern to the component input at 720P 60Hz and calibrate.

3.
Apply the Chess HD pattern to HDMI/DVI input YCbCr 444 at 720P 60Hz and calibrate.

Power cycle tv set your favourite settings and enjoy.

I am sure this will help a lot of people, all that remains is to calibrate the pc input, any idea's as to how to get the tv to accept a pc input signal for pc ADC calibration of the pc input?

Please could someone post their tv's untouched pc ADC results.

Yes but still can not access pc adc calibration that way. To access that you need to add pc as a source input in the config menu, you will then be able to view the adc result for pc after selecting it in the service menu. Unfortunately however unable to get it to link to any input source when pc source is selected.

It seems that there are 2 steps to the ADC calibration for the AV input.

Once again 1st Y_GL is of utmost importance for the AV result BEFORE performing the calibration.

Step 1 - apply a NTSC (not NTSC-J) checker pattern to the AV input and perform the ADC calibration for that input.

Step 2 - apply a PAL checker pattern to the AV input and perform the ADC calibration again for that input.

Step 3 - apply a 1280 x 720 60P checker pattern to the componenet input and perform the ADC
calibration for that input.

Step 4 - apply a 1280 x 720 60P checker pattern to the HDMI/DVI input and perform the ADC calibration for that input.

My understanding for the NTSC pattern before the PAL pattern on the AV input is first to map the 7.5 IRE NTSC analogue input to digital level 16 and then the 100 IRE PAL analogue input to map to digital level 235.

It also seems that the AV ADC calibration affects the HDMI PQ and perhaps the black/brightness/luminance level. After following the above procedure PQ for HDMI is amazing, colours appear natural, shadow detail natural and the least amount of banding that I have ever noticed. My satellite stb using 1080i 50 resolution PQ is also looking so much better.

I hope this helps someone.
