In response to cheezomo I am talking about a guess a grey scale issue. But it does effect the over all picture. It is really bad when you are in dark or blue scenes. I will see if i can take a picture of what it looks like. Dont know how well its gonna come out.

Here is THX test pattern. As you can clearly see alot of green in greyscale.

OK, I did not return the set today. I have until Jan 7th according to the 30 day return policy. I ended up with an almost perfect blue and red and so so green. I am now using the following settings:

Dynamic
Cool2
Contrast: 90
Brightness: 45
Sharpness: 0
Color: 38

Color Weakness: On
Red: 3

These settings give me bright cyan and white bars and are pretty close in color when using green color filter. Still not perfect. I will keep trying.

Can you post a picture of your greyscale?

Here is one. I have no green like you. Picture did not turn out that good.

Which pattern are you using? I am using Avia's gray needle and pulse pattern.

try using the ones off THX optimizer on movie dvds. Green shows up more there then AVIA. I used toy story.

bent98, I will post picture later. All my DVD's are stored in a box right now. I was able to play AVIA from my storage device that has some of my movies ripped from my DVD's.

After looking at darker scenes in Dynamic mode, I did notice a pinkish tint on dark scenes. I turned off Color Weakness and it is a little better. That setting only lets you do one color and not the others.

Cheezmo, what are your thoughts on this?
The green is almost 15% on color decoder test pattern.

I would try seeing if MATR_CBG and MATR_CRG can be used to get the green color decoding balanced (NOT for any grayscale issues). I would use the "Gamma On" parameter to isolate green instead of using a filter. Can't make any guarantees, but that is what I would try.

As always, write down your original values and be especially careful adjusting Gamma On since if you set it to 7 it turns all the colors off and there will be no picture if you accidentally exit the service menu or lose your place without immediately changing it back. Values between 1 and 6 should isolate the individual colors and their combinations.

How do you get upgraded firmware-does a technician need to replace my digital boards? There are reports in other threads that the HDMI discrete code works in v. 1035. Given that discrete codes are a listed "feature" of the HLP series I think I should be able to get an upgraded firmware version to use them properly.

Is there any reason that I wouldn't want to upgrade? I currenlty have 1013 (April build / purchased in June) and am happy with my PQ.

I have 1035 firmware and yes the HDMI code does work on my remote.

Cheezmo. After looking at my picture what do you make of it??

It is really hard to tell with a picture like that (how well calibrated is the display on my laptop, what influence does your camera have, etc.). It does look like there is some green "blotchiness" in the gray pattern. If DNiE and Digital NR are off, it seems like that may be a player issue or indeed something wrong with the TV. How was the DVD player connected to the TV?

DVD is HDMI hookedup HDMI, SAT (DVI), XBOX Component.

You can see that green in greyscale on all inputs. Not a DVD issue.

But this is 2nd tv and 3rd light engine.

Several comments were made concerning the use of the expand option to limit the amount of overscan. Using component and DVI input, I don't seem to have an expand option available. Is this something unique to the 5063 and larger sets?

Thanks
Tim

Expand is only there for 720p (at least on my 5063). I just assumed it would be the same for the others, but you know what assuming does...

My HTPC is outputting 720p over DVI and I get "Expand" using the "P. Size" remote button. That was true with a HLP5063 version 1011 and a new one with version 1035.

From what I've read anyone who doesn't see "Expand" is probably inputting something other than 720p.

Thanks for the tips. I can check this with my D* input over DVI. My DVD is still 480I over component so that may be why I don't have the option there.

Right.

Thank you Cheezmo, I really appreciate your suggestions. I will try those two settings and will report back. So for the green I need to concentrate on making Cyan and White bars the brightess, right? If I can't get the same amount of green on all four bars?

OK, so I decided to get my set (HLP5063) ISF calibrated today.

The ISF Technician has worked with HLM and HLN models, but was having issues with my HLP. The settings that he was attempting to modify were having no effect. They were:

Red_Gain
Blue_Gain
Green_Gain

Red_Offset2
Blue_Offset2
Green_Offset2

Should these have an effect on the grayscale?

He then tried modifying the following:

Red_C_Coeff
Blue_C_Coeff
Green_C_Coeff

Red_B_Coeff
Blue_B_Coeff
Green_B_Coeff

They had an effect, but he described them as being course and not acting as he was expecting. Sorry I can't be more descriptive.

He had some information he had downloaded from either ISF or Sencore, but it was aimed at the HLN, HLM models not the HLP. Much of what it said did not appear to apply.

Help is appreciated.

Thanks,

Sad to hear that the calibrator was not familiar with the set. The XX_X_Coeff parameters are the ones that should have been used. The procedure is not trivial though. You generally have a choice of turning off CCA and leaving it off, then adjusting those parameters or doing the CCA calibration which involves turning it off, measuring the primaries and entering your target white point in the CCA menu, then turning CCA back on with a little bit of follow up tweaking to follow. I found on my particular chassis HL-P5063 with firmware 1014, leaving it off allowed me to get the best color decoding, etc. That basic procedure is described in the service manual which your calibrator should get ahold of.

I wouldn't be upset with him, but would expect him to learn about your set and redo it. Samsung is putting some pretty powerful stuff in their service menus, but how to use much of it is not well understood, even by the calibrator community, but we are working on it!

If he wants to visit www.isfforum.com and sign up there, there is information available to calibrators there that should help him out.

Thanks Steve!

What is CCA?

I also have the 1014 firmware like you.

Does someone have a spreadsheet with the 1014 default values? I found one for the 1011 and another firmware, but not the 1014.

Also, are the SM settings different for each input or do you only adjust them once for all of the inputs.

One thing he also did was do a AutoColor reset. It changed the values for the gain and offset2 but it did not improve the puicture. He has since put the values back to default.

Can the service manual be purchased online?

Thanks,

-Tony

Tony,

yes, you can order the service manual from http://www.samsungparts.com .
Mine is on it's way!

Anyway to buy a PDF of it or something?

I believe dvi, hdmi and vga all share same settings and both component share each other, and all svideo share yet another. Someone correct me if I'm wrong. Hmm I also have 1014 firmware.

I'm wondering about this, because I changed the gamma setting to 8 while in DVI, and then shut down and went to Component 1 and checked and it was also set to 8. Maybe I'm crazy...I don't know.

-Tony

Maybe the defaults were different. I'm only using hdmi and dvi so I can't check.

Well I guess I could go in thru dvi and see what it says. I was in hdmi when I changed gamma from 8 to 0.

You might also have him contact SethS who consults with Samsung and has done several HLPxx63 sets with good results.
