Panasonic PZ80/PZ85 Calibration Thread (Updated first post) - Page 81

Hi Everyone,

Is there a way to reset the settings in the service menu?

Great thread!

I've got the Australian version of the Z850. 65" model, TH-65PZ850A.

I've gone into the service menu and would like to know if these are the default settings as I purchased my TV from the store as it was there display unit on there showroom floor.

If they are not could someone please let me know. Thanks.

Service Menu:

A-CUT | 80 80 | 80 80 | 80 80
A-DRV | FC FC | FC FC | FC FC

unfortunately is not possible to reset settings in service menu

Are these your default settings or have you changed them?

My Colour was set to 2B but now I've set it to 3D as it gives much more life to the colour. I'll try this out for a few more days and see how we go.

Anyone with a PZ850, could you please post your settings as I would not mind trying it as well. Thanks.

I'll try your settings when I finish work.

Only Cinema mode has gamma even remotely close to the 2.22 ideal. Other modes have about half that (at best).

So are my settings ok?

I cannot tell you whether your settings are correct or incorrect because my TV has different SM defaults than yours. I hope that either these are your defaults or that you have written down all your defaults before changing anything at all. It seems that some values are usually the same for all TVs in the model range, which I have bolded.

It would be very unlikely that the default factory values for RDRV would be FC for all three color temperatures.

Larry

The reason I'm asking is that I bought this TV from the store and it was there floor/display model. So I'm not sure what my service menu should be on. As it is possible these sales freaks may have played around with the settings. That is why I want to check. If anyone can please post there settings it would be greatly appreciated.

65PZ850.

Also what should Color - 2B be on? Mine is on 2B. Is this correct?

In this case R-DRV is the reference, not the typical G-DRV. It can be at FC for all three color temp presets as long as the G-DRV and B-DRV values are different. Yes, it's unusual, but I recall at least on other PZ80 owner with the same thing.

I wouldn't worry about it; if you really care, you could always get the TV calibrated or buy an i1 display LT and do it yourself for cheap. Not necessary, though, unless you notice your grayscale being off. By the way, you have a PZ850 and this thread is for PZ80's/PZ85's.

I stand corrected. I just looked through my library of service manuals and the PZ80U is the only one that has RDRV set the same for all color temperatures. The PZ85, however, has different RDRV settings.


EDIT: Another correction. Sorry. The RDRVs are the same for the PX80U not the PZ80U.

For the PZ80U and the PZ85U, the factory RDRVs are different for the different color temperatures.

RDRV for Normal should be 2 less than Cool. RDRV for Warm should be 3 more than Cool.
GDRVs should all be the same.
BDRV for Normal should be 17h less than Cool. BDRV for Warm should be 46h less than Cool.


Larry

Do you have the service manual for the PZ850?

I agree that the service manual for the PZ80U uses G-DRV as the reference (FC for all color temp presets); however, the same manual shows R-DRV at FC in the sample data section on page 9. Also, some TVs have all R-DRV values at FC as factory defaults.

So, while it flies against the 'data shift from Cool adjust' you quoted, it still exists and can still achieve the same results (by compensating with G-DRV and B-DRV). I'm not convinced the settings posted above are messed with just because R-DRV was used as the reference and not the much more commonly used G-DRV. If I can recall where I seen this before, I will post a link.

Plas,

Don't use the sample values. They are identical in the service manuals for the PX80U, PZ80U, PZ85U, and PZ800U. The sample list is in a table designed to show the various service menu items. The values included are meaningless.

Larry

In that case, how would you explain Campiones's settings? I just don't think someone would intentionally modify all three presets like that.

I don't have any idea why. The sample values in the manuals I mentioned all are:
RDRV ...... FC
GDRV ...... F8
BDRV ....... D9

Every TV that I have seen in the px6xxU, px7xxU, px8xxU series came from the factory set with the specific offsets from Cool shown in the manual. In fact, with those units, if someone forgot to write down the Warm or Normal settings, we could reconstruct them using the untouched Cool values.

I'm not starting an argument. I'm just passing on information.

Larry

Ok. The main thing I would suggest to Campiones is that if the grayscale doesn't look screwed up in any of the presets (checking grayscale ramps and steps on AVS disc), then it would be best not to mess with it short of using a capable meter (as in not a regular spyder 2/3) or getting a pro calibration.

Hey guys, I've been observing this thread for some time now, I've owned my 46pz85u since last holiday season, but this is my first post. I know I'm gonna sound like one of "those people," but I've never really been thrilled with whites through an HDMI source with the set. Anything other than Cinema looks terrible, and I can't take Normal so I leave the temp on Warm, but whites just never look pure to me on Cinema/Warm.

Component looks the same, except I found that there's one service menu setting you can adjust on component that you can't with HDMI. I know it's been mentioned in this thread before, but it's the "Contrast" setting in the SM. With an HDMI source it defaults at "000," and adjusting the value has no impact on the picture. However, with component you'll notice a varying value next to "YMax," and altering "Contrast" does affect the panel.

Using component, I've upped the SM contrast (BE VERY CAREFUL with this setting, as I'm sure it could toast your panel if you up it too much) by 5 ticks, from 1F0 to 1F5. All the other service menu settings are at their default values, but here are my user menu settings:

Cinema/Warm
Picture - 65
Brightness - 48
Color - 40
Tint - -1
Sharpness - 50
Color Mgmt/CATS - OFF
Black Level - Light

My DirecTV box broadcasts at 1080i anyway, so I figure I'm not losing a lot by using component rather than HDMI. I'm sure I'm losing a bit of shadow detail, but I think it's a very slight amount after comparing with the HDMI input. I think these settings strike a pretty fair balance between dark/light room viewing so you're not sitting around your panel switching between Cinema/Custom/Standard depending on the time of day. I'm still getting some red push, but, as ElwayLite mentioned before, I'm willing to deal with a bit of it to make the rest of the colors look great.

Again, I know this issue has come up multiple times before, but if anyone knows of any way to brighten the whites with an HDMI source, besides upping the blue drive, please let me know. I love the PQ on this panel, but I don't want to leave my HDMI inputs as unused because of my stubborn eyes!

I posted this on the owner's thread as well since this place is a morgue.

Does anyone have their Color Matrix under Advanced Picture Settings set to HD?

Originally it was set to SD (Standard Definition), and I had my Sony PSP hooked up via component cable in Game Mode. I never saw the Color Matrix box active before, so I switched it to HD and it added some color detail that SD wasn't showing. Now I guess that all of my picture modes have switched the Color Matrix to HD, and I'm wondering if there is a reason I should switch back to SD or leave it on HD?

I'm not sure of the purpose of this option, and if it makes anything worse by having it set to HD now. Hopefully someone understands this, and can give me the right answer.

HD and SD signals have different definitions for the colors they are using. The color matrix option allows you to specify which color definitions are to be used to properly display the signal you are feeding to the TV.

This option is available only when the TV can't figure out which color matrix should be used; this usually include sources connected via component cables. When the option is grayed, I believe the TV is simply using the appropriate color matrix for the signal being displayed, regardless of what is currently selected as the color matrix. In other words, if the color matrix option is showing "SD" and is grayed because you are sending a 1080i/p signal over HDMI, I believe the resulting picture is identical to what is shown when displaying the same 1080i/p signal while the color matrix option is grayed and displaying "HD".

Thanks for your input, but I'm feeling ill at ease with the setting. I can change the setting only on my Component 2 input, and most likely Component 1. However, I can only change it when I have my PSP displayed on the tv. Someone was telling me the Color Matrix is like the tv displaying in RGB Full, so it's crushing blacks when set to HD.

However, HDMI 1, and HDMI 2 are greyed out ith the Color Matrix locked on HD. Before they were only on SD and now I'm worried that my colors are messed up because certain things seem darker. It won't let me change the setting on any other input, and even when I do change it back to SD every other input is greyed out other than the picture settings for Component.

If it was on SD to begin with I would think that was what it should have been on. It's a very confusing option, and you would think that HD would be a better choice but maybe it isn't. It won't let me change it on my HDMI inputs though.

Hey Guys...haven't been here in ages...I hope all is well!

I have recently been getting into using the proper OAR for SD content and would like to know:

Is it possible to adjust the side masks on the 85U, from gray to black? This is for use with any 4:3 content.

Thanks!

DUH!

Never mind...just figured it out...simpler than I thought!

Maybe you could share with us how to did it ? I'd love to get rid of the gray sides masks and switch them to black in 4.3

Hi,

I tried to calibrate my 42" 85zu today using the AVS HD 709 files on this site. I am using the AVCHD mp4 files from a PS3 connected via HDMI


In Cinema mode, my picture is set to 100 and I do not see flashing in the white clipping pattern. Is there a setting that preventing my panel from getting as bright as it should?
Is this something that can be adjusted in the service menu?

I've been working on a personal fix for the low light output in Cinema mode ever since I got this panel. I say "personal" fix because it's really a fix to me and anyone else who thinks Cinema is a little dark, not for those who love the display as is.

I think I may have come across a bit of a breakthrough, but I'd appreciate any feedback, positive or negative, if anyone decides to try this.

Using a component input ONLY (will not work on HDMI, and I know this automatically will cause a bunch of you to tune out from this, but broadcast HD maxes out at 1080i, so . . .) access the service menu. Then tune the following settings:

Contrast (1F0 default for me): +8
Sub-Brightness (800 default for me): -20

Go into your user menu and turn the user Contrast to around 65, and the Brightness, more importantly, to 64. The rest of the settings you can tune at your leisure to whatever you want.

The main effect of this tweak, clearly, will be that the light output from the panel is noticeably improved. I've always wished this panel had a way to pump up the light output, and this is definitely the closest I've come to realizing this. I've tested this, much like you militantmille, using AVCHD on my PS3, and it actually may have IMPROVED details in bright areas of the picture over the default HDMI.

If you do try it, and find any issues besides the obvious resolution downgrade, please let me know.

FYI, brightness should always be set with a black clipping pattern to the lowest setting that allows digital 17 to remain flashing (barely flashing to be exact). Sub-brightness can be used to do this as well, but don't use both sub-brightness and user menu brightness together. If you use sub-brightness, leave user brightness at the factory default (whatever it is when you press reset in picture menu). If you use user brightness, leave sub-brightness at the factory default (800). Modifying both is pointless and unnecessary. Also, note that all user menu settings are at factory defaults while in the service menu even though they revert back to where you set them when you re-enter the user menu. On Samsungs, the user menu settings remain at factory defaults upon re-entering the user menu.

BTW, it's okay to modify contrast in the service menu while keeping it at +100 in the user menu to increase light output. However, this doesn't work with HDMI for whatever reason like you mentioned.

I actually tuned the Sub-Brightness down since I found that tuning the user menu brightness, to offset the service menu Contrast, would cause me to lose detail in dark areas of the picture.

However, when I use sort of a Sub-Brightness/user menu brightness combo, I can come to a point where I'm not losing details in blacks, or whites really for that matter, and the line before "Reference Black" on AVCHD is barely visible. You don't think that Sub-Brightness and user menu brightness affect the picture of the panel in different ways?
