New Panasonic THX Certified 42PZ800U, 46PZ800U, and 50PZ800U Thread! - Page 260

1. Flip up control panel below screen on the set.
2. Using VOL- button on set, reduce VOL to 0 and release button.
3. Hold down VOL- button and hit INFO button on remote 3 times. You may have to do this more than once.
4. The Service Menu will be displayed at the upper left of the screen.
5. Press 2 on the remote once and you'll be at SRV-TOOL then hit OK on the remote.
6. Use the cursor keys to move the highlight to the blank space to the right of PTCT:00.00.00.00.00
7. Then press and hold the MUTE button on the remote for 3 seconds and the Time and Count will be displayed (Count is number of power ons).
8. To get out of the Service Menus, power off using the POWER but on the set.

Don't mess with any other settings in the Service Menu until you do some research as you can really screw up the picture.

So my dog hopped on my couch and my logitech harmony turned on the tv, and blu ray. It was sittin on the samsung blu-ray start screen for some number of hours not sure how many.

I am not sure if I simply have IR or Burn In any tips or tricks to clean this up?

I am running the scrolling bar right now and turned the pixel orbiter on force 4.

Any other ideas??

I believe you are doing what needs to be done to clean up on the screen. Is there still a visible logo when you turn off the TV. What you need to set is the auto shut off on the panny so it turns off if inactive after some time. Check the Bd player for a screen saver too.

No logo with the screen off just visible imprint of the home screen with the TV on a all black or all white screen.

Image is not visible with a normal picture on the screen.

I know i'm digging threads here and the TV is getting to be a few years old, but i though't i'd post the results of my own panel of what can be achieved with only the user-menu settings. Before i delve into the Service menu to try and get it spot on.
NOTE: my TV is a non-THX certified 46-PZ800A

Results are using an i1Display2
this has only been calibrated as beast as possible with the THX Disc and Blue filter glasses.

these are the results from the Normal Mode with Normal Colour Temp
Using HCFR and the HCFR Test Patterns (lucky i know a little French.) and using the Curtpalme Greyscale for dummies guide.
I have results for the Cinema mode, Colours track exactly the same, but with even lower gamma in the low end.

Contrast is only on 80 and it's pumping out 63.2FtL of peak brightness (217cd/m3) NOTE: (Comfortable Daytime setting, no adverse picture effects evident)
and a Black Level of 0.019FtL (0.07cd/m3)
Average Gamma of 2.15

Gamma not tracking too bad, but a little low in the low end (I assume due to the high level of peak brightness??)


Luminance levels track well


Colour Temp is a little cool, but looks a heap nicer than excessively warm

and we can see why it's a little cool, too much blue and not enough red


Most DeltaE's are all pretty consistent around 10-13 with a couple further out


so at least i have a place to start to at least get the greyscale colouring correct.

My DVD player does have it's own built in 10point gamma correction so once i have the greyscale right i can then look at getting the gamma spot on for my highPQ source.
for my DVR i have MP4 versions of the calibration images so can get that input as close as possible, but with a compromised gamma, however, the quality of the recordings are usually of lower quality and unknown origins, so they're compromised from the begining

I'm going to do a complete reset to see how bad it's out of the box presets actually are... horrid i assume

I'll be interested to see what effect getting the colours spot on has on the Gamma curve, maybe none?
but i'll experiment and see what becomes of it.
