I just purchased the Panasonic TC-32LX60 LCD for use during my 6 mile workouts each morning. I have attached the final calibration results, although I think I can drop the black level a bit and squeeze out some more contrast.

The set was easy to calibrate and I had no problem getting the grey scale to track well. The Panasonic service menu divides color and grey scale into different sections within the menu. Initially I calibrated the set in the cinema mode but the picture was washed out. The measured gamma was 1.6 in cinema. It was apparent that standard and vivid had a better gamma curve. These results are from calibration in the standard mode and the gamma is fine. Unfortunately manipulating the color points is not really possible. I wanted to shift green closer to it's theoretical optimum but Given the purpose of the set I didn't feel the need to try to get the color points closer.

I am impressed with HD picture on the set. It is vibrant with well saturate colors and has a much lower noise level than my panasonic industrial plasma. SD looks very good too. Black level is really my only issue but the contrast is adequate for me. Still to expensive though for a 32" at this performance level. Over the next year or two I hope the prices for these smaller lcd's drop by half and the performance doubles.

Bberns: Hi! What settings did you end up with both on Service Menu side and User Menu? Be curious to see how your SM settings compare to what we have been using to correct for the red push.

It sounds like your backlight setting might be a bit high still. Cinema mode looks very smooth here with BL down between -10 and -20. Above that it does look quite washed out. Certainly the Standard and Vivids are much more dramatic, but they also tend to crush the blacks if you are not careful.

Also, what is your environment like?

Cinema mode is useless as the gamma in that mode is less that 2.0. This set does not exhibit any red push. Look at my grey scale and color gaumet. Red is actually undersaturated on the gaumet and my grey scale is really close. Unclaibrated the color temp in warm was around 8000 and the color primaries were the same as they were after calibration. I use a GretagMacbeth Eyeone beamer, accucal and color facts software. What do you use?

This set is used in my basement, I watch it when I exercise. Its size is too small to be used in any home theater setting and its performance is at the margin of acceptability.

Wow, that is really unusual. Almost everyone with these Panny's (LX60/600) reports a bad red push initially. You're numbers do look like the red is a wee bit high. Sure folks don't look just a bit tanned???

As for Cinema mode, well it performs better here with the backlight turned down, but clearly the gamma is Much steeper on the other modes (maybe too steep on vivid). For dark room viewing the cinema mode does provide less contrasty but better shadow detailed images.

Wish I could afford the color tester and software, but am currently just using a borrowed optical comparator and DVE with color filters. As such I am afraid I can not provide numbers for you. Sorry.

I can tell you though that in HD my green is just a bit stronger than it ought to be, in SD just a bit weaker. And the warm color temp here is just a touch too warm, I have been trying to get sufficient time to go in and redo the color temps in Service Menu (toss the silly Vivid settings, shift the Normal temp settings into the Vivid slot and create a new set in between Normal and Warm). Seems like there are some interesting differences in our sets.

Oh, and just a quick reminder in case you did not know, these tv's have different sets of Service menu settings. For Pict-Adj there are separate HD and SD settings, and for White-Bal there are a set of settings for each Color temp. You probably knew that already, but just in case... :D

What are your user menu settings at?

just picked one of these up from my g/f and neither she nor I have any idea how to calibrate the video settings.

Kshep: Welcome!

First, I would recommend using a calibration disc of some sort
to provide the test patterns you need to set up your tv.

If you are an absolute beginner I would recommend the
ISF/Monster disc which will do the main part of the work
without getting too deep technically.

If you are technically inclined I would recommend one of the
following: Avia, DVE (Digital Video Essentials) or GetGray.
(Note: I have not personally used the last one myself, but
based upon the reports upon this forum it is an excellent
choice.)

The discs will not perfect your settings for every source,
but should provide you with a very good starting point.

Things to know specifically for this set:

There are different settings for each and every input
and each different mode.

The "AI Picture" option tries to dynamically adjust contrast,
but just ends up wildly changing the picture. Turn it OFF
for each possible setting.

The "Noise Reduction" option turns off an additional sharpening
routine, smoothing the picture and allowing proper control
of sharpness with the sharpness control. Turn it ON.

The modes not only give you different sets of controls, but
also give you modified gamma's for the picture. Vivid will give
you the most dramatic picture, but will have more of a tendency
to crush your shadow details. Cinema gives a great deal of
shadow detail and much more linear performance, but can
look somewhat washed out with certain material or situations.
Standard is in between the two, of course.

In addition to the Picture and Brightness controls, the Backlight
setting has a very strong effect on the deepness of the Black
Levels and the brightness of the whites achievable. You might
wish to have some settings for bright room (Backlight somewhere
around 0) and a different set of settings for dark room (Backlight
between -30 and -20).

This set generally will have a tendency to have a red push.
There is a fix, but it involves using the service menu's and
given your uncertainty I would not recommend messing
around there. It is possible in service mode to do "Bad Things"
to your set, so for now I would recommend you stick to
the basic fix, which is to turn the color control down on the
tv to remove the push.

Finally, there is a very active group of helpful folks in the
LCD/Plasma forum in the Thread about Panasonic LCD
LX60/LX600/LE60. Check in there and read all about
working with the set and how to get the most out of it.

If you need more help, feel free to contact me either here,
at the LCD forum or even by Personal Message.

Hello,

I have several questions regarding the service menu. I have a previous experience with service menus on my Sony CRT thanks to very good web sites, but with my Panny I don't know how to proceed...

I know the codes to get the service menu, but I don't know how to navigate, to change values or to save or cancel the settings. Could you help me on this?

I'd like to fix the following problem: It's impossible in my set, using the regular menus, to have blacks that are as deep as the black zones in 4/3 mode (even with brighness equal to zero!) Do you think it could be fixed with the service menu ? what parameter should be changed?

I own an european version of this set, do you think the settings in the first post applies to it? Currently, I think that the color are strange with dark scenes; while they are awesome with bright ones. I'd like to see if these settings fix the issue. Again, I don't know how to apply these settings

Thank you
