    The auto can be turned off under picture setting, changing contrast to normal. Contrast now no longer changes depending on picture content etc... :D

    Nope, completely false information. I have only spotted the problem while using normal so go figure that one out.

    Sorry, greyhorse, I don't understand how you set Contrast to 'Normal'. You can set Viewing Mode to Normal (I've still got it on Cinema, of course). Is that what you mean?

    And I don't see how a sensor at the front would change the brightness of the picture caused by a bright object appearing in the picture...

    And I still can't see these sodding lines, either... :)

    I was experiencing these occasional brief moments of brightness changes, too.

    I´m NOT using the auto-setting.

    Here´s what solves the problem (I`m 99% sure after watching 2 shows without noticing it again)

    DISABLE the Colour Management and it *should* be gone!

    I´m using "Cinema" setting with Colour Management set to off and so far it hasn´t occured again. (to be certain 100% I`ll have to watch some more movies, though) :clap:

    i also disable the power save feature, you'll notice an improved noticable increase in contrast! :D and like KOrn colour management is off ! god we pay for all these extra features but prefer the picture when there turned off! :rotfl:

    I would understand if it only happend with that Automatic-setting enabled.

    But it happens with all picture modes! So it´s definately NOT the automatic contrast sensor.

    Like i said before, turning off "Colour Management" seems to help.

    I don't have this plasma and have never used one so i can't comment on what you have seen.I totally believe you have a real problem and hope there is a quick answer to this issue.Good luck. :smashin:
    What i do find poor is the manuals discription and explanation of the CATS feature. :thumbsdow as i say on the page it says to look at (page 13) it doesn't tell you anything about CATS!

    Thanks for all the help! Let's hope than that with the color management set to "off" the auto constrast feature will also be permanently :clap: off.
    Altough it seems that the light sensor on the front of this PDP will always adjust the brightness :eek: , not the contrast... :rolleyes:

    Yeah, but that will be dictated by the amount of light in the room, not on the screen. This seems reasonably sensible - there's a huge difference watching a screen in darkness and in bright sunlight. I don't know how this version works, but I can't believe it would lead to sudden changes in screen brightness.

    I´ve got some new information:

    Panasonic Customer Support told me that disabling P-NR and MPG-NR could help eliminating the issue.

    In another note, after disabling Colour Management, the effect seems to be nearly gone. (at least it´s not as noticable as before)
