    Has anyone found a way to correct vertical bow with this family of sets?
    The service menu has pin/barrel/trap corrections. None of these can fix a slight bow on the verticals. Even parrallogram alignment is missing.

    It seems all Panasonics are missing propper geometry settings. I find on mine that if I correct the trap on one side, the other gets worse - meaning the need for a parrallelogram alignment option.

    Do you know what all the optons on the service menu do? There is a thread here that explains it but what I could really do with is a proper 'how to set-up the geometry of your tv' guide - just a general overview such as where to start and in what order to make adjustments.

    Look up the sticky about service manuals/menu. Somebody has a DK1 on there.

    I prefer to do it in this order:-
    horizontal center
    vertical center
    vertical height
    width (to set correct aspect ratio)
    trap (whole and corners)
    pin/barral (whole and edge)

    I can't do others with my pl1 otherwise I would have including them.

    You will see that vertical center changes cause trap misaligment. Theres no point in sorting out trap and then moving the image vertically.

    You need some sort of test disk to do this. I use lucasarts THX optimiser becuase it's free with some DVD's and I have it. I'm not saying it's anywhere near as good as the specialists disk such as Avia.


    You may find that the bad distortions at the extreme left and right can't be corrected. That's why most sets overscan.
