I think there is no shematics ..

or ..maybe there is but not for public :(

oh, that would be a pity.
is there no B & O technician who has ever repaired these boxes and has a copy of the schematics?

there is ..but if you know electronic ..go step by step..it can be repaired in component level.

I'm searching for an error in tweeter connection, the tweeter is ok, but I hear no sound (except the bass)

so no soud from tweeter ..zerro..zilch ?

are you 100% that tweeter is ok ?

if so ..check mosfets and resistrors ..ect..

I'm not 100% sure that the tweeter is ok,

have another tweeter (4 ohms) connected, it comes out no sound.

When I short the tweeter I hear the woofer.

I am not sure that tweeter 4 ohm is ok.  if it is same as geleraly most of B&O..than is 6 to 7 ohm.

What do you mean short...hope you are not shorten + and -  on tweeter cable.

I'm afraid the original tweeter has already done that, it has only about 1 ohm resistance (short circuit!).
Anyway, with this tweeter the bass woofer is active,
only high notes do not come from the tweeter
