Does anybody know anything about HP Oscilloscopes disassembling?

In our lab we have HP 54615 B (500MHz) Oscilloscope with damaged BNC connectors.
The problem is that I can't disassemble connectors block, which is somehow placed ontop of mainboard.
I don't know, is it soldered ontop of the board or just placed on the "comb" jacks (I don't know, how they are called in English). On the back of the mainboard I can see series of pins, like [::::::::::][::::::::::::] [::::::::::::], but is it connection socket or direct soldering, that is the problem.

Does anybody know, where to find service manual on the similar Oscilloscope, or how to disassemble it?

Thanks!
I've already found it, but thanks anyway.

For the future searches(for archive):
That block is named "Attenuator module" (or something alike)
It is placed on 3 connectors. It must be removed with the extreme care since module parts of the connectors are placed on fragile ceramics HF boards (3 boards for each channel).

The problem was in EXTREMELY STUPID design of input BNC jacks.
Seems, like they are assembled "on the knees" in a garage... I would recommend to kill the case designer on the sight Sad
The best choice I found was to place BNC connectors on the "liquid threadlock" in the socket.
