I really hope it kicked in.
Do you know a way to check if there is any LNB power?
If there is no load i.e no LNB connected will the LNB power be there so 
one can check it?

is there a big different between rev 1.6 and 2.1
LNB power supply unit?

I did a source.conf with different sources each having diseqc
with move east, move west, HALT, Set Posns ASTRA, Store ASTRA, etc.

Exampel for Move East

:source.conf
S0.5E   DiSEqC Drive East

:diseqc.conf
S0.5E  11700 V  9750 t W15 [E0 31 68 40] W15 t
S0.5E  99999 V 10600 t W15 [E0 31 68 40] W15 T
S0.5E  11700 H  9750 t W15 [E0 31 68 40] W15 t
S0.5E  99999 H 10600 t W15 [E0 31 68 40] W15 T

:channels.conf
Drive East:11686:v:S0.5E:22000:160:83:0:0:30200:0:0:0

Will this really work?

This can be the problem, It was snowing and an unique snowflake
may have landed in the F connectors when connecting them.

I don't have one neither my friends with diseqc 1.2.
Any one live in nacka - sweden who would like to help me out :o) hehe
