(Is normally used for adjustment)
The Compensation line must always be set to On, but if a faulty geometry in the
picture occurs it can be set to Off, to determine if the fault is in the earth field
compensation circuit or in the deflection circuits.

In the TV service setup menu it is only the Tuner system and AFC fields that have
to be used. The rest of the fields are for factory usage, and the values in them
must not be changed.
Tuner system:
The digital value in the field stands for the CTV system for which the applicable IF
is intended.
If the Tuner & IF PCB is replaced to permit reception of a different CTV system, the
digital value has to be changed.
The digital values for the various systems are the following:
B/G =
1
L/L’ =
2
M
=
4
D/K =
8
I
= 16
The digital value for system combinations is obtained by adding the applicable
digits.
The digital values for the IF variants in BeoVision Avant 32 DVD are the following:
B/G
=

B/G/L/L’
=
