13.Surge Protector
a.) Measure voltage between blue and brown on
the connecter J
7
Normal :AC 207~264V
If normal proceed to b.
Faulty: Check if voltage on the fuse
terminal is AC207~264V
b.) Measure voltage between white and white on
the J
8
.
Normal: AC207~264V.
Faulty: replace surge protecter unit.
14.Transformer
Check for the transformer
a.) Measure the voltage between red and red on
the transmission connector (A
2
).
Normal: AC90~110V (12~21 Ω)
If normal proceed to b.
Faulty: Check if the voltage on fuse
terminals is AC90~110V.
b.) Measure the voltage of the connector (A) on
the PCB.
Normal: Between Brown and Grey AC
30~50V
Between Yellow and Grey AC 180~220V
If normal, proceed to
c
Faulty: Replace transformer.
c.) Measure voltage between Green and Green
of connector (D) on PCB.
Normal: AC 12~18V
If normal, proceed to 4.
Faulty: Replace transformer.
Note) The above transformer voltages are meas-
ured while the appliance is in standby mode -
not while it is operating.
