RY105
DC (SW +5.7V) Supply to the Low Voltage Regulators Relay
When the set is turned on, the
POWER DM
command is supplied from pin
91
of the
Microprocessor
I004
. This high is sent to
Q028
and
Q029
then to the
PPS1
connector
pin
12
. From here this high goes to the Deflection PWB through
R126
to the Base of
Q104
. The Base goes high and the transistor turns on. This action supplies a ground
return for the coil inside
RY105
and the relay turns on supplying
SW 5.7V
to the con-
nector
PPS1
pins
25
,
26
and
27
.
Then to the Signal PWB and on to
the following
Low
Voltage
Regulators and ICs.
