Power Supply On and Off Circuit Explanation:

The DP-4X Chassis utilizes 5 relays.

RY101

AC Supply to the Signal Power Supply Relay

RY102

AC Supply to the Deflection Power Supply Relay

RY103

DC Supply to the Audio Output Relay

RY104

AC Supply to all AC Relays Relay

RY105

DC (SW +5.7V) Supply to the Low Voltage Regulators Relay

(4)

RY104

AC Supply to all AC Relays Relay

Starting with

RY104

because this Relay supplies AC to

RY101

and

RY102

which in turn

supplies AC to the Bridge Rectifiers for the Signal and Deflection Power Supplies.
When The Stand By Power Supply develops the

SBY +5V

, (

see previous page

) this DC

voltage is delivered to the primary windings of

RY104

and to the relay driver Q105 for

RY104

. This turns on the relay and supplies AC to the above mentioned circuits.

(1)

RY101

AC Supply to the Signal Power Supply Relay

When the set is turned on, the

POWER SIG

command is supplied from pin

of the Mi-

croprocessor

I004

. (This high also turns on the Power LED on the front of the set). This

high is sent to

Q018

and

Q021

then to the

PPS1

connector pin

labeled

POWER 1

From here this high goes to the Deflection PWB through

R120

R110

D109

to the Base

Q101

goes high and the transistor turns on. This action supplies a ground return for the

coil inside

RY101

and the relay turns on supplying AC to the Signal Power Supply recti-

fier

DS201

and the Signal Power Supply begins to operate.

(2)

RY102

AC Supply to the Deflection Power Supply Relay

When the set is turned on, the

POWER DEF

command is supplied from pin

of the Mi-

croprocessor

I004

. (This high also turns on the Power LED on the front of the set). This

high is sent to

Q023

and

Q024

then to the

PPS1

connector pin

labeled

POWER 3

From here this high goes to the Deflection PWB through

R125

R122

D110

to the Base

Q102

. The base goes high and the transistor turns on. This action supplies a ground re-

turn for the coil inside

RY102

and the relay turns on supplying AC to the connector

PC2

Then to the Deflection Power Supply rectifier

DP01

and the Deflection Power Supply be-

gins to operate.

(3)

RY103

DC Supply to the Audio Output Relay

When the set is turned on, the

POWER DM

command is supplied from pin

of the Mi-

croprocessor

I004

. This high is sent to

Q028

and

Q029

then to the

PPS1

connector pin

labeled

POWER 2

. From here this high goes to the Deflection PWB through

R124

to the

Base of

Q103

. The Base goes high and the transistor turns on. This action supplies a

ground return for the coil inside

RY103

and the relay turns on supplying Audio B+ to the

connector

PPS1

pins

and

Then to the Signal PWB and

on to the Audio Output IC
