vice Switch is pressed. This switch is located on the
deflection PWB. By removing the front speaker grill,
the Service Technician has access to this switch.
CONV. OUT:
The Convergence output block represents the two (2)
Convergence output IC’s. These two IC’s contain the
amplifiers for the Red, Green and Blue convergence
outputs.
HDT T752:
Represents the Deflection output transformer. By
separating the Deflection circuit from the High Volt-
age, any distortions that would be generated by fluc-
tuations within the High Voltage won’t be visible
within deflection.
DYNAMIC FOCUS OUT:
This circuit amplifies the parabolic signals provided
by the Deflection circuit and I702 on the Sub Deflec-
tion PWB and impresses these wave forms onto the
static DC voltage use for focus. This keeps the beam
as sharp or focused as possible in the corners of the
screen.
HIGH VOLTAGE REGULATION DETECTOR:
This circuit monitors a feed back voltage produced
from the High Voltage Flyback transformer and routes
an output signal to two circuits.
1.) A sample voltage is sent to the Horizontal Driver
IC for regulation of the High Voltage and;
2.) If the High Voltage climbs too high, a shut down
signal is produced to shut down the power supply until
a repair can be made.
FOCUS PACK:
The focus pack receives the Focus voltage and the
High Voltage and distributes them to the CRT’s.
FBT TH01:
Is the main Flyback Transformer producing High
Voltage.
