MONITOR OUT(CVBS) output NG
2. Analog video
Check the set value of each IC. Are
the voltage values as follows?
SW2 :IC5401-10 pin :3.3V : OK
SW5 :IC5401-2 pin : 3.3V : OK
Is a signal being output from
the video amplifier?
Output V : R5439
The circuit around IC5401 is faulty.
Check the cable between this
unit and the MONITOR or the
MONITOR unit.
Check the soldering of JK5401
on the VIDEO PCB.
Is a signal being input to the video
amplifier?
(SAT/CBL Case of function)
Vin3 : IC5401-7 pin
Power circuit is faulty.
CPU is faulty.

Is the power supply voltage
being output correctly?
+5HV : C5431 : + side
-5HV : C5428 : - side
Check the pattern from JK5401 to
IC5401, and check the cable be-
tween this unit and the PLAYER or
the PLAYER unit.
