Check the set value of each
IC. Are the voltage values as
follows?
DIGITAL PCB
BN21A - 6pin
: Hi(3.3V)
BN21A - 7pin
: Hi(3.3V)
BN21A - 9pin
: Lo(0V)
Is the power supply voltage
being output correctly?
V+5V : C5107 : + side
V-5V : C5109 : - side
Is a signal being output from
the video amplifier?
CVBS : J5003
The circuit between IC511
and JK511 are faulty.
•Check the IC511 power supply volt
