Check the settings of each IC.
Are the following voltages set?
DIGITAL PCB
[N1039 : 12 pin] : Hi (3.3 V)
[N1039 : 13 pin] : Hi (3.3 V)
[N1039 : 14 pin] : Lo (0 V)
Is the power voltage being output cor-
rectly?
V+5V : [C5029 : + side]
V-5V : [C5031 : - side]
Is a signal being output from the video
amplier?
CVBS : [JACK5000 : C_out]
• Check the operation again.
• Check the [U5001] power voltage and check the soldering of
the surrounding circuits.
• The pattern between [U5001 and JACK5000] is faulty.
Extend the DIGITAL PCB using the jig.
