E
No
Are there
signals(approx. 0.5
Vp-p) in all
lines?
Yes
Check the IC101.
If IC101 is failure, replace IC101.
Step 3-1: Power Supply
[Video converter]
V+5A
Is the voltage

Check the R1001.
If R1001 is failure, replace R1001.
Check the R417.
If R417 is failure, replace R417.
Check the L403.
If L403 is failure, replace L403.
Check the L404.
If L404 is failure, replace L404.
Check the L701.
If L701 is failure, replace L701.
Check the L702.
If L702 is failure, replace L702.
Check the IC902 and D901.
If IC902 or D901 is failure,
replace IC902 or D901.
Check the L401.
If L401 is failure, replace L401.
Check the L402.
If L402 is failure, replace L402.
Step 3-2: Video Input
CN1002 (Pin 1)
Is there a
composite
signal?
No
CVBS IN
Yes
a
Diagnose the MAIN CONTROL
Assy or COMPOSITE Assy.
CN1002 (Pin 5)
Is there a
Y signal?
No
SY IN
Yes
a
Diagnose the MAIN CONTROL
Assy or S-VIDEO Assy.
CN1002 (Pin 7)
Is there a
C signal?
No
SC IN
Yes
a
Diagnose the MAIN CONTROL
Assy or S-VIDEO Assy.
Note:
Check is unnecessary because component
input does not convert it.
