FLOW CHART NO.6
P-ON+15V is not outputted.
Is the supply voltage 44V fed to the cathode of D013?
Check D013 and their periphery, and replace
P3(PW/SW ASSEMBLY) if defective.
Check for load circuit short-circuiting or leak, and
replace P1(AV ASSEMBLY) if defective.
FLOW CHART NO.8
AL+12V is not outputted.
Is the supply voltage 12V fed to the cathode of D014?
Check D014 and their periphery, and replace
P3(PW/SW ASSEMBLY) if defective.
Check for load circuit short-circuiting or leak, and
replace P1(AV ASSEMBLY) if defective.
FLOW CHART NO.7
TU+30V is not outputted.
Is 44V voltage supplied to emitter of Q1511?
Refer to "FLOW CHART NO.6"<P-ON+15V is not
outputted>.
Is the "H" pulse (approximately 5V) inputted to
the base of Q1512?
Check the P-ON-H siganal line, and replace
P1(AV ASSEMBLY) if defective.
Check Q1511, Q1512 and their periphery, and
replace P1(AV ASSEMBLY) if defective.
