Out Of Cg-Specification - NEC MultiSync FP1350 Service Manual

16. Out of Cg-specification

Adjust the static and the dynamic convergence with OSD control.
NG
Check the voltage at the feedback resistor(vertical S-cg : R8J3, horizontal S-cg : R8H3).
Confirm the variable range of the voltage at the feedback resistor should be approximately
-2.3volt --- +2.3volt within the control range of the static convergence control.
OK
CRT ITC FAILURE.
NG
Confirm the output voltage range of the IC510 (pin 7: H.S-cg, pin 1 : V.S-cg) on the OSC
PWB should be approximately +1.2volt --- +2.1volt within the control range of the static
convergence control.
OK
IC8H1,IC8J1 failure or its associated circuit failure.
NG
Confirm the output voltage range of the IC501 (pin 61: H.S-cg, pin 60 : V.S-cg) on the OSC
PWB should be approximately +1.2volt --- +2.1volt within the control range of the static
convergence control.
OK
IC501 failure or its associated circuit failure.
NG
IC501 failure or its associated circuit failure.
