OK
Check the voltage at the CNPU (pin3 and pin4)on the VIDEO PWB.
Confirm that the voltage varies at each direction of the monitor and
its variable range should be between +1.5volt and +3.5volt.
OK
Check the voltage at the CNCL pin14 or TP-TMP on the VIDEO PWB.
Confirm the output voltage from approx. 100mV to 500mV
(ex:250mV at 25 )
OK
* When power switch on, Check the voltage of C4P1's both ends increase
After a few seconds, the voltage continue to increase without saturation.
(See Graph 5-8-1)
* Be sure to use voltage meter which has input impedance more than 10M
OK
