Remove the CN-K, measure the voltages at K1(230V), K2(14.5V), K4(-15.6V) and
CN-P P3(80.2V),P6(8.5V) on the SW/HV PWB (PWE-571)
NG
OK
Check H and V sync input.
NG
OK
Judge peculiar noise of HV generated at power SW or static electricity.
NG
OK
Measure the voltage at IC7F1 3 pin on the CRT PWB (PWE-567C).
NG
OK
Measure the voltage at TP-G2 on the CRT PWB (PWE-567C). Normally,
screen voltage is 700
