Exam the voltage of “ AGC ” on A101 without antenna

Check R119, R213, R101,C104,A101,N204

Test the voltage on pin 14,17,25,29, 49 of N204

YES

＜

YES

Check C311, C306, 302, C209, C204, C238,
C230

Test the voltage on pin 44 and pin36 of N204

Check N902, N204

Check N902, N204, C311, C306, 302,
C209, C204, C238, C230

Observe if there is snow-noise-wave disturbance on the CRT via using “Signal-input way ” by touching pin 43 and pin 42 of N204

Test if there is the sync signal on the pin 9 of N204

Check C212, A101, N204

Observe if there is snow-noise-wave disturbance on the CRT via using “ Signal-input way ” by touching pin 24 of N204

Check L901, R946, VD902, V902

Observe if these is snow-noise-wave disturbance on the CRT via using “ Signal-input way ” by touching pin 50, pin51, pin of N204

Check R226,R237,R238,V601,V611,V621 ,N204
