DMW-FL28PP / DMW-FL28E 6 SERVICE HINT Malfunction content: Not oscillated. Symptom: 1. Not oscillated when the power switch is ON. 2. Oscillated when shorting both terminal of CUT1, charging voltage is up to 150 - 250 V and then shorting. 3. Normal charging is performed by shorting CUT1 but flash repeatedly comes to above symptom. Cause: Service point: Remarks: 4. Also comes to above symptom after flashed properly. T1 is rare shorting and disconnection of CUT1. Replace T1 and CUT1.
