CAUSE ACTION Crack on the PWB due to transport damage. If there is no 300VDC across C708, then check the continuity between L703 and the cathode of D704. If this is open circuit, fit a wire link between the two points as indicated in the diagram below.

ACTION 1. 2. 3. 4. Add a new diode ( 1N4148 ) from the emitter of Q509 to the cathode of D513, cathode of diode to the emitter of Q509. Replace R534 with a 390R. Solder a fuse ( QFS-J1023CEZZ ) in series with L607. Solder a fuse ( QFS-J1023CEZZ ) in series with L608. Refer to the diagrams given below.
