Tries to start and is inoperative with irregular power supply up and down on the multimeter | The ceramic capacitor c719 shorted out, killing the diode 709, and as a precaution I replaced the electrol/high capacitors, the fly, trz h and vertical ci. Even though it was 14 years old, it looked new. | Berto | |
