Best examining the power supply saw the burnt plate where the diode ZD260 zenner. The Zenner diode was replaced, but I think they put the wrong diode. The monitor is not binding, nor does the led. This diode Zenner is protective. Already replaced the electrolytic capacitors of the source. Does the logic board is damaged? The source code of the card is as follows: P / N: 3BS0086018GP FSP045-2PI01 |

put the diode ZD260 P6KE10A and resistor R223 of 10K . The diode ZD260 (P6KE10A) began to heat up enough. |

placed zenner diodes 5 12v / 1A in parallel and also replaces the TL431 regulator by a new one. By feeding the monitor, returned to normal operation. |
