   Hi

    

    When i turn on the equipment, with eveything connected, i can only
    hear the main transformer and the monitor´s inicial humming sound
    .The equipment does not proceed from this point. The LV PS fans
    don´t work and no readings can be obtained on the LV PS. The green
    leds on power control do not light up. On the HV PS the green
    led indicating power on doesn´t light up. If i unplug CN102 or CN30
    the LV fans start working and i can obtain all the voltage readings
    on LV PS as described in service manual,the green led on the HV PS
    turns on and the green leds on power control flash correctly.

    

    What could be the problem?

    

    Best regards

    

    Paulo

	Hi Chris First of all thank you very much for your support. I followed the diagram and came to the conclusion it was the HV board. I then exchanged it with another one which worked just fine. I also detected that the 220V AC was not supplied to the power supply connectors. Is there any thing i can do to repair the HV board besides substituting all the capacitors? Best regards Paulo

	Hello Paulo, I honestly do not know - we do not perform board level repair/troubleshooting. Regards, Chris
