    I have one I am trying to fix, the unit just clicks on then off... no
    front flourecescent display. All the fuses that I find are good, no
    shorted outputs that I can find.

    any suggestions from anyone that may have seen this before would be
    greatly appreciated....

    thanks for your time

  2. Try looking for a DC offset on any of the amp channels. Look to see if the
    output of each of the voltage regulators comes up before it shuts down. Look
    for the -30v line for the display - it could be your culprit.
    Sometimes it helps to connect a double - male AC cord to the switched
    outlet. MUST be the same polarity as the main power cord, which shouldn't be
    a problem. This may help troubleshoot other voltages regardless of shutdown
    It's likely you'll need a service manual before all this is through. Too bad
    because Aiwa's manuals are difficult to read / follow.
