Unplug receiver from AC outlet, unplug speaker wires and replug receiver in AC outlet and push power button. If receiver still does not power up, this means receiver got problem in output amplifier section and system control chip will not permit power supply to power up just to avoid further damage in amp section.

If you have electronics repair experience of receiver, let me know to guide you with more technical info.

Hi and welcome to FixYa,

Initially, your description "unit tries to turn on but then shuts off. Red light is on, but no power to the receiver" is significant. It is indicative that the unit initially powers on, perform a built-in diagnostics, senses a fault, powers itself off to prevent further damage to its components/circuitry.

A few ideas you could try:

  • check the speaker/speaker wires using a continuity tester/ohmmeter. Reading should be between 4 ~ 8 ohms;
  • unplug the unit from the mains for an extended period of time. The idea is to dissipate capacitor stored electrical charge and hopefully revert the unit back to factory defaults;
  • perform the power-enter buttons to reset.
Good luck and Thank you for using FixYa.

    The unit would then require opening, perform voltage measurements,determine faulty component and subsequent part(s) replacement. Further, a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron would be required. It would be to your added advantage access to a service manual or at the very least a schematic diagram with voltage readings.Should you be uncomfortable performing a DIY (do-it-yourself), perhaps your best bet would then be to seek the services of a qualified professional.

    Cheers.

That means that the unit is on protect mode, this happens when there is a short or a faulty component inside.


Try first leaving the unit unplugged from everything for one hour, if it stays on protection when you plug it back, thaen that means that there is an internal fault.

My aiwa av-x200 click right off when I turn it on, Im thinking it is a blown fuse or something, anybody fixed any receiver with this problem?


The unit is going into protection mode. There is a fault detected in either the power supply or an overload on the output circuitry. Remove all connections to the amp (ie speakers, dvd players etc etc) Turn the unit on. If it still turns off the problem is internal and should be looked at by a qualified technician.

Does not power up.


chuck05,

You might try to find a reset button on the back of the unit. Also, the Aiwa website may have a "support" staff that can see if they have an archived manual or tell you which buttons to push. Also, check to see if the unit has a fuse in back. Finally, check a website called audio.manualsonline.com . It's a free deal where people exchange manuals and information.

Sudden failure to power up


I've had this happen a number of times with my receiver. This trick from the Troubleshooting guide in the owner's manual usually does the trick: To reset If an unusual condition in the display window or malfunction occurs, reset the unit as follows. 1 Press the POWER button to turn off the power. 2 Press the POWER button while pressing the ENTER button. Everything stored in memory after purchase is canceled. If the power cannot be turned off in step 1 because of a malfunction, reset by disconnecting the AC cord and carry out step 2.
