Standby Flashing

When the standby light is blinking, the receiver is indicating that the amplifier is in the protected mode. The common fix for a malfunctioning receiver, resetting the microprocessor, will not clear this fault, it is a hardware defect. The protection circuit is triggered when the receiver detects a DC offset condition, indicating internal damage to one of the amp circuits. As a result, the protection circuit powers the unit down and prevents the relays from engaging to prevent damage to the speakers or other amp circuits.

This is a serious internal hardware defect that would require repairs to correct. It can be caused by age, manufacturing defect, or a power surge.

To be certain, you can test that this is not a short in a connected speaker/component by disconnecting everything from the receiver except power (all speakers and source devices). Then try to turn it back on in tuner (am/fm) mode. If it will start up then, you had a short or a bad speaker. If it shuts down and the problem continues, this confirms the dc offset condition and the receiver would need to be repaired/replaced.

Unfortunately, this type of repair is not really practical. It can be done, but the costs of parts and labor will be in the $200-300 range, which is more than the receiver is currently worth, and would go a long way toward a replacement model. If you'd like help finding a local shop for repairs let me know your zip code, or I can recommend a replacement model if you prefer.

Thanks
