Question about Aiwa AV-D57 Receiver
All I can get out of my receiver now is a clicking sound whenever I push the power button. I tried pushing the Power and Enter buttons at the same time hoping to achieve a resetting of the factory settings, but it just tries to keep powering itself up about every 2 seconds to no avail. Anyone have any ideas if I will ever be able to use my receiver again?
Hello degaff, This is what I would do to try to determine the problem: 1. Disconnect everything from the receiver. The only thing connected should be the power cord. Make sure the power cord is disconnected from power for at least 30 minutes in order to reset the internal electronic software. 2. Then, power it up - still nothing else connected. If it powers up normally and "looks" like it is going to work, then turn it off and connect only the right speaker to its amplifier and try again. If it still looks normal, then turn it off and connect the DVD or CD player and run some music through that speaker. If it still looks normal, then shut it off and connect the left speaker, etc... In other words go one-by-one in checking it out. 3. If it does NOT power up after step ONE, then there is a problem internally. If it powers up only to shut down again, there is still a hardware problem internally. The usual cause is shorted output transistors. And the normal cause of shorted outputs is a short on the speaker line, a short inside one of the speakers or overdriving the amplifier for too long a period of time. If the outputs need replaced, then it will cost an arm and a leg to get them repaired, and you are better off replacing the unit. The clicking sound, by the way, is the power relay which turns the power transformer on. And if there are faults in the amp, speakers or wiring, the protection circuit shuts the relay off; that is the clicking sound you hear. Please let us know how this works, and if we can help you any further. Best regards, nightdiver
