Aiwa AV-D58 Receiver - Answered Questions & Fixed issues

That sounds like the main amp is failing. I suspect the unit will have one IC as the power amp, which will need replacing. You can have a look inside to see if you can see something like this: If you do. Make a note of the number on it, it might say something like STK563. Then put your number into Google and it will give you a clue to how much it will cost and if it is obtainable. You can then either fix it yourself if you have the skills or take it to the repair shop.

Receivers often have the ability to switch off the subwoofer channel. Especial if it wasn't connected before. If it has the ability to do a speaker test or set up try that. If it bypasses the subwoofer that will confirm the channel is not on.

Try to RESET the receiver, here is a link to your operating manual. Go to page 23 Aiwa AV D58 User Manual

When turning it on hold the enter key at the same time to reset the machine back to the factory settings...worked for me when I had that exact problem.

Any powered sub will work.

Assuming the physical volume control on the receiver still works I would say the remote's volume control is faulty.

Read this procedure to possibly fix the remote:

They also sell replacement remotes.

Zoom in on the picture of the original remote provided on the site (or look at your own) and get the actual remote model number.

or check eBay: search for "(model of the device or the remote) remotes", check the 'include description' box. Usually cheaper than the vendors.

Have someone check your house wiring to see if the live and neutral are reversed.

Beyond that - you may have some leaky capacitors. If you're tech savvy, open up the unit and see if any of the electrolytic capacitors are bulging at the top or leaking at the bottom, and if so, unsolder and replace them. This is actually the most likely issue.

Please be more specific.

I'dont have solution but I have the same problem.
Do you find solution ?

Can we simplify this a bit. It sounds like you're making more of the task than it requires.

When you say "can't hook up my previous subwoofer", do you mean physically impossible or that you can't get it to work after it's attached? This receiver requires a self-powered subwoofer.

Do you have the manual? The receiver is its own tester. I have no idea what kind of tester you're using.

Get it here. http://www.retrevo.com/support/Aiwa-AV-D58-Receivers-manual/id/1076dj789/t/2/ and give it read. Pages 6 and 19 discuss the subwoofer.

The Aiwa only provides a pre-output for the sub amplifier.

did you ever get an answer?? i'm having the same issue

I had the same problem, there was a closure by the Q335 transistor in the sorround amplifier. You have to abolish this. Br., csdombi

Hi, I've found the problem. There was a closure in the Sorround Amlifier, and the protect circuit stopped the whole receiver. Br., csdombi

Required Aiwa remote is available in Part Store for $39
Thanks.

Is the sub out turned off in the setup menu of the reciever?

Perhaps I misunderstand the question.

Depends on the Sub. Most powered subs will go into standby mode in the prolonged absence of a signal. Then they wake up when you play something.

Or are you saying you need to Enable the Sub, as in setup? Remote probably required for anything like that.

Without knowing more about the subwoofer (powered, passive, what kind(s) of input it takes, I have to take a wild guess. Most powered subwoofers use the old standard RCA cable. I there are two jacks on the sub for Left and Right input you just get an adapter to make the cable plug into two jacks.

I had that, Mine was bad solder joints on the relay. Its on the power supply pcb attached to the transformer. All good now

try to check the transistor and resistor
