I have tested all of the speaker connections, tested the receiver from every input, and despite the fact that it turns on and 'appears' to function properly, there is no sound being emitted from the speakers. Any suggestions?
Common to 95% of all audio equiptment is a "Protectiion" feature which turns off the speakers when the electronics or the speakers are in an adverse state, You have only one thing you can do at this point, and that is to check the speaker wiring to see it is not SHORTED, and check the speakers to verify they are all working properly. Other than that, any other cause for the receiver to be in protection is internal and would require technical intervention. Repairs of this nature may run in the area of $75 ~ $150 or more. If you find that your receiver does need service, my advice based on age and development since yours was built would be to replace as technology has superceeded this receiver at a far lower cost than what you paid for this one. I advise you in this manner based on 38 years of audio and video service and I always want the owner to leave the transaction or service smiling, I hope this helps you.
Receiver "appears" to be in PROTECTION! This is NOT a customer repair if (and probably is) the receiver is in protection. Generally under these conditions, the unit will require parts replacement and depending on the extent of the damage, may cost as much as $150 or more. Strong consideration my be given to replacement of the receiver as new units are getting more and more "affordable". Sorry to levy this information on ya' but I'm advising you based on 38 years of servicing audio and video and I am trying to pursuade you to get "more bang for your buck" and leave you smiling in the end.

I'm thinking you have an open shield ground on the RCA input side. Connecting speaker inputs possibly restores the ground. Try connecting the high level inputs then disconnect the remote end of the cables (floating the grounds).
Then get out an ohmmeter and find that open circuitor or bad solder joint between RCA ground and real ground in the speaker's amplifier. Or.... if speaker ground kills the hum and you want to use RCA Line Level input to the sub, just connect one minus speaker output on your source amp to one minus on the sub's amp.
If by white noise do you mean the test tone generated by the receiver? If so, this is actually pink noise and it is internally generated by the receiver. I would make sure either in the menu or on the remote that you haven't accidently turned off the surrounds and double check the wiring to the surrounds. Good luck.
assuming same issue does not happen if you connect a headphone to your receiver - can you check your speakers' connections - it should be straight not crossed for each and in case speakers are properly connected to your receiver - can you test the audio/sound with internal test audio rather than connected device (ie player) - if this is ok and there is no sound/audio volume settings on connected device - change the input the device connected and test again.
I bought my AV-DV75 from Best Buy about 10 years ago and it still works. However it did stop working a while back. I don't know why. I alsmost threw it away. But I unplugged it for a couple of days, then plugged it back up and it came back on. It is still working. Maybe that will work for you.
my center speaker quit working recently. If you decide to sell your AIWA speakers will you please email me?
If all others had been fine before this problem arose, and you are sure that you haven't changed anything in your amplifier's channel selection menus, the problem might be deeper to solve! Try these out;
1-If the amplifier has a test menu to check out all channels plugged in, activate it. You must be able to get sound, which is like rustle, from each speaker.
2- Check your plugs, cables etc. be sure that there isn't any short circuit
3- Grab your amplifier's remote control and find the "channel selection menu" that allows you to increase and decrease volume levels for each speaker independently.
