With just the speakers hooked up to receiver, no antennas or input devices, volume set at minimum, system makes loud popping noises. Also, whenever I press any control button on the front it makes a loud clicking sound through the speakers a minimum volume.

The connections should tell you that. If it has sockets for two sets of speakers and two inputs for the sound then it will be a stereo model.
What you can do to test the system is to disconnect the speaker connections to the receiver and use a 1.5 volt battery connected across each speaker cable end. For only a brief time. At the other end you should hear the speaker pop. I suspect you will need two people to do this. Make certain the volume control unit is on full.
If you don't hear the sound of the pop the cable is either faulty or disconnected somewhere.
erm.... this is a strange one, the popping very loud sounds is the amplifiers turning on and lookinf for the input, so its possible the input method has been altered from original settings i would try fixing this first, im sorry i cant be any more help or any help at all to be honest lol, worst case scenario put your daughter in front of it and let her play away again. good luck : )
I had this happen to my unit shortly after I purchased it. When I turned the receiver on there was a loud pop through the speakers, the red light on the front started blinking and the unit failed to produce sound.
A tack worked its way through one of the speaker wires, causing a short. I replaced the wire and unplugged the receiver for an hour. It's worked well for the past two years since this issue.
If you haven't done so already, check all of your speaker wires and plugs on the receiver and the speakers. You may have a damaged wire or metal-on-metal contact somewhere. Try these steps:
1. Unplug the unit and disconnect all wires and connections. Let the unit sit for an hour.
2. Check all cords for damage or crossed connections.
3. Reconnect the power cord and set the volume to minimum. Turn the receiver on. If it stays on, shut it off, unplug it and reconnect everything, taking care to ensure that speaker wires and/or plugs don't make contact.
4. Plug the receiver in, set the volume to minimum (it should already have this setting after step 3) and turn it on.
It sounds like there is a short somewhere in either the wiring or the receiver. This caused the popping noise and activated the receiver's protection circuit. If it's a damaged wire or plugs or wires making contact, you can reset the unit with the directions above, replace or separate the wires and all should work. If the issue is within the unit, you'll have to contact Onkyo directly.
How loud? Just noticeable if you focus or could it be buried by music? I've heard of and had noise from other electical devices in room like a light dimmer. Try headphones. Make sure your signal and speaker wires aren't running near power cords or sources of high current or magnetic fields like TV's and other speakers.
jd40, Sounds like a grounding issue. The first two places to look into is the powered subwoofer and antenna. During your last test, did you leave the FM antenna and subwoofer connected? Many times the hum is directly related to the antenna and/or the subwoofer and to how they are grounded; creating a ground loop through the receivers ground on the outlet. If the antenna is grounded to the dwellings wiring, hum is inevitable and sometime you can get a ground loop hum from how or how & where the subwoofer is grounded. Try taking them completely out of the loop.
Also try taking it further back to the basics, start with the receiver plugged into a known good grounded outlet with no surge or line conditioner in the loop and nothing connected to the receiver, nothing. Use one speaker and different wire to test each speaker output while in tuner and any other mode but phono. With no signal, you will either get nothing (no hum or static) or just static in the tuner mode. No hum is a good sign. Some systems will mute the speakers if no signal is connected to eliminate the static from being produced through the speakers but a ground loop hum will most likely still be produced even in mute. If you get a hum when nothing is connected to the receiver, try looking into getting a better grounded outlet, even maybe to a different dwelling.
just repaired my se 501 poor solder conections on blue rleays by speaker jacks,also blown center speaker seems there are 2 in it one blew and so did cpacitor running now just hooked up one in center speaker sonds great also stay at 8 ohms setting
you may be using an equalizer? try to pop-up the volume with all tone controls in flat mode. see if it still cuts off. if this is the first time youencounter this then something must be wroing with either your speakers or your amp. unless your ventilation is not good enoughg, you can also try placing a blower on top of your unit to cool it down
Were they ever loud? If they weren't (which is my guess - judging by the picture) is that they are low wattage which essentially means that they are not intended to be loud. They are most likely to be used as a small compact, low-noise speaker for a smal MP3 player where high (club-vloume) wattage/volume is needed. If they used to be loud check the volume control on your laptop and check each and every setting that there is. One stupid little setting could be a big difference. Audio Properties in the control pannel could be helpful but don't mess with those settings in the control pannel unless you are almost positive as to what they are and what they do. You could cause yourself a bigger problem. Remember that most laptop speaker outputs are actually for headphones and are not intended to go super-high as they are designed for headphones and not to hurt ears at high volumes. Hope this helps. If not try checking back with me. Best of luck. Bonne chance!
