There may be a number or reasons why the hum comes back and goes. The cartridge may not be securely plugged in or connected. The phono jacks may be loose. Other wires may not be securely connected. The unit is defective. There are always a certain number of units in any production run which are lemons. Perhaps there are problems with your amp circuitry or the connection to the amp or a bad circuit within the unit that causes intermittent humming. Perhaps there is a bare wire touching another wire or a loose wire other than the ones mentioned above. If you like the unit enough take it to a local audio repair tech and have her/him check the unit out on pro gear. There may be a number or reasons why the hum comes back and goes.

have you tried what Wm Mcbride suggested? I am considering buying the AT-PL 120.I have a Technics SL 23. Without connecting the ground wire will give the HUM!

I should have mentioned that you should always switch the amplifier off to prevent "explosive pops" when connecting or disconnecting things.

Just because this unit didn't come with a ground wire dose not mean you can't make one. Find a metal area on the frame of the unit-there should be a screw there somewhere to connect a wire and connect the other end to a metal area on the receiver-there should be a screw there also. I really hope this works for you-good luck.

Sorry to be so long, but while the problem seemed to clear up, it suddenly developed the hum again. I have a Technics receiver with a phono output, so I have the turntable set to Phone Off. This worked until today, when it suddenly developed a hum, and when I tried to reconnect the wires the white wire produced a pronounced hum and the red wire produced an explosive pop. I played it this afternoon without incident, and have played it for hundreds of hours since last summer, but today the hum came back with a vengeance.

i actually use another rca line input and use the pre amp from my turntable with an in line booster (between turntable and 5000) and it works much better than the phono input on the 5000. i was getting a humming noise using phono input. your setup might be different though. either way my vinyl sounds awesome now!

I have Onkyo TX-SR805 7.1. I also have this hum. I've tries everything under the sun and nothing gets rid of it. I've isolated it to the receiver in a pain staking process of elimination. If anyone has a fix, I would be interested. I have to have to return it, because otherwise it is awesome. That hum is really beginning to get to my ear drums.

I noticed it too. When the device is connected via the instrument connection the floating ground will cancel any noise. One must remember, this isn't a professional piece of equipment with layers and layers of MOSFETS, JFETS AND TRANSISTORS To switch on and of the signal. So, even though there is no signal, it's amplifying the hum from the AC transformer as well. In common terms, it needs to be connected to a device to cancel the noise. Even in the ground, or lift phase.

Mine is in a home stereo setup. Quietest turntable I've ever had. I had issues with the same cartridge because of the high output. Changed them out and no more hum.

I recorded from the turntable and I got the music, but I also got ambient sounds from the room where I was recording, ie I ran some water in the sink at the other side of the room and that sound recorded, too, and basically ruined the recording of my music. I'm going to call them in the morning. I also have a problem with the level of the volume. The recording was at a very low volume and there is no control on the turntable that will up the volume. I a, also using a Mac.

I think I only ever noticed degradation with patch cords like in the 10 foot range. And really long ones can sometimes pick up radio wave interference and/or give you a hum, hiss, or slight buzzing sound. One of these cords plugged into a phone for example, then patched into a larger amplifier, and you'd never know that music was coming from the phone! Sounds as full and rich as it's recorded!

You're experiencing ground loop hum. Try using batteries only. If you still here loud hums, send it in for repair.

Yeh, I bought mine 10/15/08 and had the same problem.It turned out to be a ground loop between my Receiver and my Samsung TV.I put a two-prong "cheater" on the Samsung power plug and that fixed it.Not the best way, but the hum is gone.

Lucy,I found the source of my hum. I have Direct TV HD. I found that going into the menu settings/Audio/Sound Effects and turning that option off, I was able to rid myself of the annoying hum. The option has something to do with keeping the audio settings from channel to channel, while it is changing you hear dead air except for the hum. Nice and quit now. Love this receiver!Larry

My best guess would be cables that are hook up to your amp or phono amp need a ground isolator on one of your hook ups.My computer hook up to my receiver would hum,Radio Shack had a ground isolator.Stop the hum.Double check your wiring on your cartridge also red,green, blue, white,wires must be correct.Good Luck.

Sounds like a loose connection, but I think more information is needed to diagnose the problem. Is there a troubleshooting guide in the owners manual? Does the tone arm return to the home position when it stops playing or does the turntable just stop?

The hum might be due to a ground loop. This problem often happens when you interconnect devices via RF/audio/video/etc. cable that are plugged into electrical circuits with different grounds. To troubleshoot this, try disconnecting FM antenna, input and/or output cables from your receiver. Assuming that you have any kind of cable connecting the TV to the receiver, also try removing the RF cable from the TV. Cable TV hookups are reputed to be common causes for ground loops. If the hum goes away with a particular cable removed, search online for a ground loop eliminator device for that type of connection. An inexpensive audio ground loop eliminator is available at RadioShack stores; higher-end audio ground loop eliminators are available online. Cable TV ground loop eliminators are available from online sources. For further information, search the Web for the words "ground loop". Hope this helps! Dave

Sounds like you have a ground issue somewhere, I haven't experienced any hum or distortion

Thanks very much to those who offered suggestions. Everything was fine with the wiring. A phone call to a Sony tech resolved the problem, which was found to be my selection of HDMI Passthrough to "ON". As such, the receiver remained partially powered in Standby and resulted in the hum. Re-selecting HDMI Passthrough to "OFF" cured the problem.
