Yamaha Receiver issue

[Mosin]

Unit is a Yamaha RX-V471, its about 6 months old.

Lately I've been hearing actual FM radio through all speakers at a very, very low volume. Regardless of what source it's on. I've tried unhooking FM antenna, moving wires away from each other, and trying diff speaker wires.

Every source is ran by HDMI cables if that makes a diff.

I know at concerts it happens through some amps on stage, the general fix is to hit the 'ground lift' button, are all the devices your running through the receiver plugged into the same power supply? Im not really sure how one would track down the cause of this. Does it only happen if you have something playing, or does it also happen if you just turn in the speakers? try unplugging your devices one by one it could be something in one of the decives that is picking it up? (not sure if it happens with all inputs or not)

Try the same method with the speakers and see what happens

but remember, NO HOT PATCHING! my mate recently fucked his yammy receiver by hot patching things. so take the time to turn it off and back on again

Yes, all of my devices are plugged into the same, grounded power supply. The receiver has an FM tuner built in in case you didn't catch that. It happens on any HDMI setting, any volume, and through all 5 speakers. Same if i'm listening to music from iPod plugged into receiver via USB.

Does it get louder when you turn up your volume on the receiver? If not then its just interference and you cant really do much to get around that a majority of the time. What id recommend trying would be to disconnect all inputs on the receiver and disconnect all but one speaker and see if you still hear the radio on the speaker. If you dont take the speaker and hook it up to the next channel and go down the line that way (start with the left, right, center, left rear, right rear, etc) just dont connect all of the speakers at once. Id make the speaker runs as short as possible for this test as the more wire you have the more it is able to pick up on the frequency the radio station is transmitting at and interfere with your receiver. I had this with my Sony home theater i have now and it turned out that it was just one of my rca's that wasnt well shielded and was running along the floor next to the ac power wire that was picking up on the station.

Give that a try and let me know how it goes. If this doesnt help then try to take the receiver elsewhere in the house with one speaker and test it there. Normally you cant stop this when it happens, only try to minimize its impact.
