My NES system has started making a pretty loud humming noise in the background during game play through the speakers. Even when the select game screen is on for Mario and Duckhunt it makes a loud humming. Any ideas on what might be the issue?

Could it be some type of setting on your speakers? are we talking speakers on a TV? or like surround sound? Could be something wierd on your Amp..

It is through a TV and the TV sound it's self in not the issue nor is it the rf adapter. I Hooked up the nes both through the RF and the A/V and got the same results. A humming sound during all game play.

I was going to blame the RF adapter, but I guess I can't do that...

Are there any other electronic deVices in close proximity, or even running on the same POWer breaker? the NES could just be more sensitive to "unclean" POWer.
