NES bad picture quality + no sound

[Pizzapiezero]

I purchased an NES via Ebay about a month ago. I managed to get it to work, but the picture quality is quite bad and there is no sound. When the sound eventually does come around, it comes in the form of a loud buzzing noise. What should I do? Here's a video showcasing my problems. https://youtu.be/GH9FiZyLM5M

I may be way off, but based on the patterns of interference it seems like the audio is crossing into the video stream. When I messed up some cables on my Genesis a similar thing happened.

How did you solve it? And how can I?

Looks like a broken RF adapter that's beyond its life. I've seen this on the NES and older stuff like the fairchild channel F which is from the mid 70s. Try getting a new RF from radio shack or something, or get a RCA cable and pop that in. Even if the RCA you have is stereo, it still will at least let you see and hear if it's a busted system or busted RF cable.

Would this help?

No that would be useless as it's basically an extension cord of sorts.

You need this - http://www.ebay.com/itm/6FT-AV-Audio...item1c5546dd12 (MONO Audio/Video cable)

Yes, if you're in Europe that would be a direct cable to connect the RF output to European TVs. I would listen to Bratwurst first as he knows what he's talking about.
