That's an inherent problem with RF. If the TV has composite AV inputs, I recommend using that instead. The Genesis doesn't have the best composite video signal, but the audio will improve greatly and you shouldn't have a snowy picture.

If RF is a must, there's a few things you could try. For starters, don't chain multiple RF adapters together. If it's set to channel 3, trying setting it to channel 4.

You know what that metal shielding is for, right? it's to prevent electro-magnetic interference (within the confines of FCC regulations). If the metal shielding is compromised, the Genesis itself is subject to interference from other devices, and it is capable of causing interference with other devices. That includes your TV set. So what can you do about this?

The answer is threefold.
  • First, you need to use composite cables instead of rf cable. If you only do one thing, this is the most important in terms of picture quality. Game Trog has photos and a complete description on this page.
  • Second, you need to get the Genesis as far as you reasonably can from other electronic devices (including the TV set) so as to diminish the effects of RF interference.
  • Third, you could consider replacing the rf shielding inside your Genesis. It's not so hard to do if you have tin snips and a drill. Be careful not to cut yourself on sharp metal. Make sure you've had a tetanus shot some time in the last ten years.

If the metal shield only has minor surface rust then I wouldn't think it's compromised.

Good point, Ziggy. Without seeing it for myself, I have no direct way of gauging the condition of the rf shielding. I just know that parker is getting a very fuzzy picture.

In either case, the composite cable is the first order of business.

I wouldn't blame the rust just yet. Do you get the snow without the 32X connected?

Can you try and take a picture of it and post it here?
