couple of months ago i picked one up off craigslist, and, like any NES nowadays, it needed a new pin connector. It wasn't that bad at first, but has gotten worse, to the point where I can't play it anymore. I'm assuming id do it the same way you'd fix a regular NES, however I've heard that some old tvs hold an electric charge, and i dont want to be electrocuted. Is there any way I should go about changing it differently from how i normally would?
