This has me stumped/agravated. I have a N64 which I got as a gift from my mom. She bought it second hand. I figured she was thinking about getting it for me and I told her to be sure to get the cable that had the RCA ends on it (it had an RF adapter with it already). Anyway, it worked fine until just a day or two ago. It worked that morning, then that night as I sat down to play it, I got no sound. I tried different games, but no luck. I have checked all of my connections and they are all secure. Has anyone had this happen to them? Does anyone have any suggestions on how to fix it? Thanks.
