You most likely need to clean the cartridge slot. If the N64 can't read the cartridge, it will not display any picture or sound. I usually clean my older cartridge-based Nintendo systems by dipping a qtip in %90 isopropyl alcohol (rubbing alcohol) and then running the qtip along the connector on any N64 game cartridge. Then repeatedly insert and remove the cartridge from the slot on the system. This will clean off any dust or dirt that has built up inside the slot over the years.
