Answer to: My Nintendo 64 turns on, but there's no picture.No picture could mean the game is not loading up. In that case, it's best to clean the contacts of the game cartridge. I use isopropyl alcohol. If it's not the game, make sure to clean the AV plug or buy a replacement cable. Note that the N64 does not support RGB SCART. N64 units are pretty tough. I bought one from a stand drenched in rain water and still managed to get it working. Hopefully, you can get your system working. Good luck!
