Things You'll Need
Instructions
Check the controller connection. Make sure the serial cable running from the controller is inserted completely into the connection port. If not, you will be unable to control your video game.
Eject the video game cartridge and spray compressed air into its connection port. Perform the same task with the cartridge slot on your FC Twin device. Dust is often a problem with cartridge based systems, so spraying the compressed air into the hardware helps prevent the dust buildup.
Check the input on your television. Make sure the correct input is selected to view the video game. Typically the FC Twin hooks up to the TV via either RCA or coaxial cable connection.
Insert a different video game into the cartridge slot. It is possible the video game cartridge is just too damaged to play. If the newly inserted video game now works correctly you know the issue is with the original video came cartridge.
