Problem
Game display is on the TV screen, but the picture is fuzzy, has no colour or
has snow on it. (For RF Switch connections only.)
Solution(s)
Make sure that the Control Deck and antenna or cable are properly connected to the
F Switch and that the RF Switch is connected to the TV (see page 6).
Adjust the fine tuning and contrast controls on your TV to receive the clearest picture
possible.
If your TV has an automatic fine tuning control (AFC), turn it OFF and use the manual
fine tuning dial to adjust the picture. If turning OFF the AFC causes your TV to display
in only black and white, then leave the AFC ON.
If the Control Deck is too close to the TV, the Control Deck may cause some
interference. Try moving the Control Deck farther from the TV.
A particularly strong TV station (or Pay TV) may be broadcasting in your area and
causing interference. Try disconnecting the antenna wire from the F Switch. (You will
have to reconnect it again for regular television viewing.) Or, use a video switch (not
provided.
Make sure the RF Output of the RF Switch (marked OUT), is connected to the VHF
input on you TV.
Problem
Picture quality is good, but there is no sound.
Solution(s)
Make sure the TV volume is turned up to an adequate level.
The sound in some Game Paks begins only after START is pressed.
If using an RF Switch connection to your TV, adjust the fine tuning control until the
sound is clear
If using an AV connection, check the audio (red and white) connections of the
audio/video cables (see page 5).

Try pushing the RESET button. If there is no improvement, slide the Control Deck Power
Switch OFF, then remove the Game Pak and reload it. Slide the Power Switch back to
the ON position and push the RESET button.
Problem
The controller does not work.
Solution(s)
Make sure the Power Switch on the Control Deck is in the OFF position before
plugging in the controller.

you turn the Power Switch of the Control Deck to the ON position.
Make sure the controller plug is firmly plugged into socket number one (on the left side
of the Control Deck).
