7. TROUBLESHOOTING
SYMPTOM
T.V. screen does
not come on.
REMEDY
Make sure your television set is turned on and the power
cord is plugged in.
No game playfield
image on screen
(but screen is lit).
Game playfield is
on screen but the
picture is rolling
or the screen has
bars or lines on it.
Picture quality is
good, but sound
buzzes or is
distorted.
I:
Make sure the power switch on the control deck is turned on.
Make sure that the AC adapter is plugged into a 110/120 volt
wall outlet and that the AC adapter output jack is plugged
into the Control Deck.
Make sure that the Control Deck and the antenna wire are
connected to the RF switch properly and that the RF switch
is connected to the TV (refer to “Connecting the NES Con-
trol Deck to Your TV Set").
Make sure the game pak is inserted into the control deck
correctly (refer to the game pak insertion section in your
NES Instruction Manual). Also, try pressing the reset switch
on your Control Deck or try turning the power switch off
and then turning it on again.
Make sure that the Channel 3/Channel 4 switch on the
Control Deck is set to Channel 3 and that the TV is set to
Channel 3.
Adjust the vertical or horizontal hold controls on your tele-
vision until picture becomes steady.
If there is interference on Channel 3, change the Channel 3/
Channel 4 switch on your Control Deck to Channel 4 and set
your TV to Channel 4.
A particularly strong television station may be broadcasting
on Channel 3 or 4 (or on cable TV) in your area and causing
interference. Try disconnecting the antenna wire from the
RF switch. (You will have to reconnect it again for regular
television viewing.)
Make sure that you are not trying to use both the RF switch
and the audio/video cables. Only one or the other is required
(see page 3).

it off and use the manual fine-tuning contro! to get a better
picture, (If your TV loses its color when the AFC is off, turn
it back on.)

Channel 4 switch on your control deck to Channel 4 and set
your TV to Channel 4.
