Troubleshooting

If you think there’s a problem, read this first.

Symptom Cause/Action Page

Power does not turn on

Is the AC adaptor connected correctly? p. 14

Nothing appears in the

screen

Since the VIMA uses a liquid crystal screen, it may happen that no text or graphics

appear in the screen if the temperature is below zero degrees Celsius (32 degrees

Fahrenheit).

–

The screen shows vertical

lines / Color is washed-out

at the edge of the screen

These are due to the nature of a liquid crystal screen, and are not malfunctions.

You can adjust the screen brightness to minimize these artifacts. p. 16

Pedal does not work, or is

“stuck”

Is the pedal connected correctly?

Plug the cable firmly into the pedal connector.

p. 39

p. 40

Device connected to the input

jacks has insufficient volume

Could you be using a connection cable that contains a resistor?

Use a connection cable that does not contain a resistor. –

No sound

No sound

Could the VIMA’s volume or the volume of the connected equipment be turned

down? p. 15

Could headphones be connected?

Could there be a plug inserted in a headphone jack?

The speakers will not produce sound if headphones (or anything else) are

connected to the headphone jack.

p. 16

Could the [BALANCE] knob be set all the way toward “KEYBOARD” or “SONG”? p. 38

No sound (when a MIDI de-

vice is connected)

Are all devices powered on? p. 50

Are the MIDI cables connected correctly? p. 53

Do the MIDI channels of the VIMA and the connected device match? p. 57

Not all the notes you play

are sounded

The maximum simultaneous polyphony is 64 notes. If you are playing along with

a song and making heavy use of the damper pedal, the number of notes the VIMA

is attempting to produce may exceed the maximum polyphony, meaning that

some of the notes will drop out.
