Troubleshooting

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

Case

Cause/Remedy

The power
doesn’t come on

Is the power cord connected and plugged in
correctly? (p. 17)

The button
doesn’t work

Is Panel Lock activated? (p. 98)

Hold down the One Touch [

] button and

press the [Count/Marker] button to turn off the
Panel Lock function.

Nothing appears
on screen

The HPi-7S uses a liquid-crystal screen, so text may
not be displayed when the ambient temperature is
below freezing.

Is the music rest (screen) connection cable
connected correctly? (p. 16)

Is Panel Lock activated?(p. 98)
While Panel Lock is on, the screen display and the
indicators for all buttons are turned off.

Vertical lines
appear in the
screen/Color is
“washed out” at
the edges of the
screen

These occur due to the nature of a liquid crystal
display, and do not indicate a malfunction. They
can be minimized by adjusting the brightness of
the screen (p. 20).

Depressing a
pedal has no
effect, or the
pedal effect
doesn’t stop

Is the pedal connected correctly?
Make sure the pedal cord extending from the stand
is securely connected to the pedal jack on the
bottom of the unit (p. 16).

Has a different function been assigned to the
pedal?
See “Changing the Pedal Functions (Pedal)”
(p. 91).

Normal pedal operation is automatically enabled

when the One Touch [

] button is pressed

(p. 50).

Is the HPi-7S set to Twin Piano?
The pedal functions are changed automatically
when the Twin Piano function is on (p. 34).

The pedal rattles

Adjust the adjuster underneath the pedal so that
the pedal presses firmly against the floor surface
(p. 29).

The volume level
of the instrument
connected to
Input jacks is too
low

Could you be using a connection cable that
contains a resistor?
If you use a connecting cable that contains a built-
in resistor, the volume of the device connected to
the Input connector may be very low. In such
cases, please use a connecting cable that does not
contain a resistor (such as one from the Roland
PCS series).

Unable to read
from/write to
USB memory

Are you using (optional) Roland memory?
Reliable performance cannot be guaranteed if you
use non-Roland memory products.

Low hum coming
from external
device

Do you have different external devices plugged
into different power outlets?
When connecting external devices, always draw
power from the same outlet.

Performance
begins suddenly

The HPi-7S can be set so that the demo begins
playing automatically after the instrument has
remained idle for five to ten minutes.
Switch this setting (Auto Start) to “Off.”
Refer to “Setting the Demo (Auto Demo)” (p. 93).

Can’t select a tone

Press the [

] button several times to return to the

notation screen (p. 26), and then select a tone.

Is the volume level of the HPi-7S (p. 18) or
connected device turned all the way down?

Are headphones plugged in?
Has a plug remained connected to the Phones
jack? (p. 18)
When headphones or plugs are connected, the
keyboard’s speaker stops playing.

Could the “Balance” setting be set all the way
toward “Accomp” or “Keyboard”? (p. 61)

produced by playing the keyboard. Set Local
Control to On(p. 108).

Not all played
notes are
sounded

The maximum number of notes that the HPi-7S can
play simultaneously is 128. Frequent use of the
damper pedal when playing along with a song
may result in performance data with too many
notes, causing some notes to drop out.

The sound is strange

keyboard is
played

Is the HPi-7S in Dual performance? (p. 56)

When the HPi-7S is connected to an external

Thru feature is Off.
