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. 88) 
Turn the power off, then back on.
 
Nothing 
appears on 
screen
 
The HPi-6 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. 17)
Is Panel Lock activated?
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. 18).
 
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. 17).
Has a different function been assigned to the 
pedal? 
See “Changing the Pedal Functions (Pedal)” 
(p. 82). 
Normal pedal operation is automatically 
enabled when the One Touch [Piano] button is 
pressed (p. 44).
Is the HPi-6 set to Twin Piano?
The pedal functions are changed automatically 
when the Twin Piano function is on (p. 32).
 
The pedal 
rattles
 
Adjust the adjuster underneath the pedal so 
that the pedal presses firmly against the floor 
surface (p. 27).
 
The volume 
level of the 
instrument 
connected to 
Input jacks is 
too low
 
Could you be using a connection cable that 
contains a resistor? 
Use a connection cable that does not contain a 
resistor.
 
Unable to read 
from/write to 
external 
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-6 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. 
88).
 
Can’t select a 
tone
 
Press the [
] button several times to return to 
 
No sound is heard
 
No sound is 
heard
 
Is the volume level of the HPi-6 (p. 18) or 
connected device turned all the way down?
Are headphones plugged in?
Has a plug remained connected to the Phones 
jack? (p. 19)
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. 55)
 
No sound from 
left-hand 
section of 
keyboard
 
Is V-LINK switched on? (p. 88)
When V-LINK is switched on, the twelve keys 
at the left end of the keyboard are used to 
control images, and no sounds are played with 
these keys.
 
No sound is 
heard (when a 
MIDI instrument 
is connected)
 
Are the MIDI cables connected correctly? 
(p. 97)
Does the MIDI channel match the connected 
instrument? (p. 98)
 
No sound is 
heard when the 
keyboard is 
played
 
Has Local Control been set to “Off”?
When Local Control is set to Off, no sound is 
produced by playing the keyboard, Set Local 
Control to On (p. 98).
 
Not all played 
notes are 
sounded
 
The maximum number of notes that the HPi-6 
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
 
Sounds are 
heard twice 
(doubled) when 
the keyboard is 
played
 
When the HPi-6 is connected to an external 
sequencer, set the Local Control to off (p. 98). 
Alternatively, the sequencer could be set so its 
Soft Thru feature is Off.
 
The tuning or 
pitch of the 
keyboard or 
song is off
 
Is the setting for the “Master Tuning” correct? 
(p. 81)
