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. 15)
The button doesn’t
work
Is the panel locked? (p. 140)
Turn the power off, then back on.
Nothing appears
on screen
The KR105 uses a liquid-crystal screen, so
text may not be displayed when the
ambient temperature is below freezing.
Vertical lines
appear in 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).
The touch screen
doesn’t respond
correctly
The positioning of the touch screen may
become displaced if some time has passed
since it was last used. Take a look at
“Calibrating the Touch Screen (Touch
Screen)” (p. 139) to correct the positioning.
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
connector on the rear of the unit (p. 15).
Has a different function been assigned to
the pedal?
See “Assigning Functions to Pedals and
Performance Pads (Pedal Setting/User
Functions)” (p. 126).
Normal pedal operation is automatically
enabled when the One Touch Program
[Piano] button is pressed (p. 16).
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.
926b
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.
Mic volume
changes
Adjusting the panel’s [Volume] knob may
cause the mic volume to change.
No sound is heard
No sound is heard
Is the volume level of the KR105 (p. 17) or
connected device turned all the way down?
Are headphones plugged in? (p. 17)
Has a plug remained connected to the
Phones jack?
When headphones or plugs are connected,
the keyboard’s speaker stops playing.
Has the Balance knob been moved all the
way to the right or left?
Has the volume been set to “0” using the
Part Balance? (p. 52)
Has the footage been adjusted so that all
frequency components aren’t sounded? (p.
15 in the Quick Start)
No sound is heard
Is the speaker cable connected and plugged
in correctly?
No sound from the left side is V-LINK
switched on? (p. 143)
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)
Have all devices been switched on?
Are the MIDI cables connected correctly?
(p. 144)
Does the MIDI channel match the
connected instrument? (p. 146)
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. 146).
Not all played
notes are sounded
The maximum number of notes can play
simultaneously is 64. Frequent use of the
damper pedal during automatic
accompaniment or 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
Is the KR105 in Layer play? (p. 25)
When the KR105 is connected to an external
sequencer, set it to the Local OFF mode
(p. 146). Alternatively, the sequencer could
be set so its Soft Thru feature is OFF.
