Troubleshooting
PROBLEM
POSSIBLE CAUSE/SOLUTION
When using a mobile phone, noise 
is produced.
Using a mobile phone in close proximity to the Tyros3 may produce 
interference. To prevent this, turn off the mobile phone or use it further 
away from the Tyros3.
The Main display does not appear 
even when turning the power on.
This may occur if a hard disk or USB storage device has been installed 
to the Tyros3. Installation of some hard disk units/USB storage devices 
may result a long interval between turning the power on and appear-
ance of the Main display.
In the LCD display, there are some 
black points (unlit) or white points 
(always lit).
These are the result of defective pixels and occasionally occur in TFT-
LCDs; they do not indicate a problem in operation.
The overall volume is too low, or no 
sound is heard.
• The master volume may be set too low. Set it to an appropriate level 
with the [MASTER VOLUME] dial.
• If volume control is assigned to the foot controller or [ASSIGN] 
slider, set it to an appropriate level. 
• All keyboard parts are set to off. Use the PART ON/OFF [RIGHT 
1]/[RIGHT 2]/[RIGHT 3]/[LEFT] button to turn it on (page 38).
• Make sure the desired channel is set to on in the CHANNEL display 
• The volume of individual parts may be set to low. Raise the volume 
• Headphones are connected, disabling the speaker output. Unplug the 
headphones.
• A plug is inserted in the LOOP SEND jacks. Unplug the LOOP 
SEND jacks.
• Is the footswitch connected to the appropriate jack?
• The [FADE IN/OUT] button is on, muting the sound. Press the 
[FADE IN/OUT] button to turn the function off.
• Has a Voice been selected from the Expansion Voice Bank? The 
Expansion Voice Bank is a bank for saving Voices that you have cre-
ated or obtained via Internet, etc., and is empty by default.
The sound is distorted or noisy.
• The volume may be turned up too high. Make sure all relevant vol-
ume settings are appropriate.
• This may be caused by the effects. Try cancelling all unnecessary 
effects, especially distortion-type effects.
• Some filter resonance settings in the Voice Set display can result in 
distorted sound. Adjust these settings if necessary.
• Is the gain of the Low band set too high in the EQ Page of the Mix-
The keyboard volume is lower than 
the Style/Song playback volume.
• The volume of the keyboard parts may be set too low. Raise the vol-
• The [ASSIGN] slider may be set to a low level. (By default, keyboard 
volume is assigned to the [ASSIGN] slider.) Set it to an appropriate 
level.
A strange “flanging” or “doubling” 
sound occurs.
• Are the RIGHT 1 and RIGHT 2 parts set to “ON,” and are both 
parts set to play the same Voice?
• If you are routing the MIDI OUT on the Tyros3 to a sequencer and 
back to the MIDI IN, you may need to set Local Control setting to 
“off ” in the SYSTEM Page of the MIDI display (page 110).
The sound is slightly different each 
time the keys are played.
