Troubleshooting Troubleshooting If you hear no sound or a strange sound, first check the items described below and take appropriate action. You may be able to solve the problem by resetting the instrument to the factory settings (page 26). (Make sure to back up any important data to an external device first.) If the problem persists, consult your Yamaha dealer. ■ No sound comes from the speakers. • Are all four Control sliders set to appropriate levels (other than zero or minimum)? • Has the Local Control switch been set to off? If this is set to off, the internal tone generator will not sound. [UTILITY] → [F5] MIDI → [SF2] SWITCH → Local Ctrl (page 209) • Have you turned on the power of this instrument and all connected external equipment? • Have you made all the appropriate level settings-including the Master Volume on this instrument and the volume settings on any connected external equipment? • Is the Foot Controller pressed down (when it is connected to the FOOT CONTROLLER jack)? • Are you using an external MIDI controller and are the MIDI volume and/or MIDI expression settings too low? • Is this instrument properly connected to related external equipment (e.g., amplifier or speaker) via audio cables? • Are the effect and filter settings appropriate? If you are using the filter, try changing the cutoff setting. Some cutoff settings may mute the sound entirely.
