What to do if my Yamaha YPG635MM has no sound?
First, ensure that nothing is connected to the PHONES/OUTPUT jack on the rear panel. Also, if the FILE CONTROL display is showing, press the [EXIT] button to return to the MAIN display. You may also want to check the Local Control on/off.
Why does the right hand side of my Yamaha Electronic Keyboard not make sound?
If you are using the Dictionary function, the keys in the right hand area are used only for entering the chord root and type, and will not produce a typical sound.
Why is the sustain pedal reversed on my Yamaha Electronic Keyboard?
The polarity of the footswitch may be reversed. Ensure that the footswitch plug is properly connected to the SUSTAIN jack before turning on the power.
Why does my Yamaha YPG635MM Electronic Keyboard make noise when I use my mobile phone?

How to fix a Yamaha YPG635MM Electronic Keyboard style that doesn't sound right?

Why does my Yamaha Electronic Keyboard cut off some sounds?
The instrument is polyphonic up to a maximum of 64 notes. If the Dual voice or Split voice is being used and a style or song is playing back at the same time, some notes/sounds may be omitted (or 'stolen') from the accompaniment or song.
