Keyboard Plays Wrong Chords

When I press certain chords on the keyboard, the instrument plays different chords. This happens only with certain chords and it happens intermittently. For example, I play a C major chord and the keyboard place a Cm7 chord. I play a G major chord, but the 740 sounds an F major chord. This happens only when the auto accompaniment is turned on.
