Yamaha Dgx-640 - Unusual Noises With Some Triads Immediately Below Middle C

The specific problem is centered in the octave immediately below middle C and is acute with the following triads; D-F-A; E-G-B and F-A-C. There are intermittent hints of a problem with a few other triads. A technician addressed this problem a few weeks ago and the instrument was only returned to use one week ago.
