Beneath the MOTIF's control panel is an array of tactile switches
soldered to PC Boards.
When you push a button on the panel, it pushes on the
stem of one of these tact switches.
When a switch's electrical contacts start to wear out, you have to
press harder on
the plastic button to make the switch
conduct.
Eventually the tact switch won't work at all. The
plastic button, which is a separate part, can also break if you press
too hard on it.
This repair story shows you how to remove and replace worn-out tactile
switches in a Yamaha MOTIF.
There are 3 Switch PCBs.
The Right board holds the data dial and all the tact switches right of the
display. Pull off the dial knob before
removing the Right PCB.
The Left PCB holds all the switches left of the
display plus 5 sliders and 4 rotary
knobs. Pull off the slider and rotary knobs before removing the
PCB.
The Center PCB holds the switches for the buttons under the
display.
Before removing the Switch PCBs, refer to the
MOTIF6-7 Disassembly story. It shows you how to remove the computer cage and keyboard assembly, which
must come out before
the Switch PCBs do.
First, test each button many times on several days. A switch that
misses even one push should be changed while its board is removed since this job takes time.
