1
Loose connection
/Defective SW
Related point
Check if there is loose connection on the
signal line from the PA
N
EL CPU (IC501)
up to the SW.
If there is no loose connection and if the signal does
not become "L" when the SW is pressed, that SW is
defective.

If the symptom persists after the above
corrections,
Check a mounting state of PA
N
EL CPU(IC501).
If the mounting is OK, the PA
N
EL CPU may be
defective.
The signals from other keys are analog and connected to multiple switches.

Related point
Check if there is loose connection on the
signal line from the PA
N
EL CPU (IC501)
up to the SW.
If the SWs connected to the signal line function
properly and if the connections are properly made,
the SWs may be defective.

when the rotary selector is turned or pressed.
If the signals are not normal, check the connections of
the signal lines. If the connections are properly made,
the encoder (S527) may be defective. Replace it.

Check if there is loose connection on the
signal line from the PA

If the connections of signal line are improper,
resolder it.

Check the TEMPO signal level.
If the voltage of the TEMPO signal line (IC501-pin 97)
does not change between 5.0
V
and 0
V
, the tempo
slider may be defective.

Check that the control signal for the LED
is output from the PA
N
EL CPU (IC501).
If no signal is output, check a mounting state of
PA
N

of LED
P
N
LB Assy
Check that the forward voltage (2.2 - 2.7

)
is present at both ends of the LED.
If the forward voltage is not present, then the LED
itself is defective.
