Check on the circuit diagram if the
inoperable keys and LEDs use the same grid.
Is the same grid used?
No
Only the direct-input keys
are inoperable.
No
Are the rotary VRs directly
connected to and controlled by
the microcomputers?
No
Check if a normal waveform is input to the microcomputer, referring to
"e Jog rotation signal" in "10.46 WAVEFORMS."
If no problem is found, replace the microcomputer:
• Replace IC3601 in the MIXB Assy.

Check the corresponding grid, referring to
Grid control" in "10.46 WAVEFORMS." If no grid
waveform signal is output from the shift register
IC, check the communication line with the
microcomputer first, then check if the grid line is
short-circuited with GND, caused by a failure in
a key, LED, or the transistor for the drive. Also
Yes
check the connection of the grid line. If there is no
problem, replace the shift register IC:
• If the MIXER block is in failure
Replace IC3001 in the MIXB Assy.
• If the CDJ block is in failure
Replace IC4002 in the CDJB Assy.
• If the level meter LEDs do not light
Replace IC3501 in the LLED Assy.
See "No operation with keys (switches), No
operation with slide switches, No response
to pressing the rotary selector," or "The
LEDs do not light."
Check that current is conducted between the
terminals of the switch when it is pressed. If current
Yes
is not conducted, replace the switch. Check the line
between the switch and the microcomputer. If the
line is OK, replace the microcomputer to which the
switch is connected, as follows: MIXB Assy: IC3601.
Check the transistors on the line that is
connected to the microcomputer port and
waveforms and connections of the line. If no
problem is found, replace the microcomputer
(IC3601) in the MIXB Assy.
Check that the resistance value of the line that is
connected to ground and the microcomputer
changes in accordance with turning of the VR.
Yes
Check the connection line between the
microcomputer and the VR. If no problem is found,
replace the microcomputers to which the VR is
connected, as follows: MIXB Assy: IC3601.
Check that the resistance values of the lines that
are connected to GND and a microcomputer
change in response to turning of the VR.
Check the connection lines between the analog
SW ICs and rotary selectors/VRs, referring to
"f A/D SW operations" in "10.46 WAVEFORMS."
If there is no problem, replace the analog SW IC to
which an inoperable rotary selector/VR is connected:
• If the MIXER block is in failure
Replace IC3201 and IC3202 in the MIXB Assy.
• If the CDJ block is in failure
Replace IC4001 in the CDJB Assy.
