Check/repair/adjust

• Check that connector P6 (YPM) on the control 

circuit board is securely inserted and the Y-pulse 
motor is correctly wired.

• Refer to #1.1-2

• Refer to #1.1-8 [E.CI]
• Check that connector P25 (FAN-L) on the control 

circuit board is securely inserted.

• Check that the PROM of the control circuit board 

is securely inserted and its leads are not bend.

• Check that MN and MT of the PROM are matching 

those on the main PCB.

• If the PROM has no problem, check the 

connection between pin 3 in connector P18 
(PANEL) on the control circuit board and pin 5 in 
connector P5 (DRV) on the panel PCB.

• Check that the PER code is securely inserted (refer 

to #1.1-15).  If the error appears, replace the 
power PCB with a new one.

• Check that connector P2 (PER) of the power PCB 

and connector P20 (PER) on the main PCB are 
securely inserted.  Check there is no damage in 
wiring.

• Find a cause of noise.  (Refer to #1.1-2.)
• Replace the power PCB .  (Refer to #1.1-14.)

• Check whether the panel setting plate makes 

contact with a switch.

• Refer to #1-7

• Pull out the programmer.  If a switch is activated, 

the programmer is defective.

• Check the connections and pins between 

connector P1 on the panel PCB and the FDD, and 
between connectors CH1 and CH2 on the panel 
PCB and the FDD.

• Replace the floppy disk drive.
