• Is the output voltage of the supply voltage

regulator for the FAN in the power circuit

normal?

• Has dust accumulated in the FAN?

If the output voltage is not abnormal,

replace the faulty FAN with a new one.

• Check the faulty device through the self

diagnostics function under SERVICE mode.

• Does BUS line (SCL, SDA) work normally?

If the BUS line is under abnor mal

conditions, replace the faulty device with

a new one.

• Is the output voltage of the power supply

circuit normal?

If the output voltage is normal, replace the
