0．Trouble shooting(4D-970)）

■Precautions for repair or exchange

a. Make sure to unplug when you exchange parts, teardown, inserting or removing the connector. b. Make sure to work for repair after following actions when you touch main circuit board(each board) as semiconductor(Ex. IC) is static-sensitive.

※Remove human earth or touch an earth(Ex. refrigerator, washing machine) directory by hand and release the static from

electrically charged body.

c. Do not touch power supply board without discretion as high(AC100V～240V) and low(24V・12V・5V) pressure are mixed in the power supply board. It may cause electric shocks. Please be very careful with checking voltage.

１．Power does not turn ON

(4D-970：LCD does not light up)

Is the power cord plug connected?
