COMPONENT                                   CHECKOUT PROCEDURE                                             RESULTS

Measure the resistance : Across two terminals with an 
ohm-meter on its highest scale.

Normal reading :
Indicates continuity. 

Abnormal reading :
Indicates infinite ohms. 

Measure the voltage : Between test points TP-1,TP-2,TP-3, 
TP-4 and ground or between TP-5, and TP-6. ( See 
control circuit board on page 20 ).

NOTE

Proceed with the check of the step down transformer, to
see if any one of the measured values is different from the 
specified values

Measure the resistance between terminals of FPC
connector after removing it from S101. ( See Figure
11).

NOTE

- When reconnecting the FPC connector, make sure
the holes on the connector are properly inserted in
hooks of the plastic fastener in S101.
