3.1 Overview
There is no function to indicate an error on this camera. Code
indications, which sometimes are indicated on the LCD when the
camera is in abnormal situation, are not reliable since they are still in the
developing stage of ASIC, and it is difficult to find the specific
malfunction. Also, sometimes several different malfunctions can be
found from the same symptom. Therefore, check each checkpoints
according to the procedures in this chapter and perform proper repair
service.
Table 3-1. First/Second Maintenance
W A R N I N G
Before disassembling the camera, make sure that
batteries are removed or AC adapter is disconnected.
Electrolytic condenser(C5412) mounted on the ST1
board is for flash emission. This condenser is charged
automatically everytime the power is turned on.
Therefore, since there is a possibility to get electric
shock during the service operation, release the
electricity by using the cement resistance, if you need
to touch the condenser for repair service. (See
Chapter 4 for more details)
