Table Caption: This table outlines the disassembly procedure for a camera, detailing various components and units to be removed in a sequential order, with corresponding page numbers for each step.
1. Before Starting the Repair Work
Be sure to read the following precautions before starting the repair work.
1.1 Precautions on Flash High Voltage Circuit
- ¥ After the DC/DC PCB ASS'Y is removed, be sure to discharge the main capacitor. (Discharging resistor: 1 k Ω , approx. 5 W.)
- ¥ First contact the GND terminal of the main capacitor with the discharging resistor. Then contact the positive terminal of the main capacitor.
CAUTION:
This is a high voltage circuit, so be careful of electric shock.
