SAFETY CHECK-OUT

After correcting the original problem, perform the following

safety check before return the product to the customer.

1. Check the area of your repair for unsoldered or poorly soldered connections. Check the entire board surface for solder splasher and bridges.

2. Check the interboard wiring to ensure that no wires are “pinched” or contact high-wattage resistors.

3. Look for unauthorized replacement parts, particularly transistors, that were installed during a previous repair. Point them out to the customer and recommend their replacement.

4. Look for parts which, though functioning, show obvious signs of deterioration. Point them out to the customer and recommend their replacement.

5. Check the B + voltage to see it is at the values specified.

6. Make leakage - current measurements to determine that exposed parts are acceptably insulated from the supply circuit before returning the product to the customer.

1. Power

1-1. Power cuts out in mid-operation.

Fault details: In both Camera mode and Playback mode, the camera sometimes emitted a short beep

and then turned off. Pressing lightly on the battery cover caused this to happen.

Analysis results: Vibration or stress applied to the camera body caused the battery cover detection switch

(SW401) to malfunction and turn the camera off.

Repair details:

The solution was to fit a replacement DCST PWB ASSY with modifications to the SW401 and its surrounding circuits, or to replace the individual parts (See Bulletin GS-2005-022).
