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. The camera turns on under AC power but not under battery power

Fault details: The camera turns on under AC power but not under battery power. Analysis results: Confirmed that replacing the MB_PCB UNIT rectified the problem.

Repair details:

Replace the MB_PCB UNIT.

1-2. The camera does not turn off

Fault details: The camera does not turn off. Analysis results: Simply connecting the AC adapter turns the camera on. Confirmed that replacing the
