Parts/Service for DSC-RX100M7G

Safety Check-Out

After service, perform these safety checks before returning the camera to the customer:

• Check for unsoldered or poorly-soldered connections, solder splashes, and bridges.
• Ensure interboard wiring is not pinched or touching high-wattage resistors.
• Identify and recommend replacement of unauthorized or deteriorated parts.
• Verify B+ voltage against specifications.

Flexible Circuit Board Repairing

• Use a soldering iron tip at approximately 350°C.
• Avoid touching the same conductor multiple times.
• Do not apply excessive force when soldering or unsoldering.

Unleaded Solder

This unit uses unleaded solder. Boards requiring it are marked with "LF".

• Soldering iron tip temperature: approx. 350°C. If temperature control is unavailable, solder/unsolder quickly at high temperature.
• Be careful not to peel the copper foil by applying the heated tip for too long.
• Unleaded solder is viscous; take care to avoid solder bridges, especially on IC pins.
• Use separate soldering iron tips for unleaded and leaded solder to prevent detachment.

Fine-Wire Coaxial Cable

• Disconnect connectors by the connector, not the wires.
• Connect connectors by the connector, not the wires.

Flash Capacitor Discharging

The flash capacitor is charged at high voltage and poses an electric shock risk.

• The charge does not dissipate when power is off.
• Use a Short Jig to discharge the capacitor.
• Prepare a Short Jig with a 1 kΩ/1 W resistor and small clips on each lead, with the resistor and leads fully insulated.
• Peel off insulating sheet, then short-circuit capacitor terminals for about 10 seconds.
