Panasonic Digital Camera Service Manual

1. Service Navigation

1.1. Introduction

This Service Manual contains technical information to assist service personnel in understanding and servicing the Digital Camera DMC-FS12 series. The DMC-FS12 series has been developed based on the DMC-FS7 series. This manual does not cover parts already described in the Service Manual for the DMC-FS7 series. When servicing, refer to the descriptions in the Service Manual for DMC-FS7P/PC/PR/PU/EB/EE/EF/EG/EP/GC/GD/GJ/GK/GN/GT (Order No. DSC0902005CE) (Service Manual Vol. 1).

1.2. Important Notice 1: (Other than U.S.A. and Canadian Market)

When a part replacement is required for repairing the MAIN PCB, replace it as an assembled part. The following category is a recycle module part; please send it to the Central Repair Center: MAIN PCB: VEP56074F.

1.3. About the Lens Unit

Although this service manual (for DMC-FS12) is designed based on the service manual for DMC-FS7, the lens unit for DMC-FS12 is a single type. Therefore, only the defective part needs to be replaced. There is no need to distinguish lens types or limitations on replacement parts as described in the service manual for FS7. Refer to the "Disassembly and Assembly Instructions" and "Exploded views" for details.

2. Initial Settings

After replacing the MAIN PCB, perform the initial settings according to the model suffix of the unit. Ensure adjustments are made following the specified procedure.

2.1. Important Notice

Before proceeding with initial settings, carefully read the following CAUTIONS.

2.2. Procedures

Precautions

Read "CAUTION 1" and "CAUTION 2" carefully.

Preparation

1. Attach the Battery or AC Adaptor with a DC coupler to the unit.
2. Set the recording mode to the [NORMAL PICTURE] mode. Press the [MODE] button, select [NORMAL PICTURE] using the [UP] and [DOWN] cursor buttons, and then press the [MENU/SET] button.

NOTE: If the unit is not in [NORMAL PICTURE] mode, the initial settings menu will not display.

Step 1: Temporary Cancellation of "INITIAL SETTINGS"

Set the [REC]/[PLAYBACK] selector switch to [REC] (Camera mark). While holding down the [UP] cursor button and the [iA] button simultaneously, turn the Power on.

Step 2: Cancellation of "INITIAL SETTINGS"

Set the [REC]/[PLAYBACK] selector switch to [PLAYBACK]. Press the [UP] cursor button and the [iA] button simultaneously, then turn the Power off.

Step 3: Turn the Power On

Set the [REC]/[PLAYBACK] selector switch to [REC] (Camera mark), and then turn the Power on.

Step 4: Display the INITIAL SETTING Menu

NOTE: If the unit is not in [NORMAL PICTURE] mode, the initial settings menu will not display. While holding down the [MENU/SET] button and the [RIGHT] cursor button simultaneously, turn the Power off. The "INITIAL SETTINGS" menu will be displayed.

There are two kinds of "INITIAL SETTINGS" menu forms:

Case 1: After Replacing MAIN P.C.B.

When the MAIN P.C.B. has just been replaced, all model suffixes are displayed (four pages in total).

Case 2: Other than "After Replacing MAIN P.C.B."

Step 5: Choose the Model Suffix in "INITIAL SETTINGS"

Caution: After replacing the MAIN P.C.B., the model suffix can be chosen only once. Once a model suffix is chosen, the list will not be displayed again, and it cannot be changed. Therefore, select the area carefully. Select the area by pressing the [UP] / [DOWN] cursor buttons.

Step 6: Set the Model Suffix in "INITIAL SETTINGS"

Press the [RIGHT] cursor button. The selected area will be displayed. Press the [RIGHT] cursor button again after confirmation. The unit will power off automatically.

Step 7: Confirmation

Confirm the display of "PLEASE SET THE CLOCK" in the concerned language when the unit is turned on again. When the unit is connected to a PC with a USB cable, it is detected as removable media.

Default Setting (After "INITIAL SETTINGS")
