This service manual contains technical information, which allow service personnel’s to understand and service this model.
Please place orders using the parts list and not the drawing reference numbers.
If the circuit is changed or modified, the information will be followed by service manual to be controlled with original service manual.

The lead free solder has been used in the mounting process of all electrical components on the printed circuit boards used for this
equipment in considering the globally environmental conservation.
The normal solder is the alloy of tin (Sn) and lead (Pb). On the other hand, the lead free solder is the alloy mainly consists of tin
(Sn), silver (Ag) and Copper (Cu), and the melting point of the lead free solder is higher approx.30

°C (86°F) more than that of the

normal solder.
Distinction of PCB Lead Free Solder being used

• The lead free solder has to be used when repairing the equipment for which the lead free solder is used.

(Definition: The letter of “PbF” is printed on the PCB using the lead free solder.)

• To put lead free solder, it should be well molten and mixed with the original lead free solder.
• Remove the remaining lead free solder on the PCB cleanly for soldering of the new IC.
• Since the melting point of the lead free solder is higher than that of the normal lead solder, it takes the longer time to melt the

lead free solder.

• Use the soldering iron (more than 70W) equipped with the temperature control after setting the temperature at 350±30

°C

(662±86

°F).

• The following 3 types of lead free solder are available through the service parts route.

RFKZ03D01K-----------(0.3mm 100g Reel)
RFKZ06D01K-----------(0.6mm 100g Reel)
RFKZ10D01K-----------(1.0mm 100g Reel)

* Ingredient: tin (Sn) 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%

1. The service manual does not contain the following information, because of the impossibility of servicing at component level

without concerned equipment/facilites.

a. Schematic diagram, Block Diagram and PCB layout of MAIN PCB and SD/AFE PCB.
b. Parts list for individual parts for MAIN PCB and SD/AFE PCB.

When a part replacement is required for repairing MAIN PCB and/or SD/AFE PCB, replace as an assembled parts. (MAIN
PCB, SD/AFE PCB)

2. The following category is/are recycle module part. please send it/them to Central Repair Center.

• MAIN PCB (VEP56033A)
• SD/AFE PCB (VEP53030A)

There are six kinds of DMC-TZ1, regardless of the colours.

• a) DMC-TZ1S
• b) DMC-TZ1PP
• c) DMC-TZ1EB/EF/EG/EGM/GN
• d) DMC-TZ1EE
• e) DMC-TZ1GT
• g) DMC-TZ1PL/GC/GK/SG

(DMC-TZ1S is exclusively Japan domestic model.)
What is the difference is that the “INITIAL SETTINGS” data which is stored in Flash ROM mounted on Main PCB.

To define the model suffix to be serviced, refer to the nameplate which is putted on the bottom side of the Unit.

After replacing the MAIN PCB, be sure to achieve adjustment.
The adjustment instruction is available at “software download” on the “Support Information from NWBG/VDBG-PAVC” web-site
in “TSN system”, together with Maintenance software.

When you replace the Main PCB be sure to perform the initial settings after achieving the Adjustment, by ordering the following pro-
cedure in accordance with model suffix.

• Step 1. The temporary cancellation of factory setting:

Set the mode dial to “[ Normal picture mode ] (Red camera mark)”. 
While keep pressing [ Optical Image Stabilizer ] and “[ UP ] of Cross key” simultaneously, turn the Power on.

• Step 2. The cancellation of factory setting:

Set the mode dial to “[ Playback ]”.
Press [ Optical Image Stabilizer ] and “[ UP ] of Cross key” simultaneously, then turn the Power off.

• Step 3. Turn the Power on:

Set the mode dial to “[ Normal picture mode ] (Red camera mark)”, and then turn the Power on. 

• Step 4. Display the INITIAL SETTING:

While keep pressing [ MENU ] and “[ RIGHT ] of Cross key” simultaneously, turn the Power off. 

• Step 5. Set the INITIAL SETTING:

Select the area with pressing “[ UP ] / [ DOWN ] of Cross key”, and then press the “[ RIGHT ] of Cross key”.

The only set area is displayed, and then press the “[ RIGHT ] of Cross key” after confirmation.
(The unit is powered off automatically.) 
Confirm the display of “PLEASE SET THE CLOCK” in English when the unit is turned on again.

• Step 6. CONFIRMATION:

The display shows “PLEASE SET THE CLOCK” when turn the Power on again.
When the unit is connected to PC with USB cable, it is detected as removable media.
(When the “GT” or “GK” model suffix is selected, the display shows “PLEASE SET THE CLOCK” in Chinese.)

1) As for your reference Default setting condition is given in the following table.
