1.1. INTRODUCTION
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.
IMPOTANT NOTICE 1: (Other than U.S.A. and Canadian Market)
1. The service manual does not contain the following information, because of the impossibility of servicing at component level.
a. Schematic diagram, Block Diagram and C.B.A. layout of Main C.B.A.
b. Parts list for individual parts of Main C.B.A.
When a part replacement is required for repairing Main C.B.A., replace as an assembled parts. (Main C.B.A.)
2. The following category is/are recycle module part. please send it/them to Central Repair Center.
·
MAIN C.B.A. (VEP23537B) : For DMC-LC40E/B/A/EN (Excluding replacement of Lithium Battery)
NOTE:
The MAIN C.B.A. for this model seems to be divided into three boards; Terminal board, Main board and Digital board.
However, these three boards connected by flexible card directly, without connector.
Therefore, when servicing, it has to be handled as 1pc of P.C.B. named MAIN C.B.A.
IMPOTANT NOTICE 2:
The following listed category is/are not repairable at component level.
·
Lens unit (1)
CAUTION / IMPORTANT. (WHEN HANDLING THE MAIN C.B.A.)
1. DO NOT PRESS AND BENT THE JUNCTION AREA OF MAIN C.B.A.
Since the Terminal board, Main board and Digital board of the Main C.B.A. are directly connected with Flexible Card, these
junction areas are quite delicate.
junction areas are quite delicate.
Therefore, DO NOT hardly press and bent the junction areas of Main C.B.A.

1.2. HOW TO DEFINE THE MODEL SUFFIX (NTSC or PAL model)
There are only two kinds of DMC-LC40, one is the DMC-LC40PP (NTSC model) and the other one is DMC-LC40E/B/A/EN (PAL
models), in terms of the unit itself, regardless colours.
models), in terms of the unit itself, regardless colours.
What is the difference is that the data, which is stored in Flash ROM located on MAIN C.B.A.
To define the unit to be serviced, refer to the name plate which is putted on the bottom side of the Unit.
NOTE:
After replacing the MAIN C.B.A., be sure to write the data in Flash ROM with TATSUJIN KIT in accordance with the instruction
given by TATSUJIN KIT.
given by TATSUJIN KIT.
(There are two kinds of the Flash ROM data, one is NTSC version and the other one is PAL version.)
Then, adjust and/or confirm that each adjustment value or performance to be within specification.

2 SAFETY PRECAUTIONS
2.1. GENERAL GUIDELINES
1. IMPORTANT SAFETY NOTICE
There are special components used in this equipment
which are important for safety. These parts are marked by
which are important for safety. These parts are marked by
in the Schematic Diagrams, Circuit Board Layout,
Exploded Views and Replacement Parts List. It is essential
that
that
these
critical
parts
should
be
replaced
with
manufacturer’s specified parts to prevent X-RADIATION,
shock, fire, or other hazards. Do not modify the original
design without permission of manufacturer.
shock, fire, or other hazards. Do not modify the original
design without permission of manufacturer.
2. An Isolation Transformer should always be used during the
servicing of AC Adaptor whose chassis is not isolated from
the AC power line. Use a transformer of adequate power
rating as this protects the technician from accidents
resulting in personal injury from electrical shocks. It will also
protect AC Adaptor from being damaged by accidental
shorting that may occur during servicing.

3. When servicing, observe the original lead dress. If a short
circuit is found, replace all parts which have been
overheated or damaged by the short circuit.

4. After servicing, see to it that all the protective devices such
as insulation barriers, insulation papers shields are properly
installed.
installed.
5. After servicing, make the following leakage current checks
to prevent the customer from being exposed to shock
hazards.
hazards.
2.2. LEAKAGE CURRENT COLD
CHECK
1. Unplug the AC cord and connect a jumper between the two
prongs on the plug.
2. Measure the resistance value, with an ohmmeter, between
the jumpered AC plug and each exposed metallic cabinet
part on the equipment such as screwheads, connectors,
control shafts, etc. When the exposed metallic part has a
return path to the chassis, the reading should be between 1
M
part on the equipment such as screwheads, connectors,
control shafts, etc. When the exposed metallic part has a
return path to the chassis, the reading should be between 1
M
Ω
and 5.2 M
Ω
. When the exposed metal does not have a
return path to the chassis, the reading must be infinity.
2.3. LEAKAGE CURRENT HOT
CHECK (See Figure 1.)
1. Plug the AC cord directly into the AC outlet. Do not use an
isolation transformer for this check.
2. Connect a 1.5 k
Ω
, 10 W resistor, in parallel with a 0.15 µF
capacitor, between each exposed metallic part on the set
and a good earth ground, as shown in Figure 1.
and a good earth ground, as shown in Figure 1.
3. Use an AC voltmeter, with 1 k
Ω
/V or more sensitivity, to
measure the potential across the resistor.
4. Check each exposed metallic part, and measure the
voltage at each point.
5. Reverse the AC plug in the AC outlet and repeat each of the
above measurements.
6. The potential at any point should not exceed 0.75 V RMS.
A leakage current tester (Simpson Model 229 or equivalent)
may be used to make the hot checks, leakage current must
not exceed 1/2 mA. In case a measurement is outside of
the limits specified, there is a possibility of a shock hazard,
and the equipment should be repaired and rechecked
before it is returned to the customer.
