SAFETY PRECAUTIONS
WARNING:
Service should not be attempted by anyone unfamiliar with the necessary precautions for this recording or playback
equipment. The following precautions are necessary during servicing:
1. Many electrical and mechanical parts in this recorder have
special safety-related characteristics for providing protection against shock, fire and other hazards. These characteristics often go unnoticed in a visual inspection, and the
protection afforded by them cannot necessarily be obtained by using replacement components with higher
ratings (voltage, wattage, etc.).
2. Replacement parts having special safety-related characteristics are identified in this manual, and in the schematic
diagrams, by the symbol
. These components have
values that are of special significance to product safety.
Should any component (identified by the symbol
) need
to be replaced, use only the part designated in the parts
List. Do not deviate from the specified resistance, wattage,
and voltage ratings.
AC VOLTMETER
(5000 ohms per volt or more sensitivity)
Reading should not exceed 300 mVrms
3. Before returning the set to the customer, always perform
an AC leakage current check on the exposed metallic parts
of the cabinet, such as terminals, screwheads, metal
overlays, etc. to be sure that the set is safe to operate
without the danger of electrical shock, Plug the AC line
cord directly into a 120 V AC outlet. (Do not use a line
isolation transformer during this check.) Use an AC voltmeter
with a sensitivity of 5000 ohms per volt (or more) as follows:
Connect a 1500 ohms, 10 watt resistor, paralleled by a 0.15
mfd, 150 VAC capacitor, between a known good earth
ground (water pipe, conduit, etc.) and the exposed metallic
parts, one at a time. Measure the AC voltage across the
1500 ohms resistor and 0.15 mfd capacitor combination.
Reverse the AC plug at the AC outlet and repeat the AC
voltage measurements for each exposed metallic part.
The measured voltage must not exceed 300 mVrms. This
corresponds to 200 µA AC. Any value exceeding this limit
constitutes a potential shock hazard and must be corrected
immediately.

WARNING
Do not use solder containing lead.
This product has been manufactured using lead-free
solder in order to help preserve the environment.
Because of this, be sure to use lead-free solder when
carrying out repair work, and never use solder
containing lead.
Lead-free solder has a melting point that is 30 - 40°C (86 104°F) higher than solder containing lead, and moreover it
does not contain lead which attaches easily to other metals.
As a result, it does not melt as easily as solder containing
lead, and soldering will be more difficult even if the
temperature of the soldering iron is increased.
The extra difficulty in soldering means that soldering time
will increase and damage to the components or the circuit
board may easily occur.
Because of this, you should use a soldering iron and
solder that satisfy the following conditions when carrying out
repair work.
Note:
If replacing existing solder containing lead with lead-free
solder in the soldered parts of products that have been
manufactured up until now, remove all of the existing solder
at those parts before applying the lead-free solder.
Soldering iron
Use a soldering iron which is 70 W or equivalent, and
which lets you adjust the tip temperature up to 450°C
(842°F). It should also have as good temperature recovery
characteristics as possible.
Set the temperature to 350°C (662°F) or less for chip
components, to 380°C (716°F) for lead wires and similar,
and to 420°C (788°F) when installing and removing shield
plates.
The tip of the soldering iron should have a C-cut shape or
a driver shape so that it can contact the circuit board as flat
or in a line as much as possible.
Solder
Use solder with the metal content and composition ratio by
weight given in the table below. Do not use solders which
do not meet these conditions.
Metal content Tin (Sn) Silver (Ag) Copper (Cu)
Composition
ratio by weight
96.5% 3.0% 0.5%
Lead-free solder is available for purchase as a service tool.
Use the following part number when ordering:
Part name: Lead-free solder with resin (0.5 mm dia., 500 g)
Part number: VJ8-0270

This section describes to adjust LCD monitor after replacing EEPROM, Main PBA or Panel.
2-1 Program Upgrade
Change MICOM
: If the similar happenings occur, EEPROM can be changed
-. EX1) When screen appears but remote control and function key aren't working
-. EX2) When LED is on but the screen doesn't appear
-. EX3) After mass production, when the micom program version is up-graded
* MICOM replacement can be done when Service Bulletin issue is in practice.
The process of working need to be prepare on Service Bulletin.
As the visual sample shown, after disassembling the set (refer to SET disassemble), remove the Micom in
the exist IC202 Socket and replace new Micom.
- Use appropriate JIG or any sharp tool and place in the both corners to assist in removing.
(Be aware! If the socket cause any damage after replacement the monitor will not function properly.)
- When inserting, attend to IC No.1 direction and press with suitable amount of strength.
- After replacement, in case of EEPROM Clear, enter to Factory mode and perform into action.
