1 Safety Precautions
1.1. GENERAL GUIDELINES
1. 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.
2. After servicing, see to it that all the protective devices such as insulation barriers, insulation papers shields are properly
installed.
3. After servicing, carry out the following leakage current checks to prevent the customer from being exposed to shock hazards.
1.1.1. LEAKAGE CURRENT COLD CHECK
1. Unplug the AC cord and connec t 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 1MΩ and 5.2MΩ .
When the exposed metal does not have a return path to the chassis, the reading must be
.
Figure 1
1.1.2. 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 1.5kΩ, 10 watts resistor, in parallel with a 0.15µF capacitors, between each exposed metallic part on the set and a
good earth ground such as a water pipe, as shown in Figure 1.
3. Use an AC voltmeter, with 1000 ohms/volt 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 volts 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 milliamp. 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.
1.2. Before Repair and Adjustment (Using SMPS)
This model uses Switching Mode Power Supply (SMPS) Module to provide the neccessary voltages for the unit.
DO NOT SHORT-CIRCUIT DIRECTLY (with a screwdriver blade, for instance), as this may destroy solid state devices.
After repairs are completed, restore power gradually using a variac, to avoid overcurrent.
Current consumption at AC 100/ 110V, 50/ 60 Hz in NO SIGNAL mode volume minimal should be ~ 650 mA.
Current consumption at AC 230V~240V, 50 Hz in NO SIGNAL mode volume minimal should be ~ 650 mA.
1.3. Protection Circuitry
The protection circuitry may have operated if either of the following conditions are noticed:
·No sound is heard when the power is turned on.
·Sound stops during a performance.
The function of this circuitry is to prevent circuitry damage if, for example, the positive and negative speaker connection wires are
“shorted”, or if speake r systems with an impedance less than the indicated rated impedance of the amplifi er are used.
6
Page 7
SA-HT340GC / SA-HT340G CS / SA-HT340GS
If this occurs, follow the procedure outlines below:
1. Turn off the power.
2. Determine the cause of the problem and correct it.
3. Turn on the power once again after one minute.
Note:
When the protection circuitry functions, the unit will not operate unless the power is first turned off and then on again.
1.4. Caution for AC Cord (For GS only)

2 Prevention of Electro Static Discharge (ESD) to
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called
Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and
semiconductor "chip" components. The following techniques should be used to help reduce the incidence of component damage
caused by electro static discharge (ESD).
1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your
body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap,
which should be removed for potential shock reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as
aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly.
3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.
4. Use only an anti-static solder removal device. Some solder removal devices not classified as "anti-static (ESD protected)" can
generate electrical charge sufficient to damage ES devices.
5. Do not use freon-propelled chemicals. These can generate electrical charges sufficie nt to damage ES devices.
6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most
replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable
conductive material).
7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material
to the chassis or circuit assembly into which the device will be installe d.
Caution
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the
brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD)
sufficient to damage an ES device).

4 About Lead Free Solder (PbF)
4.1. Service caution based on legal restrictions
4.1.1. General description about Lead Free Solder (PbF)
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 degrees C (86°F) more than that
of the normal solder.
Definition of PCB Lead Free Solder being used
The letter of “PbF” is printed either foil side or components side on the PCB using the lead free solder.
(See right figure)
Service caution for repair work using Lead Free Solder (PbF)
· 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
degrees C (662±86°F).
Recommended Lead Free Solder (Service Parts Route.)
· 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)
Note
* Ingredient: tin (Sn), 96.5%, silver (Ag) 3.0%, Copper (Cu) 0.5%, Cobalt (Co) / Germanium (Ge) 0.1 to 0.3%

5 Handling Precautions for Traverse Unit
The laser diode in the optical pickup unit may break down due to static electricity of clothes or human body. Special care must be
taken avoid caution to electrostatic breakdown when servicing and handling the laser diode.
5.1. Cautions to Be Taken in Handling the Optical Pickup Unit
The laser diode in the optical pickup unit may be damaged due to electrostatic discharge generating from clothes or human body.
Special care must be taken avoid caution to electrostatic discharge damage when servicing the laser diode.
1. Do not give a considerable shock to the optical pickup unit as it has an extremely high-precise structure.
2. To prevent the laser diode from the electrostatic discharge damage, the flexible cable of the optical pickup unit removed should
be short-circuited with a short pin or a clip.
3. The flexible cable may be cut off if an excessive force is applied to it. Use caution when handling the flexible cable.
4. The antistatic FPC is connected to the new optical pickup unit. After replacing the optical pickup unit and connecting the flexible
cable, cut off the antistatic FPC.
5.2. Grounding for electrostatic breakdown prevention
Some devices such as the DVD player use the optical pickup (laser diode) and the optical pickup will be damaged by static
electricity in the working environment. Proceed servicing works under the working environment where grounding works is
completed.
5.2.1. Worktable grounding
1. Put a conduc tive material (sheet) or iron sheet on the area where the optical pickup is placed, and ground the sheet.
5.2.2. Human body grounding
1. Use the anti-static wrist strap to discharge the static electricity form your body.

12.2. Important points in adjustment
12.2.1. Important points in optical adjustment
·Before starting optical adjustment, be sure to take anti-static measures.
·Optical pickup tilt adjustment is needed after replacement of the following components.
1. Optical pickup unit
2. Spindle motor unit
3. Optical pickup peripheral parts
Notes
Adjustment is generally unnecessary after replacing other parts of the traverse unit. However, make adjustment if there is a
noticeable degradation in picture quality. Optical adjustments cannot be made inside the optical pickup. Adjustment is generally
unnecessary after replacing the traverse unit.
12.2.2. Important points in electrical adjustment
·Follow the adjustment procedures described in this manual.
12.3. Storing and handling of test discs
· Surface precision is vital for DVD test discs. Be sure to store and handle them carefully.
1. Do not place discs directly onto the workbench, etc., after use.
2. Handle discs carefully in order to maintain their flatness. Place them into their case after use and store them vertically. Store
discs in a cool place where they are not exposed to direct sunlight or air from air conditioners.
3. Accurate adjustment will not be possible if the disc is warped when placed on a surface made of glass, etc. If this happens, use
a new test disc to make optical adjustments.
4. If adjustment is done using a warped disc, the adjustment will be incorrect and some discs will not be playable.

Measuring equipmentAdjustment value
None (Main unit display for servicing is used.)Adjust to the minimum jitter value.
12.4.1.1. Adjustment procedure
1. While pressing STOP button on the main unit, press "5" on
the remote control unit.
2. Confirm that "J_xxx/yyy_z z" (display1/display2) is shown on
the front display.
For your information:
"yyy" and "zz" shown to the right have nothing to do with
the jitter value. "yyy" is the error counter, while "zz" is
the focus drive value.
Note:
Jitter value appears on the front display.
3. Play test disc T30 (center periphery).
4. Adjust tangential adjustment screw so that the jitter value is
minimized.
5. Play test disc T30 (center periphery).
6. Adjust tilt adjustment screw 1 so that the jitter value is
minimized.
7. Play test disc T30 (center periphery).
8. Adjust tilt adjustment screw 2 so that the jitter value is
minimized.
9. Repeat adjusting tilt adjustment screws 1 and 2 alternately
until the jitter value is minimized.
12.4.1.2. Important points
1. Make tangential adjustment first, and then make tilt
adjustment.
2. Repeat adjusting two or three times to find the optimum
point.
3. Finish the procedure with tilt adjustment.
T01 (inner periphery) play
T30 (center periphery)
T43 (outer periphery) play
12.4.1.3. Check after adjustment
Play test disc or any other disc to make sure there is no picture
degradation in the inner, middle and outer peripheries, and no
audio skipping. After adjustment is finished, lock each
adjustment screw in position using screw lock.
12.4.1.4. Procedure for screw lock
1. After adjustment, remove top cover, tray, clamper base and
traverse unit in this sequence.
2. Lay the traverse unit upside down, and fix adjustment screw
with screw lock.
3. After fixing, reassemble traverse unit, clamper base, tray
and top cover.
SA-HT340GC / SA-HT340G CS / SA-HT340GS
DVDT-S20 [SPG]
Jitter value depends on the model:
1. If the jitter value changes like B, the optimum point is easy to
find.
2. If the jitter value changes like A, set the optimum point near the
middle.
