1 Safety precautions
2 Before Repair and Adjustment
Disconnect AC power, discharge Power Supply Capacitors C531~C534, C588~C589, C598~C599 and C954 through a 10Ω,5W
resistor to ground.
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 110/127/220~230V, 50/60 Hz in NO SIGNAL (vol. min, at CD mode) & AC 240 V, 50 Hz should be
~770mA .
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 speaker systems with an impedance less than the indicated rated impedance of the amplifier are used.
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.

4 Safety Precautions
4.1. 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, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
4.1.1. 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 1MΩand 5.2MΩ.
When the exposed metal does not have a return path to the chassis, the reading must be ･.
Figure 1
4.1.2. 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 capacitor, 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 out 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.
5 Prevention of Electro Static Discharge (ESD) to
Electrostatically Sensitive (ES) Devices
Some semiconductor (solid state) devices can be damaged easily by 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-equiped 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 equiped with ES devices, place the assembly on a conductive surface such as aluminium
foil, to prevent electrostatic charge build up 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 remover device. Some solder removal devices not classified as “anti-static (ESD protected)” can
generate electrical charge to damage ES devices.
5
SA-VK61DGS
All manuals and user guides at all-guides.com

5.Do not use freon-propelled chemicals. These can generate electrical charges sufficient 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, aluminium 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 installed.
Caution
Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
8.Minimize body 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).
6 Handling the Lead-free Solder
6.1. About lead free solder (PbF)
Distinction of PbF P.C.B.:
P.C.B.s (manufactured) using lead free solder will have a PbF stamp on the P.C.B.
Caution:
· Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please
use a high temperature soldering iron. In case of soldering iron with temperature control, please set it to 700 ± 20°F (370 ±
10°C).
· Pb free solder will tend to splash when heated too high (about 1100°F/600°C).
· When soldering or unsoldering, please completely remove all of the solder on the pins or solder area, and be sure to heat the
soldering points with the Pb free solder until it melts enough.

7 Cautions to be taken when handling Optical Pickup
The laser diode used inside optical pickup could be destroyed due to static electricity as a potential difference is caused by
electrostatic load discharged from clothes or human body. Handling the parts carefully to avoid electrostatic destruction during
repair.
7.1. Handling Optical Pickup
1.Do not impact on optical pickup as the unit structurally uses an extremely precise technology.
2.Short-circuit the flexible cable of optical pickup remove from the circuit board using a short-circuit pin or clip in order to prevent
laser diode from electrostatic destruction (Refer to Fig. 7.1 and Fig. 7.2)
3.Do not handle flexible cables forcibly as this may cause snapping. Handle the parts carefully (Refer to Fig. 7.1)
4.A new optical pickup is equipped with an anti-static flexible cable. After replacing and connecting to the flexible board, cut the
anti-static flexible cable. (Refer to Fig. 7.1)
Fig. 7.1
7.2. Replacing Precautions for Optical Pickup Unit
DVD/CD Optical Pickup
The optical pickup by which part supply was carried out attaches the short clip to the flexible board for laser diode electrostatic
discharge damage prevention. Please remove the short clip and be sure to check that the short land is open, before connecting.
(Please remove solder, when the short land short-circuits.)
7.3. Grounding for Preventing Electrostatic Destruction
1.Human body grounding
Use the anti-static wrist strap to discharge the static electricity accumulated in your body. (Refer to Fig. 7.2)
2.Work place grounding
Place a conductive material (conductive sheet) or ironboard where optical pickup is placed. (Refer to Fig. 7.2)
Note :
Keep your clothes away from optical pickup as wrist strap does not release the static electricity charged in clothes.

easy to operate for the user.
12.2. Why use HighMAT?
Up to now, there was no harmonized standard from playing digital content stored in CD-ROM formats (including CD-R) on
consumer products like DVD players.Therefore, we used to have problems such as follow:
· There was no common play list or attached information on contents, which is called metadata.
· The data compression method differed according to the equipment.
· As the number of CD-ROMs recorded increased retrieved the contents became more difficult.
· Because display and operation methods were different depending on the equipment, the play order of the content on the same
disc could change.
12.3. The advantages of using HighMAT
Applying the HighMAT standard will solve the following problems and will improve usability.
· It will create a common user interface for both PC and consumer products.
· Regardless of the types of consumer products, such as DVD players, portable CD players, car stereos, and micro computers,
a consistent way to pay for digital content will be created and it will make it easier to retrieve data.
