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 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 r eturn 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

1.1.2. LEAKAGE CURRENT HOT CHECK

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.

Figure 1

1.2. Before Repair and Adjustment

Disconnect AC power to discharge unit AC Capacitors as such C5700, C5701, C5703, C5704, C5705 through a 10 Ω,10W resistor to ground.

Caution:

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 120 V, 60 Hz in NO SIGNAL mode volume minimal should be ~ 900 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

SA-PT750PL

“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.

1.4. Safety Parts Information

Safety Parts List:

There are special components used in this equipment which are important for safety. These parts are marked by should be replaced with manufacturer’s specified parts to prevent shock, fire or other hazards. Do not modify the original design without permission of manufacturer.

2 Prevention of Electrostatic 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 electrostatic 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 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, 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 installed.

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).

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 in the traverse unit.

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 unitand 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 conductive 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.

8.2. Wireless Features

8.2.1. Function Overview

Year 2007 PT models support wireless which includes FX65/FX66, wireless subwoofer and FX85 as described below:-

8.2.1.1. FX65/FX66

•

• The FX65/FX66 supports one-way wireless transmission only, that is, it will only transmit wireless audio signal to the rear

• •

surround speakers. The FX65/FX66 receiver module includes a D-AMP and SMPS. The transmitter interfaces with the main unit using serial communications to communicate information such as mute command request, link detection and ID setting request. Maximum range attainable is 15 meters.

8.2.1.2. Wireless Subwoofer (For PT1050 Only)

•

• The wireless subwoofer receiver module is similar in operation with FX65/FX66 in such a way that it only supports one-way

• •

wireless transmission. It also includes a D-AMP and SMPS. The difference in the wireless subwoofer receiver module is the way its hardware interprets the audio it receives from the transmitter since it is the same audio received by the FX65/FX66 receiver. Maximum range attainable is 30 meters.

8.2.1.3. FX85

•

• The FX85 supports the multi-room function wherein it operates as a second room wireless receiver (up to a maximum of two).

• •

Maximum range attainable is 30 meters. It can send commands to the main unit to control functions such as Play, Stop, Forward Skip/Channel Up, Reverse Skip/Channel Down. It also has a built-in DAP pocket for stand-alone operation by inserting a DAP device (e.g. iPod) in the DAP pocket to play the device only via the device’s own control buttons, FX85 cannot control the device using its own buttons. The transmitter interfaces with the main unit using serial communications to communicate information such as mute command request, link detection, ID setting request and button commands from the FX85 buttons (Play, Stop, Forward Skip/Channel Up, Reverse Skip/Channel Down). The FX85 receiver module has the following functions/terminals/buttons:

FX85 BUTTONS FX85 FUNCTIONS FX 85 Power Button D-Amp Selector Button SMPS Play Button D-Port Connector Stop Button ID Set Switch Forward Skip/Channel Up MPort Reverse Skip/Channel Down Volume Control

8.2.2. Block Diagram

•

• There are two types of transmitter cards, Type A and Type B, and two types of receiver modules, Type 1 and Type 2 for the

• •

wireless configuration. The block diagrams below describe the differences of each of the types.

TX Type A

•

• Type A transmitter uses one ADC (Analog to Digital Converter) and transmits audio through Channel 2. Type 1 receiver (Rx)

• •

uses one DAC and output audio through Channel 2. The firmware (that is downloaded to EEPROM IC) multiplexes which channel to listen to (in this case Channel 2 since type A is transmitting from channel 2 In) by setting the baseband accordingly.

RX Type 2

FX65/FX66 surround sound and FX85 second room audio, respectively. Type 2 receiver outputs audio through Channel 2. The software multiplexes which channel to listen to by setting the baseband accordingly. For example, if the receiver is configured as an FX85 receiver (Type 2), the baseband is configured to accept Channel 1 audio transmission and redirect it to Channel 2 Out. If the receiver is set as an FX65/FX66 or wireless subwoofer, the baseband is configured to accept channel 2 audio transmission and redirect it to the same Channel 2 Out.

8.2.3. Activation

•

• FX65/FX66 can be activated in the main unit by using either transmitter Type A or Type B and enabling surround sound by

• •

selecting Surround Music, DPL or Super Surround (Music/Movie).

•

• FX85 Wireless feature is enabled by default when the user uses transmitter type B.

• •

8.2.4. LED Indication

•

• For FX65/FX66, there will be two-color LED that will be used to indicate Power On and Link. If link, the two-color LED will be

• •

green, else, it will be red. For FX85, the front panel will have LED indicators for Standby,, Wireless Link, Charge, Option and Music Port. During Power

On, Standby LED will be OFF. Only during power OFF will this LED be ON (Red). Wireless Link indicator will be ON (Green) when link is established between TX and RX and OFF when link is lost. Pressing the selector button will toggle from any of the selector modes Wireless, Option and Music port. Only the currently selected mode will be ON (Green), the other two will be OFF. Charge LED will be ON (Red) once iPod charging is initiated.

8.2.5. Key Operation (FX85)

•

• Selector Button

• •

This button will be used to select Wireless, Option or M.Port and enabling the corresponding LED indicators for each mode. During Power On, by default, selector mode is set to Wireless when power is initially supplied to the system. But during Power On/OFF button, it will remember the last selector mode setting.

•

• Play Button

• •

This button will send command to the main unit to play CD/DVD as well as the iPod. This function is therefore meaningful only

if the second room selector is in Main Source (with the first room user in CD/DVD or iPod) and iPod.

•

• Stop Button

• •

This button will send command to the main unit to stop CD/DVD as well as the iPod. This function is therefore meaningful only if the second room selector is in Main Source (if the first room user is in CD/DVD mode or iPod) and iPod.

•

• Forward Skip/Channel Up

• •

This button depends on the second room source currently selected. It will be interpreted as a Forward Skip by the main unit if the second room source is in Main Source (with the first room user is in CD/DVD or iPod mode) and iPod. It will be interpreted as a Channel Up (preset channels only) if the second room source is in FM, AM, or XM.

•

• Reverse Skip/Channel Down

• •

This button depends on the second room source currently selected. It will be interpreted as a Reverse Skip by the main unit if the second room source is in Main Source (if the first room user is in CD/DVD or mode) and iPod. It will be interpreted as a Channel Down (preset channels only) if the second room source is in FM, AM, or XM.

•

• Volume Control

• •

Volume control will be local to the FX85 module only. Default volume (TBD) will be set every time power is first supplied to the system or during exit from stand by mode.

SA-PT750PL

•

• ID-setting Operation

• •

ID setting operation can be invoked by pressing fast-forward key in the main unit and three [3] key in the remocon. Once IDsetting is triggered, the receiver must press its ID-setting button within 60 seconds. During this period, the transmitter will be in open connect mechanism whereby any receiver can pair with the transmitter. After this period elapsed, the transmitter will revert back to using close connect code whereby only those receivers which have the same ID as the transmitter will be able to link. The user also has the option to exit the ID setting operation by p ressing the same keys.

•

• iPod Detection and Charging

• •

iPod is detected once inserted on the FX85 and battery charging automatically starts.

−

− The iPod Charging in Standby Mode:

− −

OUpon iPod insertion detection and FX85 is in Power OFF (stand by), FX85 set will enter iPod charging Standby Mode. OThe FX85’s CHARGE LED will light up whenever the iPod is charging. OFX85 will charge the battery up to five hours. After this period, FX85 will not try to recharge the iPod. OAfter battery full condition, even if the iPod is operated such as play, FX85 will not retry to recharge the iPod (timer will start

immediately once iPod is inserted). ORe - charging of the battery in iPod Charging Standby Mode can be done only by removing and reinserting the iPod to the

dock.

−

− The iPod charging in Power On Mode:

− −

OThe iPod automatically charges its battery whenever it is connected during Power ON. OThe FX85’s CHARGE LED will light up whenever the iPod is charging. OFX85 will continue charging the iPod as long as it is inserted (no charging time limit of five hours).

8.2.6. FX Configurations

There are four types of configurations for the FX series. This is explained by the following illustrations below:

Case 1: FX65/FX66

•

• This is the basic configuration of FX65/FX66 whereby it is only receiving wireless surround audio signal from the main set. This

• •

uses a Type A transmitter which is only able to send audio in one direction. Audio is sent using streams AB through Ch 2.

FX65/FX66

CH2/AB

Case 2 A: FX65/FX66 + FX85

•

• In this configuration, a second receiver, an FX85, in another room is listening to another audio source from the main set. The

• •

FX85 also is able to send command to the main set such as Play, Stop, Skip, and Preset Tuner Channel Up/Down. This configuration uses Type B transmitter which is an upgrade of the Type A and can be used on Type 1 (FX65/FX66). This transmitter is able to send audio signal for second room via Ch 1 and first room via Ch 2.

In this configuration, streams AB is used to transmit the audio from main unit to the first room Type 1 receiver (FX65/FX66) via Ch 2. While the second room audio is transmitted through stream CD via Ch 1.

Multi-room + Multi source

CH1/CD

CH2/AB

FX65/FX66

Case 3 A: Wireless Subwoofer

•

• This configuration, Type A transmitter send signals to subwoofer and Type 1 receiver (FX65/FX66) via channel 2, which is the

• •

same audio signals sent to FX65/FX66 as well. The subwoofer only decodes the low frequency signal.

FX85

CH2/AB

Case 3 B: FX65/FX66 + FX85 + Wireless Subwoofer (for PTX7, PT1050)

•

• In this configuration, all audio source for the Type 1 subwoofer and Type 1 first room receiver (FX65/FX66) through streams AB

• •

via Ch 2 and Type 2 second room receiver (FX85) comes from transmitter B through streams CD via Ch 1. For this configuration, the user must perform ID setting for FX85 if it is sold as an accessory, but for bundled type, it already is paired with the transmitter.

• The software will read from an external EEPROM IC to get the selected baseband IC settings. Not all baseband register

• •

settings (a total o f 512 bytes) will be read from the EEPROM IC, though. Aside from getting the baseband settings from the EEPROM IC, it is also used to enable FCC testing, select the application type and entering into doctor mode (this can be enabled also by sending a command via the main unit).

8.2.9. Doctor Mode

•

• For normal operation but automatic frequency selection is disabled, it can enter into Doctor Mode. This feature is hidden from

• •

normal user and will be used by the s ervice center to fix to a particular RF Channel. With doctor mode, the user can disable frequency automatic allocation and sniffer and be able to select a fix RF Channel (Channels 1, 2 or 3) by a combination or remote control keys. Refer to Section 9.4 for Wireless Doctor Mode.
