2. Bluetooth Technology

Chapter 1 - IntroductionThis course covers service training for DV consumer camcorders. DV camcorders are making increasing inroadsin the consumer market: they are displacing analog 8 mm camcorders and compete with digital 8 mm camcorders.

The major advantages of the DV format are:

• Small size, allowing the camcorder to be smaller than 8 mm camcorders.

• Playback capable on professional DV decks.

• Digital compression encoding common to all DV formats, allowing the tape to be edited on professional DVediting equipment.

• Ease of connectivity and editing with PCs.

• The availability of DV cassettes with built-in memory, allowing start/stop edit points to be stored on the cartridge.

Camcorder Features• Streaming Video.

• Wireless Bluetooth featuring BIP (improved Bluetooth capability).

• Networking. Allows camcorder to be connected to the Internet via an optional USB or Bluetooth modem.

• Touch panel. Reduces the switch count and improves reliability.

• USB and DV (i.LINK®) data transfer.

• Still image recording (2.1 mega pixels).

• Analog and digital zoom (10X optical, 12X digital). Total of 120X.

• 3.5" LCD touch screen.

• Color EVF.• Pop-up flash.

• SteadyShot® picture stabilizer.

Course ContentAlthough the course is based on the DCR-TRV80 digital DV camcorder, a great deal of the information providedin the course is also applicable to other current, past and future DV camcorders.

The coursed is “service based” and covers subjects that will help in servicing the camcorder. Theory and signalflow is kept to a minimum and is included only when it is needed to service the camcorder. Circuits that arecommon to most camcorders are not covered.

The course includes short chapters describing the DV format and Bluetooth© technology, including a section onhow to determine of Bluetooth is functioning properly. A chapter dedicated to mechanism servicing is also included.

Chapter 2 - Bluetooth TechnologyOverviewBluetooth is a short-range radio frequency communications technology that allows wireless communications totake place between electronic devices (e.g. computers, cellular telephones, camcorders, PDAs, speakers,headphones and a wide variety of other devices). Bluetooth connects these devices together with minimal userintervention. Think of Bluetooth as a personal network of interconnected devices.

• Bluetooth allows the camcorder to be remotely controlled from Bluetooth-enabled computers or PDAs.• Still pictures and sound can be remotely sent to the computer or PDA.

• The camcorder can become part of a wireless network and send/receive email or “surf the net” via a Bluetoothmodem.

• A USB modem or a USB-Ethernet adapter can also be used for sending and receiving email or “surfing thenet”.

Non-Bluetooth enabled computers can be converted to Bluetooth with either a USB to Bluetooth adapter, a PCcard to Bluetooth adapter, and for desktop computers, a PCI to Bluetooth adapter. These converters normallycost between $30.00 and $100.00.

FIGURE 2-4 - BLUETOOTHPC CARD ADAPTER

Operating Range• Bluetooth operates in the unlicensed ISM band at 2.4GHz, using FHSS (Frequency Hop Spread Spectrum

technology).

• Bluetooth has a typical range of about 10 meters in an unobstructed – line of sight – distance (approximately30 feet). RF output power is 1mw.

• The range decreases when objects are located between the Bluetooth devices.

• Bluetooth can penetrate many non-metallic walls, floors and ceilings, but with reduced range. The rangereduction depends on the material that it has to penetrate; there are no hard and fast rules.

Data Transfer Speed• Maximum effective data transfer speed is 721 kbps.

• At its maximum operating distances, data correction due to signal losses reduces the effective data transferrate.

FIGURE 2-6 - PICONET DCRD01.2-6 8/25/03

Dynamic Configuration and Roaming (Piconet)When Bluetooth equipment comes within communications range of a Bluetooth master device they automaticallyexchange interconnection information and form a small Master/Slave network link called a Piconet.

PiconetBluetooth configures itself automatically. When Bluetooth equipped devices come within communications rangeof each other, they automatically exchange interconnection information and form small networks called Piconets.A Bluetooth network consists of a master, a number of active slave devices and can include a number of standby(sleep mode) slave devices.

1. Initially, a Bluetooth transceiver is in standby mode and is not aware of other devices.

2. When a device comes into the range of a master, they “discover” each other.

3. The master then “pages” the slave and sets up a network called a “Piconet”. The Piconet, in turn, sets up amaster/slave relationship.

4. Once set up, a Piconet can communicate with up to seven active slaves.

5. A Piconet can recognize up to 256 slaves, but can communicate with only seven at a time. The other slavesmust be “parked”.

Bluetooth networks are considered “ad-hoc” and are not saved. They are dynamically created for only one sessionand “wiped out” when all devices go out of range.

6


ScatternetsMultiple Piconets can actively participate with each other as long as their masters are within range of anothermaster. The masters do not all have to be within one 10 meter range. This is called a Scatternet.

Multiple Scatternets can be further evolved into advanced Scatternets spanning great distances and many, many,devices. Scatternet implementation is complex and will not be covered further.

SecuritySimply bringing various Bluetooth devices within range doesn’t mean that they will automatically work with eachother. Security protocols (data scrambling, authentication and privacy) prevent unauthorized interception ofBluetooth transmissions or sending unauthorized data to a Piconet. These security levels and procedures areuser controlled.

AuthenticationAuthentication blocks unspecified users from accessing the network by requiring that the device be registered toa specific network. The details are listed in the back of the network operating manual.

1. Prior to communicating with a network, the devices must first be registered with the network using a commonpassword for all of the devices.

Registration is not required if the device has previously been registered with the network.

2. A security password must then be entered. It must be between 1 and 16 characters long. The password issometimes referred to as a “passkey” or “PIN”.

Co-existing Bluetooth NetworksBecause of security protocols and Frequency Hopping Spread Spectrum technology, several Piconets can coexistin close proximity to each other without privacy and interference problems.

Implementing Bluetooth connectivity is beyond the scope of this training manual; it is contained in a separate 164page users manual that comes with all TRV-80s camcorders.

NetworkingThe TRV80 camcorder can be networked using any of the three following methods:

• Bluetooth (wireless)

• USB-PSTN (Public Switched Telephone Network)

• USB-Ethernet (LAN connection)All three methods need different modem adaptors.

All networking settings and preferences are accessible through the Network Menu in the camcorder under Setup(Network Setup, Network Options and Bluetooth Setup).

A separate Networking owner’s manual describes the camera networking in great detail.

TroubleshootingCamcorders can be easily checked for Bluetooth connectivity. In simple terms, bring the camcorder within rangeof a Bluetooth enabled computer and check if the computer picks up the camcorder. Transmission can beverified if the blue transmit lamp on the camcorder lights up.

EquipmentThe required test items for checking Bluetooth connectivity is a computer with a built-in Bluetooth transceiver oran add-on PC card (for notebook computers), a USB adapter or a PCI adapter.

Procedure1. Turn on the computer and make sure that the computer’s Bluetooth card is actively seeking Bluetooth devices.

How this is done depends on the Bluetooth adapter that is being used. Since we cannot possibly cover all ofthem, the 3COM PC card adapter is used as an example.

2. Power up the camcorder in the camera mode and bring the camcorder within range of the computer.

3. Press the FN button on the lower right corner of the camera screen.

4. Press the PAGE3 button.

5. Press the RMT CAM button. The blue lamp will light on the camera and the following screen will appear on thecamera LCD panel.

The computer should pick up the camcorder within ten seconds after the RMT CAM button is pressed. This willbe confirmed by a message appearing on the computer’s screen. Figure 2-9 is an example of the computerscreen that appears with a 3com PC card. This appearance of this message confirms Bluetooth communica-tions.

3. DV Formats

Chapter 3 - DV FormatsOverviewThere are various DV formats on the market, all offering high video resolution; the lowest quality DV formatexceeds 500 lines or resolution. This is a major improvement over VHS, 8mm and hi8 formats.

All DV formats are based on a similar tape cartridge and a similar video compression codec that provides betterresolutions than MPEG.

DV Cassette StructureDV format cassettes come in two standard sizes: full-size and Mini DV. Sony consumer camcorders use onlythe mini cassette. Almost all DV record and playback decks can record/play mini DV cassettes with a cassetteadapter, and some can accommodate both sizes without an adapter.Recording time ranges between one hour for a Mini-DV cassette to two hours for a full size DV cassette. Figures3-1A and B show both cassette sizes for comparison.

FIGURE 3-1BCASSETTE SIZE

Cassette Memory ICDV cassettes can be purchased with and without NVRAM memory built into the cassette. This memory is usefulwhen editing: it can record start / stop points, access specific recording dates or index points, and can store titlinginformation that can be turned on or off during playback. Cassettes can be purchased with a memory capacity ofup to 16 kilobytes. Sony recommends that only cassettes with memory be used.

FIGURE 3-1ACASSETTE SIZE

10

3. DV Formats

The memory in Sony consumer DV cassettes also stores the tape type, and can also store the dates/times ofmultiple recordings. This information is transmitted over the digital interface.

The presence or lack of a memory IC does not affect the quality of the picture.

FIGURE 3-2A

Memory Cassettes have four copper contacts on the spine and a “memory” symbol with the amount of memoryprinted on the cassette. Figures 3-2A and B show both types.

Recording FormatsFour major DV formats currently exist, three of which will be described here. The fourth has not seen anysignificant acceptance and will not be covered.

• DV and Mini DV formats. These are the original formats and are used in consumer equipment.

• DVCAM. Sony’s professional DV format. It uses a larger track width and a faster tape speed.

• DVPRO. Panasonic’s professional DV format. It uses an even larger track width and even faster tape speed.

Most late model professional DV decks will play back all three formats. Sony Consumer camcorders will playback only Mini DV tapes recorded in DV format.

Note: Mini DV is not a unique recording format. It is simply a DV format that uses smaller size cassettes.

Table 3-1 shows the differences between the three formats.

Audio LockingThe DV format (no suffix) does not use audio locking, while the other DV formats (professional) do. Audio lockingsynchronizes the audio sampling oscillator to the video sampling oscillator, assuring a one hundred percentperfect audio to video synchronization.

For Sony consumer camcorders, audio locking is not necessary because the drift tolerances of the samplingoscillators are so tight that the “worst case” audio to video synchronization drift is one third of a frame, or ±1/90 ofa second; this “worst case” drift would occur only at the end of a tape after it has been recorded in one continuoussession from end to end.

When editing tape that has not been audio locked, a slight clicking sound in the edit transition points may sometimesbe heard in extreme cases. This is not an indication of a defect and should be expected.

RADAR W Interface JigIn addition to the listed items, a RADAR W interface jig and its associated software is also needed; many cameraalignments and repairs must be done with this jig.

RADAR W is used for the following purposes:

• It automates much of the camera alignment process.

• It downloads preset EEPROM data to the camcorder.

• It uploads EEPROM data to a computer so that it can be reused on the camera after making repairs that cancause data loss.

The RADAR W jig is used with many other Sony still and motion consumer camcorders and cameras. Figure 4-1 shows a RM-95 Remote Commander and the RADAR W jig.

RADAR W and RM-95Alignment should be done with the RADAR W interface jig and its associated software and with the AdjustmentRM-95 remote control jig. All adjustments done with RADAR W can also be “forced” with the RM-95, but RADARW is an order of magnitudes faster and unlike the RM-95, it is not prone to user data entry errors.

The Sony part number for the RADAR W interface jig is J-6082-429-A.The RM 95 is an excellent tool for making small registry changes without having to hook up and run RADAR W. Itcan also be used for checking the operation of the camcorder switches. Both are normally needed for camcorderrepairs.

Saving and Getting EEPROM DataThe camera firmware data is stored in two EEPROMS on the VC-316 board. These EEPROMs are essential foralmost every aspect of camera operation.

Since the camera will not operate without the data or with incorrect data, it is extremely important that replacedVC-316 boards have the correct data. Whenever possible, the original data should be used as it reduces or attimes even eliminates the need to realign the camcorder. Without the correct data, every aspect of the camcorderwill have to be realigned.

A number of methods can be used to get correct data to the EEPROMs but the most efficient one is to use theRADAR W jig.

The methods are listed in order of efficiency: Use the less efficient methods only when the more efficient onescannot be implemented.1. With the RADAR W jig, upload and save the original data to a computer; then download it back to the

camcorder after repairs. This method uses all of the original data and requires minimal or no realignment. Itis the most efficient method and should be done whenever possible before repairing a camcorder.

FIGURE 4-2 - DATA DOWNLOAD

FIGURE 4-3 - DATA FROM ANOTHER UNIT

2. A less efficient, but at times necessary, method is to upload the data file from another camcorder (samemodel), then download the data to the repair computer. This requires subsegment realignment.

3. Get default data for the camcorder from the Sony Service Company web site at: http://service.sel.sony.com;Click on the following links: Software downloads ’! RADAR W ’! Master Model List.

4. Swap EEPROMs: Remove the EEPROMs from the old board and put them on the new board. This retains allof the original data and requires minimal or no realignment.

5. Disassembly/Reassembly

Chapter 5 - Disassembly/Reassembly

Disassembling and reassembling the camcorder is not complicated and normally does not present a problem. Itis, however, very important that the service manual be followed when disassembling and reassembling thecamcorder; the manual has crucial disassembly and reassembly diagrams. Following the service manualdisassembly and reassembly procedures will simplify disassembly and assure a proper reassembly.

The information presented in this chapter is an enhancement of the information provided in the service manual.

Figure 5-1 shows an exploded diagram of the board locations. The diagram is clearer than the one in the servicemanual. Table 5-1 lists the functions of the circuit boards.

OverviewThis model uses an LCD panel with a touch control overlay for controlling many of the camera and VTR functionsthat would otherwise be controlled by switches. The LCD panel and the backlight lamp are therefore very crucialfor the camcorder operation.

The LCD panel uses a high voltage fluorescent cold cathode lamp for panel illumination. A high voltage dc-acconverter located on the PD-192 board drives the lamp.

OperationFigure 6-1 is a diagram of the lamp drive circuit.

The cold cathode lamp needs a minimum of 375v to operate at room temperature; with an operating current drawof approximately 3ma. A strike (start) voltage of at least 1kv is needed to start the lamp. A dc-ac converterconsisting of a high frequency oscillator and step-up transformer provides lamp power.In order to provide a higher start voltage, the supply voltage to the oscillator, BL-REG, is increased at lamp startup.

Oscillator• The dc-ac converter oscillator consists of two transistors (Q7502 and Q7503) and step-up transformer T7501.

Its operating frequency is approximately 500 kHz.

• The transformer has a very high secondary to primary turn ratio, providing the high voltage for the lamp.Positive feedback to sustain oscillation is provided by a separate winding of the transformer.

• Power to the converter is provided by the BL_REG line from the power supply circuit. The BL_REG voltageincreases by approximately 3X during startup to provide the high strike voltage for the lamp. The BL_REGvoltage comes from a switched power supply on the DI-089 board.

22


Start/Run SequenceRun OperationLamp current is regulated by a closed loop consisting of BL CURRENT DET IC5702, Timing Generator IC 5502,EVF IC5501, Logic Switch IC5701 and the dc-dc converter in the main power supply of the camera that suppliesthe BL_REG voltage to the lamp oscillator.

Q5702Q5703

1. The lamp current level is sensed by R5710. Its voltage drop is proportional to the lamp current.

2. The voltage across the resistor is rectified by D5703 and applied to BL CURRENT DET IC5702 (dc amplifier).The output of IC5702 is applied to Timing Generator IC5502, which converts the dc voltage level to a digitaldata stream.

3. The data stream output IC5502 is applied to EVF LCD drive IC5501 which contains a DAC. Its output is a dccontrol voltage that is applied to logic switch IC5701/pin 7.

4. During normal operation, pins 1 and 7 of the logic switch IC are interconnected and the dc control voltage isapplied to the main power supply on the DI-089 board, to the feedback line that regulates the BL-REG powersupply line.

Start Operation1. During start operation, the LED line output from timing generator IC5502/pin 8 goes HIGH; this interconnects

pins 1 and 6 of IC5701 together.

2. 2.8v (instead of the normal run voltage of 2.3v) is now applied to the feedback line regulating the BL-REGpower supply line. This increased control voltage increases the BL-REG output to approximately 21 volts,increasing the dc-ac converter output to 1kv.

3. A started LED is placed in close physical proximity to the cold cathode lamp. It lights during startup and helpsthe FL lamp light in cold environments.

On/Off ControlCutting off the power supply to the oscillator turns off the lamp. Controlling logic switch IC5701 with the timinggenerator does this.

1. BL-ON line from timing generator IC5502/pin 4 goes LOW.

2. Q5701 opens and IC5701/pin 2 goes HIGH. This logic level places the logic switch in the floating position(pin 1 is not connected to neither pins 6 pr 7).

3. With no control voltage at the +FB pin of power supply IC4502, the BL_REG line goes to 0V, shutting offthe lamp.

TroubleshootingIt is very important to differentiate between a defective LCD drive circuit and a defective lamp drive circuit becauseboth have the same symptom of no picture.

The logical step in a troubleshooting strategy is to first determine if the problem is related to a defect in the LCDpanel, the video drive to the panel or the backlight power supply. Fortunately, the initial diagnostic steps can bedone without disassembling the camcorder.

• Note: The ac voltage to the FL (fluorescent) backlight cannot be measured with conventional DVMs: Theoscillator impedance is extremely high and the DVM will load the oscillator and shut it down.

• If the video drive to the panel is OK, a contrasting faint picture can be seen on the screen if a strong light isaimed at the panel.

• An unlit lamp can be further isolated to either a lamp problem or a drive circuit problem by verifying if the highvoltage dc-ac inverter is working. This can be done with the backlight jig without opening the unit. A descriptionon making the jig is at the end of this chapter.

24


FIGURE 6-4

Connect the jig to an oscilloscope, place it in the area shown in Figure 6-4 and an ac voltage will be induced in thecoil. With the particular jig used in the illustration, a 150 mv p-p, 500 kHz ac signal is induced in the coil. Dependingon the ferrite coil that you use, the induced voltage may be higher or lower.

• A defective LCD panel open/close switch can also prevent the backlight from turning on. Use the Service RM-95 to test the switch.

Making a Backlight Test JigA backlight HV test jig can be made from a scrap ferrite antenna bar of from an AM radio. Simply connect anoscilloscope to the largest winding on the antenna bar and bring it close to the HV FL dc-ac converter or near theFL lamp itself. A high frequency voltage will be induced in the coil and will be visible on the oscilloscope.

7. Video Signal Flow

Chapter 7 - Video Signal FlowOverviewThe camcorder has many video input and output paths; both analog and digital, which if not properly understoodcan complicate troubleshooting. This chapter describes the signal flow “essentials” to make troubleshootingeasier.

Camera Video• The CCD imager is located on the CD-437 board. The board also contains the sample and hold (S/H) IC that

is crucial in the development of the video signal, as well as the timing generator for the imager and S/H ICs.The video output of the CD-437 board consists of four analog video signals, each containing a discrete part ofthe video (the video signals are: CDD OUT 1P, 1N, 2P, 2N).

• From the CD-437 board, the analog video signals are input to the VC-316 board. They are converted to digitaldata by IC1502 and encoded into DV video by the MPEG type encoder. All DV formats use a modified MPEGcodec. The circled numbers in Figure 7-1 refer to troubleshooting waveforms shown in the service manual.

TroubleshootingInitial AssessmentThe first step is to try to isolate the defective area by assessing how the problem presents itself. For example: ifthe problem is no video in the viewfinder or LCD panel but is present at the S video or A/V jack, then the problemis not likely in the camera section. On the other hand, if the camera video does not appear at any output and is notrecorded by the VTR, then the problem is likely in the camera section rather than in other sections (excluding thepower supply).

CD-437 Board

• This board is a FRU (field replaceable unit). It should be replaced if defective.• Due to layout design, shielding and IC types, directly troubleshooting the board is difficult. Since all lines to

and from this board lead to the VC-316 board, you may want to verify if the condition of the board by checkingthe applicable lines from the VC-316 board.

• Use the procedure outlined on page 2-22 of the Level 2 service manual when replacing or troubleshooting theboard.

• The board has a number of shields to reduce RF radiation from the board and to eliminate light leakage to theCCD imager. Their correct placement is critical.

Troubleshooting VC-316 board

• The board is a FRU (field replaceable unit) and should be replaced if defective. The board has many BGA ICsthat are not field replaceable.

• The board is accessible for “live” troubleshooting even with the camcorder disassembled. Connect thecamcorder components as shown in the service manual. Basic troubleshooting steps consist of checkingfor power, signal tracing and checking data, timing and control lines.

LCD Panel Signal Path Troubleshooting

Troubleshooting the LCD panel signal path is straightforward.

• A defective LCD panel backlight lamp or backlight drive circuit may mimic a “no RGB video drive problem”.Here are some methods that can be used to differentiate between a video and backlight problem withoutopening the camcorder:

If the RGB drive is ok and the problem is backlight related, a very faint outline of the video picture can beseen on the LCD screen when a strong light is thrown at the LCD panel.

Chapter 6 describes a very simple go/no-go test for checking the backlight high voltage dc-ac inverter.

8. Touch Panel and Switch Interfaces

Chapter 8 - Touch Panel and Switch InterfacesOverviewThis model uses a touch panel for controlling most of the camcorder functions. This reduced the switch countand its associated support circuits, and also reduces the “real estate” that would otherwise be dedicated toswitches and they support circuits. Reducing the switch count also increases camcorder reliability and makesthe camcorder more affordable to the consumer.

The switches that are present on the camcorder are used for functions that are not appropriate for touch panelcontrol.

Touch PanelThe pressure sensitive touch panel is overlaid on top of the LCD panel. Although it is physically integrated on topof the LCD display panel, electrically it is not a part of the LCD display. The whole LCD panel assembly must bereplaced if either one is defective.

Signal FlowFour touch signal lines are output from the touch panel: TP_R, TP_L, TP_BOT and TP_TOP. These are sent totransistors Q3102, Q3103 and Q3104 (level shifting, dual pair transistors) and are then processed by IC3102 onthe VC board. Figure 8-1 shows the signal flow from the touch panel to the IC.

Switches and ControlsFigures 8-2 and 8-3 show the interconnect diagrams for all of the camera switches and controls. They arepresented here in a more centralized layout than in the service manuals, allowing for easier diagnosis andsignal flow without the need to page through many schematic diagram pages.

32


ESD ControlMany switches, controls, input/output jacks and connectors incorporate ESD snubbers (anti-static snubbers) toprevent ESD damage to the camcorder. These consist of either varactors or zener diodes. Figure 8-2 shows anexample of a varactor across the A/D control line for switches S8001, S8002 and S8003.

When suspecting that a switch, control line or input/output jack is shorted, first check the ESD snubber acrossthe suspect device or control line to ensure that it is not shorted. A shorted snubber will mimic either a shortedswitch or control line.

Figure 8-3 shows the switches not shown in Figure 8-2.

9. Testing Switches

Chapter 9 - Testing SwitchesOverviewThe camcorder switches are mounted in various locations, some of which are not easily accessible. Thischapter describes a method that uses the Service RM-95 to check the switches without opening the camcorder.

Using the RM-95, suspect switches can be checked to determine if they are functional, open or shorted. This canbe done with the camcorder “live” and without disassembling it.

Note: Switches can also be checked with RADAR W, but using the RM-95 is much simpler unless RADAW W isalready hooked up and running.

Switch Operation1. When a switch is switched or pressed, it changes the value of a data register assigned to the switch. A data

register can be assigned to more than one switch (the change in value depends on which switch is pressed).

2. The camcorder microprocessors, in turn, continuously scan these registers and act according to the valuesin them.

Testing Steps1. Connect the Service RM-95 to the camcorder LANC plug and apply power to the camcorder.2. Enable the RM-95 to read switch data:

• Go to page 0, address 10 and confirm that the data is 00. Change it to 00 if necessary.3. To check a specific switch, find the switch in Tables 9-1 to 9-3.

• Switches listed in Table 9-1 have their addresses stored in data page 2; the data in an address should bewithin the range listed in the table when the switch is activated. The data should be out of range when theswitch is not activated.

• For switches listed in Tables 9-2 and 9-3:a. Go to the page and address listed for the switch and write down the hexadecimal value at the

address.b. Convert the hexadecimal data to binary (use Table 9-4). The result will be eight bits of “zeros” and

“ones”. (Of the two hexadecimal numbers, the lower one represents binary bits 0 to 3; the upperone represents binary bits 4 to 7.)

Example: To check to PHOTO switch (Table 9-2): 1. Go to page 7, address 0E. 2. Check the value of the data at this address with the switch not pressed (or active), and then

check it with the switch pressed. 3. Using Table 9-4, convert the upper hex number to binary - since we are interested in binary bit

position 5, we need to consider only the upper hex number of the data at address 0E – (bits 0to 3 are determined by the lower hex data number and bits 4 to 7 by the higher data number.)

4. The switch is working if the upper hex number can be converted to binary number 1 when theswitch is pressed and convert to binary number 0 when the switch is released.

10. Power Supply

Chapter 10 - Power SupplyOverviewThis chapter describes the power supply circuit operation and troubleshooting procedures. Circuit descriptionsare limited to what is necessary for troubleshooting.

The power supply consists of the following:

• A switching circuit that selects either external power or battery power as the main power source.• A battery charge circuit.

• A dc-dc power supply control IC that controls and regulates seven switch mode dc-dc converters.

• A bank of six fuses that protect the power supply lines.

• A HI Control IC that controls the power supply with the following functions:

• Turns the dc-dc regulator IC on and off.

• Controls battery charging.

• Switches the power source between external and battery power,

Figure 10-1 is a simplified block diagram of the overall power supply circuits. The power supply components arelocated on the DI-089 board. The ON/OFF control line for the power supply and the battery charge control linesare on the VC-316 board.

InitializationInitialization consists of supplying power to HI CONTROL IC3102 on the VC-316 board so that it can control thepower supply.

1. Power from the battery or the external supply is applied to the to the ALWAYS ON 3v regulator (in IC4502) viasteering diodes D4503. The diodes isolate the battery and external power supplies from each other.

2. A 3V regulator in IC4502 supplies Ever 3V to the Hi Control IC VCC pin, turning it ON.

3. The Hi Control IC can now control the power supply. It has the following control lines:• EXT IN (input) senses when external power is connected to the camcorder.

• BAT IN (input) senses when the battery is connected to the camcorder.

• BAT/XEXT (output) switches the battery to the main power line if external power is not connected.

• CHARGE CONTROL (output) allows the battery to charge at a low rate.

• BAT DATA (bi-directional) communicates with battery MPU. Among other things, it determines the batterycondition.

• DD ON/OFF (output) switches the dc-dc converter regulators on and off. This is the main ON/OFFcontrol line for the camcorder (it does not control Ever 3V).

OTHER FUSES

Battery Charging1. Because lithium ion batteries can be damaged by high charging current, the INIT CHARGE control line will

allow the battery to charge slowly when it has a low remaining charge or is discharged. The battery ischarged via transistor switch Q4603/Q4604, in series with a current limiting resistor and diode.

2. Once the battery has initially charged up, the FAST CHARGE control line will switch on FAST CHARGEtransistor switch Q4601/Q4602, bypassing the INIT CHARGE circuit. This charges the battery at a fast rate,with the charging current limited only by the internal battery circuits.

Power Switching1. If an external power adapter is not connected, the BAT/XEXT sense line is grounded by the DC IN plug. This

is sensed by IC3102 and it forces the FAST CHARGE control line HIGH.

2. The FAST CHARGE transistors switche ON, completing the power path between the battery and the mainpower bus.

40

10. Power Supply

TroubleshootingSince repairs on the VC-316 board are limited to board replacement, initial troubleshooting consists of firstdetermining on which board the problem exists and then troubleshooting the DI board if the problem is there.

Blown Fuses• Blown fuses can be caused by transient surges, shorts or overloads.

• A blown F4603 fuse will prevent the camcorder from turning on: the fuse powers the main power supply dc-dcconverter control IC4502.

• A shorted capstan motor will blow F4603.

Figure 10-3 shows the location of the seven fuses, F4601 ~ F4607, on the DI board. They are all clustered in onelocation.

FIGURE 10-3 - FUSE LOCATIONS

41

10. Power Supply

Shorted Components• The DI board has eight dc-dc switching FET transistors Q4504 through Q4511. A short in any one will blow its

associated supply fuse. Figure 10-4 shows the locations of the switching FETs. Use a DVM to check thetransistors for shorts

11. Z Mechanism

Chapter 11 - Z MechanismOverviewThe DCR-TRV75/80 series of camcorders use the Sony Z100 type tape transport mechanism. Commonlycalled the Z mechanism, it was introduced for the year 2003 model series. Conceptually, it is based on theprevious model J mechanism, although the parts are not interchangeable.

Figures 11-1A and B show the Z mechanism in both closed and open positions.

11. Z Mechanism

In addition to the tools listed on the previous page, the following items are also required (not shown in the diagram):• Standard 100 MHz oscilloscope

• DVM

• Temperature adjustable soldering iron with a fine point tip

Servicing MechanismParts are available for many of the mechanism components. The mechanism is also available as a completeassembly that includes the loading basket assembly. The mechanism part number is A-7095-393-A.

v Complete mechanisms are supplied without drums. Use the old drum unless it is defective.

Drum• The drum is easily replaced. It is secured by three easily accessible screws.

• Drum heads can be cleaned using standard head cleaning procedures.

Operating the Mechanism• The mechanism can be cycled with the Mode Selector II jig. The jig also allows you to check the operation and

timing of the mode position switch.

• For simple load/unload functions, the mechanism can also be cycled by applying about 4.5 volts to the loadingmotor from an external power supply; the motor terminals are easily accessible. Set the current limiting onthe power supply to 100ma to prevent the motor from overheating if the mechanism is jammed.

Two additional items are required for the Mode Selector II jig to function with the Z mechanism:

1. A ROM chip upgrade for the Mode Selector II jig to make the jig electrically compatible with the Z mechanism.

2. Mode selector conversion (interface) board, item J-12. This adapts the mode selector jig box to fit the Zmechanism cabling.

12. Service Information

Chapter 12 - Service InformationEEPROM SwapWhen replacing VC boards, in many situations the data in the old board cannot be uploaded and saved to acomputer prior to removing the defective VC board. In such cases, the old and new EEPROMs should beswapped before inserting the new board into the camcorder. This will assure that the new board has all of theoriginal camcorder data, reducing or at times even eliminating the need to realign the camcorder.

• A more comprehensive level of diagnosing with error codes: With RADAR W, the technician can see theactive error code plus the error codes from two previous error instances.

• The number of head hours on the drum: Be sure to reset the value when replacing the drum.

• The number of mechanism ejects: Reset this value when replacing the mechanism.

• Days from the first Power ON occurrence: This may assist the technician in the event of questionable warranteeeligibility. This value should NOT be reset.

RADAR W CodesBesides being an invaluable aid in camcorder alignment, RADAR W can also provide a considerable amount ofinformation regarding the camcorder. Some of the items are highlighted in Figure 12-5.
