NOTICE: Comply with all cautions and safety-related noteslocated on or inside the cover case and on the chassis or plasmamodule.WARNING: Since the chassis of the AVC unit and Plasma Panelunit is connected to both sides of the AC power supply duringoperation, whenever the receiver is plugged in, service shouldnot be attempted by anyone unfamiliar with the precautionsnecessary when working on this type of receiver.

1. When service is required, an isolation transformer should beinserted between power line and the receiver before anyservice is performed on a HOT chassis receiver.

2. When replacing a chassis in the receiver, all the protectivedevices must be put back in place, such as barriers, non-metallic knobs, insulating cover-shields, and isolationresistors, capacitors, etc.

3. When service is required, observe the original lead dress.

4. Always use manufacturers replacement components. Criticalcomponents as indicated on the circuit diagram should not bereplaced by another manufacturers. Furthermore, where ashort circuit has occurred, replace those components thatindicate evidence of over heating.

5. Before returning a serviced receiver to the customer, theservice technician must thoroughly test the unit to be certainthat it is completely safe to operate without danger of electricalshock, and be sure that no protective device built into thereceiver by the manufacturer has become defective, orinadvertently defeated during servicing.

Therefore, the following checks should be performed for thecontinued protection of the customer and service technician.

Leakage Current Cold CheckWith the AC plug removed from the 120V AC 60Hz source,place a jumper across Line 1 and Line 2 of the three plugprongs, do not connect with the third prong, which is physicalground.Using an insulation tester (DC500V), connect one of its leadsto the AC plug jumper and touch with the other lead eachexposed metal part (antennas, screwheads, metal overlays,control shafts, etc.), particularly any exposed metal parthaving a return path to the chassis should have a resistorreading over 4M. Any resistance value below this rangeindicates an abnormality which requires corrective action. Anexposed metal part not having a return path to the chassis willindicate an open circuit.

SAFETY PRECAUTIONSLeakage Current Hot Check

This check must be done considering the AVC or the PDPmonitor as one instrument each.With any of the instruments completely reassembled (beingthe instrument either the AVC center or the PDP monitor), plugthe AC line cord directly into a 120V AC outlet. (Do not use anisolation transformer during this test.) Use a leakage currenttester or a metering system that complies with the AmericanNational Standards Institute (ANSI) C101.0 Leakage Currentfor Appliances. In the case of the PDP monitor set the ACswitch first in the ON position and then in the OFF position,measure from across Line 1 and Line 2 of the three plugprongs, do not connect with the third prong, which is physicalground, to all exposed metal parts of the instrument(antennas, handle bracket, metal cabinet, screw heads,metallic overlays, control shafts, etc.), especially any exposedmetal parts that offer an electrical return path to the chassis.Any current measured must not exceed 0.5 MIU. Reverse theinstrument power cord plug in the outlet and repeat test.

Remember: Safety First.

General Servicing Guidelines1. Always unplug the instrument AC power cord from the AC

power source before: a. Removing or reinstalling any component, circuit

board, module, or any other instrument assembly.

b. Disconnecting or reconnecting any instrumentelectrical plug or other electrical connection.

c. Connecting a test substitute in parallel with anelectrolytic capacitor in the instrument.

CAUTION: A wrong part substitution or incorrectpolarity installation of electrolyticcapacitors may result in an explosionhazard.

2. Do not spray chemicals on or near this instrument or anyof its assemblies.

3. Unless specified otherwise in these service data, cleanelectrical contacts by applying the following mixture to thecontacts with a pipe cleaner, cotton-tipped stick orcomparable nonabrasive applicator: 10% (by volume)Acetone and 90% (by volume) isopropyl alcohol (90%-99% strength). CAUTION: This is a flammable mixture. Unless

specified otherwise in these service data,lubrication of contacts is not required.

4. Do not defeat any plug/socket of voltage interlocks withwhich instruments covered by this service data might beequipped.

5. Do not apply AC power to this instrument and/or any of itselectrical assemblies unless all solid-state device heat-sinks are correctly installed.

6. Always connect the test instrument ground lead to theappropriate instrument chassis ground before connectingthe test instrument positive lead. Always remove the testinstrument ground lead last.

7. Use with this instrument only the test fixtures specified inthis service data.CAUTION: Do not connect the test fixture ground strap

to any heatsink in this instrument.

Electrostatically Sensitive (ES) DevicesSome semiconductor (solid state) devices can be damagedeasily by static electricity. Such components commonly arecalled Electrostatically Sensitive (ES) Devices. Examples oftypical ES devices are integrated circuits and some field-effect transistors and semiconductor chip components. Thefollowing techniques should be used to help reduce theincidence of component damage caused by static electricity.

1. Immediately before handling any semiconductorcomponent or semiconductor-equipped assembly, drainoff any electrostatic charge on your body by touching aknown earth ground. Alternatively, obtain and wear acommercially available discharging wrist strap device,which should be removed for potential shock reasonsprior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ESdevices, place the assembly on a conductive surfacesuch as aluminum foil, to prevent electrostatic chargebuildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder ordesolder ES devices.

4. Use only an anti-static type solder removal device. Somesolder removal devices not classified as anti-static cangenerate electrical charges sufficient to damage ESdevice.

5. Do not use freon-propelled chemicals. These cangenerate electrical charges sufficient to damage ESdevices.

6. Do not remove a replacement ES device from itsprotective package until immediately before you areready to install it. (Most replacement ES devices arepackaged with leads electrically shorted together byconductive foam, aluminum foil or comparable conductivematerial.)

7. Immediately before removing the protective material fromthe leads of a replacement ES device, touch theprotective material to the chassis or circuit assembly intowhich the device will be installed.CAUTION: Be sure no power is applied to the chassis or

circuit, and observe all other safetyprecautions.

8. Minimize bodily motions when handling unpackagedreplacement ES devices. (Otherwise harmless motionsuch as the brushing together of your clothes fabric or thelifting of your foot from a carpeted floor can generatestatic electricity sufficient to damage an ES device.)

General Soldering Guidelines1. Use a grounded-tip, low-wattage soldering iron and

appropriate tip size and shape that will maintain tiptemperature within the range 500F to 600F.

2. Use an appropriate gauge of resin-core solder composedof 60 parts tin/40 parts lead.

3. Keep the soldering iron tip clean and well-tinned.

4. Thoroughly clean the surfaces to be soldered. Use asmall wire-bristle (0.5 inch or 1.25 cm) brush with a metalhandle. Do not use freon-propelled spray-on cleaners.

5. Use the following desoldering technique.a. Allow the soldering iron tip to reach normal

temperature (500F to 600F).b. Heat the component lead until the solder melts.

Quickly draw away the melted solder with an anti-static, suction-type solder removal device or withsolder braid.CAUTION: Work quickly to avoid overheating the

circuit board printed foil.

6. Use the following soldering technique.a. Allow the soldering iron tip to reach normal

temperature (500F to 600F).b. First, hold the soldering iron tip and solder strand

against the component lead until the solder melts.

c. Quickly move the soldering iron tip to the junction ofthe component lead and the printed circuit foil, andhold it there only until the solder flows onto andaround both the component lead and the foil.CAUTION: Work quickly to avoid overheating the

circuit board printed foil or components.

d. Closely inspect the solder area and remove anyexcess or splashed solder with a small wire-bristlebrush.

Removal1. Desolder and straighten each IC lead in one operation by

gently prying up on the lead with the soldering iron tip asthe solder melts.

2. Draw away the melted solder with an anti-static suction-type solder removal device (or with solder braid) beforeremoving the IC.

Replacement1. Carefully insert the replacement IC in the circuit board.

2. Carefully bend each IC lead against the circuit foil padand solder it.

3. Clean the soldered areas with a small wire-bristle brush.(It is not necessary to reapply acrylic coating to areas.)

Small-signal Discrete Transistor Removal/Replacement1. Remove the defective transistor by clipping its leads as

close as possible to the component body.

2. Bend into a U shape the end of each of the three leadsremaining on the circuit board.

3. Bend into a U shape the replacement transistor leads.

4. Connect the replacement transistor leads to thecorresponding leads extending from the circuit board andcrimp the U with long nose pliers to insure metal tometal contact, then solder each connection.

Power Output Transistor Devices Removal/Replacements1. Heat and remove all solder from around the transistor

leads.

2. Remove the heatsink mounting screw (if so equipped).3. Carefully remove the transistor from the circuit board.

4. Insert new transistor in circuit board.

5. Solder each transistor lead, and clip off excess lead.

6. Replace heatsink.

Diode Removal/Replacement1. Remove defective diode by clipping its leads as close as

possible to diode body.

2. Bend the two remaining leads perpendicularly to thecircuit board.

3. Observing diode polarity, wrap each lead of the newdiode around the corresponding lead on the circuit board.

4. Securely crimp each connection and solder it.

5. Inspect (on the circuit board copper side) the solder jointsof the two original leads. If they are not shiny, reheatthem and, if necessary, apply additional solder.

Use Soldering Iron to Pry Leads

IC Removal/ReplacementSome Hitachi unitized chassis circuit boards have slottedholes (oblong) through which the IC leads are inserted andthen bent flat against the circuit foil. When holes are theslotted type, the following technique should be used toremove and replace the IC. When working with boards usingthe familiar round hole, use the standard technique asoutlined in paragraphs 5 and 6 above.

6PLC1/AVC5-UB

Fuses and Conventional Resistor Removal/Replacement1. Clip each fuse or resistor lead at top of circuit board

hollow stake.

2. Securely crimp leads of replacement component aroundstake 1/8 inch from top.

3. Solder the connections.CAUTION: Maintain original spacing between the

replaced component and adjacentcomponents and the circuit board, toprevent excessive componenttemperatures.

Circuit Board Foil RepairExcessive heat applied to the copper foil of any printedcircuit board will weaken the adhesive that bonds the foil tothe circuit board, causing the foil to separate from, or lift-off, the board. The following guidelines and proceduresshould be followed whenever this condition is encountered.

In Critical Copper Pattern AreasHigh component/copper pattern density and/or specialvoltage/current characteristics make the spacing andintegrity of copper pattern in some circuit board areas morecritical than in others. The circuit foil in these areas isdesignated as Critical Copper Pattern. Because CriticalCopper Pattern requires special soldering techniques toensure the maintenance of reliability and safety standards,contact your Hitachi personnel.

At IC ConnectionsTo repair defective copper pattern at IC connections, use thefollowing procedure to install a jumper wire on the copperpattern side of the circuit board. (Use this technique only onIC connections.)1. Carefully remove the damaged copper pattern with a

sharp knife. (Remove only as much copper as absolutelynecessary.)

2. Carefully scratch away the solder resist and acryliccoating (if used) from the end of the remaining copperpattern.

3. Bend a small U in one end of a small-gauge jumper wireand carefully crimp it around the IC pin. Solder the ICconnection.

4. Route the jumper wire along the path of the cut-awaycopper pattern and let it overlap the previously scrapedend of the good copper pattern. Solder the overlappedarea, and clip off any excess jumper wire.

1. Remove the defective copper pattern with a sharp knife.Remove at least 1/4 inch of copper, to ensure hazardouscondition will not exist if the jumper wire opens.

2. Trace along the copper pattern from both wire sides ofthe pattern break and locate the nearest componentdirectly connected to the affected copper pattern.

3. Connect insulated 20-gauge jumper wire from thenearest component on one side of the pattern break tothe lead of the nearest component on the other side.Carefully crimp and solder the connections.CAUTION: Be sure the insulated jumper wire is

dressed so that it does not touchcomponents or sharp edges.

MH DIODE RESISTOR

Leadless Chip Components(surface mount)Chip components must be replaced with identicalchips due to critical foil track spacing. There are noholes in the board to mount standard transistors ordiodes. Some chip capacitor or resistor board solderpads may have holes through the board, however thehole diameter limits standard resistor replacement to1/8 watt. Standard capacitors may also be limited forthe same reason. It is recommended that identicalchip components be used. .Chip resistors have a three digit numerical resistancecode -1st and 2nd significant digits and a multiplier.Example: 162 = 1600 or 1.6K resistor, 0 = 0(jumper).Chip capacitors generally do not have the valueindicated on the capacitor. The color of the componentindicates the general range of the capacitance.Chip transistors are identified by a two letter code. Thefirst letter indicates the type and the second letter, thegrade of transistor.Chip diodes have a two letter identification code asper the code chart and are a dual diode pack witheithercommon anode or common cathode. Check the partslist for correct diode number.Component Removal1. Use solder wick to remove solder from component

end caps or terminals.2. Without pulling up, carefully twist the component

with tweezers to break the adhesive.3. Do not reuse removed leadless or chip

components since they are subject to stressfracture during removal .

Chip Component Installation1. Put a small amount of solder on the board

soldering pads.2. Hold the chip component against the soldering

pads with tweezers or with a miniature alligatorclip and apply heat to the pad area with a 30 wattiron until solder flows. Do not apply heat for morethan 3 seconds

How to Replace Flat-lCRequired Tools Soldering iron iron wire or small awl De-solder braids Magnifier1. Remove the solder from all of the pins of a Flat-lC

by using a de-solder braid.

2. Put the iron wire under the pins of the Flat-lC andpull it in the direction indicated while heating thepins using a soldering iron. A small awl can beused instead of the iron wire.

3. Remove the solder from all of the pads of theFiat-lC by using a de-solder braid.

4. Position the new Flat-lC in place (apply the pins ofthe Flat-lC to the soldering pads where the pinsneed to be soldered). Properlydetermine the positions of thesoldering pads and pins bycorrectly aligning the polaritysymbol.

6. Check with a magnifier for solder bridge betweenthe pins or for dry joint between pins and solderingpads. To remove a solder bridge, use a de-solderbraid as shown in the figure below.

NOTE: These components are affixed with glue. Be careful not to break or damage any foil under thecomponent or at the pins of the ICs when removing. Usually applying heat to the component for a shorttime while twisting with tweezers will break the component loose.

3. Communication Protocol3.1- Terminal Mode (Communication between television and external PC)

- When the RS232C mode is set from Off to On by the television OSD menu andthe TXD2 and RXD2 serial communication lines are switched to AV control, thetelevision can communicate with an external PC.

Table 3.2.1 Terminal Mode Control

(1) External PC can turn terminal mode On and Off.(2) Communication is prohibited when terminal mode is Off.(3) When terminal mode is on, Front Keys and Remote do not operate. The only button that will

operate is main power.(4) When TV set is turned Off and On, terminal mode remains in its current state(5) Factory Setting: Terminal Mode is Off and AV Control Mode is Off.(6) The television will always respond when an attempt to turn terminal mode on or off is made

with either an ACK or a NAK.(7) In the following cases, even if the check box of menu is checked, Terminal mode cannot be

turned on.- Adjust mode- While Event Timer and Timer Recording- While Auto CH scan operates- While Magic Focus operates- While upgrade operates

(8) Write function in terminal mode will write data to the EEPROM in the same manner as whenunit is operated in Normal Mode through the OSD.

(9) For OSD functionality in terminal mode, see table 5.

3.2- Command Summary (Sending and Receiving Data)3.2.1- Data received by Television TV will accept data from the PC when it is properly formatted as shown in table 3.2.1.1 only

when the Terminal Mode is ON. The command length is 12 bytes with a start and stop byte. Therefore total command strings

are 14 bytes The command consists of 6 Hex codes from 1st to 6th as shown below. (Total 12 bytes) All command strings should be described in character code and then converted to Hex Code. Table 3.2.1.2 shows the 3 types of command formats All commands are classified into these 3 types of command by the 1st and 2nd command byte.

If the Terminal Mode is turned on while the Sleep Timer is active and unit is powered off bythe controller, the time values in the Sleep Timer will be cleared.

The Event Timer/ Timer Rec. will not operate when the unit is Terminal Mode On. If the Terminal Mode is activated when the Auto Link Setting is in Stand-By, The Auto Link

operation will be cancelled. The Urgent Broadcast Signal will take precedence when Terminal Mode is on with the

CableCARD installed. The Magic Timer function is disabled when Terminal Mode is On.

(2) Other Terminal Control Considerations Terminal Mode will remain On when you turn the power supply Off or On. If the TV is unplugged at the wall outlet, the Terminal Mode will turn Off. If the TV is turned off in normal mode and the Terminal On command is sent, the unit can be

turned on via RS232C. The commands executed in Terminal mode should be executed and displayed after exiting

Terminal Mode.(3) Command Execution

1- The time delay between 1 byte characters in a command string is 99mS. Any delaylonger than 100mS will be cancelled and the unit will respond with a NACK (16H).

2- When transmitting command strings, an ACK or NAK should be sent by the TV. However,this will not be the case when commands are re-executed or the command does notexecute.

3- The framing delay between continuos commands is 32mS.4- When communicating with the unit in Terminal Mode, the unit must respond with either

an ACK or an NAK before sending it another command. Failure to do so will result incommands that are not executed.

5- Please note that when the Power on command is sent to the unit, it will be necessary towait 12 seconds before sending any other command.

4. Command String Development Information

4.1- To assist with developing command strings, the table below shows a Hex characterconversion chart

Table 4.1.1 Hex Character Conversion Chart

4.2 - An example of the proper coding technique is demonstrated below for the Power On Command.

Hex Character Set: 6E: Power Function 00: Write Function (Note- A 01 would indicate a read function)

00: 3rd (Upper byte-Function) 00: 4th (Lower byte-Function)

00: 5th (Upper byte-Data) 01: 6th (Lower byte- Data

Hex Coded Data: 364530303030303030303031Note- an STX (02-Hex) would be added at the start of the string and ETX (03-Hex) would beadded at the end of the string to create a complete command.

INTRODUCTION

The 32HDL51M are LCD Television sets; They are constituted by the combination of two main parts, an AUDIO VIDEO CONTROLCenter, and the LCD Display monitor.Each part has a model name and a chassis name:

The AVC center is a box that controls most of the user functions of the complete TV set and conditions the signal before it arrives to themonitors.

The 32 monitors contain the displaying device, which is the LCD display panel module, and the driving circuitry, which receives thesignal from the AVC center and after processing, delivers the image to the display module.

This HITACHI Service Manual is intended for the qualified service personnel and it contains the necessary information fortroubleshooting the Plasma television set in case of malfunction.
