SAFETY PRECAUTIONS

WARNING: The following precautions should be observed.

1. Do not install, remove, or handle the picture tubę in any manner unless shatter proof goggles are worn. People not so equipped should be kept away while picture tubes are handled. Keep the picture tubę away from the body while handling.

2. When service is required, an isolation transformer should be inserted between power linę and the receiver before any service is performed on the chassis.

3. When replacing the chassis in the cabinet, ensure all the protective devices are put back in place, such as barriers, non-metallic knobs, adjustment or compartment covers or shields, isolation resistors/capacitors, etc.

4. When service is required, observe the original lead dressing. Extra precaution should be taken to assure correct lead dressing in the high voltage circuitry area. Particularly notę the R.G.B. lead dressing. Ensure they are dressed well away from the horizontal scan and F.B.T. circuitry.

5. Always use the manufacturer's replacement component. Always replace original spacers and maintain lead lengths. Especially critical components are indicated thus A on the parts list and should not be replaced by other makes. Furthermore, where a short Circuit has occurred, replace those components that indicate evidence of overheating.

6. Before returning a serviced receiver to the customer, the service technician must thoroughly test the unit to be certain that it is completely safe to operate without danger of electrical shock, and be surę that no protective device built into the instrument by the manufacturer has become defective, or inadvertently damaged during servicing.

Therefore, the following checks are recom-mended for the continued protection of the customers and service technicians.

INSULATION

Insulation resistance should not be less than 10M£2 at 500V DC between the mains poles and any accessible metal parts.

Also, no flashover or breakdown should occur during the dielectric strength test, applying 3kV AC or 4.25kV DC for two seconds between the main poles and accessible metal parts.

HIGH VOLTAGE

High voltage should always be kept at the rated value of the chassis and no higher. Operating at higher voltages may cause a failure of the picture tubę or high voltage supply, and also, under certain circumstances could produce X-radiation moderately in excess of design levels. The high voltage must not, under any circumstances, exceed 27kV on the chassis.

X-RADIATIOI\l

TUBES: The primary source of X-radiation in this receiver is the picture tubę. The tubę utilised for the above mentioned function in this chassis is specially constructed to limit X-radiation.

For continued X-radiation protection, replace tubę with the same type as the original HITACHI approved type.

PRODUCT SAFETY NOTICE

Many electrical and mechanical parts in HITACHI television receivers have special safety related characteristics. These characteristics are often not evident from visual inspection, nor can the protection afforded by them necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified by marking with a A on the schematics and replacement parts list in this Service Manuał. The use of a substitute replacement component which does not have the same safety characteristics as the HITACHI recommended replacement one, shown in the parts list in this Service Manuał, may create electrical shock, fire, X-radiation, or other hazards.

Product Safety is continuously under review, and new instructions are issued from time to time. For the latest information, always consult the current HITACHI Service Manuał. A subscription to, or additional copies of HITACHI Service Manuals, may be obtained at a nominał charge from your HITACHI SALES CORPORATION.

TUBĘ DISCHARGE

The linę output stage can develop voltages in excess of 25kV; if the E.H.T. cap is required to be removed, discharge the anodę cap to chassis via a high value resistor, prior to its removal from the tubę.

CIRCUIT DESCRIPTION

Tuner and I.F. Stages:

The tuner used on this chassis, is powered by the +12v supply, and covers VHF, UHF, and S bands.

When tuning procedurę is in operation, the mark/space ratio output from pin 1 of IC001 changes. This is applied to the base of Q003, and the resultant voltage at the collector is filtered by the network C031, R041/C033, R042/C034, then applied via R043 to the VT terminal of the tuner.

Signal recognition is performed by IC201 in conjunction with IC1001, and is explained later in the tuning and control Circuit description.

Band switching is performed by IC003 type LA7910, which is powered at pin 6 from the 110v supply. This IC consists basically of four switches, which are connected to the + 12v supply applied to pin 9. The selection of these switches is determined by IC001. "High" or "Low" outputs are obtained from. pins 6 and 7 of IC001, then applied to pins 3 and 4 of IC003. The "High" or "Low" State of these two pins determine which of the internal switches of IC003 are selected, and therefore which of the tuner terminals BU, BL, or BH has a +12v applied to it.

The I.F. output from the tuner is applied to amplifier Q204, then input to pin 1 of SAW filter CP201.

Sound I.F. stages:

The sound stages consist of IC4001, which is basically a demodulator, and IC401, which is the output amplifier.

The I.F. signal at the collector of Q204, is fed via filter CP201, and input to IC201 at pins 9 and 10.

The composite signal output from pin 20 of IC201 is applied to pin 13 of IC4001 via the 6MHz filter MF4002. Demodulation is then performed by the IC, in conjunction with L4002 and R401 5 connected between pins 8 and 9. The demodulated sound is output from pin 20 of IC4001.

It is then applied to IC401 pin 3, amplified, and output to the speaker from pin 7.

Volume control is performed by the DC voltage applied to pin 1 of IC401, which is obtained via R018/R020. This voltage level is governed by the output from IC001 pin 5. Under no signal eonditions, or when "SEARCH" routine is initiated, pin 14 of IC201 (mute) will go "Low". This is then applied to pin 1 of IC4001 via D4001, thus preventing audio output for as long as the "Low" exists.

An audio output is also available from pin 2 of IC4001. This is fed via C4012 to pins 1 and 3 of the 21 pin peri-socket, and can then be output to external equipment if desired.

Audio signals from external equipment can be input to pins 2 and 6 of the 21 pin peri-socket; they are then applied to pin 4 of IC4001.

When using this facility, a "High" is applied to pin 3 of IC4001 from IC001, thereby changing the internal switching circuitry of the IC. The audio signal input at pin 4, will then emerge from pin 20 for amplification by IC401.

(How the "High" switching voltage is obtained, will be explained later in the Tuning and Control Circuit description).

Vision I.F. Stages:

The I.F. signal input to CP201 pin 1, is output from pins 4 and 5, then input to IC201 at pins 9 and 10. These pins supply an internal amplifier consisting of three stages, whose gain is controlled by the AGC Circuit. The response speed of this internal AGC stage is determined by the external components connected between pins 2 and 6 of the IC.

The output from the I.F. amplifier is then fed to the video detector circuitry. The picture carrier is limited and phase shifted by the tank circuitry of L205 etc., connected between pins 23 and 24 of the IC. This produces a reference frequency, which is then utilised for synchronous video detection.

An RF AGC voltage is madę available at pin 6 of IC201, the starting level of which is determined by the voltage applied to pin 2, which in turn is fixed by the setting of VR201. This AGC voltage is then fed to the tuner via R232, and Controls its gain accordingly.

The composite video emerging from pin 20 of IC201, is fed via buffer Q290 and the 6MHz trap MF201, then input as the video signal to pin 16. After further Processing, it finally emerges at pin 15 of IC201.

Luminance Circuitry

The composite video signal output from pin 15 of IC201 is applied to the picture enhancement circuitry of Q301/Q302, then input to pin 11 of IC503 via the delay linę DL301. This signal is amplified and added to the RGB matrix circuits of the IC via an internal black level clamping Circuit. It is also internally applied to a brightness control Circuit, a contrast control Circuit, and a blanking Circuit. The luminance finally emerges with the RGB signals from pins 19, 20 and 1. These signals are then applied to the video output transistors Q801, Q802 and Q803 on the CRT base.

The voltages to control the contrast and brightness levels are output from pins 2 and 3 of IC001, and applied to pins 16 and 17 of IC503.

An automatic beam current Circuit is employed on this chassis.

Should the beam current start to rise, the voltage at pin 4 of the flyback transformer will fali. This fali is applied to the cathode of D706, then via R707 to pin 16 of IC503, thus reducing the contrast level. As pin 16 and 1 7 are internally connected, the brightness is also reduced at the same time, therefore in this way, the rise in beam current is stabilized.

The video signal from MF201 is also applied to the base of emitter follower Q202. It is then fed to pin 19 of the 21 pin peri-socket via R210, and can then be output to external equipment if desired.

Video inputs from external equipment connected to the 21 pin peri-socket, are fed from pin 20 to IC201 pin 13. When the external signal modę is selected, a "High" is applied to pin 18 of IC201. This "High" is also applied to the base of Q206, turning it on, thus applying a "Low" to pin 17 of the IC. These "High" and "Low" inputs cause a change in the internal switching network, so that only the video input at pin 13 of IC201 is output from pin 15 for further processing.

Chrominance Circuitry:

The composite video signal from pin 1 5 of IC201 is fed via C501 and the band — pass Circuit R501, L501, C502, then applied to pin 15 of 1C501.

The demodulated colour signals are output from pins 1 and 3 of IC501 as the R-Y and B-Y signals, then fed to pins 14 and 16 of IC502 which is a switch capacitor delay linę. These inputs at pins 14 and 16 are clamped, then fed via a buffer stage to internal delay lines, which are driven by a clock signal of 3MHz to obtain a delay period of 64u Seconds. This internal clock is generated from a 6MHz voltage controlled oscillator, and linę locked by the sandcastle pulse input at pin 5.

The undelayed signals are then added to the delayed signals, and the resulting R-Y and B-Y signals are output from pins 11 and 12 via an internal buffer stage.

These outputs are then fed to IC503 at pins 14 and 15. This IC contains clamping circuits, and a DC colour saturation control which is set by the voltage applied to pin 12 from IC001. The signals are then applied to a MATRIX Circuit, and finally emerge from pins 19, 20 and 1 as the Red, Green and Blue signals.

Deflection Circuits:

The deflection circuitry of IC201 contains a sync. separator stage, horizontal oscillator/output stages, and a vertical count-down and output stage.

Horizontal Stage

The composite video signal output from pin 15 of IC201 is input to the sync. separator stage at pin 28 via C221, R219.

The phase detector stage is provided with a sawtooth waveform, which is generated from the linę pulse input to pin 31. The phase detector will then compare this sawtooth waveform to the sync. pulse, and any freąuency drift will cause a corrective output to be applied to the horizontal oscillator, thereby maintaining the desired phase relationship.

The components connected to pin 27 of IC201 form a filter network for the phase detector, and VR202 connected to pin 26 via R215, sets the free running oscillator frequency.

The horizontal output emerges at pin 29, and is then applied to the base of linę drive transistor Q701. T701 couples the output of Q701 to the linę output transistor Q702. Both these transistors are powered by the H.T. supply voltage.

A linę pulse available at pin 1 of the flyback transformer is rectified by D701, smoothed by C709, and provides approximately 180v to drive the C.R.T. base output transistors Q801, Q802, and Q803.

Under certain fault conditions, i.e. increased H.T. supply, Iow linę oscillator frequency, or reduced value of the tuning capacitor C706, an excess of E.H.T. could be developed. To prevent this happening, the rectified voltage of D701 is fed via potential divider R722, R733, to the cathode of ZD702. Should the E.H.T. rise excessively, the threshold of the zener will be exceeded, and a voltage will be applied to the gate of Q703 via R727, turning it on. This effectively applies a "Low" to the cathode of ZD003, and as a result Q952 is turned off. Consequently, a “High" is applied to pin 2 of IC903 via R959, and as a result the IC will shut down. The +1 2v supplying IC201 is then removed, thereby preventing further E.H.T. generation.

Excessive beam current can also occur under certain fault conditions, so this is prevented in the following manner.

The voltage at R720 is smoothed by R719/C705, then applied to the cathode of ZD701. Should the beam current rise drastically, the threshold of the zener will be exceeded, and a voltage will be applied to the gate of Q703. This will prevent further E.H.T. generation as described earlier, and therefore limits the rise in beam current.

A supply of +25v is required for IC601. This is obtained from pin 6 of the flyback transformer, rectified by D702, smoothed by C710 and protected by fusible resistor R724.

Vertical Stages:

The internal vertical sync. of IC201 is fed to a triggered vertical divider stage. This stage counts down the horizontal frequency to obtain the vertical frequency, thereby eliminating the need for a conventional oscillator Circuit. This also has the advantage that no external frequency control is required.

C206 at pin 3 of the IC is used for ramp generation, and produces the required sawtooth output.

The vertical output from pin 4 of IC201 is applied to pin 4 of IC601 via R205/R602. The components D601 and C606 determine the flyback generation time, and the vertical output to drive the deflection coils is madę available from pin 2.

The deflection current that occurs at the junction of R608/R610, is added to the feedback from R605/C609 etc, and the result is applied to pin 5 of IC201. This feedback Controls linearity and height. The values of R605/C609 determine the linearity, whilst VR601 sets the height.

Power Supply Circuit:

The AC input is rectified by D901 - 04 and supplies approximately 300v to pin 3 of IC901. Current flows through R901, R909, and when the voltage between pins 2 and 4 of IC901 reaches approximately 0.7v, then the internal power transistor of IC901 turns on.

Secondary vo!tages are then induced in T901, and a feedback voltage is obtained via D905, L903 etc. This is applied to pin 2 of IC901 and maintains the operating conditions. This circuitry self oscillates at a frequency determined by the inductance of the transformer, the AC mains voltage and load conditions etc.

The secondary voltage in the S1 — S2 winding is rectified by D951 to produce the H.T. of 110v, which is smoothed by C952. The S3 - S4 winding produces 1 5v via D952, and this is smoothed by C954.

Q951 stage Controls H.T. regulation. The base of Q951 is set to a pre-determined level by the resistor network R952, VR951, and R951.

Should the H.T. rise, the emitter voltage of Q951 will become morę positive, and this difference is amplified by the transistor and applied to opto-coupler IC902. This produces an output from pin 5, which is then applied to pin 1 of IC901. This pin feeds an internal transistor network which Controls the on time of the power transistor.

Therefore, in this way the H.T. is regulated and maintained at a constant level,

ZD952 offers protection to the H.T. circuits. Should the voltage level rise excessively it will become short circuited.

When the standby modę is selected, pins 6 and 7 of IC001 will go “Low". Consequently, the base of Q952 goes "Low", and the transistor turns off. Pin 2 of IC903 then becomes "High" via R959, and as a result the +12v output at pin 5 disappears. This shuts down the E.H.T. circuitry for as long as the standby condition exists.

Tuning and Control Circuitry:

The remote contro! receiving unit U001, contains an infra red amplifier type GP1U721Q. This is powered by the + 5v supply, which is obtained from the +15v supply via R957/R097, and stabilized by ZD001.

The output from pin 1 of this U001 is applied to pin 35 of IC001.

This IC type TMP47C634N - R104, performs channel selection, UP/DOWN analogue control, on—screen display, search tuning, teletext control, and Controls input and output selection to and from the peri - socket. IC002 type TC89102 is the memory IC, which Stores the data relating to all the above functions, then transfers that information to IC001 when required. Both these !Cs are powered by the + 5v supply.

X001, C026 and C027 supply IC001 with a basie clock frequency which Controls all operating modę requirements.

When the TV is first switched on, IC001 must be initially reset, and this is achieved by Q002 stage. As the + 5v supply begins to rise from switch on, C030 charges, and as a result Q002 is turned on, thus pulling its collector "Low". This "Low" is then applied to pin 33 of IC001, thus resetting the IC. Once the + 5v has been reached and maintained, C030 ceases its charging action, and Q002 is turned off.

The "Low" is then removed from pin 33 of !C001, releasing the reset condition.

Once the search routine has been initiated, and a signal has been located, pin 14 of IC201 will become "High”. This is applied to pin 36 of IC001, and informs the IC that a signal is present. The search routine then stops, and the IC monitors the AFC signal present at pin 9 to obtain the optimum signal.

Contrast, colour, brightness, and volume levels can be adjusted from the remote control handset (the volume can also be adjusted by + and — buttons on the front of the TV), and result in DC level changes from pins 2 - 5 of IC001, which are then fed to the relevant pins of IC503 and IC4001.

Pins 11 - 1 5 form the in and out matrix for the front control operations.

When in teletext modę, pins 8 and 1 2 supply the clock and data outputs.

Should external equipment be connected to the peri — socket and turned on, a "High” is applied to D033. The diodę will then become forward biased, and applies this "High" to pin 34 of IC001. This results in a "High” output from pin 37, which is applied to IC201 pin 18, and also to Q206 base. This changes the switching modę of IC201 so that video signals from external equipment can be processed. The "High" from IC001 pin 37 is also applied to pin 3 of IC4001 to change the switching network of that IC, so that audio inputs from external equipment are accepted for Processing.

If the external equipment does not have an equivalent 21 pin connector, the handset button Drwili need to be pressed. This instructs 1C001 to create a "High" output from pin 37 to achieve the necessary switching, as explained earlier.

The red, green and blue on-screen display signals are output from pins 22, 23, and 24 of 1C001. The components L016, C024, and C025, on pins 28 and 29, determine the display oscillator frequency. The horizontal and vertical inputs at pins 26 and 27 determine the actual position of the on-screen display.

When a command requiring an on —screen display is received by IC001, a "High” will be output from pin 25. This is applied to pin 7 of IC503, and blanks out a portion of the picture. The on —screen display information is then inserted into this portion, thus resulting in a elear display.

When the ALARM modę has been set, and the amount of time input has elapsed, an output is obtained from pin 38 of IC001. This is then applied to pin 3 of IC401 via R001, C001, and R085, thereby causing a "Bleep" sound to be heard.

Should the OFF timer modę be set, and the amount of time input has elapsed, pins 6 and 7 of IC001 output a "Low". This removes the supply to the base of Q952, and as a result the 12v output of IC903 disappears, thereby placing the TV into its standby modę of operation as explained previously.

When the ON time has been estimated and set, the TV must be placed into its standby modę. As an indication that the standby modę is only temporary, pin 18 of IC001 is taken "High" and "Low" alternately, causing D001 to flash on and off. When the entered time has elapsed, the TV will return to its normal operational modę, and the "Low" outputs are removed.

Teletext Circuit (A003 Module):

The two main ICs which control the teletext operations are IC2201 type CF72303, and IC2202 type CF70095.

IC2201 is the data slicer, whilst IC2202 is the decoder, character generator and controller, which also contains a 1 k bite RAM.

The text data is applied to pin 17 of IC2202, and RGB text signals are output from pins 20, 22, and 23 of IC2002, then input to IC503 at pins 8, 9, and 10.

During teletext modę a "High" is output from pin 19 of IC2002. This is also applied to IC503 at pin 7, therefore only allowing the teletext data input at pins 8, 9, and 10, to be output from pins 1,19, and 20 for display.

IC2203, type PST529C, performs the reset operation for IC2202 when TV is first switched on, or brought out of standby. Until the voltage at pin 1 of IC2203 reaches 4v5, pin 3 remains "Low". This "Low" is applied to pin 5 of IC2002 and initiates the reset condition. Once pin 1 of IC2003 exceeds 4v5, pin 3 becomes "High", and the reset condition is released.

IC2001 and IC2002 each have their own oscillator. The 55.5MHz crystal X2201, is utilised for IC2201, whilst IC2202 uses a variable capacitance diodę D2219 to achieve the desired oscillating frequency of 22MHz.

IC2201 has two main functions. The first is to acquire the teletext information.

The video signal is applied to Q211 and Q210, then input to pin 6 of IC2201. Teletext CLOCK and DATA outputs are then obtained from pins 17 and 18 of the IC.

Secondly, a composite sync. signal is required. The video input at pin 6 of 1C2001 is also applied to pin 2 via C2205 and R2208. A composite sync. signal is then madę available from pin 14 of IC2201.

The DATA, CLOCK, and SYNC. signals are then applied to pins 10, 11, and 12 of IC2202 for further processing.
