SAFETY PRECAUTIONS

WARNING: The following precautions should be observed. 1. Do not install, remove, or handle the picture tube 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 tube away from the body while handing.
When service is required, an isolation transformer should be inserted between power line 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 note 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 ▲ 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.
8. 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 sure that no protective device built into the instrument by the manufacturer has become defective, or inadvertently damaged during servicing. Therefore, the following checks are recommended for the continued protection of the customers and service technicians.

INSULATION

Insulation resistance should not be less than 7MΩ at 500V Insulation resistance should not be less than 7MΩ 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 tube 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 33.4kV on the chassis.

X-RADIATION

TUBES: The primary source of X-radiation in this receiver is the picture tube. The tube utilised for the above mentioned function in this chassis is specially constructed to limit Xradiation. For continued X-radiation protection, replace tube 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 Manual. 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 Manual, 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 Manual. A subscription to, or additional copies of HITACHI Service Manuals, may be obtained at a nominal charge from your HITACHI SALES OFFICES.

TUBE DISCHARGE

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

有关安全上的预防事项

警告:要检修必须遵守下列预防事项

要装入,取出或处理显象管时必须带上防碎玻璃用的护目镜。处理显象管时不带这护目镜的人不可接近。显象管应放在离开人体的地方。
需要维修时,在维修底盘之前,应将绝缘变压器插入电源线与接收机之间。
将底盘装入机箱里面时,所有的保护装置如隔板、非金属的调整钮、小室盖子或小室屏蔽、隔离用电阻,电容器等也应该装回去。
4. 开始检修之前应该注意原来的引线包层。尤其是在高压电路部分需要特别小心,必须认请正确的引线包层。尤其要注意R.G.B.引线包层部分。请确认这些部分的包层是否良好,以便使这些部分与水平扫描和F.B.T.电路隔离。
5. 更换零件时,请使用制造厂家所供应的零件。请更换原庄垫片并维持引线长度。尤其对于更换零件一览表上标有∆的重要零件,更换时绝不可使用其它厂家的产品。另外,当电路发生短路时,凡是有过热痕迹的零件,都要进行更换。
6. 将修好的电视机送回顾客以前,检修人员应该彻底试验机器以保证它完全安全,绝没有电击的危险,并确实检查机器内部的各种保护装置, 以保证这些部分没有因检修而失灵。由于上面理由,检修人员最好实行以下各项检查,以保证顾客和检修人员的安全。

绝缘

电源电极与任何可触及的金属部分之间的绝缘电阻不可小于7兆欧姆(加上直流500伏电压时)。同时, 在电源电极与任何可触及的金属部分之间加上3千伏的交流电压或4.25千伏的直流电压(2分钟)而试验其绝缘强度时,不可发生闪铬或绝缘击穿等显象。

高压

高压必须被维持在底盘的额定值,不能高于该值。如操作电压过高,会导致显象管或高压电源发生故障。同时,电压超过设计值时,在某种环境下,会产生X射线。因此,在任何环境下,高压不能超过底盘上的33.4千伏。

X射线

显象管:这部电视机所产生的X射线,其主要的来源是显象管。所以这部电视机所使用的显象管有特别的构造设计,使X射线尽量少。为了能继续防止X射线起见,要交换显象管时请一定使用相同型号的日立显象管。

有关制品安全上的注意事项

日立电视机所使用的许多机件具有有关安全的特别性能。这种特别性能在表面上往往看不出来,而且即使使用额定电压或功率更大的其他替换用机件也不一定可得到这些日立机件所保证的保护性能。在这本检修手册里面有指定这些具有特别安全特性的替换用机件。在这本检修手册的简图和替换用机件表上附带Δ记号的机件就表示具备这种特别的安全特性。

如果不使用这本检修手册机件表上HITACHI所推荐的替换用机件而使用没有同样安全特性的其他替换用机件的话,就可能会发生电击、失火、X射线等事故。HITACHI对制品安全不断努力改进,经常发出新的技术指令。如需要新的技术情报就请参看最新的 HITACHI检修手册。可向HITACHI销售公司预订或增订"日立检修手册",只收取极少费用。

电路说明 CIRCUIT DESCRIPTION

Tuner and I. F. Stages:

The tuner used on this chassis, is powered by the +9V, supply, and covers VHF, UHF and CATV Hyper Band. The I. F. output from the tuner is applied to amplifier Q201 then input to CP201.

Sound I.F. Stages :

The sound i.i. stages : the sound stages consist of IC201, which is basically a demodulator, and IC4501, which is the output amplifier. The I.F. signal at the collector of Q201, is fed via filter CP201 and input to IC201 at pins 45 and 45

CP201, and input to local at pine to and to. The composite signal output from pin 7 of IC201 is input to sound filters, MF402, MF403 and MF404, and selected with the mode shown in Table 1 at IC451 after being output from the filter. The selected signal is then input to pin 5 of IC201 via C422.

Demodulation is then performed by the IC, with the sound output being obtained from pin 50. It is then input to pins 2,5 of IC4501 via C408, for further amplification, and output to the speaker from pins 7, 12.

5 of IC201. This is obtained via R427 from pin 8 of IC1101. Sound demodulation output at pin 1 of IC201, is applied to the terminal of rear via Q401. From the output terminal, the audio signal can be output to external equipment if desired. Audio signals from external equipment can be applied to the input terminal of rear. They are then input to IC201 at pin 6.

When connecting audio signals this way, a "High" is applied to pins 16 of 16201 from 161101, thereby changing the internal switching circuitry of the 1C.

	L	L		MF404 (6.5MHz)	111 302

/ision L.F. Stages

The I.F. signal from CP201 is input to pins 45 and 46 of IC201. 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 to pin 48.

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 L202 etc., connected between pins 2 and 3 of the IC. This produces a reference frequency which is utilised for synchronous video detection.

An RF AGC voltage is made available at pin 48 of IC201, the starting level of which is determined by the voltage applied to pin 49, which in turn is fixed by the setting of VR202. This AGC voltage is then fed to the tuner via R208 to control its gain accordingly.

The composite video finally emerges at pin 7 of 1C201.

Luminance Circuitry :

The composite video signal output from pin 7 of IC201 is applied to the sound rejection filter MF501, and MF502.

CMT2199

The resulting luminance signal is applied to the terminal of rear, for output to external equipment if desired.

It is then returned to pin 13 of IC201 via Q506, for colour decoding and deflection synchronisation. The luminance signal is added internally to the R.G.B. matrix

circuits of IC201, as well as being controlled by the brightness, contrast, and blanking stages of the IC.

The luminance signal finally emerges with the R.G.B. signals from pins 18, 19 and 20 of IC201. The voltages to control the contrast and brightness levels are

output from pins 3 and 4 of IC1101, then applied to pins 17 and 25 of IC201.

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 fall. This fall is applied to the cathode of D758, then via R760 to pin 25 of IC201, thereby reducing the contrast level and hence the beam current. Video inputs from external equipment connected to the terminal of rear, are fed to IC201 pin 15.

When the external mode is selected, a "High" is applied to pin 16 of IC201.

Chrominance Circuitry ;

1620L is designed to demodulate PAL, NTSC and SECAM systems. And this IC can distinguish between PAL, NTSC or SECAM signals. The demodulated colour signals are output from IC201 pins 30 and 31 as the R-y and B-y signals, then fed to pins 14 and 16 of IC501 which is a switch capacitor delay line. IC201 allows bi-directional communication between the SECAM decoder IC502 and automatic system manager for SECAM identification. It delivers the VCX0 (voltage controlled xtal osillator) reference freguency (4, 43MHz only) to the SECAM decoder via pin 32 of IC201. Once SECAM is identified, the gated reference signal is outputted to pin 32 of IC201. The 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 640 Seconds.

This internal clock is generated from a BMz voltage controlled oscillator, and line locked by the sandcastle pulse input at pin 5. Low pass filters after the delay line stages suppress the clock signals.

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

These outputs are then fed to IC201 at pins 28 and 29. This IC contains clamping circuits, and a DC colour saturation control, the level of which is set by the voltage applied to pin 26 from pin 5 of IC1101. The signals are then applied to a MATRIX circuit, and finally emerge from pins 18, 19 and 20 as the blue, green, and red signals.

Deflection Circuits :

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

Page 4

Harizontal State .

The composite video signal from pin 7 of IC201 is returned to pin 13 via C302 as explained previously. This input is applied to the internal sync. separator stages of the IC. A internal phase detector stage is provided with a sawtooth waveform, generated from the line pulse input to pin 38. The phase detector will then compare this sawtooth waveform to the sync. pulse. Any frequency drift will cause a corrective output to be applied to the horizontal oscillator, thereby maintaining the desired phase relationship.

The components connected to pin 40 form a filter network for the phase detector, and NR701/connected to pin 39 provides manual phase control. The horizontal output emerges at pin 37 and is then applied to the base of line drive transistor 0721, T721 couples the output of 0721 to the line output transistor 0781. Both these transistors are powered by the 95V supply. A line pulse available at pin 6 of the flyback transformer is rectified by D751, smoothed by C756 and provides approximately 170V to drive the output transistors Q851, Q852, Q853. Under certain fault conditions, i.e. increased H.T. supply, low line oscillator frequency, or reduced value of the tuning capacitor C781, an excess of E.H.T. could be developed. To prevent this happening, the rectified voltage of D751 is fed via potential divider R757, R758, and applied to 2D751. Should the E.H.T. rise excessively, the threshold of the zener will be exceeded, and a voltage will be applied to pin 35 of 10:101

This effectively applies a "Low" to Q954 base, turning the transistor off. Consequently, Q953 will be turned off, and the +8V supply to IC201 is then removed, thereby shutting down the deflection stages of the IC, 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 H.T. current to the horizontal output stages is measured by R781.

Should the current rise, the voltage drop across R781 will increase, and a voltage will be applied to the gate of Q955. This will then prevent further E.H.T. generation as described earlier

A supply of +25V is required for ICG81. This is obtained from pin 1 of the flyback transformer, and smoothed by C754.

Vertical Stages:

The internal vertical sync. of IC201 is fed to a triggered vertical divider stage, which 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. C601 at pin 42 of the IC is used for ramp generation, and

produces the required sawtooth output.

The Vertical output from bin 45 of field is applied to bin 4 of 10581 via R604. The components D601 and C605 determine the flyback generation time, and the vertical output to drive the deflection coils is made available from pin 2. The deflection current that occurs at the junction of R609, is added to the feedback from R607/C608 etc. and the result is applied to pin 41 of 10201. The values of R607 and C608 determine the linearity, whilst VR601 sets the vertical height.

Power Supply Circuit:

(1) Starting operation

Stating operation • Power switch S901 turned ON → Rectified at D901~D904 → Voltage at Q903 base rises → First Switching pluse generated at winding (P1-P2) of T901 → Drive voltage → Provide to Q905 of winding (B1-B2) of T901 → Q905 supply stable drive current to Q903 base → come into normal operation.

Switching constant voltage operation AC input voltage rises or +B load decreased (picture)

AC input voltage rises or +B load decreased (picture gets dark) → +B (95V) rises → Ic increased at Q951 → Id increased at IC901 → Ic increased at IC901 → Voltage decreased at pin (5) of IC901 → ON period of Q901 increased → ON period of Q903 decreased → Positive voltage of D951 anode decreased → +B voltage falls → +B voltage stabilized. Standby operation

Remote control power OFF → IC1101 (2) and (2) T → Q954 OFF → Q953 OFF → IC201 H. Start Pin (2) stopped → Horizontal deflection stopped. Also → Q952 OFF → R965 connect into R964 → Voltage of Q951 base rises → ON period of Q903 is slightly decreased by IC901 → +B voltage falls (about 62V) → Power consumption decreased. +5V power provided from T901 (S3-S4) winding through D952 and C954 → 5V at pin (2) of IC1101 stabilized by ZD1101.

Remote Control and Tuning Circuitry :

The remote control receiving unit CP1201, contains an infrared amplifier and powered by the +5V supply, which is stabilized by ZD1101. The output from pin 2 of this unit is applied to pin 16 of IC1101.

This IC type M37210MA, performs channel selection. UP/DOWN analogue control, an screen display, search tuning, and controls inputs and search tuning, and controls inputs and outputs to and from the AV terminal. IC102 is the memory IC, which stores the data relating to the

ICLIDZ is the memory IC, which stores the data relating to the above functions, then transfers that information to IClIO1 when required. Both these ICs are powered by the +5V supply. X1101 supplies IClI01 with a basic clock frequency which controls all operating mode requirements.

When the TV is first switched on, IC1101 must be initially reset, and this is achieved by IC1101 stage. As the +5V supply begins to rise from switch on, pin 3 of Q1105 is held "Low". This is applied to pin 30 of IC1101 thus resetting the IC. Once pin 1 of Q1105 has almost reached its +5V potential. the "Low" is removed from pin 3 thus releasing the reset condition.

When the search routine has been initiated and a signal has been located, pin 14 of IC201 will become "High". This is applied to pin 34 of IC1101, and informs the IC that a signal is present. The search routine then stops, and the IC will monitor the AFC signal present at pin 15 to obtain the optimum signal.

Pins 46 and 47 control the signal system.

Contrast, colour, brightness, sharpness, tint, and volume are all controlled from the remote control handset (the volume can also be adjusted by + and - buttons on the front of the TV),

and will produce DC level changes from pins 3~8 of IC1101, which are then fed to the relevant pins of IC201.

Pins 31-32, 37-39, and 11 from the in and out matrix are for the front control operations. Pins 12 and 13 are the clock and data output pins. These

signals are supplied to the memory IC1102.

It is supplied to pin 16 of IC201. When "High", the IC will process external inputs applied to pins 13 and 15, and when "Low", the internal signals are processed.

CMT2199

"Low, the internal signals are processed. The handset button marked TV/VIDEO will need to be pressed. This will then produce the required "High" from pin 20 to achieve the necessary switching, as explained earlier.

The red, green and blue on-screen display signals are output from pins 50, 51 and 52. The components L1102, C1102, and C1103, on pins 28 and 29, determine the display oscillator frequency. The horizontal and vertical inputs at pins 1 and 2 determine the actual position of the on screen display. When a command requiring an on-screen display is received by IC1101. a "Hieh" will be output from pin 49.

This is applied to pin 21 of 16201, and blanks out a portion of the picture. The on-screen display information is then inserted into this portion, thus resulting in a clear display. When the ALARM mode has been set, and the time input has elapsed an output is obtained form ain 64 of 161101

elabsed, an output is obtained from pin 40 of 101101. This is then applied via R1184, R1119, C1111, R1118 etc. to pins 2 and 5 of (C4501 thus causing a "Bleep" sound to be heard.

Once the "OFF" timer mode has been set, and the time input has elapsed, pins 21 and 22 of iC1101 output a "Low".

This removes the supply to the base of Q003, and as a result the +9V output of Q902 disappears. This places the TV into its standby mode of operation by removing E. H. T. generation as explained previously. When the "ON" time has been estimated and set the standby

when the UN time has been estimated and set, the standby command must be transmitted by the handset, to place the TV into its standby mode. As an indication that the standby mode is only temporary, pin 20 of IC1101 is taken "High" and "Low" alternately, causing D1114 to flash on and off.

When the entered time has elapsed, the "Low" outputs from pins 21 and 22 of IC1101 are removed, and the TV will return to normal operation.
