SAFETY PRECAUTIONS

WARNING: The following precautions must be observed.

ALL PRODUCTS

1. Before any service is performed on the chassis an isolation transformer should be inserted
between the power line and the product.

2. When replacing the chassis in the cabinet, ensure all the protective devices are put back in
place.

3. When service is required, observe the original lead dressing. Extra precaution should be taken
to ensure correct lead dressing in any high voltage circuitry area.

4. Many electrical and mechanical parts in HITACHI products 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  on the schematics and the replacement
parts list.
The use of a substitute replacement component that does not have the same safety
characteristics as the HITACHI recommended replacement one, shown in the parts list, may
create electrical shock, fire, X-radiation, or other hazards.

5. Always replace original spacers and maintain lead lengths. Furthermore, where a short circuit

has occurred, replace those components that indicate evidence of overheating.

6. Insulation resistance should not be less than 2MΩ at 500V DC between the main poles and
any accessible metal parts.

7. 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.

8. Before returning a serviced product 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.
The service technician must make sure that no protective device built into the instrument by the
manufacturer has become defective, or inadvertently damaged during servicing.

CE MARK

1. HITACHI products may contain the CE mark on the rating plate indicating that the product
contains parts that have been specifically approved to provide electromagnetic compatibility to
designated levels.

2. When replacing any part in this product, please use only the correct part itemised in the parts
list to ensure this standard is maintained, and take care to replace lead dressing to its original
state, as this can have a bearing on the electromagnetic radiation/immunity.

LASERS

If the product contains a laser avoid direct exposure to the beam when the cover is open or when
interlocks are defeated or have failed.

LEAD FREE SOLDER



This product uses lead free (unleaded) solder to help preserve the environment. Please read these instructions
before attempting any soldering work.

Caution:

Always wear safety glasses to prevent fumes or molten solder from getting into the eyes. Lead free solder can
splatter at high temperatures (600°C).

Lead Free Solder Indicator

Printed circuit board assemblies using lead free solder shown below are engraved with an "F" following Board
Name.

Properties of Lead Free Solder

The melting point of lead free solder is 40~50°C higher than leaded solder.

When Servicing Solder

Solder with an alloy composition of Sn-3.0Ag-0.5Cu or Sn-0.7Cu is recommended.
Although servicing with leaded solder is possible there are a few precautions that have to be taken. (Not taking

these precautions may cause the solder not to harden properly and lead to consequent malfunctions.)

Precautions when Using Leaded Solder

• Remove all lead free solder from soldered joints when replacing components.

• If leaded solder should be added to existing lead free joints, mix in the leaded solder thoroughly after the

lead free solder has been completely melted (do not apply the soldering iron without adding solder).

When Servicing Soldering Iron

A soldering iron with a temperature setting capability (temperature control function) is recommended.
The melting point of lead free solder is higher than leaded solder. To avoid poor servicing performance, use a

soldering iron that maintains a high stable temperature (large heat capacity) and that allows temperature
adjustment according to the part being serviced.

Recommended Soldering Iron

Soldering iron with temperature control function (temperature range: 320~450°C)
Recommended temperature range for each part type:

Part to be Soldered

PCB with surface mount devices 320 ±30°C
PCB without surface mount devices 380 ±30°C
Chassis, metallic shield, etc. 420 ±30°C

Tuner/Video Chroma (Schematic Sheet 1)

VHF/UHF asymmetric type tuner converts RF input signal to IF signal output through pin 11. AGC voltage
is supplied at pin 1 from IC100 pin 62. IF output goes through buffer Q101 to SAW filter SAW100 for VIF at
pin 2 and 3 of IC100 and to SAW101 for SIF at pin 63 and 64.

4.2.1. IF Demodulator and Video Chroma

Demodulated video signal is output from pin 10 going to sound traps. There are two sound traps,
TR100 for I/L signal and TR101 for BG, outputs from which are switched by SOUND-SWITCH from
IC301 pin 5.

After group delay correction at pin 13, it is connected to pin 14 where TV picture is supplied into video
switch. The TV signal from pin13 is also connected to SCART1 as TV signal output.

Quasi Split Sound converted from SIF input is output at pin 5 to connect with sound decoder IC301.
H and V sync pulses are output at pin 60 and 61 to go to FC/MSC for Synchronisation to convert
progressive scan. H pulse must be inverted by Q126.

When selecting one of video signal in video switch of IC100, CVBS signal is going to COMB filter if the
video is CVBS PAL/NTSC format. Then Y/C separated signal is coming back at pin 28 and 29. The
clock must be provided from pin 30. The video or Y/C signal selected pass through video chroma
section and finally converted to YUV format at pin 49, 50, 51. IC100 is supplied 4.43MHz and 3.58MHz
clock from crystal X100 and X101, which is automatically selected according to the signal received. 2
RGB inputs are also switched at the last stage in IC100. RGB signals are also converted to YUV.

Interface Board (Schematic Sheet 3)

For Component Input, Progressive Sync Separation and Centre Audio Channel.
Sync separation for progressive YPbPr input (50Hz and 60Hz) are carried out at TA1370. Input video

signal is specifically given from AV4 and connected at pin 26 through clamping circuit constituted by
QC25~QC28. Sync separation for all input signal other than Progressive input are carried out at
TDA9321 (page 1). TA1370 includes switch of sync signal (H and V) between H/V input (pin I and
pin2) from TDA9321 and internal sync separation. TA1370 outputs H at pin16 and V at pin 28, which
are connected to PSF for FC4 board. There are 2 inputs of the connector for each main and sub. H
output at pin 16 on TA1370 is fed to IC10 to shorten H pulse waveform to avoid jittering.

2 inputs, main YUV from IC03 and RGB from micro (TELETXT), are switched and connected to sub­video input for FC4 (IC107). This is enabled when TV+TEXT is selected (SUB TELETEXT) and when
PC window is selected (SUB VIDEO)

4.6. Micro-controller (Schematic Sheet 5)

SCL3v3 and SDA3v3 are converted for 5V operation in Q700, Q701, Q705 & Q706. OSD/TEXT RGB
at pin 58/59/60 are synchronised with progressive sync pulses 2H (32KHz) at pin 32 and V (50/60Hz)
at pin 33. RGB and BLK are also converted to 5V operation at Q713, Q714, Q715 and IC707. AV link
is bi-directional bus from pin 10 of SCT101 made by Q709/D701~D703. For the micro, input and
output are separated. The signal level is also converted between 3V3 in micro and 5V for SCART.

See 'Micro-controller Pinout' in the PINOUT DATA section of this manual for microcontroller pin functions.

4.7. COMB Filter/SVHS Output (Schematic Sheet 6)

CVBS from IC100 pin 26 is filtered by C800, C801, L800, and C802 and connected to pin 3.
Y/C separate signals output from IC101 pin 25/23 are also filtered by Q801 base circuit and Q802
base circuit.

• Y is amplified to adjust the level at Q119/Q120 for return signal to IC100 and SVHS. Y signal
output via buffer Q803.

• C is amplified to adjust the level at Q121/Q122 for return signal to IC100 and SVHS. C signal
output via buffer Q804.

IC101 requires clock at pin 19 supplied from IC100.
