SAFETY PRECAUTION
X-RADIATION PRECAUTION
The primary source of X-RADIATION in the television receiver is the picture tube. The picture tube is specially
constructed to limit X-RADIATION emissions. For continued X-RADIATION protection, the replacement tube
must be the same type as the original including suffix letter. Excessive high voltage may produce potentially
hazardous X-RADIATION. To avoid such hazards, the high voltage must be maintained within specified limit.
Refer to this service manual, high voltage adjustment for specific high voltage limit. If high voltage exceeds
specified limits, take necessary corrective action. Carefully follow the instructions for +B1 volt power supply
adjustment, and high voltage adjustment to maintain the high voltage within the specified limits.
PRODUCT SAFETY NOTICE
SPECIFICATIONS
Product safety should be considered when a component replacement is made in any area of a receiver.
Components indicated by markin the parts list and the schematic diagram designate components in which
safety can be of special significance. It is particularly recommended that only parts designated on the parts list in
this manual be used for component replacement designated by mark. No deviations from resistance wattage
or voltage ratings may be made for replacement items designated by mark.
1: An isolation transformer should be connected in the
power line between the receiver and the AC line
when a service is performed on the primary of the
converter transformer of the set.
2: Comply with all caution and safety-related notes
provided on the cabinet back, inside the cabinet, on
the chassis or the picture tube.
3: When replacing a chassis in the cabinet, always be
certain that all the protective devices are installed
properly, such as, control knobs, adjustment covers
or shields, barriers, isolation resistor-capacitor networks
etc. Before returning any television to the customer,
the service technician must be sure that it is completely
safe to operate without danger of electrical shock.

Scart2
This is an LA42052 which is the audio amplifier for the set. It has left and right inputs from the LOC and left and right
outputs to the speakers and headphone socket. It also has mute and standby functions which are activated by the
LOC as appropriate.
IC1101 (monitor sets only)
This is a switching IC, NJM2233BM, which allows the sync signal input on monitor sets to be switched between pin
20 of SCART 1 (conventional & ALBOS) and pin 14 of SCART 1 (SIS signal). The IC takes a 5V supply and is
switched by the control line SC2_8, which is normally used for SCART 2 pin 8 signalling but is adapted fro the moni-
tor sets.
IC1205
This a ROHM BA7603F triple video switch which allows the RGB input to be switched between SCART 1 and
SCART 2. The switch is controlled by the RGB_SW line from the IC.
IC2001
This is a picture improvement chip, Philips TDA9178, which takes a YUV input from the LOC and carries out vector
processing of luminance and colour to improve overall picture quality and reduce noise. The IC requires an 8V
power supply and is also connected to the I2C bus.
IC201
This is the Philips LOC 1 chip which is the main system processor. It consists of three ICs encapsulated in one BGA
package with 388 balls. The “Cosmic” and “Picasso” chips carry out analogue and digital processing respectively,
and together from the UOC III which is used in many other sets. These are complemented by the Lithium IC which
carries out digital processing and scaling functions.
The IC requires 5V, 3.3V and 1.8V for correct operation – although only 5V and 3.3V are required in “standby”
mode. Full descriptions of all port functions are given elsewhere in this manual.
IC1221(digital only)
This is a ROHM BA7609F triple video switch which allows audio and video from the digital system to be output to
the SCART 2 socket for recording. The IC is controlled by the REC_CTL signal from the MCU IC860.
IC4001
This is a SST SST39VF020 CMOS multi-purpose flash with a capacity of 2Mbits. It is connected to the LOC using
address lines, data input/output, write enable and control lines. The flash IC is powered by the 3V3 SW supply.
IC4002
This is a ROHM BD5260G open drain voltage detector IC which works in conjunction with the backlight enable line
BL_EN. It takes input from the main power and the 5V CPU line.
IC6600
This is a chopper regulator, Sharp PQ1CY series, which provides the power for the LCD panel – 3.3V for 15” and
20”, 5V for 17” and 23”. The regulator is switched on at power up via the control line POWER 1 and transistor
Q6600. The power is switched to the panel, also by POWER 1, via the FET switch Q1600.
IC6602
This is a Sharp PQ1CZ series chopper regulator which provides the 14V supply for the audio IC. It is switched by
the control line POWER 1 from the LOC.

IC Descriptions for UK1A (continued)
IC6603(digital only)
This is a Sharp PQ1CZ series chopper regulator which provides the 6V supply for the digital module, hence it is only
present on digital sets. The regulator is switched by the POWER 1 control line from the LOC.
IC6604
This is a linear voltage regulator providing in this case 8V to supply the picture improvement IC IC2001. The regulator is switched by the control line POWER 1.
IC6605
This is a chopper regulator, Sharp PQ1CY series, which provides 6V. This voltage is clamped by a diode after the
regulator to produce 5V CPU. This voltage is passed to IC 6606.
IC6606
This is a linear voltage regulator, ROHM BA05SFP, which takes the 6V from IC6605 as an input and produces 5V
SW. This regulator is controlled by the POWER 1 control line from the LOC.
IC6607
This is a linear voltage regulator which takes the 6V from IC6605 and produces 3V3 STB used by the LOC in standby mode.
IC6608
This is a ROHM BA00BC0WFP linear regulator which converts the 6V from IC6605 to the 1V8 use by the LOC
when the set is powered on. This regulator is controlled by the POWER 1 control line.
IC6642
This is also a ROHM linear regulator which takes the 5V SW from IC6606 as an input and produces 3V3 SW used
by various parts of the circuit.
IC701 (20” LCD only)
This is a THine THC63LVDF84B LCD panel interface which converts 4 LVDS data streams from the LOC into 28bits
of RGB data and a clock to send to the panel. Currently this IC is only required on 20” LCD sets where the panel
requires data in RGB form rather than LVDS.
The IC requires a 3V3 power supply on several pins.
IC801
This is the non-volatile memory(NVM) IC which contains data settings for the LOC and stored user data such as picture settings and programs. It also contains data relating to the LCD panel type and data requirements. It is a 24C64
64K EEPROM arranged as 8192 x 8bits. It uses the 3V3 STB power supply and is connected to the LOC via the
12C bus.
IC860(digital only)
This is a Renesas RSF21162SP microprocessor which acts as a controller for the digital module via the I2C bus and
the D/A_CTL and REC_CTL line to IC1251 and IC1221. This IC has a small amount of memory which contains the
ICs program, this is programmed separately from the LOC program via the KSUB socket.
IC861(digital only)
This is a ROHM BD4828G CMOS voltage detector which controls the reset line to the IC860 microprocessor.

PARTS DESCRIPTION AND READING IN SCHEMATIC DIAGRAM
1. The parts specification of resistors, capacitors and
coils are expressed in designated code. Please
check the parts description by the following code
table.
2. Some of transistors and diodes are indicated in
mark for the substitution of parts name. Please
check the parts name by the following code table.
3. Voltages and waveforms were taken with a video
colour bar signal(1Vp-p at 75 ohms terminated) and
controls to normal.
4. Voltages were taken with a high-impedance digital
voltmetre.

CHASSIS ELECTRICAL PARTS LIST
Product safety should be considered when a component replacement is made in any area of a receiver.
Components indicated by a mark in this parts list and the circuit diagram show components whose value have
special significance to product safety. It is particularly recommended that only parts specified on the following
parts list be used for components replacement pointed out by the mark .
