IMPORTANT SERVICE SAFETY INFORMATION

Operating the receiver outside of its cabinet or with its back removed involves a shock hazard.

Work on these models should only be performed by those who are thoroughly familiar with

2

SERVICE MANUAL TK-A/Q

precautions necessary when working on high voltage equipment.

Exercise care when servicing this chassis with power applied. Many B plus and high voltage

RF terminals are exposed which, if carelessly contacted, can cause serious shock or result in damage

to the chassis. Maintain interconnecting ground lead connections between chassis, escutcheon,

picture tube dag and tuner when operating chassis.

These receivers have a “polarized” AC line cord. The AC plug is designed to fit into standard

AC outlets in one direction only. The wide blade connects to the “ground side” and the narrow blade

connects to the hot “side” of the AC line. This assures that the TV receiver is properly grounded to

the house wiring. If an extension cord must be used, make sure it is of the “polarized” type.

Since the chassis of this receive is connected to one side of the AC supply during operation,

service should not be attempted by anyone not familiar with the precautions necessary when

working on these types of equipment.

When it is necessary to make measurements or tests with AC power applied to the receiver

chassis, an Isolation Transformer must be used as a safety precaution and to prevent possible

damage to transistors. The Isolation Transformer should be connected between the TV line cord

plug and the AC power outlet.

Certain High voltage (HV) maybe cause X-ray radiation. Receivers should not be operated with

HV levels exceeding the specified rating for their chassis type. Higher voltage may also increase the

possibility of failure in the HV supply.

It is important to maintain specified values of all components in the horizontal and high voltage

circuits and anywhere else in the receive that could cause a rise in high voltage, or operating supply

voltages. No changes should be made the original design of the receiver.

Components shown in the shaded areas on the schematic diagram and/or identified by in the

replacement parts list should be replaced only with exact factory recommended replacement parts.

The use of unauthorized substitute parts man creates may create shock, fire, X-ray radiation, or other

hazards.

To determine the presence of high voltage, use an accurate high impedance HV meter

connected between the second anode lead and he CRT dag grounding device. When servicing the

High Voltage System remove static charges from it by connecting a 10K Ohm resistor in series Wan

insulated wire(such as test probe) between the picture tube dag and 2nd anode lead(Have AC line

cord disconnected from AC supply).

SERVICE MANUAL TK-A/Q

The picture tube use in this receiver employ integral implosion protection. Replace with a tube

of the same type number for continued safety. Do not lift picture tube by the neck. Handle the

picture tube only when wearing shatterproof goggles and after discharging the high voltage

completely, Keep others without shatter proof goggles away.

Before returning the receiver to the user, perform the following safety checks:

1. Inspect all lead dress to make certain that leads are not pinched or that hardware is not

lodged between the chassis and other metal parts in the receiver.

2. Replace all protective devices such as non-metallic control knobs, insulating fish-papers,

cabinet backs, adjustment and compartment covers of shields, isolation resistor-capacitor networks,

mechanical insulators etc.

3. To be sure that not shock hazard exists, a check for the presence of leakage current should be

made at each exposed metal part having a return path to the chassis (antenna, cabinet metal, screw

heads knobs and/or shafts, escutcheon, etc.) in the following manner.

Plug the AC line cord directly into a 110V/220V/240V AC receptacle. (Do not use an Isolation

Transformer during these checks.) All checks must be repeated with the AC line cord plug

connection reversed. (If necessary, a non-polarized adapter plug must be used only for the purpose

of completing these checks.)

If available, measure the current using an accurate leakage current tester. Any reading of

0.35mA or more is excessive and indicates a potential shock hazard which must be corrected before

returning the receiver to owner.

If a reliable leakage current tester is not available, this alternate method of measurement should

be used. Using two clip leads, connect a 1500 Ohm, 10 watt resistor paralleled by a 0.15MF

capacitor in series with a known earth ground, such as a water pipe or conduit and the metal part to

be checked. Use a VTVM or VOM with 1000 Ohms per Volt, or higher, sensitivity to measure this

AC voltage drop across the resistor,. Any reading of 0.35 volt RMS of more is excessive and

indicates potential shock hazard which must be corrected before returning he receiver to the owner.

IC INFORMATION

1. PHILIPS UOCIII CHIP – TDA110XXH1/TDA120XXH1 (N603)

12

SERVICE MANUAL TK-A/Q

1.1 General description

The UOCIII series combines the functions of a Video Signal Processor (VSP) together with a

FLASH embedded TEXT/Control/Graphics µ-Controller (TCG µ-Controller) and US Closed

Caption decoder. In addition the following functions can be added:

Adaptive digital (4H/2H) PAL/NTSC comb filter

•

• Teletext decoder with 10 or 100 page text memory

Multi-standard stereo decoder

•

• BTSC stereo decoder

Digital sound processing circuit

•

• Digital video processing circuit

The UOCIII series consists of the following 3 basic concepts:

• Stereo versions. These versions contain the TV processor with a stereo audio selector, the TCG

µ-Controller, the multi-standard stereo or BTSC decoder, the digital sound processing circuit and

the digital video processing circuit. Options are the adaptive digital PAL/NTSC comb filter and a

teletext decoder with 10 or 100 page text memory.

• AV stereo versions. These versions contain the TV processor with stereo audio selector and the

TCG µ-Controller. Options are the digital sound processing circuit, the digital video processing

circuit, the adaptive digital PAL/NTSC comb filter and a teletext decoder with a 10 page text

memory.

• Mono sound versions. These versions contain the TV processor with a selector for mono audio

signals and the TCG µ-Controller. Options are the adaptive digital PAL/NTSC combfilter and a

teletext decoder with 10 page text memory.

The ICs are mounted in a QFP-128 package and can be used in economy television receivers

with 90 and 110 picture tubes. The package is according to the ROHS legislation, which also

means that the package is lead-free. The ICs have supply voltages of 5V, 3.3V. Also an 1.8V supply

is needed, but this can be simply derived by adding an emitter follower at a reference voltage from

the device.

1.2 Features

1.2.1 Analogue Video Processing (all versions)

13

SERVICE MANUAL TK-A/Q

* Multi-standard vision IF circuit with alignment-free PLL demodulator

* Internal (switchable) time-constant for the IF-AGC circuit

* Switchable group delay correction and sound trap (with switchable centre frequency) for the

demodulated CVBS signal

* DVB/VSB IF circuit for preprocessing of digital TV signals.

* Video switch with 3 external CVBS inputs and a CVBS output. All CVBS inputs can be used as

Y-input for Y/C signals. However, only 2 Y/C sources can be selected because the circuit has 2

chroma inputs. It is possible to add an additional CVBS(Y)/C input (CVBS/YX and CX) when the

YUV interface and the RGB/YPBPR input are not needed. It is also possible to insert a CVBS/Y

signal at the SVO/IFVOUT output.

* Automatic Y/C signal detector

* Integrated luminance delay line with adjustable delay time

* Picture improvement features with peaking (with switchable centre frequency, depeaking, variable

positive/negative peak ratio, variable pre-/overshoot ratio and video dependent coring), dynamic

skin tone control, gamma control and blue- and black stretching. All features are available for CVBS,

Y/C and RGB/YPBPR signals.

* The effect of the various features can de demonstrated by means of a ‘split screen’ mode in which

the features are activated in one half of the picture and switched off in the other half

* Switchable DC transfer ratio for the luminance signal

* Only one reference (24.576 MHz) crystal required for the TCG µ-Controller, and the colour

decoder

* Multi-standard colour decoder with automatic search system and various “forced mode”

possibilities

* Internal base-band delay line

* Indication of the Signal-to-Noise ratio of the incoming CVBS signal

* Linear RGB/YPBPR input with fast insertion.

* YUV interface. When this feature is not required some pins can be used as additional

RGB/YPBPR input. It is also possible to use these pins for additional CVBS (or Y/C) input

(CVBS/YX and CX).

* Tint control for external RGB/YPBPR signals

* Scan Velocity Modulation output. The SVM circuit is active for all the incoming CVBS, Y/C and

14

SERVICE MANUAL TK-A/Q

RGB/YPBPR signals.

1.2.2.2 Stereo versions

* The low-pass filtered ‘mixed down’ I signal is available via a single ended or balanced output

stage.

1.2.3 Sound Demodulation (all versions)

* Separate SIF (Sound IF) input for single reference QSS (Quasi Split Sound) demodulation.

* AM demodulator without extra reference circuit

* The mono intercarrier sound circuit has a selective FM-PLL demodulator which can be switched

to the different FM sound frequencies (4.5/5.5/6.0/6.5 MHz). The quality of this system is such that

the external band-pass filters can be omitted.

* The FM-PLL demodulator can be set to centre frequencies of 4.72/5.74 MHz so that a second

sound channel can be demodulated. In such an application it is necessary that an external bandpass

filter is inserted.

* The vision IF and mono intercarrier sound circuit can be used for the demodulation of FM radio

signals. With an external FM tuner also signals with an IF frequency of 10.7 MHz can be

15

demodulated.
