ANY PERSON ATTEMPTING TO SERVICE THIS CHASSIS MUST FAMILIARIZE HIMSELF WITH THE CHASSIS
AND BE AWARE OF THE NECESSARY SAFETY PRECAUTIONS TO BE USED WHEN SERVICING ELECTRONIC
EQUIPMENT CONTAINING HIGH VOLTAGES.
TELEVISION/MONITOR SAFETY GUIDELINES FOR THE PROFESSIONAL SERVICE TECHNICIAN
Safety Checks
After the original swevice problem has been corrected,a complete safety
check
should be made. Be sure to check over the entire set, not just the areas
where you have worked. Some previous servicer may have left an unsafe
condition,which could be unknowingly passed on to your customer. Be sure
to check all of the following:
Fire and Shock H azard
1. Be sure all components are positioned in such a way as to avoid the
possibility of adjacent component shorts. This is especially important
on those chassis which are transported to and feom the service shop.
2. Never release a repaired unit unless all protective devices such as
insulators, barries, covers, strain reliefs, and other hardware have been
installed in accordance with the original design.
3. Soldering and wiring must be inspected to locate possible cold solder
or damaged insulation ( including the ac cord).Be certain to remove
loose solder balls and all other loose foreign particles.
4. Check across-the-line components and other components for physical
evidence of damage or deteriortion and replace if necessary. Follow
original layout,lead length, and dress.
5. No lead or component should touch a receiving tube or a resistor rated
at 1 watt or more. Lead tension around protruding metal surfaces or
edges must be avoided.
6. Critical components having special safety characteristics are identified
with ans bythe Ref. No. in the parts list and enclosed within a broken line
* (where seceral criticalcomponents are grouped in one area) along with
the safety symbols on the schematic diagrams and/or exploded views.
7. When servicing any unit, always use a seoparate isolation transformer
for the chassis Failure to use a separate isolation transformer may
exopose you to possible shock hazard, and may cause damage to
servicing instruments.
8. Many electronic products use a polarized ac line cord (one wide pin on
the plug.) Defeating this safety feature may create a potential hazard to
the service and the user. Extension cords which do not incorporate the
polarizing feature should never be used.
9. After reassembly of the unit, always perform an leakage test or resistance
test from the line cord to all exposed metal parts of the cabinet. Also check
all metal control shafts(with knobs removed), antenna terminals, handles,
screws, etc. to be sure the unit may be safety operted without danger of
electrical shock.
* Broken line
Implosion
1. All picture tubes used in current model receivers are equipped with an
intergral implosion system. Care should always be used, and safety
glassesworn,whenever handling any picture tube. Avoid scratching or
other rwise damaging the picture tube during installation.
2. Use only replacement tubes specified by the manufacturer.
X-radiation
1. Be sure procedures and instructions to all your service personnel cover
the subject of X-radiation. Potential sources of X-rays in TV receivers are
the picture tube and the high voltage circuits. The basic precaution which
must be exercised is to keep the high voltage at the factory recommended
level.
2. To avoid possible exposure to X-radiation and electrical shock, only the
manufacturer's specified anode connectors must be used.
3. It is essential that the service technician has an accurate HV meter
available at all times. The calibration of this meter should be checked
periodically against a reference standard.
4. When the HV circuitry isoperating properly there is no possibility of an xradiation problem. High voltage should always be kept at the anufacture,s
rated value-no higher - for optimum performance. Every time a color set is
serviced, the brightness should be run up and down while monitoring the
HV with a meter to be certain that the HV is requlated correctlv and does
not exceed the specified value. We suggest that you and your technicians
review test procedures so that HV requation are always checked as a
standard servicing procedure, and the reason for this prudent routine is
cleary understood by everyone. It is important to use an accurate and
reliable HV meter. It is recommended that the HV recorded on each
customer's invoice, which will demonstrate a proper concern for the
customer's safety.
5. When troubleshooting and making test measurements in a receiver with
a problem of excessive high voltage, reduce the line voltage by means of
a Variac to bring the HV into acceptable limits while troubleshooting. Do
not operate the chassis longer than necessary to locate the cause of the
excessive HV.
6. New picture tubes are specifically designed to withstand higher operathng
voltages without creating undesirable X-radiation. It is strongly
recommended that any shop test fixture which is to be used with the new
higher voltage chassis be equipped with one of the new type tubes
designed for this service.Addition of a permanently connected HV meter
to the shop test fixture is advisable. The CRT types used in these new
sets should never be replaced with any other types,as this may result in
excessive X-radiation.
7. It is essential to use the specified picture tube to avoid a possible X-diation
problem.
8. Most TV receivers contain some type of emergency "Hold Down" circuit to
pervent HV from rising to excessive levels in the presence of a failure
mode. These various circuits should be understood by all technicians
servicing them, especially since many hold down circuits are inoperative
as long as the receiver performs normally.
Leakage Current Cold Check
1. Unplug the ac line cord and connect a jumper between the two prongs of
the plug.
2. Turn on the power switch.
3. Measure the resistance value between the jumpered ac plug and all
exposed cabinet parts of the receiver, such as screw heads, antennas,
and control shafts.When the exposed metallic part has a return path to
the chassis, the reading should be between 1 megohm and 5.2 megohms.
When the exposed metal does not have a return path to thr chassis, the
reading must be infinity.Remove the jumper from the ac line cord.

0.15 uF
INSTRUMENTS
EXPOSED
METAL PARTS
Leakage Current Hot Check
1. Do not use an isolation transformer for this test. Plug the completely
reassembled receiver directly into the ac outlet.
2. Connect a 1.5k, 10w resistor paralleled by a 0.15uf. capacitor between
each exposed metallic cabinet part and a good earth ground such as a
water pipe, as shown above.
3. Use an ac voltmeter with at least 5000 ohmsy volt sensitivity to measure
the potential across the resistor.
4. The potential at any point should not exceed 0.75 volts. Aleakage current
tester may be used to make this test; leakage current must not exceed
0.5 milliamps. If a measutement is outside of the specified limits, there is
a possibility of shock hazard. The receiver should be repaired and
rechecked before retutning it to the customer.
5. Repeat the above procedure with the ac plug reversed.( Note: An ac
adapter is necessary when a polarized plug is used. Do not defeat the
polarizing feature of the plug.)
Picture Tube Replacement
The primary source of X-radiation in this television receiver is the picture
tube.The picturetube utilized in this chassis 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,or a Philips
approved tupe.
Parts Replacement
Many electrical and mechanical parts in Philips television sets have special
safety related charcteristics. 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. The use of a substitute part which does not have the same safety
characteristics as the Philips recommended replacement part shown in this
service manual may create shock, fire, or other hazards

Regulatory Information
TCO'92 and TCO '99 Information
Why do we have environmentally labeled computers?
In many countries, environmental labeling has become an established
method for encouraging the adaptation of goods and services to the
environment. The main problem, as far as computers and other
electronics equipment are concerned, is that environmentally harmful
substances are used both in the products and during their manufacture.
Since it is not so far possible to satisfactorily recycle the majority of
electronics equipment, most of these potentially damaging substances
sooner or later enter nature.
There are also other characteristics of a computer, such as energy
consumption levels, that are important from the viewpoints of both the
work (internal) and natural (external) environments. Since all methods of
electricity generation have a negative effect on the environment (e.g.
acidic and climate-influencing emissions, radioactive waste), it is vital to
save energy. Electronics equipment in offices is often left running
continuously and thereby consumes a lot of energy.
What does labeling involve?
This product meets the requirements for the TCO'99 scheme which
provides for international and environmental labeling of personal
computers. The labeling scheme was developed as a joint effort by the
TCO (The Swedish Confederation of Professional Employees), Svenska
Naturskyddsforeningen (The Swedish Society for Nature Conservation)
and Statens Energimyndighet (The Swedish National Energy
Administration).
Approval requirements cover a wide range of issues: environment,
ergonomics, usability, emission of electric and magnetic fields, energy
consumption and electrical and fire safety.
The environmental demands impose restrictions on the presence and
use of heavy metals, brominated and chlorinated flame retardants,
CFCs (freons) and chlorinated solvents, among other things. The
product must be prepared for recycling and the manufacturer is obliged
to have an environmental policy which must be adhered to in each
country where the company implements its operational policy.
The energy requirements include a demand that the computer and/or
display, after a certain period of inactivity, shall reduce its power
consumption to a lower level in one or more stages. The length of time
to reactivate the computer shall be reasonable for the user.
Labeled products must meet strict environmental demands, for example,
in respect of the reduction of electric and magnetic fields, physical and
visual ergonomics and good usability.
Below you will find a brief summary of the environmental requirements
met by this product. The complete environmental criteria document may
be ordered from:
Environmental Requirements
Flame retardants
Flame retardants are present in printed circuit boards, cables, wires,
casings and housings. Their purpose is to prevent, or at least to delay
the spread of fire. Up to 30% of the plastic in a computer casing can
consist of flame retardant substances. Most flame retardants contain
bromine or chloride, and those flame retardants are chemically related
to another group of environmental toxins, PCBs. Both the flame
retardants containing bromine or chloride and the PCBs are suspected
of giving rise to severe health effects, including reproductive damage in
fish-eating birds and mammals, due to the bio-accumulative* processes.
Flame retardants have been found in human blood and researchers fear
that disturbances in fetus development may occur.
The relevant TCO'99 demand requires that plastic components
weighing more than 25 grams must not contain flame retardants with
organically bound bromine or chlorine. Flame retardants are allowed in
the printed circuit boards since no substitutes are available.
Cadmium**
Cadmium is present in rechargeable batteries and in the colorgenerating layers of certain computer displays. Cadmium damages the
nervous system and is toxic in high doses. The relevant TCO'99
requirement states that batteries, the color-generating layers of display
screens and the electrical or electronics components must not contain
any cadmium.
Mercury**
Mercury is sometimes found in batteries, relays and switches. It
damages the nervous system and is toxic in high doses. The relevant
TCO'99 requirement states that batteries may not contain any mercury.
It also demands that mercury is not present in any of the electrical or
electronics components associated with the labeled unit.
CFCs (freons)
The relevant TCO'99 requirement states that neither CFCs nor HCFCs
may be used during the manufacture and assembly of the product.
CFCs (freons) are sometimes used for washing printed circuit boards.
CFCs break down ozone and thereby damage the ozone layer in the
stratosphere, causing increased reception on earth of ultraviolet light
with increased risks e.g. skin cancer (malignant melanoma) as a
consequence.
Lead**
Lead can be found in picture tubes, display screens, solders and
capacitors. Lead damages the nervous system and in higher doses,
causes lead poisoning. The relevant TCO'99 requirement permits the
inclusion of lead since no replacement has yet been developed.
* Bio-accumulative is defined as substances which accumulate within
living organisms.
** Lead, Cadmium and Mercury are heavy metals which are bioaccumulative.
Energy Star Declaration

1. Safety Instructions for Repairs
1.1 Safety regulations require that during a repair:
- The set should be connected to the mains via an isolating
transformer.
- Safety components, indicated by the symbol, should be
replaced by components identical to the original ones.
- When replacing the CRT, safety goggles must be worn.
1.2 Safety regulations require also that after a repair:
- The set should be returned in its original condition.
- The cabinet should be checked for defects to avoid touching,
by the customer, of inner parts.
- The insulation of the mains lead should be checked for
external damage.
- The mains lead strain relief should be checked on its
function.
- The cable form and EHT cable are routed correctly and fixed
with the mounted cable clamps in order to avoid touching of
the CRT, hot components or heat sinks.
* Thermally loaded solder joints should be checked and
resoldered where necessary. This includes components like
LOT, the line output transistor, fly-back capacitor.
2. Maintenance Instructions
and on the picture tube panel.
3.4 Never replace modules or other components while the unit is
switched on.
3.5 When making settings, use plastic rather than metal tools.
This will prevent any short-circuit and the danger of a circuit
becomes unstable.
3.6 After repair the wiring should be fastened once more in the cable
clamps for this purpose.
3.7 Together with the deflection unit the picture tube is used as an
integrated unit. Adjustment of this unit during repair is therefore
not recommended.
4. Notes
The semiconductors indicated in the circuit diagram(s) and in the
parts lists are completely interchangeable per position with the
semiconductors in the unit, irrespective of the type indication on
these semiconductors.
It is recommended to have a maintenance inspection carried out
periodically by a qualified service employee. The interval depends on
the usage conditions.
- During the maintenance inspection the above mentioned "safety
instructions for repair" should be carried out The power supply and
deflection circuitry on the chassis, the CRT panel and the neck of
the CRT should be cleaned.
When cleaning the monitor on the outside:
- Always disconnect the monitor from the mains.
- Always use a damp AND NOT WET lint-free cloth.
- To clean the screen, apply a household glass cleaner to a cloth and
then wipe the screen.
- Do not use solvents or abrasives on the monitor.
It might discolour the cabinet and/or affect the anti glare treatment
on your screen.
3. Warnings
3.1 In order to prevent damage to ICs and transistors, all high-
voltage flash-overs must be avoided. In order to prevent damage to
the picture tube, the method shown in Fig 3.1 should be used to
discharge the picture tube. Use a high-voltage probe and a
multimeter (position DC-V). Discharge until the meter reading is 0V
(after approx 30s).
3.2ESD
V
Fig. 3.1
All ICs and many other semiconductors are sensitive to electrostatic
discharges (ESD). Careless handling during repair can drastically
shorten the life. Make sure that during repair you are connected by a
pulse band with resistance to the same potential as the earth of the
unit. Keep components and tools also at this same potential.
3.3 Be careful when taking measurements in the high-voltage section

When carry-out the electrical settings in many cases a video
signal must be applied to the monitor. A computer with :
- ATI GPT-1600 (4822 397 10065), Mach 64 (up to 107kHz)
are used as the video signal source. The signal patterns are
selected from the "service test software" package, see user
guide 4822 727 21046 (GPT-1600).

1. Purity adjustment
- Make sure the monitor is not exposed to any
external magnetic field.
- Produce a full red pattern on the screen, adjust the
purity magnet rings on the PCM assy (on CRT) to
obtain a complete field of the color red. This is done
by moving the two tabs (2-pole) in such a manner
that they advance in an opposite direction but at
the same time to obtain the same angle between
the two tabs, which should be approximately 180
degree.
- Check by full green pattern and full blue pattern
again to observe their respective color purity.
Introduction
Slight deviation in the static convergence can be
corrected by using two permanent pairs of magnets
which are fitted around the neck of the CRT. These
are the 4-pole magnet and the 6-pole magnet.
The 4-pole magnet move the outermost electron
beams (R and B) parallel in the opposite direction
from the other. The 6-pole magnet moves the
outermost electron beam (R, B and G) parallel in the
opposite direction from the other.
The magnetic field of the above magnets do not affect
the center of the CRT neck.
Setting
- Before the static convergence setting can be made,
the monitor must be switched on for 30 minutes.
- The focus setting must be made correctly.
- Signal: 640 * 480, 31.5 kHz/60 Hz mode.
- Set the tabs of the 4-pole magnet in the neutral
position. This is when the tabs are opposite one
another. In this position the magnets do not affect the
deflection of the R and B electron beams.
- Set the tabs of the 6-pole magnet in the neutral
position. This is when the tabs are opposite one
another. In this position the magnets do not affect the
deflection of the R, B, and G electron beams.
- First set the 4-pole magnet optimally.
- Then set the 6-pole magnet optimally.
- If the convergence is not now optimal, then adjust to
the optimal setting with the 4-pole magnet and then with
the 6- Pole magnet again.
- Set the tabs of the 6-pole magnet in the neutral
position. This is when the tabs are opposite one
another. In this position the magnets do not affect the
deflection of the R, B, and G electron beams.
- First set the 4-pole magnet optimally.
- Then set the 6-pole magnet optimally.
- If the convergence is not now optimal, then adjust to
the optimal setting with the 4-pole magnet and then
with the 6- pole magnet again.

All ICs and many other semi-conductors are susceptible to
electrostatic discharges (ESD). Careless handling during repair can
reduce life drastically. When repairing, make sure that you are
connected with the same potential as the mass of the unit via a wrist
wrap with resistance. Keep components and tools also at the same
potential !
1. Servicing of SMDs (Surface Mounted Devices)
1.1 General cautions on handling and storage
- Oxidation on the terminals of SMDs results in poor soldering. Do not
handle SMDs with bare hands.
- Avoid using storage places that are sensitive to oxidation such as
places with sulphur or chlorine gas, direct sunlight, high
temperatures or a high degree of humidity. The capacitance or
resistance value of the SMDs may be affected by this.
- Rough handling of circuit boards containing SMDs may cause
damage to the components as well as the circuit boards. Circuit
boards containing SMDs should never be bent or flexed. Different
circuit board materials expand and contract at different rates when
heated or cooled and the components and/or solder connections
may be damaged due to the stress. Never rub or scrape chip
components as this may cause the value of the component to
change. Similarly, do not slide the circuit board across any surface.
1.2 Removal of SMDs
- Heat the solder (for 2-3 seconds) at each terminal of the chip. By
means of litz wire and a slight horizontal force, small components
can be removed with the soldering iron. They can also be removed
with a solder sucker (see Fig. 1A)

solder the component on one side. Ensure that the component is
Positioned correctly on the solder lands (see Fig.2A).
- Next complete the soldering of the terminals of the component (see
Fig. 2B).

2. Caution when attaching SMDs
- When soldering the SMD terminals, do not touch them directly with
the soldering iron. The soldering should be done as quickly as
possible, care must be taken to avoid damage to the terminals of
the SMDs themselves.
- Keep the SMD's body in contact with the printed board when
soldering.
- The soldering iron to be used (approx. 30W)should preferably be
equipped with a thermal control (soldering temperature: 225 to 250
o
C).
- Soldering should not be done outside the solder land.
- Soldering flux (of rosin) may be used, but should not be acidic.
- After soldering, let the SMD cool down gradually at room
temperature.
- The quantity of solder must be proportional to the size of the solder
land. If the quantity is too great, the SMD might crack or the solder
lands might be torn loose from the printed board(see Fig. 3).

- While holding the SMD with a pair of tweezers, take it off gently
using the soldering iron's heat applied to each terminal (see Fig. 1
B).
- Remove the excess solder on the solder lands by means of litz wire
or a solder sucker (see Fig. 1C).
1.3 Caution on removal
- When handling the soldering.iron. use suitable pressure and be
careful.
- When removing the chip, do not use undue force with the pair of
tweezers.
- The soldering iron to be used (approx. 30 W) should
equipped with a thermal control (soldering temperature: 225 to 250
o
C).
preferably be
- The chip, once removed, must never be reused.
1.4 Attachment of SMDs
- Locate the SMD on the solder lands by means of tweezers and
