Index of this chapter:

2.1 Safety instructions

2.3 Notes

2.1 Safety Instructions

Safety regulations require the following during a repair:

·

Connect set to the Mains/AC Power via an isolation
transformer(>800VA)

·

Replace safety components,indicated by the symbol ,
only by components identical to the original ones.Any
other component substitution(other than original type)may

increase risk of fire or electrical shock hazard

Safety regulations require that after a repair,the set must
be returned in its original condition.pay in particular

attention to the following points:

·

Route the wire trees correctly and fix them with the

mounted cable clamps.

·

Check the insulation of the Mains/AC power lead
for external damage.

·

Check the strain relief of the Main/AC power cord

for proper function.

Check the electrical DC resistance between the pins of

·

the Mains/AC Power plug and secondary side(only for
sets that have a Mains/AC power isolated poer supply):

1. Unplug the Mains/AC Power cord and connect a wire
between the two pins of the Mains/AC power plug.\

2.Set the Mains/AC Power switch to the ON position
(keep the Mains/AC Power cord unplugged!)

3.Measure the resistance value between the pins of the
Mains/AC Power plug and the metal shielding of the
tuner or the aerial connection on the set.The reading
should be between 4.5 Mohm and 12 Mohm.

4.Switch OFF the set,and remove the wire between

Check the cabinet for defects,to prevent touching of any inner

·

parts by the customer.

""

the two pins of the Mains/AC plug.

""

·

Where necessary,measure the waveforms and voltages with( )
and without( )aerial signal.Measure the voltages in the power

supply section both in normal operation( ) and in stand-by( ).

These values are indicated by means of the approprate symbols.

·

The semiconductors indicated in the circuit diagram and in the
parts lists,are interchangeable per position with the
semiconductors in the unit,irrespective of the type indication
on these semiconductors.

2.3.2 Schematic Notes

·

All resistor values are ohms,and the value multiplier is often used
to indicate the decimal point location(e.g. 2K2 indicates 2.2 kohm).

·

Resistor values with no munltiplier may be indicated with either an

E or an R (e.g.220E or 220R indicates 220 ohm).

"" ""

·

All capacitor values are given in micro-farads(u=x10 ),nano­farads9n=x10 ),or pico-farads(p=x10 ).

·

Capacitor values may also use the value multiplier as the decimal

point indication(e.g. 2p2 indicates 2.2 pF).

·

An asterisk (*) indicates component usage varies.Refer to the

""

diversity tables for the correct values.

·

The correct component values are listed in the Spare Parts List.
Therefore,always check this list when there is amy doubt.

2.3.3 Lead-free Solder

Philips CE is producing Lead-free sets (PBF) from 1.1.2005
onwards.

Idntification:The bottom line of a type gives a 14-digit serial
number.Digial 5 and 6 refer to the production year,digits 7 and
8 refer to production week( inexample below it is 2007 week14)

2.2 Warnings

·

All ICs and many other semiconductors are susceptible to
electrostatic discharges(ESD ).Careless handling during
repair can redure life drastically.Make sure that,during repair,
you are connected with same potential as the mass of the set
by wristband ith resistance .Keep components and tools also

at this same potential.Available EDS protection equipment:

-Complete kitEDS3(small tablemat,wrisband,connection box
,extension cable and earth cable)4822 310 10671.

-Wristband tester 4822 344 13999.

·

Be careful suring measurements in the high voltage section.

·

Never replace modues or other components while the unit
is switched ON .

·

When you align the set,use plastic rather than metal tools.This
will prevent any shurt circuits and danger of a circuit becoming

unstable.

2.3 Notes

2.3.1 General

Measure the voltages and waveforms with regard to the chassis

·

(=tuner)ground( ),or hot ground( ), depending on the tested area
of curcuitry.The voltages and waveforms shown in the diagrams

are indicative.Measure them in the Service Default Mode(see

chapter 5)with a colour bar signal and stereo sound(L:3 khz,
R:1 kHz unless statedotehrwise)and picture carrier at 475.25
Mhz for PAL,or 61.25 MHZ for NTSC(channel 3).

2. Safety Instructions,Warnings and Notes

TPS 1.0A LA

Use only lead-free soldering tin Philips SAC305 with
order code 06622 149 00106.If lead-free solder paste
is required please contact the manufacturer of your
soldering equipment.In general,use of solder paste
within workshops should be avioded because paste is not

easy to store and to handle.
Use only adequate solder tools applicable for lead-free
soldering tin.The solder tool must be able:

-To reach a solder-tip temperature of at least 400 C.

-To stabilise the adjusted temerature at the solder-tip

-To exchange solder-tips for different applications.
Adjust your solder tool so that a temperature of around
360 C -380 C is reached and stablilised at the solder joint.
Heating time of the solder-joint should not exceed~4sec.
Aviod temperatures above 400 C,otherwise wear-out of tips
will increase drastically and flux-fluid will be destroyed.
To aviod wear-out of tips,switch”off” unused equipment or
reduce heat.
Mix of lead-free soldering tim/parts with leaded soldering
tin/parts is possible but PHILIPS recommends strongly to
avoid mixed regimes.If this cannot be avoided,carefully
clear the solder-joint from old tin and re-solder with new
tin.
Use only original spare -parts listed in the Service-Manuals.
Not listed standed material(commodities)has to be purchased
at external companies.
For sets produced before 1.1.2005,containing leaded
soldering tin and components,all needed spare parts will
be available till the end of the service period.For the
repair of such sets nothing changes

Alternativ BOM(bill of Materials used for producing the sepcific
model of TV set).It is possible that the same TV model on the
market is produced with e.g. Two different types of displays,
coming from two different O.E.M.s.
By looking at the third digit of the serial number,the serivce
technician can see if there is more than one type of B.O.M. Used
in theproduction of the TV set he is working with.He can used in
the Commercial type Version Number of the TV set
(e.g.20PFL4122/93),after which a screen will appear that gives
information about the number of alternative B.O.M.s used.
If the third digit of serial nuber contains the number 1(example:
AG1B0335000001),then there is only one B.O.M. Version of the

TV set on the market.If tje third digit is a 2(example:
AG2B033500001),then there are two different B.O.M.s.
Information about this is important for ordering the correct spare
parts!

For the third digit,the number 1....9 and the characters A.....Z can

be used,so in total:9 plus 26=35 different B.O.M.s can be indicated
by the third digit of the serial number.

2.3.5 Board Level repair(BLR) or Component Level Repair(CLR)

If a board is defective,consult your repair procedure to decide if
the board has to be exchanged or if it should be repaired on
component level.
If your repair procedure says the board should be exchanged
completely,do not solder on the degective board.Otherwise,it
cannot be returned to the O.E.M. Supplier for back charging!

In case of doubt whether the board is lead-free or not(or
with mixed technologies),you can use the following method:

Always use the highest temperature to solder,when using
SAC305(see also instructions below).
De-solder thoroughly(clean solder joints to avoid mix of
two alloys).

2.3.4 Alternative BOM identification

In September 2005,Philips CE introduced a change in the way
the serial number(or production number,see Figure 2-1)is
composed.From this data on,the third digit in the serial number
(example:AG2B0335000005) indicates the number of the

2.3.6 Practical Service precautions

It makes sense to avoid exposure to electrical shock.
While some sources are expected to have a possible dangerous
impact,others of quite high potential are of limited current and are
sometimes held in less regard.
Always respect voltages.While some may not be dangerous in
themselves,they can cause unexpected reactions that are best
avoided.Before reaching into a powered TV set,it is best to test
the high voltage insulation.It is easy to do,and is a good service
precaution.
