Precautions, Notes, and Abbreviation List
3.Precautions, Notes, and Abbreviation List
Index of this chapter:
3.1 Safety Instructions
3.2 Warnings
3.3 Notes
3.4 Abbreviation List
3.1Safety Instructions
Safety regulations require the following during a repair:
•Connect the set to the Mains/AC Power via an isolation
transformer (> 800 VA).
•Replace safety components, indicated by the symbol h,
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 Mains/AC Power cord for
proper function.
•Check the electrical DC resistance between the Mains/AC
Power plug and the secondary side (only for sets that have
a Mains/AC Power isolated power 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 M and 12 M.
4. Switch “off” the set, and remove the wire between the
two pins of the Mains/AC Power plug.
•Check the cabinet for defects, to prevent touching of any
inner parts by the customer.
3.2Warnings
•All ICs and many other semiconductors are susceptible to
electrostatic discharges (ESD w). Careless handling
during repair can reduce life drastically. Make sure that,
during repair, you are connected with the same potential as
the mass of the set by a wristband with resistance. Keep
components and tools also at this same potential.
•Be careful during measurements in the high voltage
section.
•Never replace modules or other components while the unit
is switched “on”.
•When you align the set, use plastic rather than metal tools.
This will prevent any short circuits and the danger of a
circuit becoming unstable.
3.3Notes
3.3.1 General
•Measure the voltages and waveforms with regard to the
chassis (= tuner) ground (H), or hot ground (I), depending
on the tested area of circuitry. The voltages and waveforms
shown in the diagrams are indicative. Measure them in the
Service Default Mode with a colour bar signal and stereo
sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and
picture carrier at 475.25 MHz for PAL, or 61.25 MHz for
NTSC (channel 3).
•Where necessary, measure the waveforms and voltages
with (D) and without (E) aerial signal. Measure the
voltages in the power supply section both in normal
operation (G) and in stand-by (F). These values are
indicated by means of the appropriate symbols.
3.3.2Schematic Notes
•All resistor values are in ohms, and the value multiplier is
often used to indicate the decimal point location (e.g. 2K2
indicates 2.2 k).
•Resistor values with no multiplier may be indicated with
either an “E” or an “R” (e.g. 220E or 220R indicates 220 ).
•All capacitor values are given in micro-farads (10
nano-farads (n 10
•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 on the Philips
Spare Parts Web Portal.
3.3.3Spare Parts
For the latest spare part overview, consult your Philips Spare
Part web portal.
3.3.4BGA (Ball Grid Array) ICs
Introduction
For more information on how to handle BGA devices, visit this
URL: http://www.atyourservice-magazine.com
“Magazine”, then go to “Repair downloads”. Here you will find
Information on how to deal with BGA-ICs.
BGA Temperature Profiles
For BGA-ICs, you must use the correct temperature-profile.
Where applicable and available, this profile is added to the IC
Data Sheet information section in this manual.
3.3.5Lead-free Soldering
Due to lead-free technology some rules have to be respected
by the workshop during a repair:
•Use only lead-free soldering tin. 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 avoided 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 stabilize the adjusted temperature 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 stabilized at the solder joint.
Heating time of the solder-joint should not exceed ~ 4 sec.
Avoid temperatures above 400°C, otherwise wear-out of
tips will increase drastically and flux-fluid will be destroyed.
To avoid wear-out of tips, switch “off” unused equipment or
reduce heat.
•Mix of lead-free soldering tin/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.
3.3.6Alternative BOM identification
It should be noted that on the European Service website,
“Alternative BOM” is referred to as “Design variant”.
The third digit in the serial number (example:
AG2B0335000001) indicates the number of the alternative
B.O.M. (Bill Of Materials) that has been used for producing the
specific TV set. In general, 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 suppliers. This will then

Precautions, Notes, and Abbreviation List
result in sets which have the same CTN (Commercial Type
Number; e.g. 28PW9515/12) but which have a different B.O.M.
number.
By looking at the third digit of the serial number, one can
identify which B.O.M. is used for the TV set he is working with.
If the third digit of the serial number contains the number “1”
(example: AG1B033500001), then the TV set has been
manufactured according to B.O.M. number 1. If the third digit is
a “2” (example: AG2B0335000001), then the set has been
produced according to B.O.M. no. 2. This is important for
ordering the correct spare parts!
For the third digit, the numbers 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.
Identification: The bottom line of a type plate gives a 14-digit
serial number. Digits 1 and 2 refer to the production centre (e.g.
SN is Lysomice, RJ is Kobierzyce), digit 3 refers to the B.O.M.
code, digit 4 refers to the Service version change code, digits 5
and 6 refer to the production year, and digits 7 and 8 refer to
production week (in example below it is 2010 week 10 / 2010
week 17). The 6 last digits contain the serial number.
Figure 3-1 Serial number (example)
3.3.7Board 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 defective board. Otherwise, it
cannot be returned to the O.E.M. supplier for back charging!
3.3.8 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.

For easy servicing of a TV set, the set should be put face down
on a soft flat surface, foam buffers or other specific workshop
tools. Ensure that a stable situation is created to perform
measurements and alignments. When using foam bars take
care that these always support the cabinet and never only the
display. Caution: Failure to follow these guidelines can
seriously damage the display!
Ensure that ESD safe measures are taken.
Instructions below apply to the 32PHT5109/98, but will be
similar for other 32"/40"/50"PxT5109 series models.

Service Modes and Fault Finding
5.Service Modes and Fault Finding
Index of this chapter:
5.1 Test Points
5.2 Service Modes
5.3 Stepwise Start-up
5.4 Software Upgrading
5.5 Fault Finding and Repair Tips
5.1Test Points
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope.
Perform measurements under the following conditions:
•Service Default Mode.
•Video: Colour bar signal.
•Audio: 3 kHz left, 1 kHz right.
5.2Service Modes
The Service Mode feature is split into five parts:
•Factory Mode.
•Customer Service Mode (CSM).
The Factory mode offer features, which can be used by the
Service engineer to repair/align a TV set. Some features are:
•Make alignments (e.g. White Tone), reset the error buffer
(Factory Mode).
The CSM is a Service Mode that can be enabled by the
consumer. The CSM displays diagnosis information, which the
customer can forward to the dealer or call centre. In CSM
mode, “CSM”, is displayed in the top right corner of the screen.
The information provided in CSM and the purpose of CSM is to:
•Increase the home repair hit rate.
•Decrease the number of nuisance calls.
•Solved customers’ problem without home visit.
EN 23TPS14.2A LA5.
Software Identification, Version, and Cluster
The software ID and version will be shown in the main menu
display of CSM.
The screen will show: “AAAAB-X.YYY”, where:
•AAAA is the chassis name: TPS142A x.yyy.
•B is the region indication: E = Europe, A = AP/China, U =
NAFTA, L = LATAM.
•X is the main version number: this is updated with a major
change of specification (incompatible with the previous
software version). Numbering will go from 1 - 99 and
AA - ZZ.
- If the main version number changes, the new version
number is written in the NVM.
- If the main version number changes, the default settings
are loaded.
•YYY is the sub version number: this is updated with a minor
change (backwards compatible with the previous
versions). Numbering will go from 000 - 999.
- If the sub version number changes, the new version
number is written in the NVM.
- If the NVM is refreshed, the software identification,
version, and cluster will also be written to NVM.
5.2.2Contents of the Factory mode:
Purpose
•To perform extended alignments.
Specifications
•Displaying and or changing Panel ID information.
•Various software alignment settings.
•Testpattern displaying.
•Public Broadcasting Service password Reset.
•etc.
Note: For the new model range, a new remote control (RC) is
used with some renamed buttons. This has an impact on the
activation of the Service modes. For instance the old “MENU”
button is now called “HOME” (or is indicated by a “house” icon).
How to Activate the Factory mode
To activate the Factory mode, use the following method:
•Press the following key sequence on the remote control
transmitter: “Menu+1999+Back/Recall”. Do not allow the
display to time out between entries while keying the

Note:
•Do not remove the USB flash drive during the software
update.
•Do not turn off the power during the software update.
•If a power failure occurs during the update, do not remove
the USB flash drive from the TV. The TV will continue the
software update as soon as the power comes up again.
•If an error occurs during the update retry the procedure or
contact the dealer.
•We do not recommend downgrading to an older version.
•Once the upgrade is finished, use the PC to remove the TV
software from the USB portable memory.
5.5.2TV Will Not Start-up from Stand-by
Possible Stand-by Controller failure. Re-flash the software.
5.5.3Audio Amplifier
The Class D-IC U602 has a powerpad for cooling. When the IC
is replaced it must be ensured that the powerpad is very well
pushed to the PWB while the solder is still liquid. This is needed
to insure that the cooling is guaranteed, otherwise the Class
D-IC could break down in short time.
5.5.4 CSM
When CSM is activated and there is a USB memory stick
connected to the TV, the software will dump the complete CSM
content to the USB memory stick. The file (Csm.txt) will be
saved in the root of the USB memory stick.
5.5.5Loudspeakers
Make sure that the volume is set to minimum during
disconnecting the speakers in the ON-state of the TV. The
audio amplifier can be damaged by disconnecting the speakers
during ON-state of the set!
5.5.6Display option code
Attention: In case the SSB is replaced, always check the Panel
Code in CSM, even when picture is available. Performance
with the incorrect display option code can lead to unwanted
side-effects for certain conditions.
5.4.6Content and Usage of the One-Zip Software File
Below you find a content explanation of the One-Zip file, and
instructions on how and when to use it. Only files that are
relevant for Service are mentioned here.
