3. Precautions, Notes, and Abbreviation List

Index of this chapter:

3.1 Safety Instructions

3.2 Warnings

3.3 Notes

3.4 Abbreviation List

3.1 Safety 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.

3.2 Warnings

• 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.

3.3 Notes

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.

3.3.2 Schematic 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

-6

nano-farads (n 10

-9

), or pico-farads (p 10

-12

• 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.

3.3.3 Spare Parts

For the latest spare part overview, consult your Philips Spare

Part web portal.

3.3.4 BGA (Ball Grid Array) ICs

Introduction

For more information on how to handle BGA devices, visit this

URL: http://www.atyourservice-magazine.com

. Select

“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.

3.3.5 Lead-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.

3.3.6 Alternative 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

back to

div. table

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)

3.3.7 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 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.

4.2 Se rvice Positions

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.

5.7 Fault Finding and Repair Tips

5.1 Service Modes

The Service Mode feature is split into follow parts:

• Service Alignment Mode (SAM).

• Factory Mode.

• Customer Service Mode (CSM).

SAM and 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

(SAM and Factory Mode).

• Display information (“SAM” indication in upper right corner

of screen, error buffer, software version, operating hours,

options and option codes, sub menus).

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.

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).

5.1.1 General

Next items are applicable to all Service Modes or are general.

Life Timer

During the life time cycle of the TV set, a timer is kept (called

“Op. Hour”). It counts the normal operation hours (not the

Stand-by hours). The actual value of the timer is displayed in

SAM in a decimal value. Every two soft-resets increase the

hour by + 1. Stand-by hours are not counted.

Software Identification, Version, and Cluster

The software ID, version, and cluster will be shown in the main

menu display of SAM and CSM.

The screen will show: “AAAAB-X.YYY”, where:

• AAAA is the chassis name: TPN161E x.yy.

• 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.

Display Option Code Selection

When after an SSB or display exchange, the display option

code is not set properly, it will result in a TV with “no display”.

Therefore, it is required to set this display option code after

such a repair.

To do so, press the following key sequence on a standard RC

transmitter: “062598” directly followed by MENU and “xxx”,

where “xxx” is a 3 digit decimal value of the panel type. When

the value is accepted and stored in NVM, the set will switch to

Stand-by, to indicate that the process has been completed.

During this algorithm, the NVM-content must be filtered,

because several items in the NVM are TV-related and not SSB

related (e.g. Model and Prod. S/N). Therefore, “Model”

and “Prod. S/N” data is changed into “See Type Plate”. In case

a call centre or consumer reads “See Type Plate” in CSM

mode.

5.1.2 Service Alignment Mode (SAM)

Purpose

• To modify the NVM.

• To display/clear the error code buffer.

• To perform alignments.

Specifications

• Operation hours counter (maximum five digits displayed).

• Software version, error codes, and option settings display.

• Error buffer clearing.

• Option settings.

• Software alignments (White Tone).

• NVM Editor.

• Set screen mode to full screen (all content is visible).

How to Activate SAM

To activate SAM, use one of the following methods:

• Press the following key sequence on the remote control

transmitter: “062596”, directly followed by the “INFO/OK”

button. Do not allow the display to time out between entries

while ke

ying the sequence.

After entering SAM, the following items are displayed,

with “SAM” in the upper right corner of the screen to indicate

that the television is in Service Alignment Mode.

downloaded which is needed to upgrade the TV main

software and the software download application.

• NVM_clustername_version.zip: Default NVM content.

5.4.7 How to Copy NVM Data to/from USB

When copying data to and from a USB memory stick, the folder

“repair” is used. When inserting an empty USB memory stick,

and downloading data to the stick, the TV will create this folder.

When sending data from a USB memory stick to a TV, the

intended data must be available in the “repair” folder.

Note that when copying EDID data to the TV, all necessary

EDID files must be in this folder.

Service mode overview for your reference.

Table 5-3 Service mode overview

5.5 Error Codes

5.5.1 Introduction

Error codes are required to indicate failures in the TV set. In

principle a unique error code is available for every:

• Activated (SW) protection.

• Failing I

C device.

• General I

C error.

The last five errors, stored in the NVM, are shown in the

Service menu’s. This is called the error buffer.

The error code buffer contains all errors detected since the last

time the buffer was erased. The buffer is written from left to

right. When an error occurs that is not yet in the error code

buffer, it is displayed at the left side and all other errors shift one

position to the right.

An error will be added to the buffer if this error differs from any

error in the buffer. The last found error is displayed on the left.

An error with a designated error code never leads to a

deadlock situation. It must always be diagnosable (e.g. error

buffer via OSD or blinking LED).

In case a failure identified by an error code automatically

results in other error codes (cause and effect), only the error

code of the MAIN failure is displayed.

5.5.2 How to Read the Error Buffer

You can read the error buffer in three ways:

• On screen via the SAM/CSM (if you have a picture).

Example:

– ERROR: 000 000 000 000 000: No errors detected

– ERROR: 013 000 000 000 000: Error code 13 is the

last and only detected error

– ERROR: 034 013 000 000 000: Error code 13 was

detected first and error code 34 is the last detected

(newest) error

• Via the blinking LED procedure (when you have no

picture). See paragraph 5.6 The Blinking LED Procedure

5.5.3 Error codes

In this chassis only “layer 2” error codes are available and point

to problems on the SSB. They are triggered by LED blinking

when CSM is activated. Only the following layer 2 errors are

defined:

Table 5-4 Error code table

5.5.4 How to Clear the Error Buffer

The error code buffer is cleared in the following cases:

• By using the CLEAR command in the SAM menu

• By using the CLEAR command in the Factory mode:

• By using the following key sequence on the remote control

transmitter: “062599” directly followed by the OK button.

• If the contents of the error buffer have not changed for 50

hours, the error buffer resets automatically.

Note: If you exit SAM by disconnecting the mains from the

television set, the error buffer is not reset.

5.6 The Blinking LED Procedure

5.6.1 Introduction

The software is capable of identifying different kinds of errors.

Because it is possible that more than one error can occur over

time, an error buffer is available, which is capable of storing the

last five errors that occurred. This is useful if the OSD is not

working properly.

Errors can also be displayed by the blinking LED procedure.

The method is to repeatedly let the front LED pulse with as

many pulses as the error code number, followed by a period of

1.5 seconds in which the LED is “off”. Then this sequence is

repeated.

Example (1): error code 4 will result in four times the sequence

LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After

this sequence, the LED will be “off” for 1.5 seconds. Any RC

command terminates the sequence. Error code LED blinking is

in red color.

Example (2): the content of the error buffer is “12 9 6 0 0” After

entering SAM, the following occurs.

• 1 long blink of 5 seconds to start the sequence.

• 12 short blinks followed by a pause of 1.5 seconds.

• 9 short blinks followed by a pause of 1.5 seconds.

• 6 short blinks followed by a pause of 1.5 seconds.

• 1 long blink of 1.5 seconds to finish the sequence.

• The sequence starts again with 12 short blinks.

5.6.2 How to Activate Blinking LED Procedurer

Use one of the following methods:

• Activate CSM.The blinking front LED will show the layer 1

error(s), this works in “normal operation” mode or
