2. Precautions, Notes, and Abbreviation List

tools. This will prevent any short circuits and the danger

of a circuit becoming unstable.

2.1 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 

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.

2.2 Warnings

 All ICs and many other semiconductors are susceptible

to electrostatic discharges (ESD ). 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

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 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 ( ) 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 appropriate symbols.

2.3.2 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 (µ = x10

nano-farads (n = x10

-9

), 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 on the Philips

Spare Parts Web Portal.

2.3.3 Spare parts

For the latest spare part overview, consult your Philips

Spare Part web portal.

2.3.4 BGA (Ball Grid Array) ICs

Introduction

For more information on how to handle BGA devices, visit

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

“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

-12

Select

-6

IC Data Sheet information section in this manual.

2.3.5 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.

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.

2.3.6 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 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!

Figure 3-1 Serial number (example)

2.3.7 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!

2.3.8 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.

 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.

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. Software Upgrading, Error code and Panel Code

5.1 Software Upgrading

Step 1: Ready for F/W Upgrade

1. Rename the software as “autorun.upg”.

Prepare a USB memory (File format: FLAT, Size: 1G~8G).

3. Copy the software to USB flash disk (root directory).

Note the version of this F/W before you change the software file name.

Step 2: F/W Upgrade

1. Plug the USB memory on the USB port on the side I/O port of TV (Please connect to USB 2.0 port, not recommend USB 3.0 port.).

AC on (Power plug).

3. TV will take a few minutes the downloading to detect the software, and then upgrade automatically as detect the software

4. Press OK to start software upgrade

5. Upgrade in progress

Step 3: Check the SW version

1. After burning software, TV will restart.

Press “123654”, enter Customer Service Mode to check if the software version is correct.

Caution: Please make sure that software upgrade is finished before unplug the USB and AC power!

5.2 Error Code

5.2.1 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 I2C device.

• General I2C 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.

5.2.2 How to Read the Error Buffer

You can read the error buffer in below 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).

5.2.3 Error codes overview

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:

5.2.4 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.

5.3 Set Option Code

For all models of TPM18.1E_LA chassis, a SET OPTION code is used instead of the DISPLAY OPTION code.

The Set Option Code feature allows using one single Set Option number to define all settings for a specific TV set type.

5.3.1 Where to find the Set Option Code

Refer to the stickers on the TV set. The Set Option Code (three digit decimal value), Set type and Production code can be read from two stickers matching

the TV set:

- Family sticker, stuck on the Back Cover:

- Set Option code sticker, in general, stuck on the Deco frame:

5.3.2 How to set the Set Option Code after SSB Replacement

1. Take note of the Set Option Code of the TV set. Set Option Code, Set type and Production code can be read from two stickers on the TV set.

2. Switch “ON” the TV set.

The modified TV set should start up with the default values.

3. Enter the Set Option Code.

Using a standard remote control, successively press: “062598” + MEMU/HOME + “xxx”,

- with “xxx” is the three digit decimal value of a valid Set Option Code (See below table), corresponding with the modified TV set, and MEMU/HOME is the

button with the home icon.

Result:

After accepting the Set Option Code the TV set stores the following items in NVM:

- the TV Set type (Model Number),

- the related option codes, and the default White Point values.

Then the TV set switches to Stand-by to indicate the process is completed.

Note:

Entering a non existing Set Option Code has no effect.

4. Use remote control to switch “ON” the TV set.

5. Use SAM mode to check the Set type (Model number) in NVM and to manually correct if it is wrong.

6. Optionally, check other TV-related items present in NVM and manually adapt them via SAM:

- TV Production code (Serial number on stickers),

- 18 AC of replacement SSB (see bar code sticker on SSB),

- 18 AC of actual Power Supply Unit (see bar code sticker on PSU board),

- 18 AC of actual Display Panel.

Result:

After leaving the SAM mode, the TV set should switch to Standby. The NVM should contain the correct option codes, TV related items and default White

Point values.
