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 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.

3.3.3 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 “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

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.

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 Service 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.

5.2 Stepwise Start-up

5.3 Service Tools

5.4 Software Upgrading

5.5 Error Codes

5.6 The Blinking LED Procedure

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).

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.

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: TPN162E 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.

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

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

• General I 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).

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.

Figure 5-5 Error code overview

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 lay er 1 error(s), this works in “normal operation” mode or automatically when the error/protection is monitored by the standby processor. In case no picture is shown and there is no LED blinking, read the logging to detect whether “error devices” are mentioned. (see section “5.7 Fault Finding and Repair

Tips, 5.7.4 Guidelines Uart logging”).

• Activate SAM. The blinking front LED will show the entire content of the LAYER 2 error buffer, this works in “normal operation” mode.

Service Modes, Error Codes, and Fault Finding

EN 21TPN16.2E LA 5.

5.7 Fault Finding and Repair Tips

Note:

• It is assumed that the components are mounted correctly with correct values and no bad solder joints.

• Before any fault finding actions, check if the correct options are set.

5.7.1 NVM Editor

In some cases, it can be convenient if one directly can change the NVM contents. This can be done with the “NVM Editor” in SAM mode. With this option, single bytes can be changed.

Caution:

• Do not change these, without understanding the function of each setting, because incorrect NVM settings may seriously hamper the correct functioning of the TV set!

• Always write down the existing NVM settings, before changing the settings. This will enable you to return to the original settings, if the new settings turn out to be incorrect.

5.7.2 CSM

When CSM is activated and there is an USB stick connected to the TV set, then the software will collect the complete CSM content in a file Csm.xml and dump the file in a folder “CSM” on the USB stick. When this mechanism works it can be concluded that a large part of the operating system is already working (SOC, USB ...).

5.7.8 Audio Amplifier

The Class D-IC U606 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.

5.7.9 Loudspeakers

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!

5.7.10 Display 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.

5.7.3 No Picture

When you have no picture, first make sure you have entered the correct display code. See paragraph 6.4 Option Settings

the instructions. See also Table 6-3

5.7.4 Guidelines Uart logging

Possible cases:

Uart loggings are displayed:

• We can conclude that the TV-set is starting up and thatcommunication with the flash RAM seems to be supported. The processor is able to read and write in the DRAMs.

• We can not yet conclude that flash RAM and DRAMs are fully operational/reliable.There still can be errors in the data transfers, DRAM errors, read/write speed and timing control.

Uart loggings report fault conditions, error messages, error codes and fatal errors:

• Some failures are indicated by error codes in the logging, check referring to figure 5-5 Error code overview

•I

2C bus errors.

• Not all failures or error messages should be interpreted as fault. For instance the root cause can be wrong option codes settings.

5.7.5 Unstable Picture via HDMI input

for

Check if HDMI EDID data is properly programmed.

5.7.6 No Picture via HDMI input

Check if HDCP key is valid. This can be done in CSM.

5.7.7 TV Will Not Start-up from Stand-by

6.1 General Alignment Conditions

Perform all electrical adjustments under the following conditions:

• Power supply voltage: 90 - 264 V

• Connect the set to the mains via an isolation transformer with low internal resistance.

• Allow the set to warm up for approximately 15 minutes.

• Measure voltages and waveforms in relation to correct ground (e.g. measure audio signals in relation to AUDIO_GND). Caution: It is not allowed to use heat sinks as ground.

• Test probe: R

> 10 MW, Ci < 20 pF.

• Use an isolated trimmer/screwdriver to perform alignments.

, 50/ 60 ± 3 Hz.

Alignments

In case you have a colour analyser:

• Measure with a calibrated (phosphor- independent) color analyser (e.g. Minolta CA-210) in the centre of the screen. Consequently, the measurement needs to be done in a dark environment.

• Adjust the correct x, y coordinates (while holding one of the White point registers R, G or B on max. value) by means of decreasing the value of one or two other white points to the correct x, y coordinates (see Table 6-1 White D alignment

values). Tolerance: dx: ± 0.003, dy: ± 0.003.

• Repeat this step for the other colour Temperatures that need to be aligned.

• When finished return to the SAM root menu and press STANDBY on the RC to store the aligned values to the NVM.

6.3 Software Alignments

Put the set in SAM mode (see Chapter 5. Service Modes, Error

Codes, and Fault Finding). The SAM menu will now appear on

the screen. Select RGB Align and go to one of the sub menus. The alignments are explained below. The following items can be aligned:

• White point.

To store the data:

• Press OK on the RC before the cursor is moved to the left.

• Select “Store” and press OK on the RC.

• Switch the set to stand-by mode.

For the next alignments, supply the following test signals via a video generator to the RF input:

• EU/AP-PAL models: a PAL B/G TV-signal with a signal strength of at least 1 mV and a frequency of 475.25 MHz

• US/AP-NTSC models: an NTSC M/N TV-signal with a signal strength of at least 1 mV and a frequency of

61.25 MHz (channel 3).

• LATAM models: an NTSC M TV-signal with a signal strength of at least 1 mV and a frequency of

61.25 MHz (channel 3).

6.3.1 RGB Alignment

Before alignment, set the picture as follows:

Picture Setting

Dynamic backlight Off Dynamic Contrast Off Color Enhancement Off Picture Format Unscaled Light Sensor Off Brightness 50 Color 0 Contrast 100

White Tone Alignment:

• Activate SAM.

• Select “RGB Align.” and choose a color temperature.

• Use a 100% white screen as input signal and set the following values: – “Red BL Offset” and “Green BL Offset” to “7” (if

present).

– All “White point” values initial to “128”.

If you do not have a colour analyser, you can use the default values. This is the next best solution. The default values are average values coming from production (statistics).

6.3.2 Display Adjustment

You can use the default values. The default values are average values coming from production.

• Enter SAM mode.

• Select a colour temperature (e.g. COOL, NORMAL, or WARM).

• Set the RED, GREEN and BLUE default values according to the values in Table 6-2

• When finished press OK on the RC, then press STORE to store the aligned values to the NVM.

• Restore the initial picture settings after the alignments.

6.4 Option Settings

6.4.1 Introduction

The microprocessor communicates with a large number of I ICs in the set. To ensure good communication and to make digital diagnosis possible, the microprocessor has to know which ICs to address. The presence / absence of these MT5561 ICs is made known by the option codes.

Notes:

• After changing the option(s), save them by pressing the OK button on the RC before the cursor is moved to the left, select STORE and press OK on the RC.

• The new option setting is only active after the TV is switched “off” / “stand-by” and “on” again with the mains switch (the NVM is then read again).

6.4.2 Option Code Overview

Enter SAM mode to check the option codes. they could be edited in the NVM.

6.4.3 Display Code Overview

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: see column “Display Code” in Table 6-3

6.5 Reset of Repaired SSB

A very important issue towards a repaired SSB from a Service repair shop (SSB repair on component level) implies the reset of the NVM on the SSB. A repaired SSB in Service should get the service Set type “00PF0000000000” and Production code “00000000000000”. Also the virgin bit is to be set. To set all this, you can use the “NVM editor” and “Dealer options” items in SAM (do not forget to “store”).

After a repaired SSB has been mounted in the set (set repair on board level), the type number (CTN) and production code of the TV has to be set according to the type plate of the set. For this, you can use the NVM editor in SAM.

In case of a display replacement, reset the “Operation hours display” to “0”, or to the operation hours of the replacement display. Remark:

- After the NVM has been replaced, go to SAM and scroll to the <Reload MAC address> (see figure 1*).

- Select the item and press <OK> on the RC.

6.5.1 Reset of Repaired SSB

Instruction

After NVM replacement, reload MAC address via SAM menu.This ensures the correct MAC address to be available in CSM for future repair actions.

Way of working:

• After the NVM has been replaced, go to SAM and scroll to the <Reload MAC address> .

• Select the item and press <OK> on the RC.

Notes:

• Only applicable to all related models that are “Smart TV level 0”enabled (only YouTube access). For models

without internet connection feature, no action is needed.

• HDCP keys are located in the NVM.

New NVM EEPROMs are shipped with pre-loaded HDCP keys.

6.5.2 SSB Identification

SSB’s of this chassis are identified by a “715” code on the SSB. 715Axxxx-Nnn-MMM-OOOO

• 715 main category, Printed Wiring Board

• Axxxx sub category, sequential coding number

• Nnn Version code

• N Development number

• nn Production number

• MMM Mounting variation code

• OOOO Optional variation code

Make sure when replacing an SSB the SSB identification codes match the replacement panel.

6.6 Cable position numbers

In this chassis, the cable position numbers can be defined via the rule that the number is always starting with an “E” followed by the connector number of the current sourcing board. The order is always seen from where the power initiates from. So from PSU to SSB, from SSB to IR/LED panel, from IR/LED panel to keyboard control panel. For example, a cable from the PSU connector CN902 to the SSB connector CN701, will have the position number ECN902.
