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

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)

3.3.7 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.

5.4 Service Tools
5.5 Software Upgrading

5.8 Fault Finding and Repair Tips
5.1 Test Points
As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. However, several key ICs are capable of generating test patterns, which can be controlled via ComPair. In this way it is possible to determine which part is defective.
Perform measurements under the following conditions:
Service Default Mode.
Video: Colour bar signal.
Audio: 3 kHz left, 1 kHz right.
5.2 Service Modes
The Service Mode feature is split into five parts:
Service Alignment Mode (SAM).
Factory Mode.
Customer Service Mode (CSM).
Computer Aided Repair Mode (ComPair).
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.
ComPair Mode is used for communication between a computer and a TV on I engineer to quickly diagnose the TV set by reading out error codes, read and write in NVMs, communicate with ICs and the micro processor (PWM, registers, etc.), and by making use of a fault finding database. It will also be possible to up and download the software of the TV set via I ComPair. To do this, ComPair has to be connected to the TV set via the ComPair connector, which will be accessible through the rear of the set (without removing the rear cover).
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).

5.2.1 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
2
C /UART level and can be used by a Service
2
C with help of
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: QN142A 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: see column “Display Code” in back to div. table 6-3 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.

5.2.2 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).

5.4 Service Tools

5.4.1 ComPair

Introduction
ComPair (Computer Aided Repair) is a Service tool for Philips Consumer Electronics products. and offers the following:
1. ComPair helps to quickly get an understanding on how to repair the chassis in a short and effective way.
2. ComPair allows very detailed diagnostics and is therefore capable of accurately indicating problem areas. No knowledge on I because ComPair takes care of this.
3. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the micro processor is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.
Specifications
ComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The ComPair II interface box is connected to the PC via an USB cable. For the TV chassis, the ComPair interface box and the TV communicate via a bi-directional cable via the service connector(s). The ComPair fault finding program is able to determine the problem of the defective television, by a combination of automatic diagnostics and an interactive question/answer procedure.

5.5.7 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.

5.6 Error Codes

5.6.1 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 or via ComPair). 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.

5.6.2 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).
2
C device.
2
C error.
Example: – ERROR: 000 000 000 000 000: No errors detectedERROR: 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

Service Modes and Fault Finding
Via the blinking LED procedure (when you have no picture). See paragraph 5.7 The Blinking LED Procedure
•Via ComPair.

5.6.3 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
Layer-2 error code Defective device
13 General I2C bus error on the SSB 16 +12 V mi ssing or low, PSU defective 27 Channel decoder error on the SSB 34 Tuner I2C bus error on the SSB 35 EEPROM I2C error on SSB, M24C64

5.6.4 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.

5.7 The Blinking LED Procedure

5.8.1 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.

5.8.2 Load Default NVM Values

It is possible to upload the default values to the NVM with ComPair in case the SW is changed, the NVM is replaced with a new (empty) one, or when the NVM content is corrupted. After replacing an EEPROM (or with a defective/no EEPROM), default settings should be used to enable the set to start-up and allow the Service Default Mode and Service Alignment Mode to be accessed.

5.8.3 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 back to div. table 6-3

5.8.4 Unstable Picture via HDMI input

Check (via ComPair or factory mode) if HDMI EDID data is properly programmed.

5.7.1 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 SDM, 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.

5.8 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.

5.8.5 No Picture via HDMI input

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

5.8.6 TV Will Not Start-up from Stand-by

Possible Stand-by Controller failure. Re-flash the software.

5.8.7 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.

5.8.8 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.

5.8.9 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!
