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

3.1 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.

5.8 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 Default Mode (SDM).

• Service Alignment Mode (SAM).

• Factory Mode.

• Customer Service Mode (CSM).

• Computer Aided Repair Mode (ComPair).

SDM, SAM and the Factory mode offer features, which can be used by the Service engineer to repair/align a TV set. Some features are:

• A pre-defined situation to ensure measurements can be made under uniform conditions (SDM).

• Activates the blinking LED procedure for error identification when no picture is available (SDM).

• Make alignments (e.g. White Tone), reset the error buffer (SAM and Factory Mode).

• Display information (“SDM” or “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.

C /UART level and can be used by a Service

C with help of

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 SDM and 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 SDM, SAM, and CSM. The screen will show: “AAAAAAB-XXX.YYY.MMM.TTT”, where:

• AAAAAA is the chassis name: TPM1012HE.

• B is the region indication: E = Europe, A = AP/China, U = NAFTA, L = LATAM.

• XXX is the main version number: this is updated with a major change of specification (incompatible with the previous software version). Numbering will go from 0- 255.

• YYY is the sub version number: this is updated with a minor change of specification (incompatible with the previous versions). Numbering will go from 0- 255.

• MMM is the number of the mandatory (upgrade) release in association with the area of the mandatory (upgrade) release. Numbering will go from 0 - 255.

• TTT bit 7 to 1 is the area of the mandatory (upgrade) release where 0 - none, 1 - Netflix, rest reserved.

• TTT bit 0 : 0 = development release, 1 = production release.

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: “062596” 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 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 Default Mode (SDM)

Purpose

Set the TV in SDM mode in order to be able to create a predefined setting for measurements to be made. In this platform, a simplified SDM is introduced (without protection override and without tuning to a predefined frequency).

Specifications

• Set linear video and audio settings to 50%, but volume to 25%. Stored user settings are not affected.

• All service-unfriendly modes (if present) are disabled, since they interfere with diagnosing/repairing a set. These service unfriendly modes are: – (Sleep) timer. – Blue mute/Wall paper. – Auto switch “off” (when there is no “ident” signal). – Hotel or hospital mode. – Child lock or parental lock (manual or via V-chip). – Skipping, blanking of “Not favourite”, “Skipped” or

“Locked” presets/channels.

– Automatic storing of Personal Preset or Last Status

settings.

– Automatic user menu time-out (menu switches

• ERR Shows all errors detected since the last time the buffer was erased in format <xxx> <xxx> <xxx> <xxx> <xxx> (five errors possible).

• OP Used to read-out the option bytes. In this chassis two times eight option codes are used.

How to Navigate

As this mode is read only, there is nothing to navigate. To switch to other modes, use one of the following methods:

• Command MENU from the user remote will exit SDM.

• To prevent the OSD from interfering with measurements in SDM, use the command “Adjust” or “Options” (“STATUS” or “INFO” for NAFTA and LATAM) from the user remote. This will switch the OSD “off” while remaining in the SDM mode. The “SDM” OSD is remains visible in the upper right corner of the screen. To exit SDM switch to “Stand-by” mode.

• Press the following key sequence on the remote control transmitter: “062596” directly followed by the OK button to switch to SAM (do not allow the display to time out between entries while keying the sequence). Remarks: new remote

controls will not have I+ button, but an “INFO” button instead.

How to Exit SDM

• Switch the set to Stand-by, by pressing the standby button on the remote control transmitter or on the television set.

• Via a standard customer RC-transmitter: key in “00”-sequence. Note: If the TV is switched “off” by a power interrupt while in SDM, the TV will show up in the last status of SDM menu as soon as the power is supplied again. The error buffer will not be cleared.

• EDID_clustername.zip: Contains the EDID content of the different EDID NVMs. See ComPair for further instructions.

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/SDM/CSM (if you have a picture).

C device.

C error.

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

Service Modes, Error Codes, and Fault Finding

– 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 5.7 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 missing 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

5.7.1 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.

5.7.2 Displaying the Entire Error Buffer

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.

5.8.1 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 Table 6-3

5.8.4 Unstable Picture via HDMI input

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

5.8.5 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.
