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.

5.1 Service Modes

The Service Mode feature is split into five parts:

• Service Alignment Mode (SAM).

• Factory Mode.

• Customer Service Mode (CSM).

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:

• 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.

• 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.

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: “AAAAAB-XXX.YYY.MMM.TTT”, where:

• AAAAA is the chassis name: QM164.

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

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.
