Safety Instructions, Warnings, and Notes

2. Safety Instructions, Warnings, and Notes

EN 5LC7.2HU LB 2.

Index of this chapter:

2.1 Safety Instructions

2.2 Warnings

2.3 Notes

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 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 Mohm and 12 Mohm.

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 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.

2.3 Notes

2.3.1 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 (see chapter 5) with a color 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.

• Manufactured under license from Dolby Laboratories. “Dolby”, “Pro Logic” and the “double-D symbol”, are trademarks of Dolby Laboratories.

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 kohm).

• Resistor values with no multiplier may be indicated with either an “E” or an “R” (e.g. 220E or 220R indicates 220 ohm).

• All capacitor values are given in micro-farads (μ= × 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 in the Spare Parts List. Therefore, always check this list when there is any doubt.

2.3.3 BGA (Ball Grid Array) ICs

Introduction

For more information on how to handle BGA devices, visit this URL: www.atyourservice.ce.philips.com (needs subscription, not available for all regions). After login, select “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, which is coupled to the 12NC. For an overview of these profiles, visit the website www.atyourservice.ce.philips.com (needs subscription, but is not available for all regions) You will find this and more technical information within the “Magazine”, chapter “Repair downloads”. For additional questions please contact your local repair help desk.

2.3.4 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 Philips SAC305 with order code 0622 149 00106. 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

-9

), or pico-farads (p= × 10

-12

-6

EN 6 LC7.2HU LB3.

avoid mixed regimes. If this cannot be avoided, carefully

clear the solder-joint from old tin and re-solder with new tin.

2.3.5 Alternative BOM identification

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.

Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 1 and 2 refer to the production center (e.g. AG is Bruges), 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 2006 week 17). The 6 last digits contain the serial number.

2.3.6 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!

2.3.7 Practical Service Precautions

• It makes sense to avoid exposure to electrical shock.

• Always respect voltages. While some may not be

Figure 2-1 Serial number (example)

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.

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.

The foam bars (order code 3122 785 90580 for two pieces) can be used for all types and sizes of Flat TVs. See figure “Foam bars” for details. Sets with a display of 42” and larger, require four foam bars [1]. Ensure that the foam bars are always supporting the cabinet and never only the display. Caution: Failure to follow these guidelines can seriously damage the display! By laying the TV face down on the (ESD protective) foam bars, a stable situation is created to perform measurements and alignments. By placing a mirror under the TV, you can monitor the screen.

5.8 Fault Finding and Repair Tips

5.1 Test Points

In the chassis schematics and layout overviews, the test points (Fxxx) are mentioned. In the schematics, test points are indicated with a rectangular box around “Fxxx” or “Ixxx”, in the layout overviews with a “half-moon” sign. As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. 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: Color bar signal.

• Audio: 3 kHz left, 1 kHz right.

5.2 Hotel Mode

Before the service modes can be activated, the set needs to be switched into normal consumer mode (MTV-Mode) first. Use an iTV setup remote control (type: RC2753/01, 12nc: 3139 228

88782) to key in the code ‘024995’ directly followed by the MENU button. The text messages “TV Is Now In MTV Mode” and “Please Do A Cold Start!” appears on the screen. Disconnect the set for a few seconds from the mains supply, reconnect the set to the mains supply again. The set is now in the normal consumer mode (MTV-Mode).

After repair, place the set into hotel mode (iTV-Mode) again. Key-in the same code on the remote control as described above. The text message “TV Is Now In ITV Mode” appears. A cold start must be performed as described above. The set is now in the hotel mode (iTV-Mode) again.

5.3 Service Modes

Important: Only when the set is in normal consumer mode

(MTV Mode), all service modes can be accessed.

The Service Mode feature is split into four parts:

• Service Default Mode (SDM).

• Service Alignment Mode (SAM).

• Customer Service Mode (CSM).

• Computer Aided Repair Mode (ComPair).

SDM and SAM 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).

• The possibility to overrule software protections when SDM was entered via the Service pins.

• Make alignments (e.g. white tone), (de)select options, enter options codes, reset the error buffer (SAM).

• Display information (“SDM” or “SAM” indication in upper right corner of screen, error buffer, software version, operating hours, options and option codes, sub menus).

• Fixed audio and video settings.

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 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 I2C /UART level and can be used by a Service engineer to quickly diagnose the TV set by reading out error codes, read and write in NVMs, communicate with ICs and the uP (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 I2C with help of 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).

5.3.1 General

Some items are applicable to all Service Modes or are general. These are listed below.

Life Timer

During the life time cycle of the TV set, a timer is kept. It counts the normal operation hours (not the Stand-by hours). The actual value of the timer is displayed in SDM and CSM in a decimal value. Every two soft-resets increase the hour by +1.

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: “AAAABCD X.YY”, where:

• AAAA is the chassis name: LC71 for analogue range (nonDVB/ATSC), LC72 for digital range (DVB/ATSC).

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

• C is the display indication: L= LCD, P= Plasma.

• D is the language/feature indication: 1= standard, H= 1080p full HD.

• 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 - 9 and A - Z. – 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.

• YY is the sub version number: this is updated with a minor change (backwards compatible with the previous versions) Numbering will go from 00 - 99. – If the sub version number changes, the new version

number is written in the NVM.

– If the NVM is fresh, the software identification, version,

and cluster will 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 “xxx”, where “xxx” is a 3 digit decimal value of the panel type: see column “Panel Code” in table “Option and display code overview” (chapter 8), or see sticker on the side/bottom of the cabinet. When the value is accepted and stored in NVM, the set

followed by MENU and

During this algorithm, the NVM-content must be filtered, because several items in the NVM are TV-related and not SSBrelated (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, he needs to look to the side/bottom sticker to identify the set, for further actions.

5.3.2 Service Default Mode (SDM)

Purpose

Set the TV in SDM mode in order to be able to:

• Create a pre-defined setting for measurements to be made.

• Override software protections.

• Start the blinking LED procedure.

• Read the error buffer.

• Check the life timer.

Specifications

• Short one of the “Service” jumpers on the TV board during cold start (see Figures “Service jumper”). Then press the mains button (remove the short after start-up). Caution: Activating SDM by shorting “Service” jumpers will override the DC speaker protection (error 1), the General I2C error (error 4), and the Trident video processor error (error 5). When doing this, the service-technician must know exactly what he is doing, as it could damage the television set.

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 you 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. You do not have to know anything about I yourself, because ComPair takes care of this.

3. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the uP is working) and all repair information is directly available.

4. ComPair features TV software upgrade possibilities.

Specifications

ComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The (new) 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).

How to Connect

This is described in the ComPair chassis fault finding database.

Support of the LVDS Tool has been discontinued.

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 protection.

• Failing I2C device.

• General I2C error.

• SDRAM failure.

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 may never lead to a deadlock situation. This means that it must always be diagnosable (e.g. error buffer via OSD or blinking LED procedure, ComPair to read from the NVM). 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.

Example: In case of a failure of the I2C bus (CAUSE), the error code for a “General I2C failure” and “Protection errors” is displayed. The error codes for the single devices (EFFECT) is not displayed. All error codes are stored in the same error buffer (TV’s NVM) except when the NVM itself is defective.

5.5.2 How to Read the Error Buffer

You can read the error buffer in 3 ways:

• On screen via the SAM/SDM/CSM (if you have a picture). Example: – ERROR: 0 0 0 0 0: No errors detected – ERROR: 6 0 0 0 0: Error code 6 is the last and only

detected error

– ERROR: 9 6 0 0 0: Error code 6 was detected first and

error code 9 is the last detected (newest) error

• Via the blinking LED procedure (when you have no picture). See “The Blinking LED Procedure”.

•Via ComPair.

5.5.3 Error Codes

In case of non-intermittent faults, write down the errors present in the error buffer and clear the error buffer before you begin the repair. This ensures that old error codes are no longer present. If possible, check the entire contents of the error buffer. In some situations, an error code is only the result of another error

and not the actual cause of the problem (for example, a fault in the protection detection circuitry can also lead to a protection).

Notes

1. Some of the error codes reported are depending on the option code configurations.

2. This error means: no I2C device is responding to the particular I2C bus. Possible causes: SCL/SDA shorted to GND, SCL shorted to SDA, or SCL/SDA open (at uP pin). The internal bus of the Trident platform should not cause the entire system to halt as such an error can be reported.

3. The following error codes which must be trigger the blinking LED automatically once detected, due to the fact these error may cause no display on the screen: Errors 1, 2, 3, 4, 5, 6 and 10.

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: – To enter SAM, press the following key sequence on the

remote control transmitter: “062596” directly followed by the OSD/i+ button (do not allow the display to time out between entries while keying the sequence).

– Make sure the menu item CLEAR is selected. Use the

MENU UP/DOWN buttons, if necessary.

– Press the MENU RIGHT button to clear the error

buffer. The text on the right side of the “CLEAR” line will change from “CLEAR?” to “CLEARED”

• If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically.

Service Modes, Error Codes, and Fault Finding

EN 17LC7.2HU LB 5.

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.

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 RC5 command terminates the sequence. Error code LED blinking is in red color.

Example (2): the content of the error buffer is “129600” 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.

5.6.2 Displaying the Entire Error Buffer

Additionally, the entire error buffer is displayed when Service Mode “SDM” is entered. In case the TV set is in protection or Stand-by: The blinking LED procedure sequence (as in SDMmode in normal operation) must be triggered by the following RC sequence: “MUTE” “062500” “OK”. In order to avoid confusion with RC5 signal reception blinking, this blinking procedure is terminated when a RC5 command is received.

To erase the error buffer, the RC command “MUTE” “062599

“OK” can be used.

5.7 Software Upgrading

In this chassis, two SW “stacks” are used:

• TV main SW (processor and processor NVM).

•Digital TV SW.

5.7.1 TV Main SW Upgrade

For instructions on how to upgrade the TV Main software, refer to ComPair.

5.7.2 “Digital TV” Software Upgrade

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 the NVM settings 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.

Table 5-3 NVM editor overview

.ADR 0x000A 10 Existing value

.VAL 0x0000 0 New value

.Store Store?

5.8.2 Load Default NVM Values

It is possible to download default values automatically into the NVM in case a blank NVM is placed or when the NVM first 20 address contents are “FF”. After the default values are downloaded, it is possible to start-up and to start aligning the TV set. To initiate a forced default download the following action has to be performed:

1. Switch “off” the TV set with the mains cord disconnected from the wall outlet (it does not matter if this is from “Standby” or “Off” situation).

2. Short-circuit the SDM jumpers on the SSB (keep short circuited).

3. Press “P+” or “CH+” on the local keyboard (and keep it pressed).

4. Reconnect the mains supply to the wall outlet.

5. Release the “P+” or “CH+” when the set is “on” or blue LED is blinking.

When the downloading has completed successfully, the set should be into Stand-by, i.e. red LED on.

Alternative method (1):

1. Go to SAM.

2. Select NVM Editor.

3. Select ADR (address) to 1 (dec).

4. Change the VAL (value) to 170 (dec).

5. Store the value.

6. Do a hard reset to make sure new default values took place.

Alternative method (2):

It is also 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.

This is done automatically via OAD (Over the Air Download).

• 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.

5.8.3 Start-up/Shut-down Flowcharts

Important note for DVB/ATSC sets:

• When you put a DVB/ATSC set into Stand-by mode with an RC, the set will go to “Semi Stand-by” mode for 5 minutes. This, to facilitate “Over the Air download” (OAD). If there is no activity within these 5 minutes, the set will switch to Stand-by mode. In “Semi Stand-by” mode, the LCD backlight and Audio Amplifier are turned “off” but other circuits still work as normal. The customer might think the set is in Stand-by. However, in real Stand-by mode, only

Service Modes, Error Codes, and Fault Finding

the uP and the NVM are alive and all other circuits are switched “off”.

• If you press the mains switch at the local key board in a DVB/ATSC set, the set will switch to Stand-by mode.

2. Check Panel port.

- If Panel Pin = LOW and check slave address 0x65 = 0xA5, Enter Panel Mode.

On the next pages you will find start-up and shut-down flowcharts, which might be helpful during fault finding. Please note that some events are only related to PDP sets, and therefore not applicable to this LCD chassis.
