Safety Instructions, Warnings, and Notes EN 5LC8.1E LB 2.
2. Safety Instructions, Warnings, and Notes Index of this chapter:2.1 Safety Instructions2.2 Warnings2.3 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 ,
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.
2.2 Warnings
All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD ). 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 (), or hot ground (), 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 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 () and without () aerial signal. Measure the voltages in the power supply section both in normal operation () and in stand-by (). These values are indicated by means of the appropriate symbols.
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 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 ( = 10-6), nano-farads (n = 10-9), or pico-farads (p = 10-12).
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
IntroductionFor 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 ProfilesFor 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 400C. 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 360C - 380C is reached and stabilized at the solder joint. Heating time of the solder-joint should not exceed ~ 4 sec. Avoid temperatures above 400C, 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.

Directions for UseEN 6 LC8.1E LB3.
2.3.5 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.
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.
Figure 2-1 Serial number (example)
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. 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.

For easy servicing of this set, there are a few possibilities created: The buffers from the packaging (see figure Rear cover). Foam bars (created for Service).
4.2.1 Foam Bars
Figure 4-3 Foam bars
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.

Service Modes, Error Codes, and Fault FindingEN 12 LC8.1E LB5.
5. Service Modes, Error Codes, and Fault FindingIndex of this chapter:5.1 Test Points5.2 Service Modes5.3 Service Tools5.4 Error Codes5.5 The Blinking LED Procedure5.6 Software Upgrading5.7 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.
5.2 Service Modes
The Service Mode feature is split into four parts: Simplified 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: Activates the blinking LED procedure for error identification
when no picture is available (SDM). Make alignments (e.g. white tone), (de)select options,
enter options codes, reset the error buffer (SAM). Display information (SAM indication in upper right corner
of screen, error buffer, software version, 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 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 compare connector, which will be accessible through the rear of the set (without removing the rear cover).
5.2.1 General
Some items are applicable to all Service Modes or are general.These are listed below.
Software Identification, Version, and ClusterThe 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: LC81.
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 SelectionWhen 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 the OSD Panel Selection will displayed on screen and xxx, where xxx is a 3 digit decimal value of the panel type: see column Display code in table Option code overview (ch. 8), or see sticker on the side/bottom of the cabinet. When the valueis accepted and stored in NVM, the OSD Panel Selection will be disappear set remain on, to indicate that the process has been completed.
Figure 5-1 Location of Display Option Code sticker
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, he needs to look to the side/bottom sticker to identify the set, for further actions.
5.2.2 Service Default Mode (SDM)
PurposeThis simplified SDM mode in LC8.1E LB chassis is used for Error blinking only. Start the blinking LED procedure.
How to Activate Press the following key sequence on the remote control

5.2.4 Customer Service Mode (CSM)
PurposeThe Customer Service Mode shows error codes and information on the TVs operation settings. A call centre can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps them to diagnose problems and failures in the TV before making a service call. The CSM is a read-only mode; therefore, modifications are not possible in this mode.
Specifications Ignore Service unfriendly modes. Line number for every line (to make CSM language
independent). Set the screen mode to full screen (all contents on screen
are viewable). After leaving the Customer Service Mode, the original
settings are restored. Possibility to use CH+ or CH- for channel surfing, or
enter the specific channel number on the RC.

5.3 Service Tools
5.3.1 ComPair
IntroductionComPair (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 I2C or UART commands 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 up possibilities.
SpecificationsComPair 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 ConnectThis is described in the ComPair chassis fault finding database.
Figure 5-5 ComPair II interface connection
Caution: It is compulsory to connect the TV to the PC as shown in the picture above (with the ComPair interface inbetween), as the ComPair interface acts as a level shifter. If one connects the TV directly to the PC (via UART), ICs will be blown!

5.3.2 LVDS Tool
Support of the LVDS Tool has been discontinued.
5.4 Error Codes
5.4.1 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.The last errors, stored in the NVM, are shown in the Service menus. 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 code for the single devices (EFFECT) is not displayed. All error codes are stored in the same error buffer (TVs NVM) except when the NVM itself is defective.
5.4.2 How to Read the Error Buffer
You can read the error buffer in 2 ways: On screen via the SAM/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.
5.4.3 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 errorand not the actual cause of the problem (for example, a fault in the protection detection circuitry can also lead to a protection).
-
Service Modes, Error Codes, and Fault FindingEN 16 LC8.1E LB5.
Table 5-1 Error code overview
Notes1. 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 NXP (Loctop) platform should not cause the entire system to halt as such an error can be reported.
5.4.4 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/STATUS/INFO/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. Press the right button twice (1st is to select the text Yes on the right side menu and the 2nd press is to clear the error buffer in NVM the text CLEARED will appear).
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.
5.5 The Blinking LED Procedure
5.5.1 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 / White colour (refer to Error codes overview).
Example (2): the content of the error buffer is 1 2 9 6 0 0After entering SDM, the following occurs: 1 long blinks 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 blinks of 1.5 seconds to finish the sequence, The sequence starts again with 12 short blinks.
5.6 Software Upgrading
In this chassis, the following SW stacks is used: TV main SW (processor and processor NVM).
5.6.1 TV Main SW Upgrade
For instructions on how to upgrade the TV Main software, refer to ComPair.
5.6.2 Service SSB
It should be noted that in this chassis the HDCP-key is embedded in the main processor. Therefore there is no need for a separate Service-SSB.

5.7 Fault Finding and Repair Tips
Notes: 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 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 theTV set. Alternative method: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.
5.7.2 Start-up/Shut-down Flowcharts
On the next pages you will find start-up and shut-down flowcharts, followed by a trouble shooting flowchart, whichmight be helpful during fault finding.Please note that some events are only related to PDP sets, and therefore not applicable to this LCD chassis.
