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.
3.1
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. Of de set ontploft! 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. 3.3.2
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 on the Philips Spare Parts Web Portal.

BGA (Ball Grid Array) ICs Introduction For more information on how to handle BGA devices, visit this URL: http://www.atyourservice-magazine.com. 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. Where applicable and available, this profile is added to the IC Data Sheet information section in this manual.
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.
3.3.5
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.

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 centre (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 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.

Test Points
In the chassis schematics and layout overviews, the test points are mentioned. In the schematics, test points are indicated with "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
Service Modes
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 is 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). 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 ComPair connector, which will be accessible through the rear of the set (without removing the rear cover).
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 favorite", "Skipped" or "Locked" presets/channels. Automatic storing of Personal Preset or Last Status settings. Automatic user menu time-out (menu switches back/ OFF automatically. Auto Volume levelling (AVL).
How to Activate SDM For this chassis there are two kinds of SDM: an analog SDM and a digital SDM. Tuning will happen according Table 5-1. · Analog SDM: use the standard RC-transmitter and key in the code "062596", directly followed by the "MENU" (or HOME) button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the "MENU" (or HOME) button again. · Digital SDM: use the standard RC-transmitter and key in the code "062593", directly followed by the "MENU" (or HOME) button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the "MENU" (or HOME) button again. · Analog SDM can also be activated by grounding for a moment the solder pad on the SSB, with the indication "SDM" (see figure Service mode pad).

Note that if the option code numbers are changed, these have to be confirmed with pressing the "OK" button before the options are stored. Otherwise changes will be lost. Initialize NVM. The moment the processor recognizes a corrupted NVM, the "initialize NVM" line will be highlighted. Now, two things can be done (dependent of the service instructions at that moment): Save the content of the NVM via ComPair for development analysis, before initializing. This will give the Service department an extra possibility for diagnosis (e.g. when Development asks for this). Initialize the NVM.

Figure 5-1 Service mode pad After activating this mode, "SDM" will appear in the upper right corner of the screen (when a picture is available). How to Navigate When the "MENU" (or HOME) button is pressed on the RC transmitter, the TV set will toggle between the SDM and the normal user menu. How to Exit SDM Use one of the following methods: · Switch the set to STAND-BY via the RC-transmitter. · Via a standard customer RC-transmitter: key in "00"sequence. 5.2.2 Service Alignment Mode (SAM) Purpose · To perform (software) alignments. · To change option settings. · To easily identify the used software version. · To view operation hours. · To display (or clear) the error code buffer. How to Activate SAM Via a standard RC transmitter: Key in the code "062596" directly followed by the "INFO" button. After activating SAM with this method a service warning will appear on the screen, continue by pressing the "OK" button on the RC. Contents of SAM (see also Table 6-6) · Hardware Info. A. SW Version. Displays the software version of the main software (example: LC93L-1.2.3.4= AAAAB_X.Y.W.Z). · AAAA= the chassis name. · B= the region (A= Asian Pacific, E= Europe, L= Latam, U= United States). · X.Y.W.Z= the software version, where X is the main version number (different numbers are not compatible with one another) and Y.W.Z is the sub version number (a higher number is always compatible with a lower number). B. Standby Processor Version. Displays the software version of the Stand-by processor. C. Production Code. Displays the production code of the TV, this is the serial number as printed on the back of the TV set. Note that if an NVM is replaced or is initialized after corruption, this production code has to be re-written to NVM. ComPair will foresee in a possibility to do this.
Note: When the NVM is corrupted, or replaced, there is a high possibility that no picture appears because the display code is not correct. So, before initializing the NVM via the SAM, a picture is necessary and therefore the correct display option has to be entered. To adapt this option bit, it is advised to use ComPair (the correct values for the options can be found in Table 6-5) or a method via a standard RC (described below). Changing the display option via a standard RC: Key in the code "062598" directly followed by the "MENU" (or HOME) button and "XXX" (where XXX is the 3 digit decimal display code as mentioned in Table 6-5). Make sure to key in all three digits, also the leading zero's. If the above action is successful, the front LED will go out as an indication that the RC sequence was correct. After the display option is changed in the NVM, the TV will go to the Stand-by mode. If the NVM was corrupted or empty before this action, it will be initialized first (loaded with default values). This initializing can take up to 20 seconds.

To upload the settings select each item separately, press "cursor right" (or the "OK" button), confirm with "OK" and wait until "Done" appears. In case the download to the USB stick was not successful "Failure" will appear. In this case, check if the USB stick is connected properly and if the directory "repair" is present in the root of the USB stick. Now the settings are stored onto the USB stick and can be used to download onto another TV or other SSB. Uploading is of course only possible if the software is running and if a picture is available. This method is created to be able to save the customer's TV settings and to store them into another SSB. Download to USB. To download several settings from the USB stick to the TV, same way of working needs to be followed as with uploading. To make sure that the download of the channel list from USB to the TV is executed properly, it is necessary to restart the TV and tune to a valid preset if necessary. Note: The "History list item" can not be downloaded from USB to the TV. This is a "read-only" item. In case of specific problems, the development department can ask for this info. ·

Service Tools
ComPair Introduction ComPair (Computer Aided Repair) is a Service tool for Philips Consumer Lifestyle 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. 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.

Error Codes
Introduction The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from left to right, new errors are logged at the left side, and all other errors shift one position to the right. When an error occurs, it is added to the list of errors, provided the list is not full. When an error occurs and the error buffer is full, then the new error is not added, and the error buffer stays intact (history is maintained). To prevent that an occasional error stays in the list forever, the error is removed from the list after more than 50 hrs. of operation. When multiple errors occur (errors occurred within a short time span), there is a high probability that there is some relation between them. New in this chassis is the way errors are displayed: · There is a simple blinking LED procedure for board level repair (home repair) so called LAYER 1 errors, next to the existing errors which are LAYER 2 errors (see Table 5-3). LAYER 1 errors are one digit errors (via CSM). LAYER 2 errors are 2 digit errors (via SAM/SDM). · In protection mode: From consumer mode: LAYER 1. From SDM mode: LAYER 2. · In CSM mode: When entering CSM: error LAYER 1 will be displayed by blinking LED. Only the latest error is shown. · In SDM mode: When SDM is entered via Remote Control code or the hardware pins, LAYER 2 is displayed via blinking LED. · In the "ON" state: with the RC commands "mute_06250X _OK", LAYER 2 errors are displayed via blinking LED. · Error display on screen: In CSM no error codes are displayed on screen. In SAM the complete error list is shown.

5.4.4 Error Buffer In case of non-intermittent faults, clear the error buffer before starting to repair (before clearing the buffer, write down the content, as this history can give significant information). This to ensure 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 code and not the actual cause (e.g. a fault in the protection detection circuitry can also lead to a protection). Take notice that some errors need several minutes before they start blinking or before they will be logged. So in case of problems wait 2 minutes from start-up onwards, and then check if the front LED is blinking or if an error is logged. Table 5-3 Error code overview

The Blinking LED Procedure
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 "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. In order to avoid confusion with RC5 signal reception blinking, this blinking procedure is terminated when a RC5 command is received.
5.5.2
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".

Service Modes, Error Codes, and Fault Finding
5. Stop bits = 1 6. Flow control = none During the start-up of the TV set, the logging will be displayed. This is also the case during rebooting of the TV set (the same logging appears time after time). Also available in the logging is the "Display Option Code" (useful when there is no picture), look for item "DisplayRawNumber" in the beginning of the logging. Tip: when there is no picture available during rebooting you are able to check for "error devices" in the logging (LAYER 2 error) which can be very helpful to determine the failure cause of the reboot. For protection state, there is no logging. 5.6.4 Display option code Caution: In case you have replaced the SSB, always check the display option code in SAM, even if you have picture. With a wrong display option code it is possible that you have picture, but that in certain conditions you have unwanted side-effects. 5.6.5 Trouble Shooting Tuner section When there is no picture in analog RF mode: 1. Check whether picture is present in AV mode. If not, tuner section is okay. Check video processing section. 2. Check if option settings are correct. 3. Check if 5 and 33 V supplies are available. 4. Check if the I2C lines are working correctly (3.3 V). 5. Manually store a known channel and check if there is IF output at tuner pin 11. If not, tuner is faulty. 6. Feed in 105 dBuV at tuner pin 11 and check whether there is CVBS output from IF demodulator IC. If not, IF demodulator might be faulty. Check components in this area.
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.
5.6.1
Software Protections Most of the protections and errors use either the stand-by or the micro processor as detection device. Since in these cases, checking of observers, polling of ADCs, and filtering of input values are all heavily software based, these protections are referred to as software protections. There are several types of software related protections, solving a variety of fault conditions: · Protections related to supplies: check of the 12V. · Protections related to breakdown of the safety check mechanism. E.g. since the protection detections are done by means of software, failing of the software will have to initiate a protection mode since safety cannot be guaranteed any more. Remark on the Supply Errors The detection of a supply dip or supply loss during the normal playing of the set does not lead to a protection, but to a cold reboot of the set. If the supply is still missing after the reboot, the TV will go to protection. Protections during Start-up During TV start-up, some voltages and IC observers are actively monitored to be able to optimize the start-up speed, and to assure good operation of all components. If these monitors do not respond in a defined way, this indicates a malfunction of the system and leads to a protection.

Software Upgrading
Introduction It is possible for the user to upgrade the main software via the USB port. This allows replacement of a software image in a stand alone set, without the need of an E-JTAG debugger. A description on how to upgrade the main software can be found in the DFU. Important: When the NAND-Flash must be replaced, a new SSB must be ordered, due to the presence of the security keys! (copy protection keys, MAC address, ...). Perform the following actions after SSB replacement: 1. Set the correct option codes (see sticker inside the TV). 2. Update the TV software => see the DFU for instructions. 3. Perform the alignments as described in chapter 6. 4. Check in CSM if the HDMI key, MAC address.. are valid. For the correct order number of a new SSB, always refer to the Spare Parts list on the Philips Service web portal!
5.6.2
Hardware Protections The only real hardware protection in this chassis is (in case of an audio problem) the audio protection circuit that will trigger the uP to switch "off" the TV. Repair Tip · It is also possible that you have an audio DC protection because of an interruption in one or both speakers (the DC voltage that is still on the circuit cannot disappear through the speakers). Caution: (dis)connecting the speaker wires during the ON state of the TV at high volume can damage the audio amplifier.
5.6.3
Logging When something is wrong with the TV set (f.i.the set is rebooting) you can check for more information via the logging in Hyperterminal. The Hyperterminal is available in every Windows application via Programs, Accessories, Communications, Hyperterminal. Connect a "ComPair UART"cable (3138 188 75051) from the service connector in the TV to the "multi function" jack at the front of ComPair II box. Required settings in ComPair before starting to log: - Start up the ComPair application. - Select the correct database (open file "Q549.3E LA", this will set the ComPair interface in the appropriate mode). - Close ComPair After start-up of the Hyperterminal, fill in a name (f.i. "logging") in the "Connection Description" box, then apply the following settings: 1. COMx 2. Bits per second = 115200 3. Data bits = 8 4. Parity = none

Software Upgrade SW versions can be divided in three types: · SW that can not crash the working of the set. EDID NVM. If the download fails, the set is still running and the download can start again. Main NVM: If the download fails the default NVM value can be loaded. NVM can be loaded via USB, be aware PCBA alignments stored in NVM will not be overridden. · SW that is "fool proof": There is a backup version, a main interruption during upgrade shall not crash the normal working, a new upgrade can be started. Main SW image: Upgradable via USB. Standby SW. ARM Ambilight (if applicable): Upgradable via USB. · SW that is not "fool proof".
