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.

Precautions, Notes, and Abbreviation List
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 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. B-TXT C CEC

Service Positions
For easy servicing of this set, there are a few possibilities created: · The buffers from the packaging. · Foam bars (created for Service).
4.1.1
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 Figure 4-1 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 positioning 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, the screen can be monitored.

Service Modes
· 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). Service Default mode (SDM) and Service Alignment Mode (SAM) offer several features for the service technician, while the Customer Service Mode (CSM) is used for communication between the call centre and the customer. This chassis also offers the option of using ComPair, a hardware interface between a computer and the TV chassis. It offers the abilities of structured troubleshooting, error code reading, and software version read-out for all chassis. (see also section 5.3.1 ComPair). · · ·

· 5.2.3 Customer Service Mode (CSM) Purpose When a customer is having problems with his TV-set, he can call his dealer or the Customer Helpdesk. The service technician can then ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severity of the complaint. In many cases, he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer The CSM is a read only mode; therefore, modifications in this mode are not possible When CSM is activated: · A test pattern will be displayed during 3 s. This test pattern is generated by the MT822x video processor. So if this test pattern is shown, it could be determined that the back end video chain (MT822x, LVDS, and display) of the SSB is working. · The LAYER 1 error is displayed via the blinking front LED. Only the latest error is displayed. See also section 5.4 Error Codes. How to Activate CSM Key in the code "123654" via the standard RC transmitter.

Service Tools
ComPair Introduction ComPair (Computer Aided Repair) is a Service tool for Philips Consumer Electronics products. and offers the following: 1. ComPair helps 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. No knowledge on I2C or UART commands is necessary, 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 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). The ComPair fault finding program is able to determine the problem of the defective television, by a combination of automatic diagnostics and an interactive question/answer procedure. How to Connect This is described in the chassis fault finding database in ComPair.

Error Codes
Introduction The error code buffer contains all detected errors since the last time the buffer was erased. The buffer is written from top to bottom (or left to right), new errors are logged at the top/left side, and all other errors shift one position to the bottom/right. When an error occurs, it is added to the list of errors, provided the list is not full. When 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/ There is a simple blinking LED procedure for board level repair (home repair) the so called LAYER 1 errors, next to the existing errors which are LAYER 2 errors: · LAYER 1 errors are one digit errors · LAYER 2 errors are two digit errors. When is LAYER 1 or 2 available: · 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, LAYER 2 is 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. 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). 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.

The Blinking LED Procedure (LAYER-2 codes)
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 that 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 LED pulse with as many pulses as the error code number, followed by a time period of 1.5 seconds in which the LED is "off". Then this sequence is repeated. E.g. 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 this sequence. Displaying the entire error buffer The entire error buffer can be displayed when service mode "SDM" is entered (by remote control command 062596
