2. Safety Instructions, Warnings, and Notes
Index of this chapter: 2.1 Safety Instructions 2.2 Warnings 2.3 Notes · 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. The semiconductors indicated in the circuit diagram and in the parts lists, are interchangeable per position with the semiconductors in the unit, irrespective of the type indication on these semiconductors. Manufactured under license from Dolby Laboratories. "Dolby", "Pro Logic" and the "double-D symbol", are trademarks of Dolby Laboratories.
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.
·

2.3.2
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= x10-6), nano-farads (n= x10-9), or pico-farads (p= x10-12). 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
Rework on BGA (Ball Grid Array) ICs General Although (LF)BGA assembly yields are very high, there may still be a requirement for component rework. By rework, we mean the process of removing the component from the PWB and replacing it with a new component. If an (LF)BGA is removed from a PWB, the solder balls of the component are deformed drastically so the removed (LF)BGA has to be discarded. Device Removal As is the case with any component that, is being removed, it is essential when removing an (LF)BGA, that the board, tracks, solder lands, or surrounding components are not damaged. To remove an (LF)BGA, the board must be uniformly heated to a temperature close to the reflow soldering temperature. A uniform temperature reduces the risk of warping the PWB. To do this, we recommend that the board is heated until it is certain that all the joints are molten. Then carefully pull the component off the board with a vacuum nozzle. For the appropriate temperature profiles, see the IC data sheet. Area Preparation When the component has been removed, the vacant IC area must be cleaned before replacing the (LF)BGA. Removing an IC often leaves varying amounts of solder on the mounting lands. This excessive solder can be removed with either a solder sucker or solder wick. The remaining flux can be removed with a brush and cleaning agent. After the board is properly cleaned and inspected, apply flux on the solder lands and on the connection balls of the (LF)BGA. Note: Do not apply solder paste, as this has been shown to result in problems during re-soldering.
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. Available ESD protection equipment: Complete kit ESD3 (small tablemat, wristband, connection box, extension cable and earth cable) 4822 310 10671. Wristband tester 4822 344 13999. 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.

Safety Instructions, Warnings, and Notes
avoid mixed regimes. If this cannot be avoided, carefully clear the solder-joint from old tin and re-solder with new tin. Use only original spare-parts listed in the Service-Manuals. Not listed standard material (commodities) has to be purchased at external companies. Special information for lead-free BGA ICs: these ICs will be delivered in so-called "dry-packaging" to protect the IC against moisture. This packaging may only be opened shortly before it is used (soldered). Otherwise the body of the IC gets "wet" inside and during the heating time the structure of the IC will be destroyed due to high (steam-) pressure inside the body. If the packaging was opened before usage, the IC has to be heated up for some hours (around 90°C) for drying (think of ESD-protection!). Do not re-use BGAs at all! For sets produced before 1.1.2005, containing leaded soldering tin and components, all needed spare parts will be available till the end of the service period. For the repair of such sets nothing changes.
Device Replacement The last step in the repair process is to solder the new component on the board. Ideally, the (LF)BGA should be aligned under a microscope or magnifying glass. If this is not possible, try to align the (LF)BGA with any board markers. So as not to damage neighbouring components, it may be necessary to reduce some temperatures and times. More Information 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. 2.3.4 Lead-free Solder Philips CE is producing lead-free sets (PBF) from 1.1.2005 onwards. Identification: The bottom line of a type plate gives a 14-digit serial number. Digits 5 and 6 refer to the production year, digits 7 and 8 refer to production week (in example below it is 1991 week 18).
·
·
·
In case of doubt whether the board is lead-free or not (or with mixed technologies), you can use the following method: · Always use the highest temperature to solder, when using SAC305 (see also instructions below). · De-solder thoroughly (clean solder joints to avoid mix of two alloys). Caution: For BGA-ICs, you must use the correct temperatureprofile, 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. 2.3.5 Alternative BOM identification In September 2003, Philips CE introduced a change in the way the serial number (or production number, see Figure 2-1) is composed. From this date on, the third digit in the serial number (example: AG2B0335000001) indicates the number of the alternative BOM (Bill of Materials used for producing the specific model of TV set). 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 O.E.M.s. By looking at the third digit of the serial number, the service technician can see if there is more than one type of B.O.M. used in the production of the TV set he is working with. He can then consult the At Your Service Web site, where he can type in the Commercial Type Version Number of the TV set (e.g. 28PW9515/12), after which a screen will appear that gives information about the number of alternative B.O.M.s used. If the third digit of the serial number contains the number 1 (example: AG1B033500001), then there is only one B.O.M. version of the TV set on the market. If the third digit is a 2 (example: AG2B0335000001), then there are two different B.O.M.s. Information about 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. 2.3.6 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.

Figure 2-2 Lead-free logo 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

5.1
Test Points
As most signals are digital, it will be almost impossible to measure waveforms with a standard oscilloscope. Therefore, waveforms are not given in this manual. 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
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 a Customer Helpdesk and a customer. There is also the option of using ComPair, a hardware interface between a computer (see requirements below) and the TV chassis. It offers the ability of structured troubleshooting, test pattern generation, error code reading, software version readout, and software upgrading.
How to Activate SDM Use one of the following methods: · Use the standard RC-transmitter and key in the code "062596", directly followed by the "MENU" button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "off", push the "MENU" button again. · Short for a moment the two solder pads [1] on the SSB, with the indication "SDM". They are located outside the shielding. Activation can be performed in all modes, except when the set has a problem with the Stand-by Processor. See figure "SDM service pads".

Minimum requirements for ComPair: a Pentium processor, Windows 95/98, and a CD-ROM drive (see also paragraph "ComPair"). 5.2.1 Service Default Mode (SDM) Purpose · To create a pre-defined setting, to get the same measurement results as given in this manual. · To override SW protections (only applicable for protections detected by stand-by processor) and make the TV start up to the step just before protection (a sort of automatic stepwise start up). See paragraph "Stepwise Start Up". · To start the blinking LED procedure (not valid in protection mode). Specifications Table 5-1 SDM default settings Default system PAL B/G NTSC M

Figure 5-1 SDM service pads After activating this mode, "SDM" will appear in the upper right corner of the screen (if you have picture). How to Navigate When you press the "MENU" button on the RC transmitter, the set will toggle between the SDM and the normal user menu (with the SDM mode still active in the background). 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.

Service Modes, Error Codes, and Fault Finding
Note: When you have a corrupted NVM, or you have replaced the NVM, there is a high possibility that you will not have picture any more because your display option is not correct. So, before you can initialize your NVM via the SAM, you need to have a picture and therefore you need the correct display option. To adapt this option, use ComPair. The correct HEX values for the options can be found in the table below.The display option code (decimal) is also available on the option code sticker located inside the TV mentioned by "Screen Diversity" e.g. 044. Remark: use always 3 digits for the display option code, for "7" => "007".
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, you can continue by pressing the red button on the RC. Contents of SAM: · Hardware Info. A. VIPER SW Version. Displays the software version of the VIPER software (main software) (example: BJ24U-1.2.3.4_12345 = AAAAB_X.Y.W.Z_NNNNN). · AAAA= the chassis name. · B= the region: A= AP, E= EU, L= Latam, U = US. · X.Y.W.Z= the software version, where X is the main version number (different numbers are not compatible with one another) and Y is the sub version number (a higher number is always compatible with a lower number). The last two digits are used for development reasons only, so they will always be zero in official releases. · NNNNN= last five digits of 12nc code of the software. B. SBY PROC 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. · Operation Hours. Displays the accumulated total of operation hours (not the stand-by hours). Every time the TV is switched "on/off", 0.5 hours is added to this number. · Errors. (Followed by maximal 10 errors). The most recent error is displayed at the upper left (for an error explanation see paragraph "Error Codes"). · Defective Module. Here the module that generates the error is displayed. If there are multiple errors in the buffer, which are not all generated by a single module, there is probably another defect.Take into account that not all errors will create a defective module message. · Reset Error Buffer. When you press "cursor right" and then the "OK" button, the error buffer is reset. · Alignments. This will activate the "ALIGNMENTS" submenu. · Dealer Options. Extra features for the dealers. · Options. Extra features for Service. · Initialize NVM. When an NVM was corrupted (or replaced) in the former EMG based chassis, the microprocessor replaces the content with default data (to assure that the set can operate). However, all preferences and alignment values are gone now, and option numbers are not correct. Therefore, this was a very drastic way. In this chassis, the procedure is implemented in another way: The moment the processor recognizes a corrupted NVM, the "initialize NVM" line will be highlighted. Now, you can do two things (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 (same as in the past, however now it happens conscious).

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. How to Activate CSM Key in the code "123654" via the standard RC transmitter. Note: Activation of the CSM is only possible if there is no (user) menu on the screen! How to Navigate By means of the "CURSOR-DOWN/UP" knob on the RCtransmitter, you can navigate through the menus. Contents of CSM · SW Version (example: BJ24U-1.2.3.4_12345). Displays the built-in main software version. In case of field problems related to software, software can be upgraded. As this software is consumer upgradeable, it will also be published on the Internet. · SBY Processor Version. Displays the built-in stand-by processor software version. Upgrading this software will be possible via a PC and a ComPair interface (see chapter Software upgrade). · Set Type. This information is very helpful for a helpdesk/ workshop as reference for further diagnosis. In this way, it is not necessary for the customer to look at the rear of the TV.In case you have no picture, the set type and the serial number are also located at the bottom of the front from the TV.There you should find a sticker with the mentioned data on it.Note that if an NVM is replaced or is initialized after corruption, this set type has to be re-written to NVM. ComPair will foresee a possibility to do this. · Production Code. Displays the production code (the serial number) of the TV. 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 a possibility to do this. · Code 1. Gives the latest five errors of the error buffer. As soon as the built-in diagnose software has detected an error the buffer is adapted. The last occurred error is displayed on the leftmost position. Each error code is displayed as a 2-digit number. When less than 10 errors occur, the rest of the buffer is empty (00). See also paragraph Error Codes for a description. · Code 2. Gives the first five errors of the error buffer. See also paragraph Error Codes for a description. · Headphone Volume. Gives the last status of the headphone volume, as set by the customer. The value can vary from 0 (volume is minimum) to 100 (volume is maximum). Change via "MENU", "TV", "SOUND", "HEADPHONE VOLUME". · Dolby. Indicates whether the received transmitter transmits Dolby sound ("ON") or not ("OFF"). Attention: The presence of Dolby can only be tested by the software on the Dolby Signaling bit.

How to Exit CSM Press any key on the RC-transmitter (with exception of the "CHANNEL +/-", "VOLUME", "MUTE" and digit (0-9) keys). 5.2.4 Service Mode of Converter Boards for Ambi Light Purpose To switch on the lamps manually in case I2C-bus triggering fails. The Service Mode can be activated by disconnecting connectors 1M59 and 1M49 and then by shorting for a moment the two solder pads [1] on the Ambi Light Inverter Panel. See figure "Service Mode pads AmbiLight panel".
The microprocessor performs the following tasks: · Dimming of Ambi Light by means of PWM. · Translation of I2C-bus commands to PWM. · Switches the Ambi Light board to protection if needed (in case of protection only the lamps switch off, no set protection is triggered). There are two ways of protection: parallel arcing protection and serial arcing protection. Parallel arcing protection is performed by sensing the switching frequency. In case of short circuit of the transformer output, this frequency > 100 kHz and the board goes into protection. Serial arcing protection is performed by detection of arc in ground wire of the lamp units. In this case, the protection pulse is transmitted via an opto-coupler. Protection can be disabled by short-circuiting diode 6112 or capacitor 2173 or by connecting pin 8 of the microprocessor to ground. Repair Tips In case only one or no lamp unit at all works, probably the +12Vb (12 - 13 V) is not available or the fuse is broken. Check for broken MOSFETS or check if they are switched off properly by the transistors connected to the PWM outputs of the microprocessor.
1
In case the Ambi Light switches off after two seconds, serial arcing or parallel arcing protection is active. Serial arcing protection can be excluded by disconnecting the opto-coupler; check for bad solder joints on transformer or lamp units. Parallel arcing protection can be disabled by grounding pin 8 of the microprocessor. Usually the switching frequency (normally 63 kHz) will then be too high. Possible causes are one MOSFET of the converter has no gate drive or is broken, or there is a short-circuit of the output of the transformer.

Stepwise Start-up
The stepwise start-up method, as known from FTL/FTP sets is not valid any more. The situation for this chassis is as follows: when the TV is in a protection state detected via the Stand-by Processor (and thus blinking an error) and SDM is activated via shortcutting the pins on the SSB, the TV starts up until it reaches the situation just before protection. So, this is a kind of automatic stepwise start-up. In combination with the start-up diagrams below, you can see which supplies are present at a certain moment. Important to know here is, that if e.g. the 3V3 detection fails (and thus error 11 is blinking) and the TV is restarted via SDM, the Stand-by Processor will enable the 3V3, but will not go to protection now. The TV will stay in this situation until it is reset (Mains/AC Power supply interrupted). The abbreviations "SP" and "MP" in the figures stand for: · SP: protection or error detected by the Stand-by Processor. · MP: protection or error detected by the VIPER Main Processor.
Figure 5-3 Service Mode pads AmbiLight panel In this chassis, both single and double fitted boards can be used. The double fitted boards are used in sets with 3 or 4 sided Ambi Light units whereas the single fitted boards are used in sets with 2 sided Ambi Light units. A double fitted board can drive 2 lamp units (6 lamps) and a single fitted board can drive 1 lamp unit (3 lamps). The double fitted boards are supplied by +12Va and +12Vb. The microprocessor is supplied by +12Va. Therefore, if only +12Va is available, lamp unit B will not work. See figure "Building blocks of Converter Board" for details.

All I/O lines have a "high" default state: - Assert the Viper reset. - Sound-Enable and Reset-Audio should remain "high". - NVM power line is "high", no NVM communication possible.
If the protection state was left by short circuiting the SDM pins, detection of a protection condition during startup will stall the startup. Protection conditions in a playing set will be ignored. The protection mode will not be entered.
Initialise I/O pins of the st-by µP, start keyboard scanning, RC detection, P50 decoding. Wake up reasons are "off".

A low to high transition of the signals should occur within a certain time after toggling the standby line. If an observers is detected before the time-out elapses, of course, the process should continue in order to minimize start up time.
