Safety Instructions, Warnings, and Notes
2. Safety Instructions, Warnings, and Notes
Index of this chapter: 2.1 Safety Instructions 2.2 Warnings 2.3 Notes · 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", "Virtual Dolby Digital" and the "doubleD 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 ( = × 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.

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.
2.2
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.
2.3.4
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

2.3.1
Notes
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 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).
Directions for Use
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

MODEL
: 32PF9968/10

MADE IN BELGIUM 220-240V ~ 50/60Hz 128W VHF+S+H+UHF
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.

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.

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 "SDM Default Settings". · Analog SDM: 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. · Digital SDM: use the standard RC-transmitter and key in the code "062593", 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. · Analog SDM can also be activated by shorting for a moment the two solder pads (see figure "Service mode pads") on the SSB, with the indication "SDM".
5.1
Test Points
As most signals are digital, it will be difficult to measure waveforms with a standard oscilloscope. However, 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: Colour bar signal. · Audio: 3 kHz left, 1 kHz right.

5.2
Service Modes
Service Default mode (SDM) and Service Alignment Mode (SAM) offers 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 "5.4.1 ComPair").
H_16770_100.eps 130707
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 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 section "5.3 Stepwise Start-up". · To start the blinking LED procedure where only layer 2 errors are displayed. (see also section "5.5 Error Codes") Specifications Table 5-1 SDM default settings Default system PAL B/G 5.2.2
Figure 5-1 Service mode pads 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" button is pressed 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 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 red button on the RC.

Contents of SAM: · Hardware Info. A. SW Version. Displays the software version of the main software (example: Q591E-1.2.3.4 = AAAAB_X.Y.W.Z). · AAAA= the chassis name. · B= the region: A= AP, E= EU, L= LatAm, U = US. For AP sets it is possible that the Europe software version is used. · 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. 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 maximum 10 errors). The most recent error is displayed at the upper left (for an error explanation see section "5.5 Error Codes"). · Reset Error Buffer. When "cursor right" (or the "OK button) is pressed and then the "OK" button is pressed, the error buffer is reset. · Alignments. This will activate the "ALIGNMENTS" submenu. · Dealer Options. Extra features for the dealers. · Options. Extra features for Service. For more info regarding option codes, see chapter 8 "Alignments". 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. 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. Refer to chapter 8 "Alignments" for details. To adapt this option, it's advised to use ComPair (the correct HEX values for the options can be found in chapter 8 "Alignments") 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" button and "XXX" (where XXX is the 3 digit decimal display code as mentioned in table "Option code overview" in chapter 8 "Alignments"). 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.

Shows the 12NC of the supply. 12NC "bolt-on". Shows the 12NC of the "BOLT-ON"module.
Switch the set to STAND-BY via the RC-transmitter.
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 in this chassis CSM is activated, a testpattern will be displayed during 5 seconds (1 second Blue, 1 second Green and 1 second Red, then again 1 second Blue and 1 second Green). This test pattern is generated by the PNX5100. So if this test pattern is shown, it could be determined that the back end video chain (PNX5100, LVDS, and display) of the SSB is working. To determine if the MPEG4-circuit is working (in case of an MPEG4-set), push the "MUTE" button during CSM to display another test pattern. This is a forced input selection to make sure the test pattern is visible. If this test pattern is not shown, it is possible that the settings are not correct (for instance in SAM the MPEG4-option is "NOT PRESENT"). The display of this test pattern is a toggle function, pressing the "MUTE" key again removes this test pattern. When CSM is activated and there is a USB stick connected to the TV, the software will dump the complete CSM content to the USB stick. The file (Csm.txt) will be saved in the root of the USB stick. This info can be handy if no information is displayed. Also when CSM is activated, the layer 1 error is displayed via blinking LED. Only the latest error is displayed. (see also section "5.5 Error Codes"). 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 (or the scroll wheel) on the RC-transmitter, can be navigated through the menus. Contents of CSM The contents are reduced to 3 pages: General, Software versions and Quality items. The group names itself are not shown anywhere in the CSM menu. General · 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-set. 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 in 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 in possibility to do this. · Installed date. Indicates the date of the first installation of the TV. This date is acquired via time extraction. · Options 1. Gives the option codes of option group 1 as set in SAM (Service Alignment Mode). · Options 2. Gives the option codes of option group 2 as set in SAM (Service Alignment Mode).

Service Modes, Error Codes, and Fault Finding 5.3 Stepwise Start-up
When the TV is in a protection state due to an error detected by stand-by software (error blinking is displayed) 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 is, that if e.g. the 3V3 detection fails and thus error layer 2 = 18 is blinking while the TV is restarted via SDM, the Stand-by Processor will enable the 3V3, but the TV set will not go to protection now. The TV will stay in this situation until it is reset (Mains/AC Power supply interrupted). Caution: in case the start up in this

Semi Standby
The assumption here is that a fast toggle (<2s) can only happen during ON -> SEMI -> ON. In these states, the AVC is still active and can provide the 2s delay. If the transition ON-> SEMI>STBY -> SEMI -> ON can be made in less than 2s, the semi -> stby transition has to be delayed until the requirement is met . Wait until previous on-state is left more than 2 seconds ago. (to prevent LCD display problems)

Constraints taken into account:
- Display may only be started when valid LVDS output clock can be delivered by the AVC . - Between 5 and 50 ms after power is supplied, display should receive valid lvds clock . - minimum wait time to switch on the lamp after power up is 200ms. - To have a reliable operation of the backlight, the backlight should be driven with a PWM duty cycle of 100% during the first second. Only after this first one or two seconds, the PWM may be set to the required output level (Note that the PWM output should be present before the backlight is switched on). To minimize the artefacts, the picture should only be unblanked after these first seconds. action holder: AVC action holder: St-by autonomous action
Semi Standby
The assumption here is that a fast toggle (<2s) can only happen during ON ->SEMI ->ON. In these states, the AVC is still active and can provide the 2s delay. If the transition ON -> SEMI->STBY -> SEMI -> ON can be made in less than 2s, the semi -> stby transition has to be delayed until the requirement is met . Wait until previous on-state is left more than 2 seconds ago. (to prevent LCD display problems)
CPipe already generates a valid output clock in the semi -standby state: display startup can start immediately when leaving the semi-standby state.

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.

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 can be 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 5-2 error code overview). LAYER 1 errors are one digit errors. LAYER 2 errors are 2 digit errors. In protection mode. From consumer mode: LAYER 1. From SDM mode: LAYER 2. Fatal errors, if I2C bus is blocked and the set reboots, CSM and SAM are not selectable. From consumer mode: LAYER 1. From SDM mode: LAYER 2. Important remark: For all errors detected by MIPS which are fatal => rebooting of the TV set (reboot starts after LAYER error 1 blinking), one should short the solder paths at startup from the power OFF state by mains interruption and not via the power button to trigger the SDM via the hardware pins. 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 In "Display error mode", set 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.
