Precautions, Notes, and Abbreviation List

Index of this chapter:

3.1 Safety Instructions

3.2 Warnings

3.3 Notes

3.4 Abbreviation List

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.

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.

3.2 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 Notes

3.3.1 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 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 (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.

3.3.2 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 nano-farads (n 10

• 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.

3.3.3 Spare Parts

For the latest spare part overview, consult your Philips Spare Part web portal.

3.3.4 BGA (Ball Grid Array) ICs

Introduction

For more information on how to handle BGA devices, visit this URL: http://www.atyourservice-magazine.com “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.

3.3.5 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.

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

Precautions, Notes, and Abbreviation List

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. SN is Lysomice, RJ is Kobierzyce), 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 2010 week 10 / 2010 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.

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.

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. Analogue SDM can also be activated by grounding the solder path on the SSB, with the indication “SDM” (see figures Service mode pad - front

back.

• Digital SDM: use the 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.

) and Service mode pad -

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

”).

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).

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 the standby processor and make the TV start up to the step just before protection. See section “5.3 Start-up

”.

• To start the blinking LED procedure where only LAYER 2 errors are displayed. (see also section “5.5 Error Codes

How to Activate SAM

Via a standard RC transmitter: Key in the code “062596” directly followed by the “INFO” or “OK” 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

• Hardware Info. – A. SW Version. Displays the software version of the

main software (example: QF1XX-1.2.3.4 = AAABB_X.Y.W.Z).

• AAA= the chassis name.

• BB= Product ID.

• 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

Figure 5-3 Location of Display Option Code sticker

compatible with a lower number).

– B. Standby processor version. Displays the software

version of the standby 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. The update can be done via the NVM editor available in SAM.

• Operation hours. Displays the accumulated total of operation hours (not the standby 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 “OK” button) pressed here, followed by the “OK” button, the error buffer is reset.

• Alignments. This will activate the “ALIGNMENTS” submenu. See Chapter 6. Alignments

• Options numbers. Extra features for Service. For more info regarding option codes, see chapter 6. 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.

• Initialise NVM. The moment the processor recognizes a corrupted NVM, the “initialise 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).

– Initialise the NVM.

• Store - go right. All options and alignments are stored when pressing “cursor right” or the “OK” button.

• Software maintenance. – SW Events. In case of specific software problems, the

development department can ask for this info.

– HW Events. In case of specific software problems, the

development department can ask for this info :

- Event 26: refers to a power dip, this is logged after the TV set reboots due to a power dip.

- Event 17: refers to the power OK status, sensed even before the 3 x retry to generate the error code.

• Test settings. For development purposes only.

• RF4CE pairing tables. Clear paired remote control. Repairing (coldboot of platform possibly needed) can be done by pressing the red/blue hot keys simultaneously for a few seconds.(be sure the distance between the remote control and TV set RF4CE receiver is less then 30cm). Message like “Pairing successful”, confirms the match-make.

• Development 1 file versions. Not useful for Service purposes, this information is mainly used by the development department.

• Development 2 file versions. Not useful for Service purposes, this information is mainly used by the development department.

• Upload to USB. To upload several settings from the TV to an USB stick, which is connected to the SSB. The items are “Personal settings”, “Option codes”, “Alignments”, “Identification data” (includes the set type and prod code + all 12NC like SSB, display, boards), “History list”. The “All” item supports the upload of all several items at once.

A directory “repair\” will be created in the root of the USB stick.

To upload the settings, select each item separately, press “cursor right” (or the “OK” button), confirm with “OK” and

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 6. Alignments

for details. To adapt this option, it’s advised to use ComPair (the correct values for the options can be found in Chapter 6. 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” (or "HOME") button and “XXX” (where XXX is the 3 digit decimal display code as mentioned on the sticker in the set). 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 (Standby) as an indication that the RC sequence was correct. After the display option is changed in the NVM, the TV will go to the Standby 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.

wait until the message “Done” appears. In case the download to the USB stick was not successful, “Failure” will be displayed. 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 into another TV or other SSB. Uploading is of course only possible if the software is running and preferably 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. Important remark : to upload the “channel list”, select “Home” => “Setup” => “TV settings” => “General settings” => “Channel list copy” => “Copy to USB”.The procedure is also described in the (electronic) user manual.

• Download from USB. To download several settings from the USB stick to the TV, same way of working needs to be followed as described in “Upload to USB”. The “All” item supports to download all several items at once. Important remark : to download the “channel list”, select “Home” => “Setup” => “TV settings” => “General settings” => “Channel list copy” => “Copy to TV”. The procedure is also described in the (electronic) user manual.

• NVM editor. For Smart TV the set “Type number” must be

entered correctly. Also the “Production code” (factory location code), “12NC SSB”, “12NC display” and “12NC supply” can be entered here via the RC-transmitter.Be sure the cursor is put fully to the left (use back key) of the dialog box before enter the new data. Correct data can be found on the side/rear sticker.

How to Navigate

• In SAM, the menu items can be selected with the “CURSOR UP/DOWN” key on the RC-transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the “CURSOR UP/DOWN” key to display the next/previous menu items.

• With the “CURSOR LEFT/RIGHT” keys, it is possible to: – (De) activate the selected menu item. – (De) activate the selected sub menu.

• With the “OK” key, it is possible to activate the selected action.

How to Exit SAM

Use one of the following methods:

• Switch the TV set to STAND-BY via the RC-transmitter.

• Via a standard RC-transmitter, key in “00” sequence, or select the “BACK” key.

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.

Provided CSM is activated, every menu from CSM can be used as check for the back end chain video.So for all CSM content displayed, it could be determined that the back end video chain is working.

When CSM is activated and there is a USB stick connected to the TV set, the software will dump the CSM content to the USB stick. The file (CSM_model number_serial number.txt) will be saved in the root of the USB stick. This info can be handy if no information is displayed.

Additional in CSM mode (with USB stick connected), pressing “OK” will create an extended CSM dump file on the USB stick. This file (Extended_CSM_model number_serial number.txt) contains:

• The normal CSM dump information,

• All items (from SAM “load to USB”, but in readable format),

• Operating hours,

• Error codes,

• SW/HW event logs.

To have fast feedback from the field, a flashdump can be requested by development. When in CSM, push the “red” button and key in serial digits ‘2679’ (same keys to form the word ‘COPY’ with a cellphone). A file “Dump_model number_serial number.bin” will be written on the connected USB device. This can take 1/2 minute, depending on the quantity of data that needs to be dumped.

Also when CSM is activated, the LAYER 1 error is displayed via blinking LED.(see also section 5.5 Error Codes

How to Activate CSM

Key in the code “123654” via the standard RC transmitter.

2012-Sep-14

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, 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, the set type content has to be re-written to NVM.The update can be done via the NVM editor available in SAM.

• Production code. Displays the production code (the serial number) of the TV. Note that if an NVM is replaced or is initialized after corruption, the production code content has to be re-written to NVM. The update can be done via the NVM editor available in SAM.

5.4 Service Tools

5.4.1 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

2. ComPair allows very detailed diagnostics and is therefore

3. ComPair speeds up the repair time since it can

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.

Caution: It is compulsory to connect the TV to the PC as shown in the picture above (with the ComPair interface in between), as the ComPair interface acts as a level shifter. If one connects the TV directly to the PC (via UART), ICs can be blown!

How to Order

ComPair II order codes:

• ComPair II interface: 3122 785 91020.

• Software is available via the Philips Service web portal.

• ComPair UART interface cable for QF1x.x.

5.5 Error Codes

5.5.1 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.

• If no errors are there, the LED should not blink at all in

CSM or SDM. No spacer must be displayed as well.

• 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

– 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.

• In CSM mode. – When entering CSM: error LAYER 1 will be displayed

• In SDM mode. – When SDM is entered via Remote Control code or the

• Error display on screen. – In CSM no error codes are displayed on screen. – In SAM the complete error list is shown.

Basically there are three kinds of errors:

• Errors detected by the Standby software which lead to protection. These errors will always lead to protection and an automatic start of the blinking LED LAYER 1 error. (see section “5.6 The Blinking LED Procedure

• Errors detected by the Standby software which not lead to protection. In this case the front LED should blink the involved error. See also section “5.5 Error Codes

Error Buffer”. Note that it can take up several minutes

before the TV starts blinking the error (e.g. LAYER 1 error = 2, LAYER 2 error = 15 or 53).

• Errors detected by main software (MIPS). In this case the error will be logged into the error buffer and can be read out via ComPair, via blinking LED method LAYER 1-2 error, or in case picture is visible, via SAM.

5.5.2 How to Read the Error Buffer

Use one of the following methods:

• On screen via the SAM (only when a picture is visible). E.g.: – 00 00 00 00 00: No errors detected – 23 00 00 00 00: Error code 23 is the last and only

– 37 23 00 00 00: Error code 23 was first detected and

– Note that no protection errors can be logged in the

•Via ComPair.

5.5.3 How to Clear the Error Buffer

Use one of the following methods:

• By activation of the “RESET ERROR BUFFER” command in the SAM menu.

• If the content of the error buffer has not changed for 50+ hours, it resets automatically.

5.5.4 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.

Monitored by

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) There are several mechanisms of error detection:

• Via error bits in the status registers of ICs.

• Via polling on I/O pins going to the standby processor.

• Via sensing of analog values on the standby processor or the Mips.

• Via a “not acknowledge” of an I

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.

Extra Info

• Rebooting. When a TV is constantly rebooting due to internal problems, most of the time no errors will be logged or blinked. This rebooting can be recognized via a ComPair interface and Hyperterminal (for Hyperterminal settings, see section “5.8 Fault Finding and Repair Tips

Logging). It’s shown that the loggings which are generated

by the main software keep continuing.

• Error 13 (I

C bus M3, SSB + SRF bus blocked). Current situation: when this error occurs, the TV can reboot due to the blocked bus. The best way for further diagnosis here, is to check the logging output.

• Error 14 (I

C bus M2, BE bus blocked). Current situation: when this error occurs. The best way for further diagnosis here, is to check the logging output.

• Error 18 (I

C bus M1, FE bus blocked). Current situation: when this error occurs. The best way for further diagnosis here, is to check the logging output.

• Error 15 (Fusion doesn’t boot). Indicates that the main processor was not able to read his bootscript. This error will point to a hardware problem around the Fusion (supplies not OK, Fusion device completely dead, link between Mips and Stand-by Processor broken, etc...) Other root causes for this error can be due to hardware problems regarding the DDR’s and the bootscript reading from the Fusion device.

• Error 16 (12V). This voltage is made in the power supply and results in protection (LAYER 1 error = 3) in case of absence. When SDM (maintain grounding continuously) is activated we see blinking LED LAYER 2 error = 16.

• Error 17 (Display Supply). Here the status of the “Power OK” is checked by software, no protection will occur during failure of the display supply, only error logging. LED blinking of LAYER 1 error = 3 in CSM, in SDM this gives LAYER 2 error = 17.

• Error 23 (HDMI mux). When there is no I

C communication towards the HDMI mux after start-up, LAYER 2 error = 23 will be logged and displayed via the blinking LED procedure if SDM is switched on.

• Error 24 (I2C switch). When there is no I communication towards the I

C switch, LAYER 2

error = 24 will be logged and displayed via the blinking LED procedure when SDM is switched on.

• Error 27 (Channel dec DVB-T2). When there is no I

C communication towards the DVB-T channel decoder, LAYER 2 error = 27 will be logged and displayed via the blinking LED procedure if SDM is switched on.

• Error 28 (Channel dec DVB-S2). When there is no I

C communication towards the DVB-S channel decoder, LAYER 2 error = 28 will be logged and displayed via the blinking LED procedure if SDM is switched on.
