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 MΩ and 12 MΩ.

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.

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 kΩ).

• Resistor values with no multiplier may be indicated with either an “E” or an “R” (e.g. 220E or 220R indicates 220 Ω).

• All capacitor values are given in micro-farads (μ=× 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.

3.2 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

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 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.

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 Hotel mode

Before the service modes can be activated, the set needs to be switched into normal consumer mode (MTV-Mode) first. Use an iTV setup remote control (type: RC2573/01, 12nc: 3139 228 88782) to key in the code ‘024995’ (slowly) directly followed by the MENU button. The text messages “TV Is Now In MTV Mode” and “Please Do A Cold Start!” appears on the screen. Disconnect the set for a few seconds from the mains supply, reconnect the set to the mains supply again. The set is now in the normal consumer mode (MTV-Mode). After repair, place the set into hotel mode (iTV-Mode) again. Key-in the same code on the remote control as described above. The text message “TV Is Now In ITV Mode” appears. A cold start must be performed as described above. The set is now in the hotel mode (iTV-Mode) again.

• All picture settings at 50% (brightness, colour, contrast).

• All sound settings at 50%, except volume at 25%.

• All service-unfriendly modes (if present) are disabled, like: – (Sleep) timer. – Child/parental lock. – Picture mute (blue mute or black mute). – Automatic volume levelling (AVL). – Skip/blank of non-favourite pre-sets.

How to Activate SDM

For this chassis there are two kinds of SDM: an analogue SDM and a digital SDM. Tuning will happen according table “SDM Default Settings”.

• Analogue 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.

• Analogue SDM can also be activated by shorting for a moment the two solder pads [1] (see Figure 5-1 SSB, with the indication “SDM”. Activation can be performed in all modes, except when the set has a problem with the Stand-by Processor.

5.3 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 ComPair

5.3.1 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 Stepwise Start-up

• To override SW protections detected by MIPS. See also section Error Codes

• To start the blinking LED procedure (not valid for protections detected by stand-by software).

Figure 5-1 Service mode pads

After activating this mode, “SDM” will appear in the upper right corner of the screen.

How to Navigate

By pressing 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.

5.3.2 Service Alignment Mode (SAM)

Purpose

• To perform (software) alignments.

• To change option settings.

• To easily identify the used software version.

• To view operation hours.

• To display (or clear) the error code buffer.

How to Activate SAM

Via a standard RC transmitter: key in the code “062596” directly followed by the “INFO/i+” button. After activating SAM with this method a service warning will appear on the screen, to continue press the red button on the RC.

Contents of SAM:

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

main software (example: Q53HE-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 maximal 10 errors). The most recent error is displayed at the upper left (for an error explanation see section Error Codes

• Reset Error Buffer. By pressing “cursor right” (or the “OK button) 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. For more info regarding option codes, see chapter Alignments Note that if the option code numbers are changed, it has to be confirmed with the “OK” button before storing the options. Otherwise any changes will be lost.

• Initialise NVM. The moment the processor recognizes a corrupted NVM, the “initialize NVM” line will be highlighted. Now, two options are available (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 NVM is corrupted, or the NVM has been replaced, there is a high possibility that the set will not display a picture anymore because the display code is not correct. So, before initializing the NVM via the SAM, the set should display a picture and therefore the correct display option is a necessity.

2009-Dec-04

Refer to chapter Alignments

for details. To adapt this option, the ComPair tool can be used (the correct HEX values for the options can be found in chapter 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 (see table Table 6-3 in chapter Alignments

, or sticker on the side/bottom of the cabinet). 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.

Figure 5-2 Location of Display Option Code sticker

• Store - go right. All options and alignments are stored

when pressing “cursor right” (or the “OK” button) and then the “OK”-button.

• SW Maintenance.

– SW Events. Not useful for Service purposes. In case

of specific software problems, the development department can ask for this information.

– HW Events. Not useful for Service purposes. In case

of specific software problems, the development department can ask for this info.

• Test settings. For development purposes only.

• Upload to USB. To upload several settings from the TV to

a USB stick, which is connected to the Side I/O. The items are “Channel list”, “Personal settings”, “Option codes”, “Display-related alignments” and “History list”. First a directory “repair” has to be created in the root of the USB stick. To upload the settings each item has to be selected

separately, press “cursor right” (or the “OK button), confirm with “OK” and wait until “Done” appears. In case the download to the USB stick was not successful “Failure” will appear. In this case, check if the USB stick is connected properly and if the directory “repair” is present in the root of the USB stick. Now the settings are stored onto the USB stick and can be used to download onto another TV or

other SSB. Uploading is of course only possible if the software is running and the set is displaying a picture. This method is created to be able to save the customer’s TV settings and to store them into another SSB.

• Download from USB. To download several settings from

the USB stick to the TV. Same way of working as with uploading. To make sure that the download of the channel list from USB to the TV is executed properly, it is necessary to restart the TV and tune to a valid preset if necessary. Note: The “History list item” can not be downloaded from USB to the TV. This is a “read-only” item. In case of specific problems, the development department can ask for this info.

How to Navigate

• In SAM, 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

Service Modes, Error Codes, and Fault Finding

EN 27Q522.1HE LA 5.

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:

• Press the “MENU” button on the RC-transmitter.

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

5.3.3 Customer Service Mode (CSM)

Purpose

When a customer is having problems with his TV-set, he can call his dealer or the Customer Help desk. 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 colour bar test pattern will be visible for 5 seconds. This test pattern is generated by the Pacific3. So if this test pattern is displayed, the correct running of the back end video chain (Pacific3, LVDS, and display) can be determined. In case of a set with DFI panel, an extra test picture is generated. A Pacific3 test picture for 3 seconds and then the DFI EPLD test picture for another 3 seconds will be generated. With this extra test picture it is possible to determine if the DFI panel is working properly. Also new in this chassis: 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 information can be useful if the set is not displaying a picture. Another new item in this chassis is when CSM is activated, the complete error-buffer content will be shown via the blinking LED procedure.

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, can be navigated through the menus.

Contents of CSM

• Set Type. This information is very helpful for a help desk/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.

• Code 1. Gives the last 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 section

Error Codes

• Code 2. Gives the first five errors of the error buffer. See also section Error Codes

for a description.

• 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).

• 12NC SSB. Gives an identification of the SSB as stored in NVM. Note that if an NVM is replaced or is initialized after corruption, this identification number has to be re-written to NVM. ComPair will foresee in a possibility to do this. This identification number consists of 14 characters and is built up as follows:

- Seven last characters of the 12NC of the SSB itself.

- the serial number of the SSB, which consists of seven digits. Both can be found on a sticker on the PWB of the SSB itself. The format of the identification number is then as follows: <last seven characters of 12NC of SSB><serial number of SSB> (total fourteen characters).

• Installed date. Indicates the date of the first installation of the TV. This date is acquired via time extraction.

• Digital Natural Motion. Gives the status of the Digital Natural Motion setting as set by the customer. Remark: a customer can choose between “OFF”, “MINIMUM” and “MAXIMUM”, but in CSM this item will only show “OFF” or “ON” (“ON” in case the customer has chosen “MINIMUM” or “MAXIMUM”)

• Pixel Plus. Gives the last status of the Perfect Pixel HD setting, as set by the customer. Possible values are “ON” and “OFF”. See DFU on how to change this item.

• DNR. Gives the last status of the Noise reduction setting, as set by the customer. Possible values are “OFF”, “MINIMUM”, “MEDIUM” and “MAXIMUM”. See DFU on how to change this item.

• Noise Figure. Gives an indication of the signal quality for the selected transmitter. Possible values are “BAD”, “AVERAGE”, “GOOD“ and “DIGITAL”. In case of a digital channel, this item will never indicate: “BAD”, “GOOD” or “AVERAGE” but only displays “DIGITAL”.

• 12NC Display. Shows the 12NC of the display.

• MPEG4 (blue to toggle).

• Head phone Volume. Gives the last status of the head phone volume, as set by the customer. The value can vary from 0 (volume is minimum) to 100 (volume is maximum). See DFU on how to change this item.

• Surround Mode. Indicates the by the customer selected sound mode (or automatically chosen mode). Possible values are “STEREO” and “VIRTUAL DOLBY SURROUND”. It can also have been selected automatically by signalling bits (internal software). See DFU on how to change this item.

• AVL. Indicates the last status of AVL (Automatic Volume Level) as set by the customer: See DFU on how to change this item.

• Delta Volume. Indicates the last status of the delta volume for the selected preset as set by the customer: from “-12” to “+12”. See DFU on how to change this item.

• Volume. Indicates the last status of the volume for the selected preset as set by the customer: from “0” to “100”. See DFU on how to change this item.

• Balance. Indicates the last status of the balance for the selected preset as set by the customer: from “-10” to “+10”. See DFU on how to change this item.

• Preset Lock. Indicates if the selected preset has a child lock: “LOCKED” or “UNLOCKED”. See DFU on how to change this item.

• Child Lock. Indicates the status of the Child lock. See DFU on how to change this item.

5.4 Stepwise Start-up

There are two possible situations: one for protections detected by the stand-by software and one for protections detected by the main software. When the TV is in a protection state due to an error detected by stand-by software (and thus blinking an error) and SDM is activated via short-circuiting 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 8 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). Caution: in case the start up in this mode with a faulty FET 7U08 is done, you can destroy all ICs supplied by the +3V3, due to over-voltage. It is recommended to measure first the

FET 7U08 on short-circuit before activating SDM via the service pads. When the TV is in protection state due to an error detected by main software (MIPS protection) and SDM is activated via short-cutting the service pads on the SSB, the TV starts up and ignores the error. In this chassis, only error “63” (power-ok) is a MIPS protection and already displays the failure via blinking LED.

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 MIPS Main

Processor.

The a vailability of the supplies is checked through detect

signals going to the st-by µP. These signals are available

for +12V and +5V (combined as AND function, called

detect-5V-12V) and for +1V2 and +3V3 (combined as

AND function, called detect-1V2-2V5-3V). A low to high

transition of the signals should occur within a certain time

after toggling the standby line. If an observer is detected

before the time-out elapses, of course, the process

should continue in order to minimize start up time.
