Safety Instructions

3.1

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.

4.2 Service Positions

For easy servicing of a TV set, the set should be put face down on a soft flat surface, foam buffers or other specific workshop tools. Ensure that a stable situation is created to perform measurements and alignments. When using foam bars take care that these always support the cabinet and never only the display. Caution: Failure to follow these guidelines can seriously damage the display! Ensure that ESD safe measures are taken.

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: Color 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.

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 5-1

• Analogue SDM: use the standard RC-transmitter and key in the code “062596”, 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. Analogue SDM can also be activated by grounding for a moment the solder path on the SSB, with the indication “SDM” (see Service mode pad

• Digital SDM: use the standard 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.

EN 25Q552.2L LA 5.

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 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

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. To adapt this option, it’s advised to use ComPair (the correct values for the options can be found in Chapter 6. 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 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.

The items are “Channel list”, “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 to upload all several items at once.

First a directory “repair\” has to 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 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.

• 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”. 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. The “All” item supports to download all several items at once.

• NVM editor. For NET TV the set “type number” must be entered correctly. Also the production code (AG code) can be entered here via the RC-transmitter. Correct data can be found on the side/rear sticker.

• 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.

When in this chassis CSM is activated, a test pattern 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 PNX51X0 (located on the 200Hz board as part of the display). So if this test pattern is shown, it could be determined that the back end video chain (PNX51X0 and display) is working.For TV sets without the PNX51X0 inside, every menu from CSM will be used as check for the back end chain video.

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.

When in CSM mode (and a 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. 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 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, this set type has to be re-written to NVM. ComPair will foresee in a possibility to do this. The update can also 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, this production code has to be re-written to NVM. ComPair will foresee in a possibility to do this. The update can also be done via the NVM editor available in SAM.

• 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).

• 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 is the 12nc number of the SSB.

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

• 12NC supply. Shows the 12NC of the power supply.

• 12NC 200Hz board. Shows the 12NC of the 200Hz Panel (when present).

• 12NC AV PIP. Shows the 12NC of the AV PIP board (when present).

Service Modes, Error Codes, and Fault Finding

How to Exit CSM

Press “MENU” (or "HOME") / “Back” key on the RC-transmitter.

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 SDM solder path 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. Caution: in case the start-up in this mode with a faulty FET 7U0X is done, you can destroy all IC’s supplied by the +1V8 and +1v1, due to overvoltage (12V on XVX-line). It is recommended to measure first the FET

7U0X or others FET’s on shortcircuit before activating SDM via the service pads.

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.
