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

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.

2.2 Warnings

• All ICs and many other semiconductors are susceptible to electrostatic discharges (ESD w). Careless handling during repair can reduce life drastically. Make sure that, during repair, you are connected with the same potential as the mass of the set by a wristband with resistance. Keep components and tools also at this same potential. Available ESD protection equipment: – Complete kit ESD3 (small tablemat, wristband,

connection box, extension cable and earth cable) 4822 310 10671.

– Wristband tester 4822 344 13999.

• Be careful during measurements in the high voltage section.

• Never replace modules or other components while the unit is switched "on".

• When you align the set, use plastic rather than metal tools. This will prevent any short circuits and the danger of a circuit becoming unstable.

2.3 Notes

2.3.1 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 (see chapter 5) with a color bar signal and stereo sound (L: 3 kHz, R: 1 kHz unless stated otherwise) and picture carrier at 475.25 MHz for PAL, or

61.25 MHz for NTSC (channel 3).

• Where necessary, measure the waveforms and voltages

with (D) and without (E) aerial signal. Measure the voltages in the power supply section both in normal operation (G) and in stand-by (F). These values are indicated by means of the appropriate symbols.

2.3.2 Schematic Notes

• All resistor values are in ohms, and the value multiplier is often used to indicate the decimal point location (e.g. 2K2 indicates 2.2 kohm).

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

• All capacitor values are given in micro-farads (μ= x10 nano-farads (n= x10

• Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).

• An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values.

• The correct component values are listed in the Spare Parts List. Therefore, always check this list when there is any doubt.

2.3.3 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.

2.3.4 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.

), or pico-farads (p= x10

-12

-6

Safety Instructions, Warnings, and Notes

• 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.

2.3.5 Alternative BOM identification

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.

EN 7EJ3.0U LA 2.

Identification: The bottom line of a type plate gives a 14-digit

serial number. Digits 1 and 2 refer to the production center (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.

2.3.6 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.

Figure 4-6 Foam bars

The foam bars (order code 3122 785 90580 for two pieces) can be used for all types and sizes of Flat TVs. See figure “Foam bars” for details. Sets with a display of 42” and larger, require four foam bars [1]. Ensure that the foam bars are always supporting the cabinet and never only the display. Caution: Failure to follow these guidelines can seriously damage the display! By laying the TV face down on the (ESD protective) foam bars, a stable situation is created to perform measurements and alignments. By placing a mirror under the TV, you can monitor the screen.

5.1 Test Points

As most signals are digital, it will be almost impossible to measure waveforms with a standard oscilloscope. Therefore, waveforms are not given in this manual. Several key ICs are capable of generating test patterns, which can be controlled via ComPair. In this way it is possible to determine which part is defective.

Perform measurements under the following conditions:

• Service Default Mode.

• Video: Color bar signal.

• Audio: 3 kHz left, 1 kHz right.

5.2 Service Modes

Service Default Mode (SDM) and Service Alignment Mode (SAM) offer several features for the service technician, while the Customer Service Mode (CSM) is used for communication between a Customer Helpdesk and a customer.

There is also the option of using ComPair, a hardware interface between a computer (see requirements below) and the TV chassis. It offers the ability of structured troubleshooting, test pattern generation, error code reading, software version readout, and software upgrading.

Minimum requirements for ComPair: a Pentium processor, Windows 95/98, and a CD-ROM drive (see also paragraph “ComPair”).

Remark: as the Hotel Mode is a User Mode, rather than a Service Mode, we have put the description in Chapter 3, Directions for Use.

• Tuning frequency 61.25 MHz for NTSC: The TV shall tune to physical channel 3 only if channel 3 is an analog channel or if there is no channel 3 installed in the channel map. If there is a digital channel installed in channel 3, then the frequency to which the set will tune, would be as specified in the channel map and could be different from the one corresponding to the physical channel 3.

• All picture settings at 50% (brightness, color, 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). – Auto switch "OFF" (when no video signal was received

for 10 minutes). – Skip/blank of non-favorite pre-sets. – Smart modes. – Auto store of personal presets. – Auto user menu time-out.

How to Activate SDM

Use one of the following methods:

• Use the standard RC-transmitter and key in the code “062596”, directly followed by the “MENU” button. Note: It is possible that, together with the SDM, the main menu will appear. To switch it "OFF", push the “MENU” button again.

• Short for a moment the two solder pads [1] on the SSB, with the indication “SDM”. They are located on top of the SSB. Activation can be performed in all modes, except when the set has a problem with the Stand-by Processor. See figure “SDM and SPI service pads”.

SDMSPI

5.2.1 Service Default Mode (SDM)

Purpose

• To create a pre-defined setting, to get the same measurement results as given in this manual.

• To override SW protections (only applicable for protections detected by stand-by processor) and make the TV start up to the step just before protection (a sort of automatic stepwise start up). See paragraph “Stepwise Start Up”.

• To start the blinking LED procedure (not valid in protection mode).

After activating this mode, “SDM” will appear in the upper right corner of the screen (if you have picture).

How to Navigate

When you press the “MENU” button on the RC transmitter, the set will toggle between the SDM and the normal user menu (with the SDM mode still active in the background).

How to Exit SDM

Use one of the following methods:

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

• Via a standard customer RC transmitter: key in “00”sequence.

EN 18 EJ3.0U LA5.

Service Modes, Error Codes, and Fault Finding

5.2.2 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” button. After activating SAM with this method a service warning will appear on the screen, you can continue by pressing the red button on the RC.

Contents of SAM:

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

of the VIPER software (main software) (example: EJ30U_0.77.0.0 = AAAAB_X.Y.W.Z_NNNNN).

• AAAA= the chassis name.

• B= the region: A= AP, E= EU, L= Latam, U = US.

• X.Y.W.Z= the software version, where X is the main version number (different numbers are not compatible with one another) and Y is the sub version number (a higher number is always compatible with a lower number). The last two digits are used for development reasons only, so they will always be zero in official releases.

• NNNNN= last five digits of 12nc code of the software.

– B. SBY PROC Version. Displays the software version

of the stand-by processor.

– C. Production Code. Displays the production code of

the TV, this is the serial number as printed on the back of the TV set. Note that if an NVM is replaced or is initialized after corruption, this production code has to be re-written to NVM. ComPair will foresee in a possibility to do this.

• Operation Hours. Displays the accumulated total of operation hours (not the stand-by hours). Every time the TV is switched "ON/OFF", 0.5 hours is added to this number.

• Errors. (Followed by maximal 10 errors). The most recent error is displayed at the upper left (for an error explanation see paragraph “Error Codes”).

• Defective Module. Here the module that generates the error is displayed. If there are multiple errors in the buffer, which are not all generated by a single module, there is probably another defect. It will then display the message “UNKNOWN” here.

• Reset Error Buffer. When you press “cursor right” and then the “OK” button, the error buffer is reset.

• Alignments. This will activate the “ALIGNMENTS” submenu.

• Dealer Options. Extra features for the dealers.

• Options. Extra features for Service.

• Initialize NVM. When an NVM was corrupted (or replaced) in the former EMG based chassis, the microprocessor replaces the content with default data (to assure that the set can operate). However, all preferences and alignment values are gone now, and option numbers are not correct. Therefore, this was a very drastic way. In this chassis, the procedure is implemented in another way: The moment the processor recognizes a corrupted NVM, the “initialize NVM” line will be highlighted. Now, you can do two things (dependent of the service instructions at that moment): – Save the content of the NVM via ComPair for

development analysis, before initializing. This will give the Service department an extra possibility for diagnosis (e.g. when Development asks for this).

– Initialize the NVM (same as in the past, however now it

happens conscious).

Note: When you have a corrupted NVM, or you have replaced the NVM, there is a high possibility that you will not have picture any more because your display option is not correct. So, before you can initialize your NVM via the SAM, you need to have picture and therefore you need the correct display option. To adapt this option, you can use ComPair (the correct HEX values for the options can be found in the table below) 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 by “XXX” (where XXX is the 3 digit decimal display option code as mentioned in the first column of the next table). 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.

• Store. All options and alignments are stored when pressing “cursor right” 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 info.

– HW Events. Not functional at the moment this manual

is released, description will be published in an update manual if the function becomes available.

• Upload to USB. Write the channel list and the settings to a USB device.

• Download from USB. Retrieve the channel list and the settings from a USB device.

How to Navigate

• In SAM, you can select the menu items 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 submenu.

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.

Note: As long as SAM is activated, it is not possible to change a channel. This could hamper the White Point alignments because you cannot choose your channel/frequency any more. Workaround: after you have sent the RC code “062596 INFO” you will see the service-warning screen, and in this stage it is still possible to change the channel (so before pressing the “OK” button).

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.

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 RC transmitter, you can navigate through the menus.

Contents of CSM

• CSM 1 – 1.3. Set type: Model number of the set. 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. (*)

– 1.4. Production Code: Displays the production code

(the serial number) of the TV. (*)

– 1.5. Code 1: Gives the latest five errors of the error

buffer. As soon as the built-in diagnose software has detected an error, the buffer is adapted. The last occurred error is displayed on the leftmost position. Each error code is displayed as a 2-digit number. When less than 10 errors occur, the rest of the buffer is empty (00). See also paragraph Error Codes for a description.

– 1.6. Code 2: Displays the 2nd part of the error buffer.

See also paragraph Error Codes for a description.

– 1.7. Options 1: Gives the option codes of option group

1 as set in SAM (Service Alignment Mode).

– 1.8. Options 2: Gives the option codes of option group

2 as set in SAM (Service Alignment Mode). – 1.13. 12NC SSB: Indication of the SSB order code. (*) – 1.13. Install date: This shall be filled in after time

extraction (triggered by disabling of virgin mode, so

first time customer does channel installation). Time

extraction is done via, teletext for Europe, PBS Public

Broadcast Channels for US. This, to determine exactly

the garanty period for call centers.

– 7.4. Tuned Bit: Indicates if the selected preset is

automatically tuned (via “Automatic Installation” in the setup menu) or via the automatic tuning system of the TV. In this case “Tuned bit” will show “YES”. If the TV was not able to auto-tune to the correct frequency, this item will show “NO”. So if “NO” is displayed, it could indicate that the customer has manually tuned to a frequency which was too far from a correct frequency, that the TV was not able to auto-tune any more.

– 7.6. Digital Signal Modulation: Indicates quality of

the received digital signal (0 = low).

• CSM 8: – 8.1. 12NC one zip SW: Displays the 12NC number of

the one-zip file as it is used for programming software in production. In this one-zip file all below software version can be found.

– 8.2. Initial Main SW: Displays the main software

version which was initially loaded by the factory.

– 8.3. Current Main SW: Displays the built-in main

software version. In case of field problems related to software, software can be upgraded. As this software is consumer upgradeable, it will also be published on the Internet. E.g. EJ30U_0.77.0.0.

– 8.5. Flash Utils SW: Displays the software version of

the software which contains all necessary components of the download application. To program this software, EJTAG tooling is needed.E.g. EJ30U_0.77.0.0.

– 8.6. Standby SW: Displays the built-in stand-by

processor software version. Upgrading this software will be possible via ComPair or via USB.(see chapter Software upgrade). E.g. STDBY_3.0.1.37.

software version. E.g. P3FW0_1.6.2.0

– 8.11. NVM version: Displays the NVM version as

programmed by factory. E.g. EJ30U_0.0.0.4

The abbreviations “SP” and “MP” in the figures stand for:

• SP: protection or error detected by the Stand-by Processor.

• MP: protection or error detected by the VIPER Main Processor.

How to Exit CSM

Press any key on the RC transmitter (with exception of the “CHANNEL +/-”, “VOLUME”, “MUTE” and digit (0-9) keys).

5.3 Stepwise Start-up

The stepwise start-up method, as known from FTL/FTP sets is not valid any more. The situation for this chassis is as follows: when the TV is in a protection state detected via the Stand-by Processor (and thus blinking an error) and SDM is activated via short cutting the pins on the SSB, the TV starts up until it reaches the situation just before protection. So, this is a kind of automatic stepwise start-up. In combination with the start-up diagrams below, you can see which supplies are present at a certain moment. Important to know here is, that if e.g. the 3V3 detection fails (and thus error 11 is blinking) and the TV is restarted via SDM, the Stand-by Processor will enable the 3V3, but will not go to protection now. The TV will stay in this situation until it is reset (Mains/AC Power supply interrupted).
