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.
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
-6
),
nano-farads (n= x10
-9
), or pico-farads (p= x10
-12
).
Capacitor values may also use the value multiplier as the decimal point indication (e.g. 2p2 indicates 2.2 pF).
An "asterisk" (*) indicates component usage varies. Refer to the diversity tables for the correct values.
The correct component values are listed in the Spare Parts List. Therefore, always check this list when there is any doubt.
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.
Directions for Use
EN 6 EJ3.0U PA3.
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.
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.
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 Exchanging a Defective PDP
If a PDP has defective or "dead" pixels, do the following:
1. Locate the defective pixels.
2. Indicate their positions by means of a marker (with erasable ink!).
3. Indicate the positions of the defective pixels in the Defects Description Form (DDF), which is published in the PDP manuals.
4. After this, remove the PDP and return it to your Service organization.
If a PDP has to be removed from the TV set, always keep in mind that the PDP parts can easily be damaged by ESD, so take the following protective measures:
Do not damage the flex foils (they are located on the left, right, upper and lower sides of the PDP).
Do not scratch the glass plate.
Avoid fingerprints.
2.3.7 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!
2.3.8 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.

5.9 Software Upgrading
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,
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”.

Service Modes, Error Codes, and Fault Finding
EN 13EJ3.0U PA 5.
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.
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.

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 11.3. 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
3.2. Dolby: Indicates whether the received transmitter
transmits Dolby sound (“ON”) or not (“OFF”). Attention: The presence of Dolby can only be tested by the software on the Dolby Signaling bit. If a Dolby transmission is received without a Dolby Signaling bit, this indicator will show “OFF” even though a Dolby transmission is received.
3.3. Surround Mode: Indicates the by the customer
selected sound mode (or automatically chosen mode). Possible values are “STEREO” and “VIRTUAL DOLBY SURROUND”. Change via “MENU”, “TV”, “SOUND”, “SOUND MODE”. It can also have been selected
automatically by signaling bits (internal software). – 3.4. Center Input: Not applicable. – 3.5. Audio System: Gives information about the
audible audio system. Possible values are “Stereo”,
”Mono”, “Mono selected”, “Analog In: No Dig. Audio”,
“Dolby Digital 1+1”, “Dolby Digital 1/0”, “Dolby Digital 2/
0”, “Dolby Digital 2/1”, “Dolby Digital 2/2”, “Dolby Digital
3/0”, “Dolby Digital 3/1”, “Dolby Digital 3/2”, “Dolby
Digital Dual I”, “Dolby Digital Dual II”, “MPEG 1+1”,
“MPEG 1/0”, “MPEG 2/0”. This is the same info as you
will see when pressing the “INFO” button in normal
user mode (item “signal”). In case of ATSC receiving
there will be no info displayed. – 3.6. AVL: Indicates the last status of AVL (Automatic
Volume Level): “ON” or “OFF”. Change via “MENU”,
“TV”, “SOUND”, “AVL”. AVL can not be set in case of
digital audio reception (e.g. Dolby Digital or AC3) – 3.7. Delta Volume: Indicates the last status of the
delta volume for the selected preset as set by the
customer: from “-12” to “+12”. Change via “MENU”,
“TV”, “SOUND”, “DELTA VOLUME”.
CSM 4:4.1. Preset Lock. Indicates if the selected preset has
a child lock: “LOCKED” or “UNLOCKED”. Change via “MENU”, “TV”, “CHANNELS”, “CHANNEL LOCK”.
4.3. Lock After: Indicates at what time the channel
lock is set: “OFF” or e.g. “18:45” (lock time). Change “MENU”, “TV”, “CHANNELS”, “LOCK AFTER”.
4.6. TV Ratings Lock: Indicates the “TV ratings lock”
as set by the customer. Change via “MENU”, “TV”,
Service Modes, Error Codes, and Fault Finding
EN 17EJ3.0U PA 5.
CSM 7:7.2. TV System: Gives information about the video
system of the selected transmitter. a. M: NTSC M signal received. b. ATSC: ATSC signal received.
7.3. Source: Indicates which source is used and the
video/audio signal quality of the selected source. (Example: Tuner, Video/NICAM) Source: “TUNER”, “AV1”, “AV2”, “AV3”, “HDMI 1”, “SIDE”. Video signal quality: “VIDEO”, “S-VIDEO”, “RGB 1FH”, “YPBPR 1FH 480P”, “YPBPR 1FH 576P”, “YPBPR 1FH 1080I”, “YPBPR 2FH 480P”, “YPBPR 2FH 576P”, “YPBPR 2FH 1080I”, “RGB 2FH 480P”, “RGB 2FH 576P” or “RGB 2FH 1080I”. Audio signal quality: “STEREO”, “SPDIF 1”, “SPDIF 2”, or “SPDIF”.
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.

8.11. NVM version: Displays the NVM version as
programmed by factory. E.g. EJ30U_0.0.0.4
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
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).
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.

If the protection state was left by short circuiting the
SDM pins, detection of a protection condition during
startup will stall the startup. Protection conditions in a
playing set will be ignored. The protection mode will
not be entered.
PDPGO line is high (either HW wise in a non FHP set or
because of the stby µP reset in a FHP set) which is the good
state at cold boot to be able to start the FHP.
Switching the POD-MODE low in an FHP PDP set makes the CPUGO go high and starts the PDP CPU.
PDPGO

Yes
Switching the POD-MODE and the ON-mode low in an SDI PDP set makes the PDP supplies go to th e ON mode.
Wait 50ms and then start polling the detect-
5V, detect-8V6 and detect-12V every 40ms.
The availability of the supplies is checked through detect signals (delivered by
dedicated detect-IC's) going to the st-by µP. These signals are available for
+12V, +8V6, +5V, +1V2 and +2V5. A low to high transition of the signals should
occur within a certain time after toggling the standby line. If an observers is
detected before the time-out elapses, of course, the process should continue in
order to minimize start up time.
Switch LOW the NVM power reset line. Add a 2ms delay before trying to address the NVM to allow correct NVM
initialization.
Audio Protection Line
HIGH?
No
Yes
Audio Er ror
SP
The audio protection circuit shuts down the supply autonomously. This triggers a set restart and during that restart (so at this check here), it will be observed that the audio protection line is high and the audio protection mode is entered. This condition is not valid for an SDI PDP. In this PDP set, the audio protection latch is not present and hence the HIGH condition here will never be observed. As a result, when an audio protection occurs, the set will restart and will enter a supply protection mode because of a missing power supply.

Switching on the power supply in an LPL scanning backlight set, also switches on the backlight supply. The display should not be used the first 5 seconds the backlight supply is running due to a pre-heat time of 4s and a 100% light output (not adjustable) the next second. This 5 second delay does not delay the startup of the display as this time is absorbed in the startup time of the rest of the system.

2. ComPair allows very detailed diagnostics and is therefore capable of accurately indicating problem areas. You do not have to know anything about I2C or UART commands yourself, because ComPair takes care of this.
3. ComPair speeds up the repair time since it can automatically communicate with the chassis (when the uP is working) and all repair information is directly available.
4. ComPair features TV software up possibilities.
Specifications
ComPair consists of a Windows based fault finding program and an interface box between PC and the (defective) product. The (new) 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.
5.4.2 LVDS Tool
Introduction
This Service tool (also called “ComPair Assistant 1“) may help you to identify, in case the TV does not show any picture, whether the Small Signal Board (SSB) or the display of a Flat TV is defective. Thus to determine if LVDS, RGB, and sync signals are okay.
When operating, the tool will show a small (scaled) picture on a VGA monitor. Due to a limited memory capacity, it is not possible to increase the size when processing high-resolution LVDS signals (> 1280x960). Below this resolution, or when a DVI monitor is used, the displayed picture will be full size.
How to Connect
Connections are explained in the user manual, which is packed with the tool. The LVDS cables included in the package cover most chassis. For some chassis, a separate cable must be ordered.
Note: To use the LVDS tool, you must have ComPair release 2004-1 (or later) on your PC (engine version >= 2.2.05). For every TV type number and screen size, one must choose the proper settings via ComPair. The ComPair file will be updated regularly with new introduced chassis information.

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 has occurred, the error is added to the list of errors, provided the list is not full or the error is a protection error. 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), except when the error is a protection error. To prevent that an occasional error stays in the list forever, the error is removed from the list after 50+ operation hours. When multiple errors occur (errors occurred within a short time span), there is a high probability that there is some relation between them.
Basically there are three kinds of errors:
Errors detected by the Stand-by Processor. These errors will always lead to protection and an automatic start of the blinking LED for the concerned error (see paragraph “The Blinking LED Procedure”). In these cases SDM can be used to start up (see chapter “Stepwise Start-up”).
Errors detected by VIPER that lead to protection. In this case the TV will go to protection and the front LED will blink at 3 Hz. Further diagnosis via service modes is not possible here (see also paragraph “Error Codes” -> “Error Buffer” ­> “Extra Info”).
Errors detected by VIPER that do not lead to protection. In this case the error can be read out via ComPair, via the blinking LED method, or in case you have picture, via SAM.
5.5.2 How to Read the Error Buffer
Use one of the following methods:
On screen via the SAM (only if you have a picture). E.g.: – 00 00 00 00 00: No errors detected – 06 00 00 00 00: Error code 6 is the last and only
detected error
09 06 00 00 00: Error code 6 was first detected and
error code 9 is the last detected error
Via the blinking LED procedure (when you have no picture). See next paragraph.
•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.
With a normal RC, key in sequence “MUTE” followed by “062599” and “OK”.
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 you begin the repair (before clearing the buffer, write down the content, as this history can give you significant information). This to ensure that old error codes are no longer present. 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 stand-by processor.
Via sensing of analogue values on the stand-by processor.
Via a “not acknowledge” of an I
2
C communication
Take notice that some errors need more than 90 seconds before they start blinking. So in case of problems wait 2 minutes from start-up onwards, and then check if the front LED

Extra Info
Error 1 (I
2
C bus 1 blocked). When this error occurs, the TV will go to protection and the front LED will blink at 3 Hz. Now you can partially restart the TV via the SDM shortcut pins on the SSB. Depending on the software version it is possible that no further diagnose (error code read-out) is possible. With the knowledge that only errors 1, 2, 4, and 63 result in a 3 Hz blinking LED, the range of possible defects is limited.
Error 2 (I
2
C bus 2 blocked). When this error occurs, the TV will go to protection and the front LED will blink at 3 Hz. Now you can partially restart the TV via the SDM shortcut pins on the SSB. Due to hardware restriction (I
2
C bus 2 is
the fast I
2
C bus) it will be impossible to start up the VIPER and therefore it is also impossible to read out the error codes via ComPair or via the blinking LED method. With the knowledge that only errors 1, 2, 4, and 63 result in a 3 Hz blinking LED, the range of possible defects is limited. When you have restarted the TV via the SDM shortcut pins, and then pressed "CH+" on your remote control, the TV will go to protection again, and the front LED blink at 3 Hz again. This could be an indication that the problem is related to error 2.
Error 3 (I
2
C bus 3 blocked). There are only three devices
on I
2
C bus 3: VIPER, Stand-by Processor, and NVM. The Stand-by Processor is the detection device of this error, so this error will only occur if the VIPER or the NVM is blocking the bus. This error will also be logged when the NVM gives no acknowledge on the I
2
C bus (see error 44). Note that if the 12 V supply is missing (connector 1M46 on the SSB), the DC/DC supply on the SSB will not work. Therefore the VIPER will not get supplies and could block I
2
C bus 3. So,
a missing 12 V can also lead to an error 3.
Error 4 (I
2
C bus 4 blocked). Error 4 is displayed in SAM.
No protection.
Error 5 (Viper doesn’t boot). This error will point to a severe hardware problem around the VIPER (supplies not OK, VIPER completely dead, I
2
C link between VIPER and
Stand-by Processor broken, etc. ...).
Error 7 (8.6 V error). Except a physical problem with the
8.6 V itself, it is also possible that there is something wrong with the Audio DC Protection: see paragraph "Hardware Protections" for this.
Error 12 (12 V error). Except a physical problem with the
Error 44 (NVM). This error will never occur because it is masked by error 3 (I
2
C bus 3). The detection mechanism
for error 3 checks on an I
2
C acknowledge of the NVM. If NVM gives no acknowledge, the stand-by software assumes that the bus is blocked, the TV goes to protection and error 3 will be blinking.
Error 53. This error will indicate that the VIPER has started to function (by reading his boot script, if this would have failed, error 5 would blink) but initialization was never completed because of hardware peripheral problems (NAND flash, ...) or software initialization problems. Possible cause could be that there is no valid software loaded (try to upgrade to the latest main software version).
5.6 The Blinking LED Procedure
5.6.1 Introduction
The blinking LED procedure can be split up into two situations:
Blinking LED procedure in case of a protection detected by the stand-by processor. In this case the error is automatically blinked. This will be only one error, namely the one that is causing the protection. Therefore, you do not have to do anything special, just read out the blinks. A long blink indicates the decimal digit, a short blink indicates the units.
Blinking LED procedure in the “ON” state. Via this procedure, you can make the contents of the error buffer visible via the front LED. This is especially useful for fault finding, when there is no picture.
When the blinking LED procedure is activated in the “ON” state, the front LED will show (blink) the contents of the error-buffer. Error-codes > 10 are shown as follows:
1. “n” long blinks (where “n” = 1 - 9) indicating decimal digit,
2. A pause of 1.5 s,
3. “n” short blinks (where “n”= 1 - 9),
4. A pause of approx. 3 s.
5. When all the error-codes are displayed, the sequence finishes with a LED blink of 3 s,
6. The sequence starts again.

5.7 Protections
5.7.1 Software Protections
Most of the protections and errors use either the stand-by microprocessor or the VIPER controller as detection device. Since in these cases, checking of observers, polling of ADCs, filtering of input values are all heavily software based, these protections are referred to as software protections. There are several types of software related protections, solving a variety of fault conditions:
Protections related to supplies: check of the 12V, +5V, +8V6, +1.2V, +2.5V and +3.3V.
Protections related to breakdown of the safety check mechanism. E.g. since a lot of protection detections are done by means of the VIPER, failing of the VIPER communication will have to initiate a protection mode since safety cannot be guaranteed anymore.
Remark on the Supply Errors
The detection of a supply dip or supply loss during the normal playing of the set does not lead to a protection, but to a cold reboot of the set.
Protections during Start-up
During TV start-up, some voltages and IC observers are actively monitored to be able to optimize the start-up speed, and to assure good operation of all components. If these monitors do not respond in a defined way, this indicates a malfunction of the system and leads to a protection. As the observers are only used during start-up, they are described in the start-up flow in detail (see paragraph “Stepwise Start-up").
5.7.2 Hardware Protections
There is one hardware protection in this chassis: “Audio DC Protection”. This protection occurs when there is a DC voltage on the speakers. In that case the main supply is switched "OFF", but the stand-by supply is still working.
Repair Tip
It is also possible that you have an audio DC protection
5.8.4 DC/DC Converter
Introduction
The best way to find a failure in the DC/DC converters is to check their starting-up sequence at power "ON" via the Mains/AC Power cord, presuming that the Stand-by Processor is operational.
If the input voltage of the DC/DC converters is around 12 V (measured on the decoupling capacitors 2U17/2U25/ 2U45) and the ENABLE signals are "low" (active), then the output voltages should have their normal values.
First, the Stand-by Processor activates the +1V2 supply (via ENABLE-1V2).
Then, after this voltage becomes present and is detected OK (about 100 ms), the other two voltages (+2V5 and +3V3) will be activated (via ENABLE-3V3).
The current consumption of controller IC 7U00 is around 20 mA (that means around 200 mV voltage drop across resistor 3U22).
The current capability of DC/DC converters is quite high (short-circuit current is 7 to 10 A), therefore if there is a linear integrated stabilizer that, for example delivers 1.8V from +3V3 with its output overloaded, the +3V3 stays usually at its normal value even though the consumption from +3V3 increases significantly.
The +2V5 supply voltage is obtained via a linear stabilizer made with discrete components that can deliver a lot of current. Therefore, in case +2V5 (or +2V5D) is short­circuited to GND, the +3V3 will not have the normal value but much less.
The supply voltage +12VSW is protected for over-currents by fuse 1U04.
Fault Finding
Symptom: +1V2, +2V5, and +3V3 not present (even for a short while ~10ms).
1. Check 12V availability (fuse 1U01, resistor 3U22,
power MOSFETs) and enable signal ENABLE-1V2 (active low).
2. Check the voltage on pin 9 (1.5 V).
3. Check for +1V2 output voltage short-circuit to GND that
can generate pulsed over-currents 7-10 A through coil 5U03.
Service Modes, Error Codes, and Fault Finding
EN 29EJ3.0U PA 5.
Cause: Instability of the frequency and/or duty cycle of one
or both DC/DC converters. – Check resistor 3U06, the decoupling capacitors, the
AC feedback circuits (2U20 + 2U21 + 3U14 + 3U15 for +1V2 or 2U19 + 2U85 + 3U12 + 3U13 for +3V3), the compensation capacitors 2U09, 2U10, 2U23 and 2U73, and IC 7U00.
Note 1: If fuse 1U01 is broken, this usually means a pair of defective power MOSFETs (7U01 or 7U03). Item 7U00 should be replaced as well in this case.
5.9 Software Upgrading
5.9.1 Introduction
The set software and security keys are stored in a NAND-Flash (item 7P80), which is connected to the VIPER via the PCI bus.
It is possible for the user to upgrade the main software via the USB port. This allows replacement of a software image in a standalone set, without the need of an E-JTAG debugger. A description on how to upgrade the main software can be found in the "Directions For Use".
Important: When the NAND-Flash must be replaced, a new SSB must be ordered, due to the presence of the security keys!!! See table “SSB service kits” for the order codes. Perform the following actions after SSB replacement:
1. Set the correct option codes (see sticker inside the TV).
2. Update the TV software (see chapter 3 for instructions).
3. Perform the alignments as described in chapter 8.
4. Check in CSM menu 5 if the HDMI key is valid.
Table 5-4 SSB service kits (for EJ3.0U LA chassis)
Note: After replacing the SSB, execute the alignments
according to the instructions in this manual.
Partition 1 (Customer)
To do a main software upgrade (partition 1) via USB, the set must be operational, and the "Partition 0" files for the VIPER must be installed in the NAND-Flash!
The new software can be uploaded to the TV by using a portable memory device or USB storage compliant devices (e.g. USB memory stick). You can download the new software from the Philips website to your PC.
Partition 0 (Service)
If the "Partition 0" software is corrupted, the software needs to be re-installed. To upgrade this “USB download application” (partition 0 except the bootblock), insert an USB stick with the correct software, but press the “red” button on the remote control (in ”TV” mode) when it is asked via the on screen text.
Caution:
The USB download application will now erase both partitions (except the boot block), so you need to reload the main SW after upgrading the USB download application. As long as this is not done, the USB download application will start when the set is switched “ON”.
When something goes wrong during the progress of this method (e.g. voltage dip or corrupted software file), the set will not start up, and can only be recovered via the EJTAG tool!
5.9.3 Manual Start of the Main Software Upgrade Application
Normally, the software upgrading procedure will start automatically, when a memory device with the correct software is inserted, but in case this does not work, it is possible to force the TV into the software upgrade application. To do so:
Disconnect the TV from the Mains/AC Power.
Press the “OK” button on a Philips DVD RC-6 remote control (it is also possible to use the TV remote in "DVD" mode).
Keep the “OK” button pressed while connecting the TV to the Mains/AC Power.
The software upgrade application will start.
When a memory device with upgrade software is
