PHILIPS 42PFL4506H SERVICE MODE ERROR CODES

PHILIPS 42PFL4506


SERVICE MODE ERROR CODES 

Service Modes
The Service Mode feature is split into four parts:
• Service Default Mode (SDM).
• Service Alignment Mode (SAM).
• Customer Service Mode (CSM).
• Computer Aided Repair Mode (ComPair).
SDM and SAM offer features, which can be used by the Service engineer to repair/align a TV set. Some features are:
• A pre-defined situation to ensure measurements can be made under uniform conditions (SDM).
• Activates the blinking LED procedure for error identification when no picture is available (SDM).
• Make alignments (e.g. White Tone), reset the error buffer (SAM).
• Display information (“SDM” or “SAM” indication in upper right corner of screen, error buffer, software version, operating hours, options and option codes, sub menus).
The CSM is a Service Mode that can be enabled by the consumer. The CSM displays diagnosis information, which the customer can forward to the dealer or call centre. In CSM mode, “CSM”, is displayed in the top right corner of the screen.
The information provided in CSM and the purpose of CSM is to:
• Increase the home repair hit rate.
• Decrease the number of nuisance calls.
• Solved customers’ problem without home visit. ComPair Mode is used for communication between a computer and a TV on I2C /UART level and can be used by a Service engineer to quickly diagnose the TV set by reading out error codes, read and write in NVMs, communicate with ICs and the micro controller (PWM, registers, etc.), and by making use of a fault finding database. It will also be possible to up and download the software of the TV set via I2C with help of ComPair. To do this, ComPair has to be connected to the TV set via the compare connector, which will be accessible through the rear of the set (without removing the rear cover).
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).
General
Next items are applicable to all Service Modes or are general.
Life Timer
During the life time cycle of the TV set, a timer is kept (called “Op. Hour”). It counts the normal operation hours (not the Stand-by hours). The actual value of the timer is displayed in SDM and SAM in a decimal value. Every two soft-resets increase the hour by + 1. Stand-by hours are not counted.
Software Identification, Version, and Cluster
The software ID, version, and cluster will be shown in the main menu display of SDM, SAM, and CSM. The screen will show: “AAAAAB X.YY”, where:
• AAAAA is the chassis name.
• B is the region indication: E = Europe, A = AP/China, U = NAFTA, L = LATAM.
• X is the main version number: this is updated with a major change of specification (incompatible with the previous software version). Numbering will go from 01 - 99 and AA - ZZ.
- If the main version number changes, the new version number is written in the NVM.
- If the main version number changes, the default settings are loaded.
• YY is the sub version number: this is updated with a minor change (backwards compatible with the previous versions). Numbering will go from 00 - 99.
- If the sub version number changes, the new version number is written in the NVM.
- If the NVM is fresh, the software identification, version, and cluster will be written to NVM.
Display Option Code Selection
When after an SSB or display exchange, the display option code is not set properly, it will result in a TV with “no display”. Therefore, it is required to set this display option code after such a repair. To do so, press the following key sequence on a standard RC transmitter: “062598” directly followed by MENU and “xxx”, where “xxx” is a 3 digit decimal value of the panel type: see column “Display Code see sticker on the side/bottom of the cabinet. When the value is accepted and stored in NVM, the set will switch to Stand-by, to indicate that the process has been completed.
Service Default Mode (SDM)
Purpose
Set the TV in SDM mode in order to be able to create a predefined setting for measurements to be made. In this platform, a simplified SDM is introduced (without protection override and without tuning to a predefined frequency).
Specifications
• Set linear video and audio settings to 50%, but volume to 25%. Stored user settings are not affected.
• All service-unfriendly modes (if present) are disabled, since they interfere with diagnosing/repairing a set. These service unfriendly modes are:
– (Sleep) timer.
– Blue mute/Wall paper.
– Auto switch “off” (when there is no “input” signal).
– Hotel or hospital mode.
– Child lock or parental lock (manual or via V-chip).
– Skipping, blanking of “Not favourite”, “Skipped” or
“Locked” presets/channels.
– Automatic storing of Personal Preset or Last Status settings.
– Automatic user menu time-out (menu switches back/OFF automatically.
– Auto Volume levelling (AVL).
How to Activate SDM
To activate SDM, use the following methods:
Press the following key sequence on the RC transmitter: “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.
After activating this mode, “SDM” will appear in the upper left corner of the screen (when a picture is available).
On Screen Menu
After activating SDM, the following items are displayed, with “SDM” in the upper right corner of the screen to indicate that the television is in Service Default Mode. Menu items and explanation:
xxxxx Operating hours (in decimal).
AAAAAB X.YY See paragraph Software Identification, Version, and Cluster for the SW name definition.
ERR Shows all errors detected since the last time the buffer was erased in format <xxx> <xxx> <xxx> <xxx> <xxx> (five errors possible).
OP Used to read-out the option bytes. Ten codes (in two rows) are possible.
How to Navigate
As this mode is read only, there is not much to navigate. To switch to other modes, use one of the following methods:
• Command MENU from the user remote will enter the normal user menu (brightness, contrast, color, etc...) with “SDM” OSD remaining, and pressing MENU key again will return to the last status of SDM again.
• To prevent the OSD from interfering with measurements in SDM, command “OSD” or “i+” (“STATUS” or “INFO” for NAFTA and LATAM) from the user remote will toggle the OSD “on/off” with “SDM” OSD remaining always “on”.
• Press the following key sequence on the remote control transmitter: “062596” directly followed by the OK button to switch to SAM (do not allow the display to time out between entries while keying the sequence). Remarks: new RC will not have I+ button, but function still remains.
How to Exit SDM
• Switch the set to “Stand-by” by pressing the standby button on the remote control transmitter or on the television set.
• Via a standard customer RC-transmitter: key in “00”-sequence.
Note: If the TV is switched “off” by a power interrupt while in SDM, the TV will show up in the last status of SDM menu as soon as the power is supplied again. The error buffer will not be cleared.
Service Alignment Mode (SAM)
Purpose
• To modify the NVM.
• To display/clear the error code buffer.
• To perform alignments.
Specifications
• Operation hours counter (maximum five digits displayed).
• Software version, error codes, and option settings display.
• Error buffer clearing.
• Option settings.
• Software alignments (White Tone).
• NVM Editor.
• Set screen mode to full screen (all content is visible).
How to Activate SAM
To activate SAM, use one of the following methods:
Press the following key sequence on the remote control transmitter: “062596”, directly followed by the “OK” button. Do not allow the display to time out between entries while
keying the sequence.
• Or via ComPair. After entering SAM, the following items are displayed, with “SAM” in the upper right corner of the screen to indicate that the television is in Service Alignment Mode.
How to Navigate
• In the SAM menu, select menu items with the UP/DOWN keys on the remote control transmitter. The selected item will be indicated. When not all menu items fit on the screen, use the UP/DOWN keys to display the next/previous menu items.
• With the “LEFT/RIGHT” keys, it is possible to:
– (De) activate the selected menu item.
– (De) activate the selected sub menu.
– Change the value of the selected menu item.
• When you press the MENU button twice while in top level SAM, the set will switch to the normal user menu (with the SAM mode still active in the background). To return to the SAM menu press the MENU button.
• The “INFO [i+]” key from the user remote will toggle the OSD “on/off” with “SAM” OSD remaining always “on”.
• Press the following key sequence on the remote control transmitter: ì062596î directly followed by the MENU button to switch to SDM (do not allow the display to time out between entries while keying the sequence). Remarks: new RC will not have I+ button, but function still remain.
How to Store SAM Settings
To store the settings changed in SAM mode (except the RGB ALIGN settings), leave the top level SAM menu by using the POWER button on the remote control transmitter or the television set. The mentioned exceptions must be stored separately via the STORE button.
How to Exit SAM
Use one of the following methods:
• Switch the set to STANDBY by pressing the mains button on the remote control transmitter or the television set.
• Via a standard RC-transmitter, key in “00” sequence.
Note: When the TV is switched “off” by a power interrupt while in SAM, the TV will show up in “normal operation mode” as soon as the power is supplied again. The error buffer will not be cleared.
Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and information on the TV’s operation settings.The call centre can instruct the customer (by telephone) to enter CSM in order to identify the status of the set.This helps the call centre to diagnose problems and failures in the TV set before making a service call. The CSM is a read-only mode; therefore, modifications are not possible in this mode.
Specifications
• Ignore “Service unfriendly modes”.
• Line number for every line (to make CSM language independent).
• Set the screen mode to full screen (all contents on screen is visible).
• After leaving the Customer Service Mode, the original settings are restored.
• Possibility to use “CH+” or “CH-” for channel surfing, or enter the specific channel number on the RC.
How to Activate CSM
To activate CSM, press the following key sequence on a standard remote control transmitter: “123654” (do not allow the display to time out between entries while keying the sequence). 
After entering the Customer Service Mode, the following items are displayed.
Note: Activation of the CSM is only possible if there is no (user) menu on the screen.
Contents of CSM
1.1 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.
1.2 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.
1.3 Installation date Indicates the date of the first installation of the TV. This date is acquired via time extraction.
1.4 Option Code 1 Gives the option codes of option group 1 as set in SAM.
1.5 Option Code 2 Gives the option codes of option group 2 as set in SAM.
1.6 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. This identification number is the 12NC number of the SSB.
1.7 Display Displays the 12NC of the display.
1.8 PSU Displays the 12NC of the PSU.
2.1 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.
2.2 Standby SW Displays the built-in stand-by processor software version. Upgrading this software will be possible via USB.
2.3 Panel Code Displays the Display Code number.
2.4 NVM version Detects and displays NVM version.
3.1 Signal Quality/Present Analogue/digital signal strength.
3.2 Child lock Not active/active. This is a combined item for locks. If any lock (channel lock, parental lock) is active, the item shall show “active”.
3.3 HDCP keys Indicates if the HDMI keys (or HDCP keys) are valid or not. In case these keys are not valid and the customer wants to make use of the HDMI functionality, the SSB has to be replaced.
How to Navigate
By means of the “CURSOR-DOWN/UP” knob (or the scroll wheel) on the RC-transmitter, can be navigated through the menus.
How to Exit CSM
To exit CSM, use one of the following methods.
• Press the MENU/HOME button on the remote control transmitter.
• Press the POWER button on the remote control transmitter.
• Press the POWER button on the television set.
Error Codes
Introduction
Error codes are required to indicate failures in the TV set. In principle a unique error code is available for every.
• Activated (SW) protection.
• Failing I2C device.
• General I2C error.
The last five errors, stored in the NVM, are shown in the Service menu’s. This is called the error buffer. The error code buffer contains all errors detected since the last time the buffer was erased. The buffer is written from left to right. When an error occurs that is not yet in the error code buffer, it is displayed at the left side and all other errors shift one position to the right.
An error will be added to the buffer if this error differs from any error in the buffer. The last found error is displayed on the left. An error with a designated error code never leads to a deadlock situation. It must always be diagnosable (e.g. error buffer via OSD or blinking LED or via ComPair). In case a failure identified by an error code automatically results in other error codes (cause and effect), only the error code of the MAIN failure is displayed.
Errors code information:
How to Clear the Error Buffer
You can read the error buffer in three ways:
• On screen via the SAM/SDM/CSM (if you have a picture). Example:
ERROR: 0 0 0 0 0: No errors detected.
ERROR: 6 0 0 0 0: Error code 6 is the last and only detected error.
ERROR: 9 6 0 0 0: Error code 6 was detected first and error code 9 is the last detected (newest) error.
• Via the blinking LED procedure
Error codes
Errors code information:
Error 000: No problem.
Error 011: I2C bus error. When this error occurs, the TV will not start up due to the blocked bus.
Error 012: Tuner error. There is no I2C communication towards the tuner after start-up.
Error 013: Panel VCC error. This voltage is made in the power supply and results in protection in case of absence.
How to Clear the Error Buffer
The error code buffer is cleared in the following cases:
• By using the CLEAR command in the SAM menu.
• By using the following key sequence on the remote control transmitter: “062599” directly followed by the OK button.
• If the contents of the error buffer have not changed for 50 hours, the error buffer resets automatically.
Note: If you exit SAM by disconnecting the mains from the television set, the error buffer is not reset.
The Blinking LED Procedure
Introduction
The software is capable of identifying different kinds of errors. Because it is possible that more than one error can occur over time, an error buffer is available, which is capable of storing the last five errors that occurred. This is useful if the OSD is not working properly.
Errors can also be displayed by the blinking LED procedure. The method is to repeatedly let the front LED pulse with as many pulses as the error code number, followed by a period of
1.5 seconds in which the LED is “off”. Then this sequence is repeated.
Example (1): error code 4 will result in four times the sequence LED “on” for 0.25 seconds / LED “off” for 0.25 seconds. After this sequence, the LED will be “off” for 1.5 seconds. Any RC command terminates the sequence. Error code LED blinking is in red color.
Example (2): the content of the error buffer is “12 9 6 0 0” After entering SDM, the following occurs.
• 1 long blink of 5 seconds to start the sequence.
• 12 short blinks followed by a pause of 1.5 seconds.
• 9 short blinks followed by a pause of 1.5 seconds.
• 6 short blinks followed by a pause of 1.5 seconds.
• 1 long blink of 1.5 seconds to finish the sequence.
• The sequence starts again with 12 short blinks.
Displaying the Entire Error Buffer
Additionally, the entire error buffer is displayed when Service Mode “SDM” is entered.
Fault Finding and Repair Tips
Note:
• It is assumed that the components are mounted correctly with correct values and no bad solder joints.
• Before any fault finding actions, check if the correct options are set.
NVM Editor
In some cases, it can be convenient if one directly can change the NVM contents. This can be done with the “NVM Editor” in SAM mode. With this option, single bytes can be changed.
Caution:
• Do not change these, without understanding the function of each setting, because incorrect NVM settings may seriously hamper the correct functioning of the TV set!
• Always write down the existing NVM settings, before changing the settings. This will enable you to return to the original settings, if the new settings turn out to be incorrect.
Load Default NVM Values
It is possible to upload the default values to the NVM with ComPair in case the SW is changed, the NVM is replaced with a new (empty) one, or when the NVM content is corrupted. After replacing an EEPROM (or with a defective/no EEPROM), default settings should be used to enable the set to start-up and allow the Service Default Mode and Service Alignment Mode to be accessed.
No Picture
When you have no picture, first make sure you have entered the correct display code.
Unstable Picture via HDMI input
Check (via ComPair) if HDMI EDID data is properly programmed.
No Picture via HDMI input
Check if HDCP key is valid. This can be done in CSM.
TV Will Not Start-up from Stand-by
Possible Stand-by Controller failure. Re-flash the software.
CSM
When CSM is activated and there is a USB memory stick connected to the TV, the software will dump the complete CSM content to the USB memory stick. The file (Csm.txt) will be saved in the root of the USB memory stick.
Loudspeakers
Make sure that the volume is set to minimum during disconnecting the speakers in the ON-state of the TV. The audio amplifier can be damaged by disconnecting the speakers during ON-stat.
Display option code
Attention: In case the SSB is replaced, always check the Display Code in CSM, even when picture is available. Performance with the incorrect display option code can lead to unwanted side-effects for certain conditions.
Reset of Repaired SSB
A very important issue towards a repaired SSB from a Service repair shop (SSB repair on component level) implies the reset of the NVM on the SSB. A repaired SSB in Service should get the service Set type “00PF0000000000” and Production code “00000000000000”. Also the virgin bit has to be set. To set all this, you can use the ComPair tool or use the “NVM editor” and “Service Data” items in SAM (do not forget to “store”). After a repaired SSB has been mounted in the set (set repair on board level), the type number (CTN) and production code of the TV has to be set according to the type plate of the set. For this, you can use the NVM editor in SAM. Loading of the CTN and production code can also be done via ComPair (Model number programming).
In case of a display replacement, reset the “Operation hours display” to “0”, or to the operation hours of the replacement display.
