32PFL3406-98 – Philips Ebony LCD TV – Service mode, adjustments procedure, Power Board schematic

If a board is defective, consult your repair personal to decide if the board has to be exchanged or if it should be repaired on component level.  If your service technician 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.

Service Modes, Error Codes

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)

Service Default Mode (SDM)

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).

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, colour, 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”.

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.

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: “062596” 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.

Blind SAM 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” below:

When the value is accepted and stored in NVM, the set will switch to Stand-by, to indicate that the process has been completed.
During this algorithm, the NVM-content must be filtered, because several items in the NVM are TV-related and not SSB related (e.g. Model and Prod. S/N). Therefore, “Model” and “Prod. S/N” data is changed into “See Type Plate”. In case a call centre or consumer reads “See Type Plate” in CSM mode, he needs to look to the side/bottom sticker to identify the set, for further actions.

Error Codes

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:
• 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

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 (when you have no picture)

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 BuffeThe 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

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

Additionally, the entire error buffer is displayed when Service Mode “SDM” is entered.

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.

• 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.

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 (MENU > Setup > TV settings > Reinstall TV > Start now) is 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. The loading of the CTN and production code can also be done via compare (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.

SSB (Small Signal Board)

Power Supply Unit
Before checking other parts first check whether fuse on the PSU is not broken. Always replace a defective fuse with one with the correct specifications. This part is available in the regular market.
Consult the Philips Service web portal for the order codes of the boards.

The output voltages to the chassis are:
• +5V-STANDBY (Stand-by mode only)
• +12V (on-mode)
• +18V for audio circuit

The diversity in power supply units is mainly determined by the diversity in screen sizes, but please note to always order the correct replacement.

The on-board DC/DC converters deliver the following voltages (depending on set execution):
• +5V-STANDBY, permanent voltage for the Stand-by controller, LED/IR receiver and controls; connector CN701 pin 11 and 12.
• +12V, input from the power supply for panel and tuner; connector CN701 pins 3 and 4.
• +24V, input from the power supply for audio (in active mode); connector CN701 pins 8 and 9
