PHILIPS 32PFL3008D – 39PFL3008D – 42PFL3008D – 46PFL300D – BLINKING CODES - FACTORY MODE - and OTHER DETAILS

 

FACTORY MODE

How to Activate the Factory mode
To activate the Factory mode, use the following method:
* Press the following key sequence on the remote control transmitter: from the “Home screen” press “1999”, directly followed by the “Back” button. Do not allow the display to time out between entries while keying the sequence.

How to Exit the Factory mode
Use one of the following methods:
* Select EXIT_FACTORY from the menu and press the “OK” button.
Note: When the TV is switched “off” by a power interrupt, or normal switch to “stand-by” while in the factory mode, the TV will show up in “normal operation mode” as soon as the power is supplied again. The error buffer will not be cleared.

Error codes

In this chassis only “layer 2” error codes are available and point to problems on the SSB. They are triggered by LED blinking when CSM is activated. Only the following layer 2 errors are defined:

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 CLEAR command in the Factory mode:
* 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.

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.

Unstable Picture via HDMI input

Check (via ComPair or factory mode) 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 Do Not Start-up from Stand-by

Possible Stand-by Controller failure. Re-flash the software.

Audio Amplifier

The Class D-IC U606 has a power pad for cooling. When the IC is replaced it must be ensured that the power pad is very well pushed to the PWB while the solder is still liquid. This is needed to insure that the cooling is guaranteed, otherwise the Class D-IC could break down in short time.

CSM [Customer Service Mode]

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-state of the set.

Display option code

Attention: In case the SSB is replaced, always check the Panel Code in CSM, even when picture is available. Performance with the incorrect display option code can lead to unwanted side-effects for certain conditions.

SSB [Small Sognal Board] Identification

SSB’s of this chassis are identified by a “715” code on the SSB. 715Axxxx-Nnn-MMM-OOOO
> 15 main category, Printed Wiring Board
> Axxxx sub category, sequential coding number
> Nnn Version code
> N Development number
> nn Production number
> MMM Mounting variation code
> OOOO Optional variation code
Make sure when replacing an SSB the SSB identification codes match the replacement panel.

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 is to be set. To set all this, you can use the ComPair tool or use the “NVM editor” and “Dealer options” 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.
Remark:
# After the NVM has been replaced, go to SAM and scroll to the <Reload MAC address>
# Select the item and press <OK> on the RC.

Power Supply Unit

All power supplies are a black box for Service. When defective, a new panel must be ordered and the defective one must be returned, unless the main fuse of the panel is broken. Always replace a defective fuse with one with the correct specifications.

Important delta’s with the TPS10.L LA classis platform are:
* New power architecture for LED backlight
* “Boost”-signal is now a PWM-signal + continuous variable.

The control signals are:
* Stand-by
* Inverter “on/off”
* DIM (PWM) (not for PSDL)

The output voltages to the chassis are:
* +4V7-STANDBY (Stand-by mode only)
* +12V (on-mode)
* +Vsnd (+24V) (audio power) (on-mode)
* +24V (bolt-on power) (on-mode)
* Output to the display; in case of
> IPB: High voltage to the LCD panel
> PSL and PSLS (LED-driver outputs)
> PSDL (high frequent) AC-current.

The diversity in power supply units is mainly determined by the diversity in displays.

The following displays can be distinguished:
* CCFL/EEFL backlight: power panel is conventional IPB
* LED back-light:
> side-view LED without scanning: PSL power panel
> side-view LED with scanning: PSLS power panel
> direct-view LED without 2D-dimming: PSL power panel
> direct-view LED with 2D-dimming: PSDL power panel.

PSL stands for Power Supply with integrated LED-drivers.
PSLS stands for a Power Supply with integrated LED-drivers with added Scanning functionality (added microcontroller).
PSDL stands for a Power Supply for Direct-view LED backlight with 2D-dimming.
