PHILIPS 32PFL3406D Service mode troubleshooting tips and software update
PHILIPS 32PFL3406D
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).
• The possibility to overrule software protections when SDM is entered via the Service pins.
• Make alignments (e.g. White Tone), (de)select options, enter options codes, 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 uP (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).

Service
Default Mode (SDM)
How
to Activate
To activate analogue SDM, use one of the following methods:
• Press the following key sequence on the RC transmitter: “062596” directly followed by the MENU button.
• Short one of the “Service” pads on the TV board during cold start .Then press the mains button (remove the short after start-up).
Caution: When doing this, the service-technician must know exactly what he is doing, as it could damage the television set.

• Press the following sequence on the RC transmitter: “062593” directly followed by the MENU button.
• Press the following sequence on the RC transmitter: “062593” directly followed by the MENU button.
How
to Exit
Switch the set to Stand-by by
• pressing the standby button on the remote control transmitter or on the television set, or
• via a standard RC-transmitter by keying the “00” sequence.
If you switch the television set “off” by removing the mains (i.e., unplugging the television), the television set will remain in SDM when mains is re-applied, and the error buffer is not cleared. The error buffer will only be cleared when the “clear” command is used in the SAM menu.

Customer
Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and information on the TV’s operation settings. A call centre can instruct the customer (by telephone) to enter CSM in order to identify the status of the set. This helps them to diagnose problems and failures in the TV before making a service call. The CSM is a read-only mode; therefore, modifications are not possible in this mode.

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.

Troubleshooting
tips
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. HDMI CEC Not Functioning
Go to Home/Menu ->Setup -> Installation -> Preference and set the Easylink option to “on”. Also check if the connected device is CEC enabled.
TV Will Not Start-up from Stand-by.
Possible Stand-by Controller failure. Reflash the SW.
Repair Policy TCON Boards
Thriller sets (xxPFL3x06D/xx) in the 40" range have an additional “Philips” TCON board (diagram T01). This board should be swapped separately from the bare LCD panel. Alignment can be done using ComPair. All other TCON boards come with the LCD panel and should be swapped together as one entity.
Software Upgrading
Introduction
It is possible for the user to upgrade the main software via the USB port. This allows replacement of a software image in a stand alone set. A description on how to upgrade the main software can be found in the DFU or on the Philips website.
Main Software Upgrade
Automatic Software Upgrade
In “normal” conditions, so when there is no major problem with the TV, the main software and the default software upgrade application can be upgraded with the “autorun.upg” (FUS part in the one zip file). This can also be done by the consumers
themselves, but they will have to get their software from the commercial Philips website or via the Software Update Assistant in the user menu (see DFU). The “autorun.upg” file must be placed in the root of your USB stick.
How to upgrade:
1. Copy the “autorun.upg” file to the root of an USB stick.
2. Insert the USB stick in the side I/O while the set is “on”. The TV will prompt an upgrade message. Press “Update” to continue, after which the upgrading process will start. As soon as the programming is finished, the set must be restarted.
In the “Setup” menu you can check if the latest software is running.
How to Copy NVM Data to/from USB
Write NVM Data to USB
1. Insert the USB stick into the USB slot while in SAM mode.
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. HDMI CEC Not Functioning
Go to Home/Menu ->Setup -> Installation -> Preference and set the Easylink option to “on”. Also check if the connected device is CEC enabled.
