Service Modes
The Service Mode feature is split into following parts:
Service Alignment Mode (SAM).
Factory Mode.
Customer Service Mode (CSM).

SAM and the Factory mode offer features, which can be used by the Service engineer to repair/align a TV set. Some features are:
Make alignments (e.g. White Tone), reset the error buffer(SAM and Factory Mode).
Display information (“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.
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).
Service Alignment Mode (SAM)

Software Upgrading, Error code and Panel Code
Software Upgrading.
The following update is for .pkg file.
1. Rename the file to “upgrade_loader.pkg”
2. Prepare a USB memory.
3. Copy the software to USB flash disk(root directory).
4. Switch off the TV and Insert the USB memory stick that contains the software update files in one of the TV’s USB 2.0 ports.
Note: It contains USB3.0 port, if connect on it, the software may can’t be detected.
5. Switch on the TV. The TV will detect the USB memory s tick automatically.

6. When the TV software is updated, the TV will turn on again automatically. Remove your USB flash drive.
7. We can enter in CSM or Factory mode to check the current software version.
The following update is for .upg file.
Step 1: Ready for F/W Upgrade
1. Prepare a USB memory.
2. Copy the software to USB flash disk(root directory).
Note the version of this F/W before you change the software file name.

Step 2: F/W Upgrade

2. Press “Menu+1999+back”, enter Factory mode to check if the software version is correct
Caution: Make sure that software upgrade is finished before unplug the USB and AC power!

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).
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.
How to Read the Error Buffer
You can read the error buffer in three ways:
• On screen via the SAM/CSM (if you have a picture).
Example:
– ERROR: 000 000 000 000 000: No errors detected
– ERROR: 013 000 000 000 000: Error code 13 is the last and only detected error
– ERROR: 034 013 000 000 000: Error code 13 was detected first and error code 34 is the last detected (newest) error
• Via the blinking LED procedure (when you have no picture)

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.
Panel Code.
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” in below tab. After resetting the Display Code, restart the set immediately.

Power Supply Unit.
All power supplies are a black box for Service. When defective, a new board must be ordered and the defective one must be returned, unless the main fuse
of the board is 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.
Important delta’s with the platform are:
• New power architecture for LED backlight
• “Boost”-signal is now a PWM-signal + continuous variable
The control signals are:
• PS-ON
• Lamp “on/off”
• DIM (PWM) (not for PSDL)
In this manual, no detailed information is available because of design protection issues.
• +8.5V output (standby mode)
• +12 output (on-mode)
• +12V_audio (audio AMP power)
• 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.

DC/DC Converters.
The on-board DC/DC converters deliver the following voltages(depending on set execution):
• +3V3-SB, permanent voltage for the Stand-by Power system
• +3V3-STANDBY,voltage for IR/Key board
• +12V, input from the power supply for the panel common(active mode)
• 12V, input from the power supply for LNB supply
• +3V3-EMMC, voltage for EMMC when TV on
