not be cleared.
Factory mode overview
Customer Service Mode (CSM)
The Customer Service Mode
shows error codes and information on the TVs 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.
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. use the Right/Left keys to display
the next/previous menu items
Note: Activation of the CSM is only possible if there is no (user) menu
on the screen.

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.
Then a window jumps out as below.
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.
Rename the file to “autorun.upg”
2. Prepare a USB memory.
3. Copy the software to USB flash disk(root directory).
4. Switch on 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 the version of this F/W before you change the software file name.
Step 3: Check the SW version
1.
After burning software, TV will restart
2. Press “123654”, enter Customer service mode to check if the software version is
correct.
Caution: Please make sure that software upgrade is finished before unplug the
USB and AC power.
Error Code
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 following 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).
Error codes overview
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:
• 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.
Diversity
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 backlight:
- 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.
DC/DC Converters
The
on-board DC/DC converters deliver the following voltages(depending on set
execution):
• +5V-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
• +1V8, voltage for EMMC when TV on
• TUNER_3V3, supply voltage for tuner
• +5V-SW, input intermediate supply voltage for USB Power
• +12V-AUDIO1 for the AUDIO AMP
+1.2V_DEMOD voltage for Demodulator IC channel decoder
• +3V3SBI,voltage for WIFI
