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:

• 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.
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
