How to Activate SDM [Service Default Mode]
To activate SDM, use the following methods:
• Press the following key sequence on the RC transmitter:
“062596”, directly followed by the “Home” button. After activating this mode, “SDM” will appear in the upper
left corner of the screen.
How to Exit SDM
• Switch the set to Stand-by by pressing the standby button
on the remote control transmitter or on the television set.
• Via a standard customer RC-transmitter: key in
“00”-sequence.
Note: If the TV is switched “off” by a power interrupt
while in SDM, the TV will show up in the last status of SDM menu as soon as the
power is supplied again. The error buffer will not be cleared.
How to Activate SAM [Service Alignment Mode]
To activate SAM, use one of the following methods:
• Press the following key sequence on the remote control
transmitter: “062596”, directly followed by the “INFO” button. Do not allow the
display to time out between entries while keying the sequence.
• Or via ComPair.
After entering SAM, the following items are displayed,
with “SAM” in the upper right corner of the screen to indicate that the
television is in Service Alignment Mode
How to Store SAM Settings
To store the settings changed in SAM mode (except the RGB
Align settings), leave the top level SAM menu by using the POWER button on the
remote control transmitter or the television set. The mentioned exceptions must
be stored separately via the STORE button.
How to Exit SAM
Use one of the following methods:
• Switch the set to STANDBY by pressing the mains button on
the remote control transmitter or the television set.
• Via a standard RC-transmitter, key in “00” sequence.
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
Additionally, the entire error buffer is displayed when
Service Mode “SDM” is entered.
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 or via ComPair). 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/SDM/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).
Option Settings
The microprocessor communicates with a large number of I2C
ICs in the set. To ensure good communication and to make digital diagnosis
possible, the microprocessor has to know which ICs to address. The presence /
absence of these MT5366 ICs is made known by the option codes.
After changing the option(s), save them by pressing the OK
button on the RC before the cursor is moved to the left, select STORE and press
OK on the RC.
The new option setting is only active after the TV is
switched “off” / “stand-by” and “on” again with the mains switch (the NVM is
then read again).
Option Code Overview
Enter SAM mode to check the option codes. They could not be
edited in the NVM.
Display Code Overview
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 Table. After
resetting the Display Code, restart the set immediately.

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
“NVMeditor” 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 ComPair (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.
SSB Indentification
SSB’s of this chassis are identified by a “715” code on the
SSB. 715Axxxx-Nnn-MMM-OOOO
• 715 main category, Printed Wiring Board
• Axxxxsub 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 board.
