How to Activate SDM
For this chassis there are two kinds of SDM: an analog SDM and a digital SDM. Tuning will happen according.
Analog SDM: use the standard RC-transmitter and key in the code “062596”, directly followed by the “MENU” (or HOME) button.
Note: It is possible that, together with the SDM, the main menu will appear. To switch it “off”, push the “MENU”(or HOME) button again.
Digital SDM: use the standard RC-transmitter and key in the code “062593”, directly followed by the “MENU” (or HOME) button.Note: It is possible that, together with the SDM, the main menu will appear. To switch it “off”, push the “MENU” (or HOME) button again.
Analog SDM can also be activated by grounding for a moment the solder pad on the SSB, with the indication “SDM” (
see Service mode pad). Service mode pad
After activating this mode, “SDM” will appear in the upper right corner of the screen (when a picture is available).

How to Navigate
When the “MENU” (or HOME) button is pressed on the RC transmitter, the TV set will toggle between the SDM and the normal user menu.
How to Exit SDM
Use one of the following methods:
# Switch the set to STAND-BY via the RC-transmitter.
# Via a standard customer RC-transmitter: key in “00”- After activating this mode, “SDM” will appear in the upper right corner of the screen (when a picture is available).
Service Alignment Mode (SAM)
Purpose
# To perform (software) alignments.
# To change option settings.
# To easily identify the used software version.
# To view operation hours.
# To display (or clear) the error code buffer.
How to Activate SAM
Via a standard RC transmitter: Key in the code “062596” directly followed by the “INFO” button. After activating SAM with this method a service warning will appear on the screen, continue by pressing the “OK” button on the RC.
How to Navigate
# In SAM, the menu items can be selected with the
“CURSOR UP/DOWN” key on the RC-transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the “CURSOR UP/DOWN” key to display the next/previous menu items.
# With the “CURSOR LEFT/RIGHT” keys, it is possible to:
# (De) activate the selected menu item.
# (De) activate the selected sub menu.
# With the “OK” key, it is possible to activate the selected action.
How to Exit SAM
Use one of the following methods:
# Switch the TV set to STAND-BY via the RC-transmitter.
# Via a standard RC-transmitter, key in “00” sequence, or select the “BACK” key.
CSM
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.
NoteActivation of the CSM is only possible if there is no (user) menu on the screen!
How to Navigate
By means of the “CURSOR-DOWN/UP” knob on the RCtransmitter, can be navigated through the menus.
How to Exit CSM
Press “MENU” (or HOME) / “Back” key on the RC-transmitter.
The Blinking LED Procedure
The blinking LED procedure can be split up into two situations:
# Blinking LED procedure LAYER 1 error. In this case the error is automatically blinked when the TV is put in CSM. This will be only one digit error, namely the one that is referring to the defective board which causes the failure of the TV. This approach will especially be used for home repair and call centres. The aim here is to have service diagnosis from a distance.
# Blinking LED procedure LAYER 2 error. Via this procedure, the contents of the error buffer can be made visible via the front LED. In this case the error contains 2 digits and will be displayed when SDM (hardware pins) is activated. This is especially useful for fault finding and gives more details regarding the failure of the defective board.
Important remark:
For all errors detected by MIPS which are fatal => rebooting of the TV set (reboot starts after LAYER 1 error blinking), one should short the solder paths at start-up from the power OFF state by mains interruption and not via the power button to trigger the SDM via the hardware pins.
When one of the blinking LED procedures is activated, the front LED will show (blink) the contents of the error buffer. Error codes greater then 10 are shown as follows:
1. “n” long blinks (where “n” = 1 to 9) indicating decimal digit
2. A pause of 1.5 s
3. “n” short blinks (where “n”= 1 to 9)
4. A pause of approximately 3 s,
5. When all the error codes are displayed, the sequence finishes with a LED blink of 3 s
6. The sequence starts again.
Example: Error 12 8 6 0 0.
After activation of the SDM, the front LED will show:
1. One long blink of 750 ms (which is an indication of the decimal digit) followed by a pause of 1.5 s
2. Two short blinks of 250 ms followed by a pause of 3 s
3. Eight short blinks followed by a pause of 3 s
4. Six short blinks followed by a pause of 3 s
5. One long blink of 3 s to finish the sequence
6. The sequence starts again.
How to Activate
Activate the SDM 
The blinking front LED will show the entire content of the LAYER 2 error buffer, this works in “normal operation” mode or when SDM (via hardware pins) is activated when the tv set is in protection.
Important remark:
For all errors detected by MIPS which are fatal => rebooting of the TV set (reboot starts after LAYER 1 error blinking), one should short the solder paths at start-up from the power OFF state by mains interruption and not via the power button to trigger the SDM via the hardware pins.
Transmit the commands “MUTE” - “062500” - “OK” with a normal RC. The complete error buffer is shown. Take notice that it takes some seconds before the blinking LED starts.
Transmit the commands “MUTE” - “06250x” - “OK” with a normal RC (where “x” is a number between 1 and 5). When x = 1 the last detected error is shown, x = 2 the second last error, etc.... Take notice that it takes some seconds before the blinking LED starts.
