How to Activate
To activate SDM, use one of the following methods:
•
Press the following key sequence on the remote control
transmitter: "062596" directly followed by the MENU button
(do not allow the display to time out between entries while
keying the sequence).
•
Short one of the "Service" jumpers on the TV board during
cold start (see Figures "Service jumper"). Then press the
mains button (remove the short after start-up).
Caution: Activating SDM by shorting "Service" jumpers will
override the DC speaker protection (error 1), the General
2
I
C error (error 4), and the Trident video processor error
(error 5). When doing this, the service-technician must
know exactly what he is doing, as it could damage the
television set.

Menu explanation:
•
HHHHH: Are the operating hours (in decimal).
•
AAAABCD-X.YY: See paragraph "Service Modes" ->
"General" -> "Software Identification, Version, and Cluster"
for the SW name definition.
•
SDM: The character "SDM" to indicate that the TV set is in
Service mode (at top right corner for 16:9 picture ratio, and
at bottom right corner for 4:3 picture ratio).
•
ERR: Shows all errors detected since the last time the
buffer was erased. Five errors possible.
•
OP: Used to read-out the option bytes. See "Options" in the
Alignments section for a detailed description. Seven codes
are possible.
How to Navigate
As this mode is read only, there is not much to navigate. To
switch to other modes, use one of the following methods:
•
Command MENU from the user remote will enter the
normal user menu (brightness, contrast, colour, etc...) with
"SDM" OSD remaining, and pressing MENU key again will
return to the last status of SDM again.
•
To prevent the OSD from interfering with measurements in
SDM, command "OSD" ("STATUS" for NAFTA and
LATAM) from the user remote will toggle the OSD "on/off"
with "SDM" OSD remaining always "on".
•
Press the following key sequence on the remote control
transmitter: "062596" directly followed by the OSD/i+
button to switch to SAM (do not allow the display to time out
between entries while keying the sequence).
How to Exit
Switch the set to STANDBY by pressing the mains button on
the remote control transmitter or on the television set.
If you switch the television set "off" by removing the mains (i.e.,
unplugging the television), the television set will remain in SDM
when mains is re-applied, and the error buffer is not cleared.
The error buffer will only be cleared when the "clear" command
is used in the SAM menu.
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
5.
