they interfere with diagnosing/repairing a set. These
service unfriendly modes are:
–

(Sleep) timer.

–

Blue mute/Wall paper.

–

Auto switch “off” (when there is no “ident” signal).

–

Hotel or hospital mode.

Skipping, blanking of “Not favourite”, “Skipped” or
“Locked” presets/channels.

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
I2C 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.

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/

STATUS/INFO/i+

button to switch to SAM (do not allow the

display to time out between entries while keying the
sequence).
