Service Modes, Error Codes, and Fault Finding

EN 16 LC7.5E LA5.

5.2.2 Service Default Mode (SDM)

Purpose

Set the TV in SDM mode in order to be able to:

• Create a pre-defined setting for measurements to be

made.

• Override software protections.

• Start the blinking LED procedure.

• Read the error buffer.

• Check the life timer.

Specifications

Table 5-1 SDM default settings

• Set linear video and audio settings to 50%, but volume to

25%. Stored user settings are not affected.

• All service-unfriendly modes (if present) are disabled, since

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.

– Child lock or parental lock (manual or via V-chip).

– Skipping, blanking of “Not favourite”, “Skipped” or

“Locked” presets/channels.

– Automatic storing of Personal Preset or Last Status

settings.

– Automatic user menu time-out (menu switches back/

OFF automatically.

– Auto Volume levelling (AVL).

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.

On Screen Menu

After activating SDM, the following screen is visible, with SDM

in the upper right corner of the screen to indicate that the

television is in Service Default Mode.

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.

• 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”.

•

ress 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

as the power is supplied again. The error buffer will not be

cleared.

• In case the set is in Factory mode by accident (with “F”

displayed on screen), by pressing and hold “VOL-“ and

“CH-” together should leave Factory mode.
