ervice Modes
Note:
For the new model range, a new remote control (RC) is
used with some renamed buttons. This has an impact on the
activation of the Service modes. For instance the old “MENU”
button is now called “HOME” (or is indicated by a “house” icon).
Service Default mode (SDM) and Service Alignment Mode
(SAM) offer several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer.
This chassis also offers the option of using ComPair, a
hardware interface between a computer and the TV chassis. It
offers the abilities of structured troubleshooting, error code
reading, and software version read-out for all chassis.
(see also section 5.3.1 ComPair).

Giving overview of:
–
Op. Hours.
During the life time cycle of the TV, a life
timer is kept. It counts the normal operation hours, not
the Stand-by hours. The actual value of the life timer is
displayed in SAM in decimal value. For every two start-
ups the counter increases by one. Min. 5 digits are
displayed in decimal digits. In detail:
•
Every 2x cold start-ups, to display a picture,
increases the counter by 1 (i.e. interrupt the mains
supply 2x while the set is ON).
•
Every 2x warm start-ups (from Stand-by), to
display a picture, increases the counter by 1.
•
Every hour of normal operating increases the
counter by 1 (i.e. if a set is continue ON for 2 hours,
then increase the counter by 2).
•
Stand-by hours are NOT counted.

To upload several settings from the TV
to an USB stick. See 5-1 USB Copy content. To upload
the settings, press “arrow right” (or the “OK button),
confirm with “OK” and wait until “OK” appears. Now the
settings are stored onto the USB stick can be used to
download to another TV or other SSB. Uploading is of

picture is available. This method is created to be able
to save the customer’s TV settings and to store them
into another SSB.
–
