5.2.2 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" or "I+" button. After activating
SAM with this method a service warning will appear on the
screen, continue by pressing the red button on the RC.
Contents of SAM (see also
• Hardware Information
– A. SW Version. Displays the software version of the
main software (example: Q5431-0.26.2.0=
AAAaB_X.Y.W.Z).
• AAAA= the chassis name, where "a" indicates the
chip version: e.g. TV543/32= Q543, TV543/82=
Q548, Q543/92= Q549.
• B= the SW branch version. This is a sequential
number (this is no longer the region indication, as
the software is now multi-region).
• X.Y.W.Z= the software version, where X is the
main version number (different numbers are not
compatible with one another) and Y.W.Z is the sub
version number (a higher number is always
compatible with a lower number).
– B. SBY PROC Version. Displays the software version
of the stand-by processor.
– C. Production Code. Displays the production code of
the TV, this is the serial number as printed on the back
of the TV set. Note that if an NVM is replaced or is
initialized after corruption, this production code has to
be re-written to NVM. ComPair will foresee in a
possibility to do this.
• Operation Hours. Displays the accumulated total of
operation hours (not the stand-by hours). Every time the
TV is switched "on/off", 0.5 hours is added to this number.
• Errors (followed by maximum 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see section 5.5 Error
• Reset Error Buffer. When "cursor right" (or the "OK
button) is pressed and then the "OK" button is pressed, the
error buffer is reset.
• Alignments. This will activate the "ALIGNMENTS" sub-
menu. See chapter
• Dealer Options. Extra features for the dealers. See
6-5.
• Options. Extra features for Service. For more information
regarding option codes, see chapter
Note that if the option code numbers are changed, these
have to be confirmed with pressing the "OK" button before
the options are stored. Otherwise changes will be lost.
• Initialize NVM. The moment the processor recognizes a
corrupted NVM, the "initialize NVM" line will be highlighted.
Now, two things can be done (dependent of the service
instructions at that moment):
– Save the content of the NVM via ComPair for
development analysis, before initializing. This will give
the Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
– Initialize the NVM.
• Note: When the NVM is corrupted, or replaced, there is a
high possibility that no picture appears because the display
code is not correct. So, before initializing the NVM via the
SAM, a picture is necessary and therefore the correct
display option has to be entered.
Refer to chapter 6. Alignments

for details. To adapt this
for the options can be found in chapter 8 "Alignments") or
a method via a standard RC (described below).
Changing the display option via a standard RC: Key in the
code "062598" directly followed by the "MENU" (or HOME)
button and "XXX" (where XXX is the 3 digit decimal display
code as mentioned in
digits, also the leading zero's. If the above action is successful,
the front LED will go out as an indication that the RC sequence
was correct. After the display option is changed in the NVM, the
TV will go to the Stand-by mode. If the NVM was corrupted or
empty before this action, it will be initialized first (loaded with
default values). This initializing can take up to 20 seconds.

• Store - go right. All options and alignments are stored
when pressing "cursor right" (or the "OK" button) and then
the "OK"-button.
• SW Maintenance.
– SW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this information.
– HW Events. Not useful for Service purposes. In case
of specific software problems, the development
department can ask for this information.
• Test settings. For development purposes only.
• Development file versions. Not useful for Service
purposes, this information is only used by the development
department.
• Upload to USB. To upload several settings from the TV to
an USB stick, which is connected to the SSB. The items are
"Channel list", "Personal settings", "Option codes",
"Display-related alignments" and "History list". First a
directory "repair\" has to be created in the root of the
USB stick. To upload the settings select each item
separately, press "cursor right" (or the "OK button), confirm
with "OK" and wait until "Done" appears. In case the
Table
download to the USB stick was not successful "Failure" will
appear. In this case, check if the USB stick is connected
properly and if the directory "repair" is present in the root of
the USB stick. Now the settings are stored onto the USB
stick and can be used to download onto another TV or
other SSB. Uploading is of course only possible if the
software is running and if a picture is available. This
method is created to be able to save the customer's TV
settings and to store them into another SSB.
• Download from USB. To download several settings from
the USB stick to the TV. Same way of working as with
uploading. To make sure that the download of the channel
list from USB to the TV is executed properly, it is necessary
to restart the TV and tune to a valid preset if necessary.
Note: The "History list item" can not be downloaded from
USB to the TV. This is a "read-only" item. In case of
specific problems, the development department can ask
for this information.
How to Navigate
• In SAM, the menu items can be selected with the
"CURSOR UP/DOWN" key (or the scroll wheel) on the RC-
transmitter. The selected item will be highlighted. When not
