Service Modes, Error Codes, and Fault Finding
5.
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 “OK”) button. After activating
SAM with this method a service warning will appear on the
screen, continue by pressing the “OK” button on the RC.

•
Hardware Info.
–
A. SW Version.
Displays the software version of the
main software (
example:
Q555X-1.2.3.4 =
AAAAB_X.Y.W.Z).
•
AAAA
= the chassis name.
•
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. STBY 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 “
•
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.
•
Options.
Extra features for Service. For more info
regarding option codes,
.
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
for details.
To adapt this option, it’s advised to use ComPair (the correct
values for the options can be found in Chapter
)
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 on the sticker in the set). Make sure to key
in all three 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.
•
Operation hours display.
Displays the accumulated total
of operation hours of the screen itself. In case of a display
replacement, reset to “0” or to the consumed operation
hours of the spare display.
•
SW Maintenance.
–
SW Events.
In case of specific software problems, the
development department can ask for this info.
–
HW Events.
In case of specific software problems, the
development department can ask for this info :
- Event 26:
refers to a power dip, this is logged after
the TV set reboots due to a power dip.
- Event 17:
refers to the power OK status, sensed even
before the 3 x retry to generate the error code.
•
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”,
“Alignments”, “Identification data” (includes the set type
and prod code + all 12NC like SSB, display, boards),
“History list”. The “All” item supports to upload all several
items at once.
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 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 into another TV or other SSB. Uploading
is of course only possible if the software is running and
preferably 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 needs to be
followed 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. The “All” item supports
to download all several itels at once.
