Figure 5-1 Service mode pads
After activating this mode, "SDM" will appear in the upper right
corner of the screen (if you have picture).
How to Navigate
When you press the "MENU" button on the RC transmitter, the
set will toggle between the SDM and the normal user menu
(with the SDM mode still active in the background).
How to Exit SDM
Use one of the following methods:
• Switch the set to STAND-BY via the RC-transmitter.
• Via a standard customer RC-transmitter: key in "00"-
sequence.
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" button. After activating SAM
with this method a service warning will appear on the screen,
you can continue by pressing the red button on the RC.
Contents of SAM:
• Hardware Info.
– A. SW Version. Displays the software version of the
main software (example: Q531U-1.2.3.4 =
AAAAB_X.Y.W.Z).
• AAAA= the software name.
• B= the region: A= AP, E= EU, L= LatAm, U = US.
For AP sets it is possible that the Europe software
version is used.
• 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.

Q523.1U LA
• 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 maximal 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see paragraph "Error Codes").
• Reset Error Buffer. When you press "cursor right" and
then the "OK" button, the error buffer is reset.
• Alignments. This will activate the "ALIGNMENTS" sub-
menu.
• Dealer Options. Extra features for the dealers.
• Options. Extra features for Service. For more information
regarding option codes, see chapter 8.
Note that if you change the option code numbers, you have
to confirm your changes with the "OK" button before you
store the options. Otherwise you will lose your changes.
• Initialize NVM. When an NVM was corrupted (or replaced)
in the former EMG based chassis, the microprocessor
replaces the content with default data (to assure that the
set can operate). However, all preferences and alignment
values are gone now, and option numbers are not correct.
Therefore, this was a very drastic way. In this chassis, the
procedure is implemented in another way: The moment the
processor recognizes a corrupted NVM, the "initialize
NVM" line will be highlighted. Now, you can do two things
(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 (same as in the past, however now it
happens conscious).
Note: When you have a corrupted NVM, or you have replaced
the NVM, there is a high possibility that you will not have picture
any more because your display option is not correct. So, before
you can initialize your NVM via the SAM, you need to have
picture and therefore you need the correct display option. To
adapt this option, you can use ComPair (the correct HEX
values for the options can be found in the table below) 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" button and
"XXX" (where XXX is the 3 digit decimal display option code as
mentioned in the first column of the next table). 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. 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.
• Operation hours PDP. Here you are able to reset the
operations hours of the plasma display. This has to be
done in case of replacement of the display. Not applicable
to LCD sets.
• Test settings. for development purposes only.
• Upload to USB. Here you are able to upload several
settings from the TV to a USB stick which is connected to
the Side I/O. The items are "Channel list", "Personal
settings", "Option codes" and "Display-related alignments".
First you have to create a directory "repair\" in the root of
the USB stick.To upload the settings you have to select
each item separately, press "cursor right", confirm with
"OK" and wait until "Done" appears. Now the settings are
