Service Alignment Mode (Sam) - Philips 42PF9731D Service Manual

EN 16 5. BJ2.4U/BJ2.5U LA
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. VIPER SW Version. Displays the software version
of the VIPER software (main software) (example:
BJ24U-1.2.3.4_12345 = AAAAB_X.Y.W.Z_NNNNN).
• AAAA= the chassis name.
• B= the region: A= AP, E= EU, L= Latam, U = US.
• X.Y.W.Z= the software version, where X is the
main version number (different numbers are not
compatible with one another) and Y is the sub
version number (a higher number is always
compatible with a lower number). The last two
digits are used for development reasons only, so
they will always be zero in official releases.
• NNNNN= last five digits of 12nc code of the
software.
– 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 maximal 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see paragraph "Error Codes").
• Defective Module. Here the module that generates the
error is displayed. If there are multiple errors in the buffer,
which are not all generated by a single module, there is
probably another defect.Take into account that not all
errors will create a defective module message.
• 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.
• 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).
Service Modes, Error Codes, and Fault Finding
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 a
picture and therefore you need the correct display option. To
adapt this option, use ComPair. The correct HEX values for the
options can be found in the table below.The display option
code (decimal) is also available on the option code sticker
located inside the TV mentioned by "Screen Diversity" e.g. 044.
Remark: use always 3 digits for the display option code, for "7"
=> "007".
