PHILIPS 42PF7320 - PLASMA TV - SERVICE ALIGNMENT MODE [SAM] - DISPLAY OPTION CODE - DETAILS



                                                          CHASSIS OVERVIEW              
SERVICE ALIGNMENT MODE [SAM]
  • 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.
TO ACTIVATE SAM MODE
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: BX23U-1.2.3.4_12345 = AAAB_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.
  • 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. It will then display the message “UNKNOWN” here.
  • 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.
  • Initialise 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): à 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). à Initialize the NVM (same as in the past, however now it happens conscious)
  • 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.
  • Store.All options and alignments are stored when pressing “cursor right” 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 info.
  • HW Events. Not functional at the moment this manual is released, description will be published in an update manual if the function becomes available.
TO NAVIGATE
  • In SAM, you can select the menu items with the “CURSOR UP/DOWN” key on the RC-transmitter. The selected item will be highlighted. When not all menu items fit on the screen, move the “CURSOR UP/DOWN” key to display the next/previous menu items.
  • With the “CURSOR LEFT/RIGHT” keys, it is possible to: – (De) activate the selected menu item.  – (De) activate the selected sub-menu.
TO EXIT
Use one of the following methods:
  1. Press the “MENU” button on the RC-transmitter.
  2. Switch the set to STAND-BY via the RC-transmitter.
Note: As long as SAM is activated, it is not possible to change a channel. This could hamper the White Point alignments because you cannot choose your channel/frequency any more.
Workaround: after you have sent the RC code “062596 INFO” you will see the service-warning screen, and in this stage it is still possible to change the channel (so before pressing the “OK” button).
