Service Modes, Error Codes, and Fault Finding
How to Exit SDM Use one of the following methods: � Switch the set to STANDBY 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.

processor recognizes a corrupted NVM, the �initialize NVM� line will be highlighted. Now, you can do two things (depending 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 Standby mode. If the NVM was corrupted or empty before this action, it will be initialised first (loaded with default values). This initialising can take up to 20 seconds.

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 VIPER software (main software) (example: JA30E1.2.3.4_12345 = AAAAB_X.Y.W.Z_NNNNN). � 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). � NNNNN= last five digits of 12nc code of the software. � B. SBY PROC Version. Displays the software version of the standby 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 standby 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. It will then display the message �UNKNOWN� here. Not all errors will display a defective module name. � Reset Error Buffer. When you press �cursor right� and then the �OK� button, the error buffer is reset. � Alignments. This will activate the �ALIGNMENTS� submenu. � Dealer Options. Extra features for the dealers. � Options. Extra features for Service. For more info 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. � 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
