Philips BJ2.4U Service Manual

Service Modes, Error Codes, and Fault Finding EN 15BJ2.4U/BJ2.5U PA 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 SAMVia a standard RC transmitter: key in the code “062596”directly followed by the “INFO” button. After activating SAMwith 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 versionof 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 themain version number (different numbers are notcompatible with one another) and Y is the subversion number (a higher number is alwayscompatible with a lower number). The last twodigits are used for development reasons only, sothey will always be zero in official releases.• NNNNN= last five digits of 12nc code of thesoftware.– B. SBY PROC Version. Displays the software versionof the stand-by processor.– C. Production Code. Displays the production code ofthe TV, this is the serial number as printed on the backof the TV set. Note that if an NVM is replaced or isinitialized after corruption, this production code has tobe re-written to NVM. ComPair will foresee in apossibility to do this.• Operation Hours. Displays the accumulated total ofoperation hours (not the stand-by hours). Every time theTV is switched "on/off", 0.5 hours is added to this number.• Errors. (Followed by maximal 10 errors). The most recenterror is displayed at the upper left (for an error explanationsee paragraph “Error Codes”).• Defective Module. Here the module that generates theerror is displayed. If there are multiple errors in the buffer,which are not all generated by a single module, there isprobably another defect.Take into account that not allerrors will create a defective module message.• Reset Error Buffer. When you press “cursor right” andthen 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 microprocessorreplaces the content with default data (to assure that theset can operate). However, all preferences and alignmentvalues are gone now, and option numbers are not correct.Therefore, this was a very drastic way. In this chassis, theprocedure is implemented in another way: The moment theprocessor recognizes a corrupted NVM, the “initializeNVM” 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 fordevelopment analysis, before initializing. This will givethe Service department an extra possibility fordiagnosis (e.g. when Development asks for this).– Initialize the NVM (same as in the past, however now ithappens conscious).Note: When you have a corrupted NVM, or you have replacedthe NVM, there is a high possibility that you will not have pictureany more because your display option is not correct. So, beforeyou can initialize your NVM via the SAM, you need to have apicture and therefore you need the correct display option. Toadapt this option, use ComPair. The correct HEX values for theoptions can be found in the table below.The display optioncode (decimal) is also available on the option code stickerlocated inside the TV mentioned by “Screen Diversity” e.g. 044.Remark: use always 3 digits for the display option code, for “7”=> “007”.
