HOW TO ENTER CUSTOMER SERVICE MODE [CSM] - PHILIPS 40PFL6606D - LCD TVs


CUSTOMER SERVICE MODE
Purpose
   When a customer is having problems with his TV-set, he can call his dealer or the Customer Helpdesk. The service technician can then ask the customer to activate the CSM, in order to identify the status of the set. Now, the service technician can judge the severity of the complaint. In many cases, he can advise the customer how to solve the problem, or he can decide if it is necessary to visit the customer.  The CSM is a read only mode; therefore, modifications in this mode are not possible.
   When in this chassis CSM is activated, a test pattern will be  displayed during 5 seconds (1 second Blue, 1 second Green and 1 second Red, then again 1 second Blue and 1 second Green). This test pattern is generated by the PNX51X0 (located on the 200Hz board as part of the display). So if this test pattern is shown, it could be determined that the back end video chain (PNX51X0 and display) is working.  For TV sets without the PNX51X0 inside, every menu from CSM will be used as check for the back end chain video.
   When CSM is activated andthere is a USB stick connected to the TV set, the software will dump the CSM content to the USB stick. The file (CSM_model number_serial number.txt) will be saved in the root of the USB stick. This info can be handy if no information is displayed.
When in CSM mode (and a USB stick connected), pressing “OK” will create an extended CSM dumpfile on the USB stick. This file (Extended_CSM_model number_serial number.txt) contains:
• The normal CSM dump information,
• All items (from SAM “load to USB”, but in readable format),
• Operating hours,
• Error codes,
• SW/HW event logs.
   To have fast feedback from the field, a flash dump can be requested by development. When in CSM, push the “red” button and key in serial digits ‘2679’ (same keys to form the word ‘COPY’ with a cellphone). A file “Dump_model number_serial number.bin” will be written on the connected USB device. This can take 1/2 minute, depending on the quantity of data that needs to be dumped.  Also when CSM is activated, the LAYER 1 error is displayed via blinking LED.
How to Activate CSM
Key in the code “123654” via the standard RC transmitter.  Note: Activation of the CSM is only possible if there is no (user) menu on the screen.
How to Navigate
By means of the “CURSOR-DOWN/UP” knob on the RC transmitter, can be navigated through the menus.
Contents of CSM
The contents are reduced to 3 pages: General, Software versions and Quality items. The group names itself are not shown anywhere in the CSM menu.
General
• Set Type.This information is very helpful for a helpdesk/workshop as reference for further diagnosis. In this way, it is not necessary for the customer to look at the rear of the TV-set. Note that if an NVM is replaced or is initialized after corruption, this set type has to be re-written to NVM. ComPair will foresee in a possibility to do this. The update can also be done via the NVM editor available in SAM.
• Production Code.Displays the production code (the serial number) of the TV. 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. The update can also be done via the NVM editor available in SAM.
• Installed date.Indicates the date of the first installation of the TV. This date is acquired via time extraction.
• Options 1.Gives the option codes of option group 1 as set in SAM (Service Alignment Mode).
• Options 2.Gives the option codes of option group 2 as set in SAM (Service Alignment Mode).
• 12NC SSB.Gives an identification of the SSB as stored in NVM. Note that if an NVM is replaced or is initialized after corruption, this identification number has to be re-written to NVM. ComPair will foresee in a possibility to do this. This identification number is the 12nc number of the SSB.
• 12NC display.Shows the 12NC of the display.
• 12NC supply.Shows the 12NC of the power supply.
• 12NC 200Hz board.Shows the 12NC of the 200Hz Panel (when present).
• 12NC AV PIP.Shows the 12NC of the AV PIP board (when present).
Software versions
• Current main SW.Displays the build-in main software version. In case of field problems related to software, software can be upgraded. As this software is consumer upgradeable, it will also be published on the Internet.  Example: Q55xx1.2.3.4
• Stand-by SW.Displays the build-in stand-by processor software version. Upgrading this software will be possible via ComPair or via USB.
• e-UM version.Displays the electronic user manual SWversion (12NC version number). Most significant number here is the last digit.
• AV PIP software.
• 3D dongle software version.
Quality items
• Signal quality.Bad / average /good (not for DVB-S).  • Ethernet MAC address. Displays the MAC address present in the SSB.
• Wireless MAC address.Displays the wireless MAC address to support the Wi-Fi functionality.
• BDS key.Indicates if the set is in the BDS status.
• CI module.Displays status if the common interface module is detected.
• CI + protected service.Yes/No.
• Event counter:
S : 000X 0000(number of software recoveries : SW EVENT-LOG #(reboots)
S : 0000 000X (number of software events : SW EVENTLOG #(events)
H : 000X 0000(number of hardware errors.
H : 0000 000X (number of hardware events : SW EVENTLOG #(events).
How to Exit CSM
Press “MENU” (or "HOME") / “Back” key on the RC-transmitter.
