SERVICE MODE 

Service Modes
Service Default mode (SDM) and Service Alignment Mode (SAM) offers several features for the service technician, while the Customer Service Mode (CSM) is used for communication between the call centre and the customer.
Service Default Mode (SDM)
How to Activate SDM
Analogue SDM: use the standard RC-transmitter and key in the code “062596”, directly followed by the “MENU” (or “HOME”) button.
Digital SDM: use the standard RC-transmitter and key in the code “062593”, directly followed by the “MENU” (or "HOME") button.
How to Exit SDM
Use one of the following methods:
# Switch the set to STAND-BY via the RC-transmitter.
# Via a standard customer RC-transmitter: key in “00”- sequence.
Service Alignment Mode (SAM)
How to Activate SAM
Via a standard RC transmitter: Key in the code “062596” directly followed by the “INFO” or “OK” button. After activating SAM with this method a service warning will appear on the screen, continue by pressing the “OK” button on the RC.
How to Exit SAM
Use one of the following methods:
# Switch the TV set to STAND-BY via the RC-transmitter.
# Via a standard RC-transmitter, key in “00” sequence, or select the “BACK” key.
Customer Service Mode (CSM)
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.
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 Exit CSM
Press “MENU” (or "HOME") / “Back” key on the RC-transmitter.
How to Clear the Error Buffer
Use one of the following methods:
# By activation of the “RESET ERROR BUFFER” command in the SAM menu.
# If the content of the error buffer has not changed for 50+ hours, it resets automatically.
COMMON ERRORS
Rebooting. When a TV is constantly rebooting due to internal problems, most of the time no errors will be logged or blinked. This rebooting can be recognized via a Hyperterminal . It’s shown that the loggings which are generated by the main software keep continuing.
Error 13 (I2C bus 3, SSB bus blocked). Current situation: when this error occurs, the TV will constantly reboot due to the blocked bus.
# Error 14 (I2C bus 2, TV set bus blocked). Current situation: when this error occurs, the TV will constantly reboot due to the blocked bus.
# Error 18 (I2C bus 4, Tuner bus blocked). In case this bus
is blocked, short the “SDM” solder paths on the SSB during
startup, LAYER error 2 = 18 will be blinked.
# Error 15 (PNX8550 doesn’t boot). Indicates that the main processor was not able to read his bootscript. This error will point to a hardware problem around the PNX8550 (supplies not OK, PNX 8550 completely dead, I2C link between PNX and Stand-by Processor broken, etc...). When error 15 occurs it is also possible that I2C1 bus is blocked (NVM). I2C1 can be indicated in the schematics as follows: SCL-UP-MIPS, SDA-UP-MIPS. LAYER 2 error = 28 will be logged and displayed via the Other root causes for this error can be due to hardware problems regarding the DDR’s and the bootscript reading from the PNX8550.
# Error 16 (12V). This voltage is made in the power supply and results in protection (LAYER 1 error = 3) in case of absence. When SDM is activated we see blinking LED LAYER 2 error = 16.
# Error 17 (Invertor or Display Supply). Here the status of the “Power OK” is checked by software, no protection will occur during failure of the invertor or display supply (no picture), only error logging. LED blinking of LAYER 1 error = 3 in CSM, in SDM this gives LAYER 2 error = 17.
# Error 21 (PNX51X0). When there is no I2C communication towards the PNX51X0 after start-up, LAYER 2 error = 21 will be logged and displayed via the blinking LED procedure if SDM is switched on. This device is located on the 200 Hz panel from the display.
# Error 23 (HDMI). When there is no I2C communication towards the HDMI mux after start-up, LAYER 2 error = 23 will be logged and displayed via the blinking LED procedure if SDM is switched on.
# Error 24 (I2C switch). When there is no I2C communication towards the I2C switch, LAYER 2 error = 24 will be logged and displayed via the blinking LED procedure when SDM is switched on. Remark: this only works for TV sets with an I2C controlled screen included.
# Error 28 (Channel dec DVB-S). When there is no I2C communication towards the DVB-S channel decoder, blinking LED procedure if SDM is switched on.
# Error 31 (Lnb controller). When there is no I2C communication towards this device, LAYER 2 error = 31 will be logged and displayed via the blinking LED procedure if SDM is activated.
# Error 34 (Tuner). When there is no I2C communication towards the tuner during start-up, LAYER 2 error = 34 will be logged and displayed via the blinking LED procedure when SDM is switched on.
# Error 35 (main NVM). When there is no I2C communication towards the main NVM during start-up, LAYER 2 error = 35 will be displayed via the blinking LED procedure when SDM is switched “on”. All service modes (CSM, SAM and SDM) are accessible during this failure, observed in the Uart logging as follows: "<< ERRO >>> PFPOW_.C: First Error (id19, Layer_1= 2 Layer_= 35)".
# Error 36 (Tuner DVB-S). When there is no I2C communication towards the DVB-S tuner during start-up, LAYER 2 error = 36 will be logged and displayed via the blinking LED procedure when SDM is switched “on”.
# Error 42 (Temp sensor). Only applicable for TV sets equipped with temperature devices.
# Error 53. This error will indicate that the PNX8550 has read his bootscript (when this would have failed, error 15 would blink) but initialization was never completed because of hardware problems (NAND flash, ...) or software initialization problems. Possible cause could be that there is no valid software loaded (try to upgrade to the latest main software version). Note that it can take a few minutes before the TV starts blinking LAYER 1 error = 2 or in SDM, LAYER 2 error = 53.
# Error 64. Only applicable for TV sets with an I2C controlled screen.
