How to Activate SDM
For this chassis there are two kinds of SDM: an analogue SDM 
and a digital SDM. Tuning will happen according 

Table 5-1

.

•

Analogue SDM: use the standard RC-transmitter and key 
in the code “062596”, directly followed by the “MENU” (or 
“HOME”) button. 
Note: It is possible that, together with the SDM, the main 
menu will appear. To switch it “off”, push the “MENU” (or 
"HOME") button again.
Analogue SDM can also be activated by grounding for a 
moment the solder path on the SSB, with the indication 
“SDM” (see 

Service mode pad

).

•

Digital SDM: use the standard RC-transmitter and key in 
the code “062593”, directly followed by the “MENU” (or 
"HOME") button.
Note: It is possible that, together with the SDM, the main 
menu will appear. To switch it “off”, push the “MENU” (or 
"HOME") button again.

After activating this mode, “SDM” will appear in the upper right 
corner of the screen (when a picture is available).

How to Navigate
When the “MENU” (or “HOME”) button is pressed on the RC 
transmitter, the TV set will toggle between the SDM and the 
normal user menu. 

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.

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 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.

Audio: 3 kHz left, 1 kHz right.

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.

As most signals are digital, it will be diffi cult to measure wave-
forms with a standard oscilloscope. However, several key ICs 
are capable of generating test patterns.

Hardware Info.
–

A. SW Version. Displays the software version of the 
main software (example: Q555X-1.2.3.4 = 
AAAAB_X.Y.W.Z). 
•

AAAA= the chassis name.

•

B= the SW branch version. This is a sequential 
number (this is no longer the region indication, as 
the software is now multi-region).

•

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).

–

B. STBY PROC Version. Displays the software 
version of the stand-by processor.

•

Store - go right. All options and alignments are stored 
when pressing “cursor right” (or the “OK” button) and then 
the “OK”-button.

•

Operation hours display. Displays the accumulated total 
of operation hours of the screen itself. In case of a display 
replacement, reset to “0” or to the consumed operation 
hours of the spare display.

•

SW Maintenance.
–

SW Events. In case of specific software problems, the 
development department can ask for this info.

–

HW Events. In case of specific software problems, the 
development department can ask for this info :
- Event 26: refers to a power dip, this is logged after 
the TV set reboots due to a power dip.
- Event 17: refers to the power OK status, sensed even 
before the 3 x retry to generate the error code.

•

Test settings. For development purposes only.

•

Development file versions. Not useful for Service 
purposes, this information is only used by the development 
department.

•

Upload to USB. To upload several settings from the TV to 
an USB stick, which is connected to the SSB. The items are 
“Channel list”, “Personal settings”, “Option codes”, 
“Alignments”, “Identification data” (includes the set type 
and prod code + all 12NC like SSB, display, boards), 
“History list”. The “All” item supports to upload all several
items at once.
First a directory “repair\” has to be created in the root 
of the USB stick.
To upload the settings, select each item separately, press 
“cursor right” (or the “OK” button), confirm with “OK” and 
wait until the message “Done” appears. In case the 
download to the USB stick was not successful, “Failure” will 
be displayed. In this case, check if the USB stick is 
connected properly and if the directory “repair” is present in 
the root of the USB stick. Now the settings are stored onto 
the USB stick and can be used to download into another TV 
or other SSB. Uploading is of course only possible if the 
software is running and preferably a picture is available. 
This method is created to be able to save the customer’s 
TV settings and to store them into another SSB.

•

Download from USB. To download several settings from 
the USB stick to the TV, same way of working needs to be 
followed as described in “Upload to USB”. To make sure 
that the download of the channel list from USB to the TV is 
executed properly, it is necessary to restart the TV and 
tune to a valid preset if necessary. The “All” item supports 
to download all several items at once.

–   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.

•

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 maximum 10 errors). The most recent 
error is displayed at the upper left (for an error explanation 
see section “

5.5 Error Codes

”).

•

Reset Error Buffer. When “cursor right” (or “OK” button) 
pressed here, followed by the “OK” button, the error buffer 
is reset.

•

Alignments. This will activate the “ALIGNMENTS” sub-
menu. See Chapter 

6. Alignments

.

•

Dealer Options. Extra features for the dealers.

•

Options. Extra features for Service. For more info 
regarding option codes, see chapter 

6. Alignments

.

Note that if the option code numbers are changed, these 
have to be confirmed with pressing the “OK” button before 
the options are stored, otherwise changes will be lost.

•

Initialize NVM. The moment the processor recognizes a 
corrupted NVM, the “initialize NVM” line will be highlighted. 
Now, two things can be done (dependent of the service 
instructions at that moment):

–     Save the content of the NVM for development analysis, 

before initializing. This will give the Service department 
an extra possibility for diagnosis (e.g. when Develop-
ment asks for this). 

–     Initialize the NVM.

Note: When the NVM is corrupted, or replaced, there is a high 
possibility that no picture appears because the display code is 
not correct. So, before initializing the NVM via the SAM, a pic-
ture is necessary and therefore the correct display option has 
to be entered. Refer to Chapter 

6. Alignments

 for details. To 

adapt this option, it’s advised to use 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” (or “HOME”) 
button and “XXX” (where XXX is the 3 digit decimal display 
code as mentioned on the below table).

 S5551_0.9.21.0

How to Navigate
• 

In SAM, the menu items can be selected with the 
“CURSOR-DOWN/UP/LEFT/RIGHT” knob of the RC 
transmitter.

 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 Stand-by 
mode. If the NVM was corrupted or empty before this action, it 
will be initialized fi rst (loaded with default values). This initial-
izing can take up to 20 seconds.

editor. For NET TV the set “type number” must 

be entered correctly.Also the production code (serial 
number) can be entered here via the RC-transmitter.
Correct data can be found on the side/rear sticker.

“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.

•

With the “OK” key, it is possible to activate the selected 
action.

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.

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 and there 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 dump file 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 flashdump 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. Only the latest error is displayed (see also 
section 

5.5 Error Codes

).

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.

    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. The 
update can 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. The update can be done via the NVM 

editor available in SAM.

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.

NVM. Note that if an NVM is replaced or is initialized after 
corruption, this identifi cation number has to be re-written 
to NVM. This identifi cation number is the 12nc number of 
the SSB.

•

        Stand-by SW. Displays the build-in stand-by processor 

software version. Upgrading this software will be possible 
via USB (see section 

5.9 Software Upgrading

)

How to Exit CSM
Press “MENU” (or "HOME") / “Back” key on the RC-transmitter.

When the TV is in a protection state due to an error detected by 
stand-by software (error blinking is displayed) and SDM is 
activated via shortcutting the SDM solder path on the SSB, the 
TV starts up until it reaches the situation just before protection. 
So, this is a kind of automatic stepwise start-up. In combination 
with the start-up diagrams below, you can see which supplies 
are present at a certain moment. Caution: in case the start-up 
in this mode with a faulty FET 7U0X is done, you can destroy 
all IC’s supplied by the +1V8 and +1v1, due to overvoltage (12V 

on XVX-line). It is recommended to measure first the FET 
7U0X or others FET’s on shortcircuit before activating SDM via 
the service pads.

The abbreviations “SP” and “MP” in the figures stand for:
•

SP: protection or error detected by the Stand-by 
Processor.

•

MP: protection or error detected by the MIPS Main 
Processor.
