Extra features for Service.

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
processor recognizes a corrupted NVM, the initialize NVM 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 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).

: 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 a
picture and therefore you need the correct display option. To
adapt this option, use ComPair. The correct HEX values for the
options can be found in the table below.

Not useful for service purposes. In case of

specific software problems, the development
department can ask for this info.

. Not functional at the moment this manual

is released, description will be published in an update
manual if the function becomes available.

In SAM, you can select the menu items with the

key on the RC-transmitter. The selected item

will be highlighted. When not all menu items fit on the
screen, move the

key to display the

next/previous menu items.
With the

keys, it is possible to:

- (De) activate the selected menu item.
- (De) activate the selected submenu.

Use one of the following methods:

Press the

button on the RC-transmitter.

Switch the set to STAND-BY via the RC-transmitter.

: As long as SAM is activated, it is not possible to change

a channel. This could hamper the White Point alignments
because you cannot choose your channel/frequency any more.
Workaround: after you have sent the RC code

,you

will see the service-warning screen, and in this stage it is still possible
to change the channel (so before pressing the

button).

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,

the built-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.

. Displays the built-in stand-by

processor software version. Upgrading this software will be
possible via a PC and a ComPair interface (see chapter
Software upgrade).

. 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 a possibility to do this.

. 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 a possibility to do this.

. Gives the latest five errors of the error buffer. As

soon as the built-in diagnose software has detected an
error the buffer is adapted. The last occurred error is
displayed on the leftmost position. Each error code is
displayed as a 2-digit number. When less than 10 errors
occur, the rest of the buffer is empty (00). See also
paragraph Error Codes for a description.
