Service Modes, Error Codes and Fault Finding
EN 22 EM5A P/M5.
• ‘Operation Hours’ Displays the accumulated total of
operation hours (not the standby hours).
•‘Errors’ (followed by maximal 10 errors). The most recent
error is displayed at the upper left (for an error explanation
see paragraph “Error Codes”).
• ‘Defect. Module’ Here the module that generates the error
is displayed. If there are multiple errors in the buffer, which
are not all generated by a single module, there is probably
another defect. It will then display the message 'Unknown'
here.
• ‘Reset Error Buffer’ When you press the 'OK' button, the
error buffer is reset.
• ‘Alignments’ This will activate the 'Alignments' sub-menu.
• ‘Dealer Options’ Extra features for the dealers.
• ‘Service Options’ Extra features for Service.
• ‘Initialise NVM’ When an NVM was corrupted (or
replaced) in the former EM3 chassis, the microprocessor
replaces the content with default data (to assure that the
set can operate). However, all pre-sets and alignment
values are gone now, and option numbers are also not
correct. So, this was a very drastic way. In the EM5
chassis, the procedure is implemented in another way: The
moment the processor recognises a corrupted NVM, an
extra line will be added to the SAM menu: 'Initialise NVM'.
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 initialising. This will give
the Philips Service department an extra possibility for
diagnosis (e.g. when Development asks for this).
– Initialise the NVM (same as in the past, however now it
happens conscious).
• ‘Store Options’ All options are stored when pressing the
'OK'-button
• ‘Functional Test’ All devices are tested via the 'OK'
button. Eventual errors are displayed in the error buffer.
The error buffer is not erased, the content returns when this
test is terminated.
How to navigate
• In SAM, you can select the menu items with the 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.
– Change the value of the selected menu item.
– Activate the selected submenu.
How to exit SAM
Use one of the following methods:
• Press the 'MENU' button on the RC-transmitter, or
• Switch the set to STANDBY with the RC-transmitter, or
• Press the 'EXIT' button on the DST.
5.2.3 Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer. 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 enter CSM
Use one of the following methods:
• Press the 'MUTE' button on the RC-transmitter
simultaneously with the 'MENU' button on the TV (top
control) for (at least) 4 seconds.
• 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 you can navigate through the five menus.
Contents of CSM
Customer Service Menu 1
• ‘Software version’ (example: EM5EU1-1.0_01234).
Displays the build in software version. In case of field
problems related to software, software flash-RAM
pos.7006 must be changed by a new one. Do this via
soldering. You will find details of the software versions in
the chapter “Software Survey” of the “Product Survey -
Colour Television” publication. This publication is
published four times a year.
• ‘Feature Box’ The 12NC-number of the build in Feature
Box software
• ‘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.
• ‘Code 1’ Gives the last 5 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 3-
digit number. When less than 10 errors occur, the rest of
the buffer is empty ('000'). See also paragraph 5.5 for a
description.
• ‘Code 2’ Gives the first 5 errors of the error buffer. See also
paragraph 5.5 for a description.
• ‘Volume’ Gives the last status of the volume as set by the
customer. The value can vary from 0 (volume is minimum)
to 100 (volume is maximum). Volume values can be
changed via the volume key on the RC-transmitter.
•‘Brightness’ Gives the last status of the brightness as set
by the customer. The value can vary from 0 (brightness is
minimum) to 100 (brightness is maximum). Brightness
values can be changed via the 'CURSOR LEFT' and
'CURSOR RIGHT' keys on the RC-transmitter after
pressing the 'MENU' button and selecting 'PICTURE' and
'BRIGHTNESS'.
•‘Contrast’ Gives the last status of the contrast as set by the
customer. The value can vary from 0 (contrast is minimum)
to 100 (contrast is maximum). Contrast values can be
changed via 'CURSOR LEFT' and 'CURSOR RIGHT' keys
on the RC-transmitter after pressing the 'MENU' button and
selecting 'PICTURE' and 'CONTRAST'.
•‘Colour’ Gives the last status of the colour saturation, as
set by the customer. The value can vary from 0 (colour is
minimum) to 100 (colour is maximum). Colour values can
be changed via 'CURSOR LEFT' and 'CURSOR RIGHT'
keys on the RC-transmitter after pressing the 'MENU'
button and selecting 'PICTURE' and 'COLOUR'.
•‘Hue’ Only relevant for NTSC-signals (e.g. NTSC-DVD-
discs).
Customer Service Menu 2
•‘Sharpness’ Gives the sharpness value. The value can
vary from 0 (sharpness is minimum) to 7 (sharpness is
maximum). In case of bad antenna signals, a too high
value of the sharpness can result in a noisy picture.
Sharpness values can be changed via the 'CURSOR
LEFT' and 'CURSOR RIGHT' keys on the RC-transmitter
after pressing the 'MENU' button and selecting 'PICTURE'
and 'SHARPNESS'.
• ‘Headphone volume’ Gives the last status of the
headphone volume, as set by the customer. The value can
vary from 0 (volume is minimum) to 100 (volume is
maximum). Headphone volume values can be changed via
