Specifications
Service Modes, Error Codes, and Fault Finding
EN 10 L05.1U AA5.
How to exit
Switch the set to STANDBY by pressing the POWER button on
the remote control transmitter or the television set.
If you turn the television set “off” by removing the AC power
(i.e., unplugging the television) without using the POWER
button, the television set will remain in SAM when AC power is
re-applied, and the error buffer is not cleared.
5.2.3 Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV’s operation settings. The call center can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set. This helps the call center to
diagnose problems and failures in the TV set before making a
service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.
How to enter
To enter CSM, press the following key sequence on the remote
control transmitter: “123654” (do not allow the display to time
out between entries while keying the sequence).
Upon entering the Customer Service Mode, the following
screen will appear:
Figure 5-3 CSM menu
Menu explanation
1. Indication of the decimal value of the operation hours
counter, Software identification of the main microprocessor
(see "Service Default or Alignment Mode" for an
explanation), and the service mode (CSM= Customer
Service Mode).
2. Displays the last five errors detected in the error code
buffer.
3. Displays the option bytes.
4. Displays the type number version of the set.
5. Reserved item for P3C call centers.
6. Indicates the television is receiving an "IDENT" signal on
the selected source. If no "IDENT" signal is detected, the
display will read "NOT TUNED"
7. Displays the detected Color system (e.g. PAL/NTSC).
8. Displays the detected Audio (e.g. stereo/mono).
9. Displays the picture setting information.
10. Displays the sound setting information.
How to exit
To exit CSM, use one of the following methods:
• Press the MENU, STATUS/EXIT, or POWER button on the
remote control transmitter.
• Press the POWER button on the television set.
5.2.4 Digital Customer Service Mode (DCSM)
Purpose
The Digital Customer Service Mode shows error codes and
information on the TV’s digital operation settings. The call
center can instruct the customer (by telephone) to enter DCSM
in order to identify the digital status of the set. This helps the
call center to diagnose problems and failures with the ATSC
part before making a service call.
The DCSM is a read-only mode; therefore, modifications are
not possible in this mode, with exception of the digital error
buffer. This error buffer can be cleared in DCSM.
How to enter
To enter DCSM, the set has to be in digital mode. When the set
is in digital mode, press the following key sequence on the
remote control transmitter: “123654” (do not allow the display
to time out between entries while keying the sequence).
Upon entering the Digital Customer Service Mode, the
following screen will appear:
