How to store SDAM settings
To store settings changed in SDAM leave the top level SDAM menu by using the
POWER button on the remote control transmitter or the television set.
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 SDAM
when AC power is re-applied, and the error buffer is not cleared.
Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and information on the TV operation
settings. The servicer can instruct the customer to enter CSM by telephone and read off
the information displayed. This helps the servicer 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: '1 2
3 6 5 4' (do not allow the display to time out between entries while keying the
sequence).
