The Blinking LED Procedure
The contents of the error buffer can also be made visible
through the “blinking LED” procedure. This is especially
useful when there is no picture.
•
When the SDM is entered, the LED will blink the number
of times equal to the value of the error code. Upon entry
into the SDM, the LED will blink the contents of the error-
buffer. Error-codes greater than/equal to 10 are shown in
the following manner: A long blink of 750 mSeconds
indicating the decimal digit, followed by a pause of 1500
mSeconds. The LED will then blink the number equal to
the error code. When all error-codes are displayed, the
sequence is finished with an LED display of 3 seconds.
At this point the sequence will begin again.
Example:
Error code position 1 2 3 4 5
Error buffer: 12 9 6 0 0
•
After entering SDM:
•
The sequence will begin with 1 long blink of 750
mSeconds, then pause 1500 mSeconds, then blink twice
(indicating error code 12), then the LED will pause for 3
seconds, then blink 9 times (indicating error code 9), then
the LED will pause for 3 seconds, then blink 6 times
(indicating error code 6), then pause 3 seconds and blink
for 3 seconds again, ending the blinking sequence.
NOTE: If errors 1, 2, 3, or 4 occur the LED ALWAYS
blinks indicating the last error which occurred, even if
the set is NOT in service mode.

Customer Service Mode
All A10 PTV sets are equipped with the “Customer Service
Mode” (CSM). CSM is a special service mode that can be
activated and deactivated by the customer, by request of the
service technician/dealer in order to identify the status of the
set. This CSM is a 'read only' mode, therefore modifications
in this mode are not possible.
5.6.1
Entering the Customer Service Mode.
The Customer Service Mode can be switched on:
•
By pressing the MUTE button on the remote control and
any key on the local keyboard (Channel Up, Channel
Down, VOL +, VOL -) on the TV simultaneously for at
least 4 seconds.
When the CSM is activated:
•
picture and sound settings are set to nominal levels
•
Modes that interfere with the behavior of the set are
switched off (sleep timer, auto standby, etc.)
5.6.2
Exit the Customer Service Mode.
The Customer Service Mode will be switched off after:
•
Pressing any key on the remote control (except “Channel
Up” or “Channel Down”)
•
Switching off the TV set by pressing the Power button on
the remote control or the local keyboard.
Exiting CSM resets the TV set back to its initial values.
