Service Modes, Error Codes, and Fault Finding

Extra Info
•
Rebooting. When a TV-set is constantly rebooting due to
internal problems, most of the time no errors will be logged
or blinked. This rebooting can be recognized via
Hyperterminal (for Hyperterminal settings, see section “
,
). It’s shown
that the loggings which are generated by the main software
keep continuing.

The Blinking LED Procedure
5.5.1
Introduction
The blinking LED procedure can be split up into two situations:
•
Blinking LED procedure LAYER 1 error
In this case the error is automatically blinked when the
TV-set is put in CSM.
This will be only one digit error, namely the one that is
referring to the defective board (see table “
”) which causes the failure of the TV.
This is especially useful for home repair and call centres.
The aim is to have service diagnosis from a distance.
•
Blinking LED procedure LAYER 2 error
This procedure makes the contents of the error buffer
visible via the front LED.
The error contains two digits (see table “
”) and is displayed when SAM is activated.
This is especially useful for fault finding and gives more
details regarding the root cause of the defective board.
Important remark
For an empty error buffer, the LED should not blink at all in
CSM or SAM. No spacer will be displayed.
When one of the blinking LED procedures is activated, the front
LED will show (blink) the contents of the error buffer. Error
codes greater then 10 are shown as follows:
1.
“n” long blinks (where “n” = 1 to 9) indicating decimal digit.
2.
A pause of 1.5 s.
3.
“n” short blinks (where “n”= 1 to 9).
4.
A pause of approximately 3 s.
5.
When all the error codes are displayed, the sequence
finishes with a LED blink of 3 seconds (spacer).
6.
The sequence starts again.
Example: Error 12 8 6 0 0.
After activation of the SAM, the front LED will show:
1.
One long blink of 750 ms (indication of the decimal digit)
followed by a pause of 1.5 s.
2.
Two short blinks of 250 ms followed by a pause of 3 s
3.
Eight short blinks followed by a pause of 3 s.
4.
Six short blinks followed by a pause of 3 s.
5.
One long blink of 3 s to finish the sequence (spacer).
6.
The sequence starts again.
5.5.2
How to Activate
Use one of the following methods:
•
Activate the CSM. The blinking front LED will show the
layer 1 error(s), this works in “normal operation” mode or
automatically when the error/protection is monitored by the
standby processor.
In case no picture is shown and there is no LED blinking,
read the logging to detect whether “error devices” are
mentioned. (see section “
,
”).
