PHILIPS PFL-SERIES LCD TVs SERVICE MODE & ERROR CODES - LED BLINKING CODES -
To
perform (software) alignments.
To
change option settings.
To
easily identify the used software version.
To
view operation hours.
To
display (or clear) the error code buffer.
To
Activate SAM
Via
a standard RC transmitter: Key in the code “062596” directly followed by the
“INFO” or “OK” button. After activating SAM with this method a service warning
will appear on the screen, continue by pressing the “OK” button on the remote control.
Contents
of SAM
Hardware
Info.
[A].
SW Version. Displays the software version of the main
software (example:QF1XX-1.2.3.4 =
AAABB_X.Y.W.Z).
AAA=
the chassis name.
BB=
Product ID.
X.Y.W.Z=
the software version, where X is the main version number (different numbers are
not compatible with one another) and Y.W.Z is the sub version number (a higher
number is always compatible with a lower number).
[B].
Standby processor version. Displays the software version of the standby
processor.
[C]. Production Code.
Displays the production code of the TV, this is the serial number as printed on
the back of the TV set. Note that if an NVM is replaced or is initialized after
corruption, this production code has to be re-written to NVM. The update can be
done via the NVM editor available in SAM.
Operation hours. Displays
the accumulated total of operation hours (not the standby hours). Every time
the TV is switched “on/off”, 0.5 hours is added to this number. Errors
(followed by maximum 10 errors). The most recent error is displayed at the
upper left.
Reset
Error Buffer. When “cursor right” (or “OK” button) pressed here, followed by
the “OK” button, the error buffer is reset.
Alignments.
This will activate the “ALIGNMENTS” submenu.
Options
numbers. Extra features for Service. For more info regarding option codes. Note that if the option code numbers are
changed, these
have
to be confirmed with pressing the “OK” button before the options are stored,
otherwise changes will be lost.
Initialize
NVM.The moment the processor recognizes a corrupted NVM, the “initialize NVM”
line will be highlighted. Now, two
things can be done (dependent of the service instructions at that moment): Save the content of the NVM via ComPair for
development analysis, before initializing. This will give the Service
department an extra possibility for diagnosis (e.g. when Development asks for
this).
Initialize
the NVM. Note: When the NVM is
corrupted, or replaced, there is a high possibility that no picture appears
because the display code is not correct. So, before initializing the NVM via the
SAM, a picture is necessary and therefore the correct display option has to be
entered.
To
adapt this option, it’s advised to use compare, or a method via a standard RC
(described below). Changing the display
option via a standard RC: Key in the code “062598” directly followed by the
“MENU” (or "HOME") button and “XXX” (where XXX is the 3 digit decimal
display code as mentioned on the sticker in the set). Make sure to key in all
three digits, also the leading zero’s. If the above action is successful,
the front LED will go out (Standby) as an indication that the RC sequence was
correct. After the display option is changed in the NVM, the TV will go to the
Standby mode. If the NVM was corrupted or empty before this action, it will be
initialized first (loaded with default values). This initializing can take up
to 20 seconds.
To
Navigate In SAM, the menu items can be selected 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. – (De) activate the
selected sub menu. With
the “OK” key, it is possible to activate the selected action.
To
Exit SAM
Use
one of the following methods:
Switch
the TV set to STAND-BY via the RC-transmitter.
Via
a standard RC-transmitter, key in “00” sequence, or select the “BACK” key.
How
to Read the Error Buffer
Use
one of the following methods:
On
screen via the SAM (only when a picture is visible).
Eg:
00
00 00 00 00: No errors detected
23
00 00 00 00: Error code 23 is the last and only detected error.
37
23 00 00 00: Error code 23 was first detected and error code 37 is the last
detected error. Note that no protection
errors can be logged in the error buffer.
How
to Clear the Error Buffer
Use
one of the following methods:
By
activation of the “RESET ERROR BUFFER” command in the SAM menu.
If
the content of the error buffer has not changed for 50+ hours, it resets
automatically.
[Take
notice that some errors need several minutes before they start blinking or
before they will be logged. So in case of problems wait 2 minutes from start-up
onwards, and then check if the front LED is blinking or if an error is logged.]
The
Blinking LED Procedure.
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 is put in CSM. This will be only
one digit error, namely the one that is referring to the defective board, which
causes the failure of the TV.
Blinking
LED procedure LAYER 2 error.
Via this procedure, the contents of the error
buffer can be made visible via the front LED. In this case the error contains 2
digits and will be displayed when SDM (hardware pins) is activated. This is
especially useful for fault finding and gives more details regarding the root
cause of the defective board.
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 to9) 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 s (spacer).
6.
The sequence starts again.
Example:Error
12 8 6 0 0.
After
activation of the SDM, the front LED will show:
1.
One long blink of 750 ms (which is an 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.
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.
Activate
the SDM. The blinking front LED will show the entire content of the LAYER 2
error buffer, this works in “normal operation” mode or when SDM (via hardware
pins) is activated when the TV set is in protection.
To Activate SDM
Analogue SDM: use the RC-transmitter and key in the code
“062596”, directly followed by the “MENU” (or “HOME”) button. It is possible that, together with the SDM,
the main menu will appear. To switch it “off”, push the “MENU” (or
"HOME") button again.
Digital SDM: use the RC-transmitter and key in the code
“062593”, directly followed by the “MENU” (or "HOME") button. Note: It is possible that, together with the
SDM, the main menu will appear. To switch it “off”, push the “MENU” (or
"HOME") button again.
