1.0 The scoreboard stays completely switched off
1.1 Press more times the ON/OFF key and observe both the console LCD display and the LED
digits on the frontal. If the LED digits on the frontal work fine, and only the console LCD display
does not turn on, then the fault depends on the LCD display; in this case, please see chapter 2.0.
Otherwise, if also all of the frontal stay switched off, please see the following paragraph.
1.2 Make sure that the external provides its output connector with a voltage of
12Vdc (see Fig.1 on pag.2). If the voltage than +11 Vdc, the has to be
replaced.
You should order the following article:
Art.168 - Power 90-264V/12Vdc 1A, connector XLR
1.3 Open the scoreboard by unscrewing the 4 screws on the back (see Fig.3 and 4 on pag.2).
if there is a +12V power supply on the connector of the (see Fig.5 on pag. 2). The
red wire is positive. If there is not this voltage,
you should check the short path from the CN1 connector to
1.4
For
technicians who want to try to repair it, please see paragraph 1.5, otherwise
order the article below:
Art.0430-1292 - FAV.A507
You should specify the scoreboard of PS series that will use the electronic board,
. If it concerns the article PS-J, clarify whether it is a new, or an
old version (see pictures on pag.1).
Example: Art.0430-1292 - FAV.A507 CPU e for PS-M
1.5. For technicians who want to try to repair the FAV.A507 , we suggest the
following checks:
A) O erify the presence of +12Vdc and of +5Vdc (see Fig.5 and Fig.2 on
pag.2). If there is not the +5Vdc , try to replace the L7805 component.
B) If there is the +5Vdc voltage, , we suggest to:
1) Extract and reinsert the MICRO (see Fig.5) from the socket, making sure that all pins are
straights and not bents.
2) Replace the 4MHz .
C) If the problem is still not solved, we suggest to
replace it (see paragraph 1.4).

switched
2.1 If the scoreboard displays correctly the information on the LED frontal, but the LCD display of
the console stays completely or partially off, this last one has to be replaced.
You should order the following article:
Art.0381-4100 - LCD Display for PS-x, 2x20 characters
The instructions for replacement are provided together with the LCD display.

3.0 A single segment of a LED digit does not light up
3.1 When a single segment of a LED does not light up, the cause is very likely because one of
the 4 LEDs that makes up the segment, is failed. Since the LEDs are connected in a series, if one of
them has a fault, this will interrupt the current in all the other LEDs.
For technicians who want to try to repair the LED electronic board, please see paragraph 3.2.
To order a new LED electronic board, please see 7.2.
3.2 Often, the LED has no faults, but the problem is due to a contact of one of the 4 LEDs of
the segment, which has a defective soldering. If is not possible to see the defective soldering, we
suggest to review with a soldering iron all the 8 solderings (2 for each LED). The defective LED can
be found out, also, by short circuiting its 2 contacts: in this case the other 3 LEDs of the series will
turn on.

4.1 If, on the LED frontal, there are several segments of LED which stay switched off or which are
lighting up incorrectly, we suggest to make a test of all LEDs visualizations.
To test the LEDs, see chapter 8.
4.2 By the Rows Test, check if all LEDs of each letter (for example all LEDs identified by the letter
) . If there are some wrong , that is, if LEDs
light up at the same time, or if some LEDs of the selected letter stay switched off, you should verify
if have been carried out properly, (see
paragraph 7.3).
If the are in the correct position, please contact the supplier indicating:
1. The scoreboard model.
2. For each LED board which does not display the correct information, please indicate the number
identifying the board, and the letters which do not light up properly, or which stay switched off even
when they should turn on.

7.2 Order of an electronic LED board
There are 2 ways to order :
1. Specify only the article code, shown on paragraph 7.1.
In this case you need a soldering iron, in order to carry out
, as specified on paragraph 7.3.
2. T
number that defines the position of the :
-- Find the scoreboard model, among those shown in chapter 9.
-- Find the number indicated for the concerned electronic board.
For example concerning the PS-M model, to order the LED board which stays in the position of
seconds units, you should specify:
art. 0430-1262/PS-M/20
7.3 Electronic LED board position
he same model of electronic LED board can be used in different positions o
, but each position requires a different setting, realized through

The chapter 9 shows the electronic LED boards for all models of the PS series
scoreboards.
Please look at the model you are interested in and note that

8.0 Test of LEDs visualizations
8.1 Preface to the Test of LEDs
Find the score model among those shown in Chapter 9. Please note that each group of 4
LEDs (segment of digit or light point) is identified by one of these letters: A, B, C, D, E, F, G, H.
You can make 3 different types of tests:
1. Rows Test . Useful to turn on all the groups of LEDs identified by the same letter.
2. Columns Test. a digit at a time.
3. Total Test.
8.2 To access the function of LEDs test:
1. Turn on the scoreboard.
2. Press the [PROG IN-OUT] key continuously . On the console display will appear
the text: Language, Lingua, Langue, etc.
3. To enter the Test press once the [NEXT] key. All groups of 4 LEDs identified by the letter
"A" have to turn on. Then, by pressing the [+] key, the LEDs of letter B" will turn on; by pressing
continuosly the [+] key, also the LEDs identified by letters C, D, E, F, G, H, will turn on. Use the
[-] key, to return to the previous visualizations.
4. press the [NEXT] key again. Use the [+] and [-] keys to turn on
the different digits. Together with a digit can be turned on also a light with the letter H.
5. the t [NEXT] . ALL LEDs have to turn on. This test,
useful for checking that there are no LEDs turned off, is not able to identify any troubles of wrong
lightings.
