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).

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).
