leads breaking at PC board.

CAUSE
Due to variations in diameter of
LEDs, some may be loose in the
holder on the assembly.
problem develops this procedure
should be completed.
MODIFICATION
A matrix ribbon cable connector
clamp has been developed to safe-

connections.
SYMPTOM
Occasionally, a dart may hit a
segment and not score.
Apparently the heavy vibration
from the Supercharger Ramp

to break the leads where they are
soldered to the PC board.
The blue edge connector on the
matrix ribbon tail may have
faulty crimps.
SOLUTION
SOLUTION
If the LED is loose in the LED
holder, it may help to glue the
LED to the holder. Since we have
only had this happen a couple of
times, this is just an "early warn-

All matrix boards prior to the
date code "9123" should be modi-
fied to prevent future problems.
