No Coin-up
No Lamps (Continued)
Stuck Segment
4. If voltage is not present, trace the wiring back to the terminal strips
located behind the power supply using a digital voltmeter.
5. If voltage is present but lamps do not work, install a new lamp
holder.
1. Check wiring from the coin switches to the I.O. board connector
CN 8.
2. Manually short ground pin to the center pin of connector CN 8
on the I.O. board using a small metal screwdriver and check for
coin-up.
3. If the dart board can be manually coined-up at the I.O. board, the
problem is the wiring or the coin switches.
4. If the dart board cannot be coined-up at the I.O. board, the
I.O. board may need to be replaced.
1. Unplug the ribbon cable from the target interface board. If the
stuck segment error message goes away, the problem is in the
dart head assembly.
If the problem is in the dart head assembly, first remove and
clean the rubber and matrix and remove all tips from behind the
rubber as well as in and around the target segments
The rubber may need to be replaced if it is severely indented
The matrix may need to be replaced if the problem still exists
2. Unplugging the ribbon cable from the target interface board does
not eliminate the stuck segment error message, re-install ribbon
cable into the target interface board and remove the other end
from the I.O. board located inside the upper cabinet.
If the problem goes away, the ribbon cable may need to be
replaced
If the problem does not go away, the target interface board may
need to be replaced
