Maintenance & 3-3
Troubleshooting
• Internal lamp driver malfunction.
Digit will not light. • Fuse blown in driver.
• Black wire to the digit is broken.
• Poor contact at driver connector.
Segment will not light. • Lamps are burned out.
• Driver malfunction (bad triac).
• Broken wire between lamp driver and digit.
• Poor contact at driver connector.
Segment stays lit. • Driver malfunction (bad triac).
• Broken wire behind digit
If a problem is observed in one digit, the cause may be isolated by swapping plugs on the
driver (connect the plug from the digit into a different jack). If the same digit shows the same
problem, the cause may be in the digit or the wiring. If the problem moves to another digit,
then the cause is probably an internal driver problem.
Use a volt meter at driver inputs to determine if power is being supplied to the driver. An
ohmmeter can be helpful in finding broken wires and bad connections. Internal electronic
problems must be corrected by Daktronics or by an authorized service center.
