Diagnosis: Lights or Display Not Working
The unit otherwise operates, but lamps, meters, or the display do not work.
Safe first checks
- Confirm the dimmer or display switch is not set to off.
- Check the service documentation for lamp type before ordering replacements.
- Do not replace lamps with a different voltage or wattage.
- If several indicators failed together, treat it as a power-supply issue rather than a simple lamp issue.
Bench Technician Steps
This is the model of work a qualified electronics technician follows using the exact service manual and suitable test equipment. It is not a do-it-yourself instruction to work on energized equipment.
- Use the exact model documentation to identify the lamp, display, meter, or supply circuit involved before ordering replacements.
- Determine whether the failure is isolated to one lamp or display element, or whether multiple indicators share a supply fault.
- Match voltage, current, physical fit, and heat characteristics for any replacement component.
