How to Fix / Troubleshooting
Safety first: Unplug the unit before inspection.
- 1. Power reset: Unplug for 10 minutes, then plug back in to see if the display recovers.
- 2. Check for moisture: Inspect the display window for condensation. If present, dry the exterior and allow the unit to sit unplugged for several hours.
- 3. Use remote/app: If available, use the remote or app to control the unit while the display is out. This confirms that only the display is affected.
- 4. Professional repair: A blank display with normal operation usually indicates a failed display board or connector, which must be replaced by a technician.
