Possible Causes
Loose ribbon cable between display and PCB, Damaged communication harness, Faulty display module, Faulty main PCB communication driver
How to Fix / Troubleshooting
Safety: Isolate power before removing the front panel or display module.
Steps:
- Access display: Remove the front fascia carefully to expose the display PCB and its ribbon or plug‑in connector.
- Reseat connectors: Unplug the ribbon or harness, inspect for bent pins or corrosion, then reconnect firmly.
- Check cable condition: Look for kinks, cuts, or crushed sections in the cable. Replace if damaged.
- Module swap (if available): If you have access to a known‑good display module, swap it to determine whether the fault lies with the display or main PCB.
Note: If E18 persists with a good cable and display, the main PCB is likely at fault and should be replaced.
