Possible Causes
Loose ribbon cable between main board and LCD, Failed LCD backlight driver, Damaged display module from impact, Faulty low-voltage regulator feeding display
How to Fix / Troubleshooting
Safety first: Disconnect power before opening the charger to access the display.
- 1. Check external symptoms: If the charger still charges vehicles correctly but the display is faulty, the issue is likely limited to the display subsystem.
- 2. Open front cover (if serviceable): With power off, remove the front panel screws and gently access the display board.
- 3. Reseat connectors: Carefully unplug and reinsert the ribbon cable or harness between the main control board and the display module.
- 4. Inspect for cracks: Look for visible cracks or liquid damage on the LCD. If present, replace the display module.
- 5. Replace display or main board: If reseating cables does not resolve E17, either the display module or the display driver on the main board is defective. Replace the faulty component according to Primecom parts availability.
