                Try to reprogram again the atmega 328. Verify connections to display and power supply for display. If i remember correctly first start after programming you need to push ok button when you see letters, if not, will disappear, too much/less contrast.

                          • Did you shield the coil? Do you have any pictures of your plate and coil?
