If the Mijia Air Conditioner Pro Eco 2.6 kW remote control does not display, follow these steps:
1. Begin by checking the batteries by removing the battery cover and ensuring they are properly inserted. If the batteries are old or depleted, replace them with new ones, as weak batteries are one of the most common causes of display issues;
2. Next, try pressing the power button to see if the display responds. The remote control can appear unresponsive simply because it was not powered on properly. If the display lights up or returns to normal after pressing the button, the issue would be temporary;
3. If the remote control still does not display correctly after replacing the batteries and attempting to power it on, please contact the official after-sales service. A technician will be needed to inspect or replace the remote.
