Step 1: Make sure that the insulating insert in the battery compartment of the remote controller has been taken out (some battery compartments of the remote controller have no insulating insert);

Step 2: Load the battery that is given at random, and be sure not to install the positive and negative electrodes upside down (the smooth and flat side of the battery, marked with a big+sign, is the positive electrode, which should be upward);

Step 3, test whether the remote controller is powered on: there is an LED indicator near the power-on key on the left side of the remote controller, and press the "Volume+"and "Volume-"keys of the remote controller at the same time. If the light is red, it indicates that the remote controller itself is powered on and the battery is not installed backwards;

Step 4, after lighting the LED indicator of the remote controller according to the previous step, the state of the light is always on at first, then it will start flashing, and then it will go out again after flashing for a while;

Step 5, unplug the power supply of the Tmall Box;

Step 6: Press the "Volume+"and "Volume-"buttons on the remote control at the same time again, and the LED will light up red (always on). Don't let go to keep this state, and plug in the power of Tmall's box at the same time (this step may need help from others. Of course, people with extremely fast hands may also succeed);

Step 7, after the Tmall Box is powered on, release the two buttons of the remote controller as soon as the startup picture of the Box appears on the TV screen;

Step 8, the red light of the remote controller LED flashes, and code alignment begins. If the code alignment is successful, the red light will go out after only a few flashes.

Ok, after the above steps, the problem of no response/failure of the remote control of Tmall Box can be solved.
