There are two kinds of damage to electronic equipment: aging (slow degradation of performance to damage) and hard damage (sudden damage to equipment). Aging is common in all electronic mechanical and electrical equipment, and generally does not cause damage-unless the equipment with quality problems will fail due to aging, because the aging factor of the equipment has been considered in the design. Hard damage is the sudden damage of devices, and it is also the main factor of electronic and electrical damage-especially in the aging process of new products, hard damage of devices is more likely to occur.

Specific repair methods can try the following operations:

1, try changing the battery first;

2. If it doesn't work, take down the battery, blow the remote control button and battery hole with a hair dryer a few times, and then press all the buttons a few times to prevent the buttons from hardening and failing in cold weather;

3. Turn on the remote control, erase the contact position and try again;
