DJI Drone Won’t Turn On? Common Causes and What to Do
Share
You’re ready to fly your DJI drone, press the power button, and… nothing happens. No lights, no startup sound, and no response from the drone.
A DJI drone that won’t turn on can be caused by something as simple as a discharged battery or as serious as damage to the drone’s internal power circuitry.
Before assuming your drone is beyond repair, there are several things worth checking.
1. Check the DJI Battery First
The battery is one of the most common reasons a DJI drone will not power on.
If the battery has been stored for a long period, completely discharged, exposed to extreme temperatures, or has developed an internal fault, the drone may show no signs of life.
Check whether:
- The battery LEDs illuminate when you press the battery button.
- The battery charges normally with the correct DJI charger or charging hub.
- The battery is swollen, damaged, leaking, or unusually hot.
- Another known-good compatible battery can power the drone.
If the battery is swollen or physically damaged, do not continue charging or using it.
A battery that appears completely dead may require replacement, but testing with another compatible battery can help determine whether the problem is with the battery or the drone itself.
2. Make Sure You Are Using the Correct Power-On Sequence
Many DJI drones do not turn on with one simple press of the power button.
The usual DJI power-on method is:
Press the power button once, then press it again and hold it for approximately two seconds.
If you have recently purchased the drone or have not used it for some time, it is worth checking the power-on procedure before assuming there is a hardware fault.
3. Check the Battery Connection
Even when the battery itself is working, poor electrical contact between the battery and the drone can prevent startup.
Inspect the battery compartment and connectors for:
- Dirt or debris
- Bent or damaged contacts
- Corrosion
- Signs of overheating
- Physical damage following a crash
Do not insert metal objects into the battery terminals or attempt to short or bridge any contacts.
If the battery fits loosely or the contacts appear damaged, professional inspection is recommended.
4. Has the Drone Been Crashed?
A DJI drone may look fine externally after a crash while having significant internal damage.
An impact can damage components such as:
- Battery connectors
- Internal flex cables
- Power circuits
- ESC components
- Mainboard components
- Motors and motor wiring
- Internal connectors
Sometimes a drone continues working immediately after a minor crash but develops power problems later due to a damaged connector, cracked solder joint, or component failure.
If your DJI drone stopped turning on after a crash, repeatedly attempting to power it on may not be the best approach. An internal inspection can help identify the actual fault.
5. Check for Water or Moisture Damage
Has your DJI drone recently flown in rain, landed on wet grass, fallen into water, or been exposed to significant moisture?
Liquid damage can cause corrosion or electrical shorts inside the drone.
Even if the drone initially continues working, corrosion can develop over time and eventually cause startup or power problems.
If you suspect liquid has entered the drone:
Do not keep trying to turn it on or charge it.
Remove the battery if it can be safely removed and arrange an inspection as soon as possible.
6. Battery Charges but the Drone Still Won’t Turn On
If the battery appears to charge normally and its LEDs work, but the aircraft remains completely dead, the problem may be inside the drone.
Possible causes can include:
- Damaged battery connector
- Internal power supply fault
- Mainboard fault
- Damaged power circuitry
- Shorted electronic component
- Internal connector or flex cable damage
- Crash or liquid-related board damage
These problems normally require professional diagnosis because identifying the fault may involve disassembly and electronic measurements.
7. Could It Be a Firmware Problem?
Firmware issues can occasionally cause unusual startup or operational problems.
However, if the drone is completely dead with no lights or response at all, a hardware or power-related problem should also be considered.
If the drone powers on but does not initialise correctly, connect properly, or complete startup, checking the DJI app and firmware status may be worthwhile.
Avoid repeatedly interrupting firmware updates or attempting unofficial firmware modifications, as this can create additional problems.
8. Don't Forget the Controller
Sometimes the aircraft itself is working, but the problem appears to be related to the drone because the controller will not start or connect.
Check the aircraft and controller separately.
If the drone powers on normally but will not connect to the remote controller, you may be dealing with a pairing, firmware, compatibility, controller, or communication problem rather than a power fault in the aircraft.
When Should You Get Your DJI Drone Professionally Checked?
Consider professional diagnosis if:
- The DJI drone shows no signs of power with a known-good battery.
- It stopped working after a crash.
- The drone has been exposed to water or moisture.
- The battery works in another compatible drone but not yours.
- You notice damaged or burnt battery contacts.
- The drone briefly powers on and then shuts down.
- There is an unusual smell or excessive heat.
- You suspect an internal motherboard or power-circuit fault.
Continuing to power up a drone with an electrical or liquid-damage fault can sometimes cause additional damage.
Can a DJI Drone That Won’t Turn On Be Repaired?
In many cases, yes.
The repair required depends on the actual cause. A no-power DJI drone does not automatically mean the entire aircraft needs replacing.
Depending on the diagnosis, the solution may involve battery replacement, connector repair, internal component replacement, power-circuit repair, or motherboard-level repair.
A proper diagnosis is important before deciding whether repairing or replacing the drone makes more sense.

Frequently Asked Questions
Why won't my DJI drone turn on even though the battery is charged?
The problem may be related to the battery connection, internal power circuitry, mainboard, crash damage, liquid damage, or another electronic fault. Testing with a known-good compatible battery can help separate a battery problem from an aircraft problem.
Why does my DJI drone turn on and then immediately turn off?
Possible causes include a battery fault, poor battery connection, internal power problem, damaged component, or motherboard fault. Professional diagnosis may be necessary if the problem continues with a known-good battery.
Can a crashed DJI drone be repaired?
Many crashed DJI drones can be repaired. The repairability and cost depend on which components were damaged, such as the arms, motors, gimbal, camera, internal cables, ESC or mainboard.
Can a water-damaged DJI drone be repaired?
Sometimes. The outcome depends on the amount of liquid exposure and which internal components have been affected. Avoid repeatedly powering on a wet drone because this can potentially cause further electrical damage.
Should I repair or replace my DJI drone?
This depends on the model, age, extent of damage and repair cost. A professional diagnosis can help determine whether repairing the drone is economically worthwhile.
