TH+ won’t power up

[james Jeong]

I failed the calibration. Typhoon H + does not turn on. What should I do? Did Typhoon H + get locked?

The compass calibration?

The aircraft won’t power on?

Pull battery, reinsert, hold power button in until you get the rising tones.

 

[james Jeong]

Yes. Compass calibration failed.

Sorry. The power will not turn off. And the folding arm LED does not turn on.

 

[DoomMeister]

I assume you pulled the battery.

Does the aircraft power on as soon as you insert the battery after removal?

If it does it sounds like the on/off button switch may be stuck in and does not retract. You may need to remove the top cover to gain access to the switch to check it.

When you pull the battery, the power turns off.

Then, insert the battery again and press the power button to turn on the power.

However, the power will not turn off even if I press and hold the power button. Pull the battery back to turn it off.
