Try doing onboard magnetic calibration. It helped in my case

Bernardo, I switched cables, not the problem. The power is from my big tower, and is main-board power-it's fine too.

When it works there's a lot of light activity that I don't understand. I hate not understanding. I need to educate myself. Can someone point me to a manual that explains such things?I've looked, and the PX4 manual does not speak about pixhawk-specific things.

@ James Miller: Perhaps the power of the USB is too low. Try connect the Pixhawk with a short cable direct to an USB plug (?) or try a different cable

Pixhawk---DOA?
If I plug in a battery to the (connected) power monitor the pixhawk will light up one time out of 3. If I plug in the USB port to my PC, to a full-service port using the cable that came with it, my pixhawk does not light at all-- just a faint flicker from the power lights, and then a tiny tick-tick-tick-tick noise, just audible, from the FC.
If I keep trying and finally get it to light off with battery, I am able to load Qgroundcontrol, but not flash firmware. It says to unplug battery.
Help!
Anyone had this problem before? It's been in my drawer for 6 months, so HK sure aint gonna want to see it back!

Hello,

I have a Pixhawk PX4 Flight Controller and I want to use it with the PHANTOM 3 PRO  4K Camera https://hobbyking.com/en_us/phantom-3-accessory-spare-part-4k-camer.... Can you help me to connect this camera to my pixhawk and get it worked.

Best regards

@C K:

You should try uploading the firmware again and see if, maybe, your vehicle is DISARMED when the blue lights are blinking.

For further understanding of your problem you could attach your DATA LOGS and someone could take a look into it.

Regards.

@Chris: Blue light at Pixhawk means it is not locked to satellites but blue light at GPS means it is locked to satellites.

@Esteban: Yes I checked the light's meanings before. Unfortunately the issue is not that apperant to solve.

I started to think that there is a hardware issue. I made tens of different trials and couldn't solve the problem.
