H520E RTK drone – problem with switching on

[aerodron]

I have two problems with the drone, as described in the title.
1. The RTK antenna is detached from the upper casing. Can it be repaired somehow, or does the entire upper casing, including the antenna cable, need to be replaced?
2. The drone does not want to ‘start up’ when I press the power button, and when I release it, it turns off immediately. However, when I hold it down, there is no problem with the camera connection, which calibrates normally, but as soon as I release the power button, it immediately turns off. I replaced the power switch, but it did not help. How can I fix this?
I am attaching photos of the motherboard and the torn antenna. Thank you for your repair tips.

Hello. If I have a motherboard from H520 E and the motherboard from H520E RTK is damaged, is it sufficient to just install different software when replacing it, or is there another method required? Thank you for your assistance.

I am uncertain if there is a difference in the motherboard. And I can't see where the antenna is connected from your pictures.
I hope that @WTFDproject can help with the on/off problem.

The difference between the H520E and the H520E-RTK is only in the hardware.
The firmware/software is the same as for the H520E.

Thank you for the information. Tomorrow I will replace the board because the problem must be with the board, as the drone flew in the rain and unfortunately it is not possible to turn it on without physically holding down the ON/OFF button all the time, so that must be the cause of the problem. I will let you know if replacing the board helped, because it cannot be a software fault.

Here is another example of one that few in the rain

Everything went well, the drone is theoretically working, but I am concerned about messages like the ones in the photos. What do these messages mean? (I will test the drone in the air tomorrow).

You won't be able to get the drone airborne... I wouldn't even try unless you have GPS. Is the GPS module connected? What does the menu show under "Sensors"? The NFZ message is related to the missing GPS. The fact that the drone cannot set a home point is also related to this. Don't take this error message lightly.

The no fly zone status no unlock I got after updating to latest software, are u running all the latest. Also u will get the bug where arms 1 and 6 will blink green no mater what mode ur in, angle , return to home and what ever the 3rd one is called on the h520e. U will also get a message to add ur flyer id . Pretty sure enrico is correct here with it being related to gps. Unfortunately the trigger for the message should come after gps is established if close by or in a no fly zone but it comes before. Pretty easy to forget to re connect the gps wires if u removed the top shell as without disconnecting it the top shell will hang there by that one wire. See is that connected by removing the top shell again and ignore the no fly zone status and flyer if message. If u go back a version on the software u won’t get them messages but definitely investigate the gps like enrico says .

Also I don’t know why the no fly zone status comes up as a critical warning message, if my understanding is correct it’s an info message to the pilot to be aware of no fly zones. I took the h520e directly into the centre of a no fly zone and it still armed and would probably fly but obviously wasn’t going to fly there.

Sorry, but I forgot to add that the drone is in ‘indoor’ mode because it is indoors, so I put the propellers on it to turn on only the motors, but unfortunately it did not turn on and I only got these messages. Is this normal indoors?

I’m pretty certain I’ve seen this exact same issue where it wouldn’t arm on indoor mode. Perhaps try deleting all the warning messages, make sure it on angle mode. The blinking arms 1 and 6 are going to be annoying now for this stage as u can’t tell when all is ready to go as the lights never change to a solid colour. Quickest test is to bring it outside and turn off indoor mode, let gps establish and see will it arm then. If we establish that’s all working correctly we can then work out the not arming in indoor mode when we know no other faults are present. Ill try the indoor mode myself tomorrow if u haven’t had any success to see do I get the same result as u with not arming. It’s nearly 1am here now and trying to figure out what to do with the **** elf on the shelf to amuse the kids when they wake , there was none of these elf’s about when we were kids, if u know u know , chat 2moro
