PLEASE HELP AS I HAVE BEEN OUT OF COMMISION FOR ABOUT 2 WEEKS AND WANT TO FLY

So recently I got myself a zmr quadcopter .. emax 2300 kv motors ... cc3d flight controller with devo 7 transmitter and receiver ...... I didn't like the fact that devo 7 didn't have a fail safe that worked so I purchased a dx8 transmitter with ar8000 receiver..... bound the new trans and receiver and the quad flew great and loved every minute of it ......now the cc3d flight controller was already set up so I didn't have to mess with it but sadly I broke the main connector on the cc3d so had to get a new 1 .
I installed the new cc3d and attached the receiver but the receiver won't power up on this board when it worked on the other (exactly the same board ).
So I thought I damaged the receiver somehow so went and got a brand new receiver (ar8000) but that would not power up either .
I then tried the devo 7 receiver which again still did not work.
So my question is does anyone have any ideas as to y this is not working ....maybe a bad board ?
I used open pilot and did the quad set up for the esc and motors and accelerometer which worked fine but trans set up is a no go .

Can you copy the configuration from the broken cc3d to your new one, or at least read to see settings? possibly turn voltage out on? I am not familiar with the cc3d so I am not sure what else to try.

I've only had the quad about 3 weeks and I'm new to this type of quad set up so I'm not sure how to to b honest ..... if I find out how to then I'll post and copying info sounds like a good try to me ....... I have ordered another cc3d board and also a naze 32 .....if either of those don't work with n e of the 3 receivers I have then I'm stumped lol

I just had a thought ..... b 4 I installed the new cc3d board I added 4 led strips to the pdb .... could that b using too much power causing the receiver not to work ?...... I transfered the Info from the broken board to the new 1 but still not powering up the receiver

with devo 7 transmitter and receiver ...... I didn't like the fact that devo 7 didn't have a fail safe that worked

Did you set it correctly? By default it's at 0%, which in Devo talk means center on the servo. The range is -125 to +125. Leaving it at 0% would be like having it in a hover. It's a bit confusing.

Failsafes can also be set in Open/LibrePilot, it is a tad confusing.

Yeah I did that but set it on the controller not open pilot ..... I wanted throttle to kill when I lost signal which wouldn't work but on the ar8000 it worked right away

Problem solved ..... had to rebind the trans and receiver 4 times b 4 it would sync but all is good now .... ty for the help
