Dji Phantom 3 Advanced Not Linking to remote

[dansass]

Hello everybody I got a used phantom 3 advanced and changed the main board and flown it many many times now without an issue. that was until yesterday i had my first crash. one prop was a bit broken then when i tried to take off it flipped and rattled around a bit on its side on ice for couple seconds. Now it does not want to seem to connect to my remote anymore. see attached video. I really hope that my ofdm module is not bad. the led on the ofdm module is solid red when remote is off and as soon as i turn it on, it blinks red and green.. so its getting some signal but maybe not the right data? Is there anything i can check? https://youtu.be/ykQw64JQ-io
