Hrap ex broken?

ok well i bought a hrap ex (hori real arcade pro ex) when it was 1st launched in japan. and it seems i have a problem with the wire. like ill play and if the wire gets move just barely the joystick gets disconected and i get the please reconnect controller icon. so does anyone know how to fix this?

The wiring has broken somewhere along the cord (usually near where it comes out of the case). You need to find that area, cut it off, then splice/solder the wires back together.

OR

Buy a replacement cord from someone. I believe all HRAPs, including yours, uses a molex connector for the cord. Just pull out the cord and replace it with the new one. Check below link for a picture.
