Japanese Megadrive 2 controller socket replacement

my Japanese Megadrive2 controller 1 socket, It can't recognise well all the inputs.

I've tried to clean out everything possible and even bending a little the pins, but no luck.

Strangely, if I apply some weight on the controller plug, while it's inside the console, everything works properly...

I'm thinking I just have to ask a professionist if can do some soldering on the board, maybe for a controller ports replacement.

Could you do such a service, please?

Thanks in advance.

Bye,

P.G.
