you could do what I did and chop the connector off the TG pad, and wire the mini din connector in place.
hell I just twisted the wires and used tape instead of soldering it. Took like 5 minutes!
I had the same kinda problem. the buttons were getting flakey.
aside from that, getting a big female din and male mini din and hacking up an adapter aint no sweat. if you're not good at it, someone else around here will probably help out no problem
