Super Action Controller Keypad

[sgtdave]

I completely took apart one of my SACs, cleaned every contact and connector. I still cannot get any keypad buttons to function. I have two controllers, and not one working keypad button between them.

 

I know the commonality of broken SACs has been brought up before. But has anyone actually successfully repaired the keypad on their Super Action Controller? If so, could you share what you did to fix it?

 

Thanks,
