Repairing a genesis controller

[Damon Plus]

I bought a six-button pad a few months ago, and it worked fine. Last week I couldn´t make it work, so I opened it and tried the contacts pushing where the buttons should go. All of them worked except A and Right. There´s no wires broken or anything. What could I do?

Is everything clean? the metal discs and the contacts on the PCB?

[Damon Plus]

Yes I´ve cleaned them with alcohol, but it doesn´t work. All of the wires seem fixed to the PCB, I don´t understand what could be the problem.

Could be a break inside the cable. You could test continuity with a meter, from the cable end holes, to the wires inside.
