L and R buttons not working.
I have had this SNES controller for a long time that's L-button is not working. So I took it apart today, cleaned all the parts and put it back together. But now the R-button doesn't work either! So all the other buttons work great, except L and R buttons. I have no idea what the problem is. I used a multimeter to determine that current gets through the connection when button is being pressed. I see no visible damage to the circuit board or wiring inside the controller. Is there anything I can do to fix this?
Es esta una buena pregunta?
