Start button doesn't work on my SE

i got the madcatz SE 2 months ago and the start button stopped working. is there anyway to fix this or replace the button?

thanks but its not the same problem. whenever i open the SE and switch the wiring for “start” and “back” button and plug it back in, it’ll start working for a while and goes back to not working.
