Madcatz TE S Fightstick help

I had been using my TE S Fightstick for around 6 months when, all of a sudden, both the start and select buttons would not work. Its been about 2 months now and I’ve done my best to do without them but I just can’t stand having two broken buttons. I’ve opened the stick and confirmed that the wires are all connected nice and tight, but neither work. Would anyone beable to tell me what’s wrong, or even how to fix it…?

Did you lock them up?
Because the Lock Switch on TE S for Guide/Home now does Start and Back/Select also.
