Start, Select and Homebutton suddenly wont work on Arcade Stick

Hey guys,

following problem:
I changed the stick in my arcade stick this week and everything worked fine. But i forgett to attach the ball on the stick so i opened it again. But since then my start, select and homebutton doesnt work anymore. I had opened the case to see if a cable is loose but everything seems fine inside the case.
Has anybody an idea what i can do to find out where the problem is?

only thing i can think is to make sure the lock isn’t engaged.

Do you have the TE “S” HeaD?
I would think then that the Lock Switch is on.

Hm, ok guys, it was the switch…>_< i already forgott that i have this switch…thats so fucking embarrassing for me…^^
