Well I got an m3 real cart a little while ago and it was defective, so it blew a fuse and i opened my ds to re solder my fuse thanks to a guide on this website, but putting it back together I must have not lined up the internal and external power switch. So it snapped off.... It still works if I put a needle into the the power switch, but I was wondering if I could somehow replace this, and how difficult it would be getting the parts and replacing. Any help will be greatly appreciated,
