my bn5 binoculars recently stopped working but i think it is because the on button is a little loose and a wire or wires may have been twisted and disconnected. my second problem is i cant completely reverse engineer and remove the optics so that i can get to the wiring or power source. i can only remove the outer structure but i have come to a standstill because i cant remove the inner structure. i don't know what tool to use or if it can be removed because i see loctite in some areas. please help.
