hey

i got a goTech 7"tv that has a 3.5mm av in jack. i have the the wire that fits it and converts to a regular av plug. but for some it doesn't work. i tryed hooking it up to my vcr, and i trying hooking it up to my security camera. and nothing come on the screen when i plug them in.there is differnet tune settings- ntsc358, secam, and ntsc443. the tv is brand new, so its not the tv,

any idea??

ok i just tryed it with my dvd player and it worked fine.


why wouldn't work hooked up to my security cam??
