is the monitor ruined?

while hooking up a pair of monitors (power acoustik) to a dvd player; a live 12volt wire came into contact with one of the rca video inputs that went into one of the monitors (each monitor has its own junction box; one for the infared and one just normal). the monitor blanked to a blue screen and said no input. before this happened both were working fine and now only the one works. is the monitor ruined??? i am having the company send me a new junction box and i am hoping that that is causing the no signal.any help would be greatly appreciated

i dont see it being ruined i dnt know how it could be. the voltage that hit the rca and crisped the junction box it should work.. post if it doesnt

nope just toasted the junction box. i hooked up and everything was good.
