Monitor will not show dvd

you need to put the dvds handbrake wire to a suitable earth point and then your dvds will play fine i think the wirings colour is a yellow with a blue tracer line on the wire if its an alpine dvd player and the same is on all the monitors themselves that wire will have to be connected to a good earthing point but luckily on the monitors they have a black earth wire running to them so just splice that yellow/blue wre into the black earth wire on each headrest monitor !

what type of head unit are you using its different for each one. e.x. for alpine you cant just hook up one wire and its done, unless its just the monitors (for rear seat entertainment) if its an alpine head unit you need whats called a (TR7) made by a company called PAC. if it is the rear seat monitors from alpine, like the (tme-m710) not sure if its the same for all monitors. you need to look at the wire side of the 10 pin harness where the yellow/blue wire is the second from the top right you need to move that pin to the bottom right position then hook that wire up to ground which should be the wire in the very bottom left pin (black). that will bypass the monitor itself but if the head unit is locked it wont matter start with that first.
