ok I bought a used Legacy 5" LCD (model: LSC5) and i have a problem. There is only 1 plug on the whole unit! There is no power input connector or RCA A/V inputs, but there is a female plug that comes out of the unit that looks like a PS/2 connector, in fact, a PS/2 plug fits in it. I have read that this has the ability for composite video and audio input and it has a built in speaker. Anyways I opened up the unit and found that the PS/2 like connector acually has only 4 wires in it (or at least that is all that connects to the pcb) There is an Orange, Yellow, Black, and Red in that order. Is it possible that all of the inputs, both power and a/v source come through this one connector? please help!!!

thanks

Common ground, power, video, sound (mono).
For all I know, it might work.

well I figured the same, but how would those 4 wires spread out to a ps/2 connector with 6 pins and a center?

any other ideas?

and any idea of how i can figure out which wires are which?

Well, either not all the pins are connected, or the same wire (probably the black one, black is often ground) is connected to more than one. And isn't the central pin in PS/2 nonconductive?

The usual method is a few pices of wire, a battery and a lightbulb :)

i figured the same, although i really dont want to fry the signal input by juicing it with 12volts....

is there a "safer" way?

Not really, except for using a 1.5V battery.
 
i thought that my best chance was the red wire as the power since its isolated by the black on the end, do u think that is the best chance too?

Might be. For all we know they might have chosen the same color coding as PSUs, red being +5V. (Wouldn't bet on it, of course)
