Composite video LCD screen question

[Betty_Swallocks]

I've just been given a 4" LCD composite video screen which I would like to use with the TV output of my graphics card.
I know this will drive the screen but I can't find any kind of manual or details of the screen other than that in the link.

The problem I have is the connections. There are four wires going into the unit. Two black ones which I presume are ground, a white one and a red one.
I think it is safe to assume that the other two are the 12v power supply and the composite video input.
But which is which?

I don't want to just connect it up and hope. I'm reasonably certain that putting 12v down the composite video input would be likely to be a "Very Bad Idea™"

Anybody got any knowledge of this?

What sort of connections/wires are they?

If they are RCA/phono, red and white are usually audio..

Power shouldnt be a phono connection, instead either a DC jack, or a kettle lead, or the moulded 8 plug type thing. Chances are its a dc jack, as theres not usually enough space for a full PSU, although regulation will be in there ...

Just saw the pic you linked too.. not sure.. the red and black shown look like the CCFL backlight connectors, but there usually combined into one..

Can you get a better pic?

It's OK thanks. I've found the info. The black ones are ground as I suspected. The red is the +12v and the white is the composite video input.

(They're just bare wires, btw)
