I found an old car DVD player, figured I might try and use the LCDs for something else, most likely with a raspberry pi. They're 4.5" displays, Prime View Model #PW045XS2. I'm thinking adding an RCA connector to the driver would be the easiest feat, the thing I'm not so confident on is the power. I found the specs for the DVD player as a whole here: http://www.diagramasde.com/diagramas/otros2/PVS1950D[1].pdf Page 16 has the monitor diagram.

I want to confirm one thing - If I just connect an RCA port to the VIDEO/VGND pins, should that work or is there something else I need to do?

And I want to ask another - What kind of power supply do I need to connect? I'm fairly sure it needs 5V, but not sure on the amperage. I did try a 5V 500mA supply (what I had lying around) and was able to get at least some of the backlight on.

The easiest thing would be to measure it while it's connected to the rest of the player. Use a multimeter to measure the supply voltage and current draw on the power connector.
