Anyone care to help me with a mystery screen?
I recently got two headrest monitors from a friend of mine out of a car he was selling, but the problem is, neither of us can find any of the cables or documentation on how to get the damn thing to work. The only thing I can see is a 4-pin input on the side of each screen that I would assume takes in power and video signal via some adapter. There are a couple of model numbers, one under that plastic piece next to the Sharp logo which is DUNTK2547TPZZ, the other is B2391A (which you can see in the pics below). Googling both of these didn't really get me anywhere, other than verifying that it in fact is a Sharp screen.
Has anyone seen anything like this, or have any idea where to point me? Are those 4 pinouts common? Can I make an adapter to make it work?
Below are some photos...

do you have a bottom side picture of that circuit board with the 4 pin plug on it?

Looks like the half-empty board is made specifically for in-car use of that panel...
The connector probably takes +12v, ground and 2 inputs, or +12v, input and 2 ground pins.
You should trace the pins' tracks to see where they go. I see some regulators and I guess the switches are for adjusting brightness and switching between 2 inputs (but i could be very wrong here  )

There isn't much to see on the other side of the 4-pin, because there is a huge chunk of double sided tape that kept it in the housing...

I wanted to see traces, but ok, can you take a picture looking straight down onto the white 4 pin connector?

Not the best picture but it shows the grouping, the red on the end is the power, the white on the oposite end is from the pair for the video.

I don't see any red/white anywhere near the connector... or you must mean the wires coming from the inverter, going to the backlight, which certainly have nothing to do with 12v or video...

obviously my screen is not the same as yours, but those pins are probably pretty much standard. The connector is the same at least
