I have read through most of the DIY projector posts (yeah 100's of pages worth)
While looking through some of the links I remembered I had a small LCD monitor that I never could get to work. Back when I got it I did not know much about how they work, the problem has been that the ends were cut, i could see that it has a positive in red, a negative in black and a yellow which i assumed was video in. I hooked it up to a dc inverter and wahlah it powered up. Now I could never figure out how ti get video into the thing.
While reading through the LCD projector stuff I took a link and saw my monitor!!! GREAT I'm thinking I have a 5.6 TFT color monitor that has been connected to the project in more than a few posts! Now here is the first problem.
1 http://img10.exs.cx/my.php?loc=img10&image=cutwires.jpg
The wires are cut, i can make it take negative and positive 12v power to get it to turn on but can someone help me with getting the thing to take a video signal. What was the original video in for this monitor? Will I be able to go to radio shack and simply find s video or rf connectors that will allow this to hook up to a
tv out card from a computer, or can someone tell me how i can use it as a car tv monitor?
here is a pic of the monitor outside of the casing
http://img10.exs.cx/my.php?loc=img10&image=monitoroutofcasewithcontrollerboard.jpg
from what I am to understand once i can get a video signal into this monitor I need to take the back off this
http://img10.exs.cx/my.php?loc=img10&image=monitor.jpg
and connect it back to the control board in the other pic, then extend the wires from the control board to the lcd panel which should now be translucent
Then I need to pass light through it, make the picture it makes bigger and then shine it on the wall?
Coincidently I used to work as head sales for a computer/survalence place and have a box of some random LCD monitors for some random laptop. I will check to see if i can get the backlighting off this without running into the ribbon cable problem....... Can someone link me to someone who actually got this all done, all the links look like the posts were from 2001-2002, it is now 2004, someone should have done it by now.......

i cannot be certain of what type of input wires they are cause you pictures are not of the highest quality, but judging from the fact that there is a red, black, and yellow wire, id say they are rca wires. you can pick up a plug end here

The thing is it only has those 3 sperate lines running into it all encased in one line.
It would really help if I knew what the factory ends of this encased line looked like. I brought it to Radio Shack about an hour ago and they had no idea how to deal with it. It is not that the guy did not know his ****, we talked for a while and he knew what he was talking about and I know 12v electronics decently but the problem is this.
There is one red encased aluminum line, one unshielded aluminum line and a shielded yellow line. If you hook the red line up to a + 12v source and then the unshielded aluminium line to the - it will power on and show a white screen. There is no audio on this monitor it is only video but the yellow line runs to the same input source as the aluminum and red lines. The guy was saying that the unshielded may not necessarily be ground, but that there really is nothing else for it to be because there is no chasis ground on the control board. He is most worried about powering it wrong and having a closed loop burn the liquid crystals out and blow the monitor. Simply he does not think that the yellow line is simply video in but sometimes people make things more complicated than they need be.......
So what I am going to do is get the RCA end and wire it to the yellow line and see if it will accept a video signal.
Can someone show me the factory ends of their dc powered 5.6 monitors so i can get an idea of how these factory ends should have looked? All the monitors I deal with in 12v car have jacks on the monitor, they do not have a line running from the monitor so I nor the guys at the Shack know for sure what is going on here, since this is a hard wired monitor it looks like. The RCA is just a shot in the dark, i do not really care to much about this monitor, I already have a 7 on the way for my projector but I do not like to be beaten on things like this so any help would be appreciated.

It would be helpful if you would post the make and model number of the unit. Maybe someone here has one or knows about it.
Number plate on back says
Model #7861
TFT color monitor
14.5cm (5.6) DC12v 0.5A
It is a NEC monitor but the casing on the outside did not say NEC, In one of the links in a thread I saw one displayed but now I can not find it 🙁

Just got back from Walmart where I bought a RCA Y cable and cut one end off and found out something interesting.
A RCA cable is comprised of Copper wire running the length of a shielded length of more copper wire, the ones on the outside run to the metal casing on the outside and the ones in the internal shielded length run to the prong or cyclinder in the middle depending on if the end is male or female.
My yellow line on this monitor does not have the same set up, it is just bundle of aluminum wire inside of a insulator, this leads me to believe that all 3 of these lines run to some type of module/controller and that module has negative/positive/video in. I am hoping someone else has a monitor with a simular set up and that the modules are pretty universal if not this thing is good for absolutely nothing.

Hopefully you will find the link where you saw it to find out the brand name of the monitor. NEC made that monitor for some company and that company is your best bet for any information on it.

that is it in the upper right hand corner but now I see it actually only says TFT color monitor on it.......
Does anyone know if there is a universal module/controller that I can hard wire this 5.6 to? It seems to me now that this monitor HAS to be wired to something that "decodes" the video signal for it and also plugs the 12v DC current into it or perhaps it even converts a AC current into 12v DC. If not I am just going to place an order for a 7" as there is no real way to get an answer unless someone happens to have a simular monitor and knows if there is a universal part or if they have a broken monitor and want to clip the part i need and sell it to me.

Talked to someone at NEC the monitor is a
NL3224AC35-09
I was told that I needed to find the manufacturer of the control board used on it, I just assume try to find another control board if possible, anyone have any information on how I can do this?

Is there any way that you could post a high res pic of the electronics? (maybe put the panel on a scanner) I could be completely wrong, but given that this is a 12vdc panel I think the wiring sceme would be similar to other panels for use is cars. The red and black are 12v and ground just like you thought, but the yellow line is probably used to toggle video inputs for use with a camera or backing up(I've seen several panels that are setup this way). The connections for video in are likely some where else on the board.
An externally hosted image should be here but it was not working when we last tested it.
here is a better picture of the control board. There you can see the negative and positive all go into the board at the same place and there is no where else to feed a video signal to. You can see the 30pin ribbon that feeds the 5.6 inch NEC monitor NL3224AC35-09 which NEC says was custom made for another company but did not tell me who for. They said it should be like the c35-01 and that i just need to find a compatible board.

here is the end of my 7.2 as it was shipped to me, I believe the 5.6 monitor from above has wires go to a connector that is just like this that everything gets fed into including sound on this one. I am in need of the connector for this monitor and will begin the search tomorrow. Did a google search for the numbers on the back of this monitor AM-070PN/PP-C with no results.
