ok so im installing a 7" lcd in the top of my xbox, and im using a hitatchi screen (TX18D11VM1CAA)
that is connected to a Shinhwa Movidic circut board. i don't know if that helps but maybe you guys could help me search for answers... so heres the real problem from the circut board. there is a cable that used to connect it to the in-car dvd player that the screen and circut board came with. the dvd player was a saintsview. my camera is not working so a drew you a pretty picture.



the circular end was what plugged in to the dvd player. (by the way the circular end is male) so the red prong is actually pushed down into the plug. like it is not being used. but i showed it anyway.... and the rectangular one is being plugged into the circut board... all the wires are actual colors and order


i really hope you guys can help... anything would be a start

i just read my post and i realized i didn't ask my question..


if this is my wire. how do i connect it to the xbox motherboard to get video to the lcd...

what do all these wires do...


please any response would be reassuring... even if im not asking the right questions... just respond please.

It looks kinda' like it might be an UART mini-DIN 8-pin connector.

[alemerson]

Yes it is an 8-pin mini-din.. i just looked and thats it.... now the question is what does that mean... are the pins that connect to either side just act like wires? like are any of the pins pre-defined as a certain function...  and what about the other side, that connects to the circut board.. how do i go about figuring out what they do


by the way, thanks alot Mr Ed.. its a start

well i think you need to look up teh specs of the dvd player and see in what format it outputs teh video. being 8-pin, id think its in red-green-blue configuration (dont know what they call it), but its one (or two) wires for each colour.

[alemerson]

i don't exactly know what you mean... i have looked at the specs, but im not quite sure what im looking at. what category would it be under. like what would the spec be labeled.

Edit: okay so it says    VIDEO OUTPUT: NTSC


and by the way... the screen only recieves power through the dvd player. so maybe one of the wires is for power.... it says it runs on 12v so im pretty sure i could tap into something

it also says that the video output is RCA... i don't know if this helps..


im kinda totally relying on you guys so thanks for helping so far, any more info would be greatly appreciated.

if you have to dvd player still you should find out first off which pin is ground and which is the 12v(+).

[Jameson42]

I'm going to venture a big educated guess here on what each color is for... yellow is most likely 12V positive, the black next to it the 12v ground.  the red, green, and blue wires are prolly Pr+, Y+, and Pb+ respectively (component video).  The black next to those would be the common ground for the three.  I have no idea what the brown would be.

Look for JaredC01's thread for info on finding the component connections on the xbox motherboard.  

I make no guarantees that I'm right... the only thing that'll fuck up the screen is if you connect the 12v stuff to the wrong place... but then again, all the colors of wires in your connector are fairly standard a/v and power colors, so I doubt my proposed connections would mess anything up.

it's possible that the lcd wants a VGA signal instead of a component video signal... in which case red, green, and blue are the RGB of VGA, and the black and brown would be vertical and horizontal sync signals (don't know which would be which...).  The big black would then be a common ground for everything.  For VGA connection help, look in the tutorials, or look through the links in my sig.  Try component first, cause vga is a lot more work on the xbox.

Jameson seems to know what hes talking about, but keep in mind that his colours were a guess, but also as he said, it shouldn't harm anything in trying, other than connecting 12v to the wrong spot.

There are tuts around for installing LCD screens, theres one under the case modding FAQ under the case modding section. I have tried but don't understand all of it.

Does ur screen have a headphone jack or audio output on it? Cos if so, that may take 2-3 wires, and just use 1-2 for video (composite) or if it uses ygb (i think its called that, the red/green/blue) hi def plugs then it may need more effort. You'd just have to find out which is which then solder each one to the right pin on the underside of the AV connector on the mobo.

[Jameson42]

Did a little research on the TX18D11VM1CAA, and Shinhwa Movidic.
I'm guessing this is your screen...

While the Shinhwa Movidic device uses 12V DC, the Hitachi screen uses only 3.3V... but good luck finding something other than the Shinhwa Movidic board to provide 18 bit digital RGB to the Hitachi screen. 800x480 pixels seems a little odd to me...

I couldn't find any more info on the wiring, but I'm thinking from the info in the above link that the input is standard composite video... a.k.a. the video on the standard xbox a/v cable.

If you can get to a scanner, please scan the specs pages out of the manual.  Any info you can provide to me gives me more ability to help you.

i still have the dvd player. how would i go about finding which pin is the gound?

the sceen itself has a headphone jack, an ir reciever for the remote control, and buttons ( SEL UP, SEL DOWN, MENU, and POWER), maybe that acounts for some wires...

i can scan it but im pretty sure i could just tell you what it says:

Display type: TFT LCD panel
Resolution: 800(H) x RGB x 480(V)
Composite Video: 1Vpp (75 ohm), RCA JACK
Video Input: 1Vpp 47 ohm unbalanced, RCA JACK

now the last two could be for the DVD player itself, it does't specify what the specs are for (by the way, these aren't all the specs, just the ones i thought were important)


thanks so much everyone, for your help, i would be eternally greatful if we could get this working.

If I were you, I'd just take the pcb out of my dvd player and hook everything up the way it was meant to be minus the dvd drive. This way you'd have the proper power conversion and rca inputs. If the board is small enough you might possible be able to attach it to the bottom of the xbox dvd drive, solder the composite leads from the xbox output to the input of your dvd player's pcb. Then simply mount your screen however you choose. To me, this seems most logical. I don't think you'll ever get just the xbox and screen to work together. I think you need that pcb AND it makes this much simpler provided you can find a place for that pcb, but it's can't be too large if the dvd player was intended to be mounted in a DIN location in your dash.

[alemerson]

okay... so i took out the pcb board. and i plugged plugged the pcb board to the screen and its board. i see avalaunch!!!!!! and the pcb has rca plugs on it (thats where i plugged my xbox into...
the only problem is, is in dissassebling the screen i broke the tab that connects the video to the screen. its really thin ribbon wire, its blue and white, and you need to push in a little tab to secure it. so as of now im just holding it in with my thumb, (<- doesn't work so well) the pcb board is a little bigger than the dvd drive, so im going to see if i can make it work.


do you guys think that that is the best way, or can it be done without the dvd pcb board?


thanks so far

well have a look on the board. if the signal goes to any ic's, then id bet no, you need the board
