Wiring a LCD screen to a Wii Answered

I would like some help on learning how to wire this 7" screen that i took off of a dvd player and wire it to the Nintendo Wii. I'll show you some pictures and hopefully someone can help me out. This is what im planning if you can't tell aready, i am going to take this LCD screen and wire it up to the wii and make my own version of the wii laptop but i need help with the wiring.

Ok well i cant the the picture to let me make notes in them so ill just explain them like this going left to right.
The first picture shows what the motherboard of the dvd player said about the wiring going TO the LCD screen
The second picture is about the connector to the lcd screen, its just there for in case someone wanted to see it
The third picture is the whole lcd screen
The Forth is the wii, and here is a website for the av pinouts. http://nfggames.com/wiki/doku.php?id=av:wii_multi_av_pinout
any help?


Post an instructable!

what about a small watch sized hud(heads up display) on the wiimote, over the speaker area?

What would it display? Also spread the word that im writing up a tut for how to do my Wii Slot light mod.

like-- some gaming keyboards... have it to display quick info about the game, stats,... and in this case maybe battery level, volume, settings, and more a certain key combination on the wiimote can switch the controls between the console and hud and whats the wii slot?

wouldnt it be a "Wii-top"?

alright i have everything under control now, everything works perfectly. Thank you Viron for all your help

It looks like you just need 9 volts and composite or S-video to run the LCD, which is much easier than a laptop screen. You can regulate down the 12V from the game, with a LM7809 (or 7808 or 7810, I'd guess maybe ok too). GND is the negative of the 9 volts power. Y is one of the S-video pins C is another of the S-video pins I see a tiny dot of solder marked Video IN/OUT in the picture which should accept composite video, which is an ordinary output on many video sources such as cameras, DVD players, and VCR's.. I don't know if that's enough info to light up the screen's backlight, but if you don't blow it then it should be easy to run that LCD.

you are a god to me, i put power to it and then i put an AV cord into the Y and top Control and i get picture, although its fuzzy and fades in and out, should i try a s-video cable and what can i do to stablize the picture?

It shouldn't be fuzzy and fading in and out. Sounds like a loose or wrong connection... Is the outside of the video COAX connected to GND? I don't know what you mean by "top control" but it doesn't sound right. An s-video cable might only help if there was a connector on the screen board. It's just a wire, no magic in it.

Thank you, i was able to get the screen to have a nice crisp [picture but while im still doing test i cant get it get the crisp rich picture back i have to much fuzz. But i thank you for pointing me in the right way.

Oh, the control wire might turn othe screen on and off or something. Try connecting that to GND too, or leave it alone if that turns it off.

thank you but im using regular video out, no S-video, how would i wire up the video output to it? and thank you.

If that VIDEO IN-OUT dot is on the screen board then it should be connected to the inner wire of the coax. If it's not on the screen board then try connecting the inner wire of the coax to both Y and C. And anyway the outer wire of the coax goes to GND. You should get a nice picture, at least I did when I hacked on a LCD screen for gamecubes that had s-video input.

why dont you just hook up the wii to a tv?

i am going to take this LCD screen and wire it up to the wii and make my own version of the wii laptop

Surprising what you find if you read the post :P

yes it did have it, but i blow the pcb of the dvd player so i cant use it.

Did the DVD player you took it from have an input for video (so you could use it as a monitor)? If it did you could do a lot worse than just using the original board and solder the lead in from the Wii to the controller board for the DVD player.

Thank you ill try it, the how do doesnt go deep into the wiring of the screen and mine is different. I emailed ben and never got a response back so ill try the fourms.

Have you tried looking at Ben Heck's Forums?

They have lots of help for problems and issues just like this. Or you could try just following the wii laptop how-to on engadget.
