Question Why is my Wii's video output extremely fuzzy and black?

[theengineer]

I ve been working on a Wii laptop and i wanted it to display on a 7 inch car monitor and also have TV output. So i added a switch to the screen's ground so it could be turned off so the video could go out to a TV. But when it does the display is extremely distorted and black. Im assuming the switch should be on the video connection instead of the screen's ground?

Can you please post a picture of what the screen is doing and also of your setup?

You should either switch the power to the screen or switch the video signal to the screen. It's better to keep ground connected.
