Only black and white on fujitsu 42" monitor with s-video

Bad conection. Check if you conect the video input or component input

Try connecting each monitor to a different desktop/laptop computer, to rule-out the possibility that the video-card on your own computer is the cause of the problem.

Have you got component cables specially for the wii? if so, then the screen should work fine.

As for audio. You'll need to use separate RCA's Red and white into the audio input if your using external speakers, if your using a surround sound amp then put them into the input there.

try changing the cables to s-video or hdmi to see if the problem solves. It could be defect or reverse component cables

On the video selection you have to go to HDMI and not video 5

panel is done. economical to repair. new panel is about 90 percent the cost of the tv new

When you start your computer, keep hitting the F8 key. you will get a menu that comes up.. Choose the VGA mode.. this will stop the computer from loading video drivers and will allow you to install the new monitor. 
Give that a try.. Hope it helps... let me know

use your remote and change to AV1 sys 1
