I don't understand

The colour information in component is carried by all 3 cables ? If you just plug the green cable in, you should see a green picture.

does it do this on all inputs ? what else have you tried connecting bar xbox ?

i've connected all 3 component connectors to dvd player all working fine just done 116 hrs turned projector on today it come on in b&w.so just to make sure the cable was not at fault tried my xbox component cable that was b&w then i've got a seperate cable spare which i then tried in the video input picture colour on and yes i did take the 3 component connectors out. LIke i said before i've not changed any settings so cannot understand why it has done this. cheers for your help

seems that way. good news is the hitachi customer support imo i found is excellent and very fast. called them before 10 or 12 on a weekday and they have some one to pick up the machine that same day with a 5day turn around

...Not true, with component video also referred to as a YPbPr or YCbCr signal, The Y component (the green socket) of this signal is the black and white information contained within the signal. The Pb and Pr signals are colour difference signals. The Y signal contains full bandwidth black and white picture information, and the colour difference signals contain bandwidth reduced colour information.

Reeceglen,

I'm afraid that I find it difficult to understand your post......... other then that you've got a black and white picture.

It's possible that the input of the projector is set to composite video. When you'd connect composite video you'd get a colour image, when you'd connect component video, you'd get a black and white image. Try checking what the input of the projector (you should find it in a menu) is set to.

Hello mate, I have the same problem with my Sharp PJ. Its ok with SVGA/D Sub, but erratically it goes B&W with composite or SVHS!!
