My dvd's are all in black and white for some

hiya,

Try checking the connections between the dvd player and the tv, make sure they are fully pushed in.

If that doesnt work and you have a spare socket on the back of your tv try swapping the lead to that one.

I know that with scart leads if they arnt fully pushed in you will get a black and white picture.

I hope its thats simple..

Mike
