Change your tv colour System in to Auto mode.It will adjust in menu.Mostly DVD recorded on NTSC 3.58 colour system.After adjust on auto mode Colour will come.

try going under setting ans see if you can find anything on color

Ok,
I'm not sure what you mean by digibox. Under what conditions are you able to see things in color? Is a digibox a seperate device you can get to work with the same connection as your player? If one device displays color on the same connection and another doesn't then that seems to rule out the television being the problem. Can you clarify a little more?

You need to convert avi files to dvd format before burning, otherwise the player won't recognize them. Google "avi to dvd" and you'll find a number of free or pay programs that will do the conversion for you.

My DVD player is Sony DVP-NS50P, it can not play some dics (not in USA). You can help to unlock it !

Thank you very much.

If you are playing different region dvds, they can be of different color formats also
(US = NTSC, Europe = PAL). If your television is not multi-format then non-compatible
DVDs will play black and white. The solution is to purchase a mutli-format TV (accepts
both PAL and NTSC formats)

try pal-ntsc anyway

If you are using the s-video jack to connect the DVD to the TV, the jack could be loose or the wire could be bad. The s-video cable has 2 signals, the black-and-white (luminance) and the color (chroma). If the chroma signal is not getting through, the picture will be in black and white.

if you are using composite cables (yellow,red & white), make sure your yellow (video cable) is into the yellow output. if you plugged the wire into the green on the back of the dvd it will give you a black & white picute. But if it is in the yellow then you most likely have a problem with the dvd player that will need to be taken to a service center.
