First you need audio/video cords cords (or whatever theyre called.) They should be red, white and yellow. and probably look like this (link below). Some where on the back of your dvd player, and also on the tv, front or back there SHOULD be three or two holes, with corresponding colours. Just plug yellow with yellow, red with red and white with white. If theres no red, it doesnt matter.
Make sure you have the tv set to AV, and you dont need the aerial/antennae. either on the remote or the tv there should be a button saying "TV/AV" or "Video-TV" or "Input"
Just play around with hese, any tv in the world should have them.
This is what the cords look like.
This is the head of the cords, if you dont have them.
