First thing to check would be the cables connecting the DVD player to the TV. Make sure they are fully plugged in at both ends, and that the TV is on the appropriate input. If everything has been verified, try a different cable or alternate connection as a test.
If you've connected the player to an analog TV using component video cables, make sure the unit is not outputting a progressive video signal. This will be indicated by "PROG." on DVD player display. If engaged, disengage by pressing the progressive button on the face of the unit.
