Colour Radio-No Video From DVD player

My Panasonic F87 dvd player has stopped giving me a video signal. When a movie dvd is played all I get is an audio playback. The CD function is not on and the TV is set to the correct channel. I think this points to a problem with the video laser. The warranty has run out. I would like to know if there are any things I can check. I am an electronics tech that works on industrial equipment but have little experience on home electronics.
