Green tint on screen during dvd playback

I bought a Sony BDP-S370 blu-ray dvd player about 5 months ago and during playback of dvds there is a green tint at the bottom of the screen. It starts at the bottom and goes up about 10cm and goes all the way across also. Tried like 10 dvds and it is there on every one. It isn’t the tv because it’s not there on my sky hd and ps3.
