if there are any other fixings they will either be at the sides near the front behind an oval shaped plastic cap. Or there will two screws one either side of the control panel about 1 inch down. If none of the above apply then it is just a tight fit at the front where it enters the top of the control panel. I have known these to be difficult to remove I often find it works if you raise the back of the lid up then give the right rear corner a good nudge to the left. Cheers
