How can I fix Sky HD box (amstrad)?

The box is working, tv can be viewed fine but the circle on front is always lit up blue, along with the play symbol etc on the front. It looks as if something is being viewed & recorded at the same time but I've checked the planner & nothing is being recorded. Ive turned on/off etc but nothing, they still remain lit. Any ideas will be greatly received, my dad is going to annoy me until I fix it!!
