Thank you for your reply Bolter. the magnet on the upper body is there. I just purchased a brand new trigger. An invert mini roller ball one i think it was. The magnet is there and I've been adjusting it to see if i get any response. I've not tried what you said about the fine movements with my finger covering the eyes. I will give that a go. Ive just seen that the cable going from the battery to the board is quite lose the red cable. Some of the steel wire has broken away. I have ordered a new one of these. The marker would power up but could this possible be the issue?
