the little bulb holders just twist out, there are two on top and one in the middle behind the lcd screen, although this has its own green filter so never shines up bright unless you dismantle lots of things to get it out.
you don't need to remove the blue film with the pcb on it (i think). to take the green filter out you have to break out the white section on top as its melted in at several spots then just unpick the filter. if you do have to remove the film, the plug(s) on the bottom slide out then the film is held in place by little pins, just go slow because the copper tracks can be damaged.
