You have to remove the outer casing, disconnect from the mains and leave it for at least 30 mins for the high voltage capacitors to discharge, two of the casing screws are (on mine they were) security torx screws, you can get the screwdriver adapter bits from Maplins etc. The bulb that Maplins sell for microwaves is the wrong size screw base, I had to get one from a specialist repair shop around £10 !!
