For our model 48339 Creda Concept Solar Plus, I've now noted down what to do - first switch off the cooker min switch and ensure no-one will interfere to switch it back on!
Pull the cooker out from adjacent units to allow all-round access.
Remove the many screws holding on side panels (not all are obvious!) - care, not all are identical.
Undo the top hob portion (halogen rings and all) as a unit to allow access to the rear of the control panel.
Remove and replace the 21 inch slim 13W fluorescent tube (no fancy part number!) to bring back all the lights.
However - don't tackle this job if you are not reasonably careful and methodical - get someone who is!
