You are a star - thanks! That did the job. When I took the switch off one of the browns wasn't connected, so I can only think it wasn't secured properly and popped out as I disconnected the front panel. That's why I didn't try what you suggested.
Anyway, learnt my lesson, will get a pro in next time.
Thanks again.
