Hi Ronni, Peter, Still no luck at all. I tried both suggestions and no change. I replaced the battery as it seemed low (just under 3V) and again no effect.
Looks like I need to get to an Apple repair centre, there should be one here in Singapore, never needed one before... Thanks to both of you for the suggestions.
