If the camera worked when you bought it in HK and now is faulty you may send to Hasselblad Service Centre - Shriro House at 11 Chang Charn Road .
They can help check the unit.
If you have not paid for it or can still get a refund - do it asap .
If it is second hand , then could be faulty as H4D 40 is still very new and unlikely for people to want to get rid of.
Ya, retiZach give Denis a call he is a nice and helpful man:thumbsup:.
