samsung sgh d900i bluetooth broken???

i have to got a Samsung SGH D900i, i recently tried to use my bluetooth and it says "bluetooth activate error" i have tried everything i know...turning off/on the phone, master reset, etc i was thinkin it could always be a problem with the actual phone.. maybe a pcb fault, however i wanted to ask for professional advice before i hand in the towel and call manufacturer.... :s
