hi i have a luminox lx760 camera?

This camera may be faulty. If so you should get your money back. If they refuse then the impotant lesson here is never to buy anything from them again, and write to tell them that.
On a more positive note, is the battery OK. Takes a fair amount of power to fire a flash. Sometimes the camera will work, but the flash is just too much. I don't know this camera, but if you have only had it for two days, then it does not sound right.
