Sounds like the flash is defective.
If you have had it only about a month, it is still under warranty.
It is good that it happened while still covered by warranty.
Send it for repairs.
That what warranty is all about.
camera worked fine for about a month, then the flash started working intermittently. Started trouble shooting, and in a completely dark room, camera is in Program Auto (auto exposure with adjustable settings), and the flash is set to alway on, out of 10 pictures, 7 would be no flash, completely black pictures, the other 3 would have flash and look fine(I waited after each picture before taking the next, to make sure the flash was ready). I've chatted with sony online, they suggested initiliazing the camera, which I did, still same results. Battery is completely charged. And now I can't get the flash to work at all, and sony online support now says to send the camera in for repair.
Anybody else have a problem like this??
