E91.01 Error E91.01. Initilize solves the problem for the moment, but than the flash is not in use after that. How can the problem be solved so you can use the flash again, on a normal way? The camera is not even 1 year old. Go back to the shop, as guarantee? I can not miss my camera for a week, who knows if the problem can be solved permanently and how long it will take? Thanks!

Hi!
Try initializing the camera. Error 91 is a flash error in Sony cameras. It is probably a dead flash fuse on the motherboard (most common problem) or a faulty flash board. If you have a multimeter, I can help you locate and test the fuse and if you have a soldering iron - even fix it. My e-mail is [email protected]. Otherwise, you should contact your local Sony service center or other local camera service center.

Hope this helps!
