I am from Brazil and I own a SONY Cyber-shot DSC-W90. It was working fine until last week, when the E:91:01 error appeared on my screen and it is making me worried. The flash button also, does not work and it's icon keeps blinking on the screen. I can still take some pictures, but without flash. Do you know anything I can do to fix this? It's already out of the guarantee and here in my city, there isn't any authorized store to fix it. Thanks, Carolina.

Hi, you need to carry it to an authorized service center, because the problem is on the syscon main board.
