I was taking pictures out of my Sony camera and suddenly I realized that the flash of the camera is not working. Then I checked the screen it was showing an error message E: 901:2. I initialized the setting and it got restarted, but still Iâm not getting it. The error message disappears but the flash is not coming a yellow light is glowing in it continuously. Please help me by sending a better solution which will make my camera flash again usable. Thanks in advance.
