Fixed: Sony NEX 5r - camera error turn off then on

Have the camera in storage for some years now and tried to see if the long rest may have fixed it...it is still there displaying the "turn off then on" error message. Came accross the FRONT CURTAIN SHUTTER setting and set it to off and seem to have resolved the issue. Setting is set to on by default to minimize shutter shock in image captured - a working camera is still better ?
