A Weird Fujifilm Battery Issue for X-series cameras
A defective battery can cause a Fujifilm X-series camera to start rattling and displaying blue, white or purple-striped screen in the LCD viewfinder.
After three months of troubleshooting, having the camera traveling back and fro between my studio and Fujifilm Italy tech support, they have been able to identify the issue: a defective battery didn’t send enough power to the camera, thus jeopardizing its operation.
