Hello!
Based on what you've mentioned, it's likely that the issue is with the camera itself.
It's really disappointing to hear there's no repair service available in your area. However, there are a couple of things you can try before calling it quits. Firstly, visit the Fujifilm website and try updating your camera's firmware to see if that might fix the issue. Secondly, check if the problem persists with another lens. If it does, then it's probably an issue with the device.
If these methods prove unsuccessful, I suggest reaching out to Fujifilm customer support. They might provide some guidance on how to fix the problem remotely, or they could arrange for your camera to be shipped to a repair center.
