It just keeps trying to find focus. If I press the half-click focus button I hear the motor moving and the numbers on my lens go from smallest to infinity and stop. If I press the half-click focus again it goes from infinity back to the smallest number (0.5meter) and stops.
If I repeat the above exercise 20-25 times, then maybe 1 time it will lock the focus nicely and let me take a good picture. The same thing happens no matter the scene, object or light conditions.
I have tried two different Nikon lenses that focus well on my other camera. Even the D5500's View Finder works perfectly, the issue only happens during the live view.
I have tried cleaning the contacts, the sensor looks clean too. The camera is on the latest firmware too, the battery is full. The picture quality is great (otherwise).
No warranty, I bought a used camera. Was wondering if I could fix it.
