Last year around October I sent my fujifilm x-pro1 for repair to install a new OVF as the previous one was not working, and my camera was returned working again.
I did not start using it again until New Year, and since then am having a recurring problem with the camera:
I put in a fully charged battery, turn on the camera and it works fine as I can take many pictures. I turn if off. Wait a few seconds. Turn it on again but this time it is frozen blank on the optical view finder and none of the controls (turn off/on, view mode etc...) can change this frozen blank state, nor can I turn off the camera.
What is happening ? The only solution I see is taking out the battery, waiting a long while (hours/days), and put in a new battery and see if it turns on again.
Hopefully it is not a big issue, but I need to have this sorted out for me to be able to enjoy the camera as before.
