I was using my camera and the viewing screen went blank. The battery is fine, there is power... you can see info on the small view finder but nothing on the screen

I don't think anything is wrong with your camera. Just check the Manual.
Your camera has a view finder, to make pictures. Yes the little screen on the top left (Backside) As an extra the camera has live view, that can be switched on and off. because the live view consumes lots of power, it is advised to use the view finder. If you want to switch it on, you can do so in the settings menu. There go to the live view en switch it on.

Think that you might have accidentally pressed the DISP or DISPLAY button on the back of your camera. This manually turns the LCD display on and off to save batteries. You would then use the optical viewfinder in its place. To turn the screen back on, just press the DISP button one more time.

Try pressing the display button.

There is a small knob to adjust the image through the view finder.

Refer to the manual if you cannot find it.

Press the button marked "evf". That should move the image to the big LCD for shooting.

Look fo the switch that has two setting. one of them will say LCD and the other Migt EVF if you have a view through your view finder this is your problem.

i have same problem

call Fuji and tell them that you would like to send in your Finepix to see if the cheap/defective SCR chip was used in your model. If so, they will fix for free.

could u take pics are they ok on pc or they are also blank black pics if thats the case then my friend it seems like ur CCD has stopped working , there is strong chance of that , does it have any CR type battery to be replaced pls check some cameras do have those batt otherwise check its CCD from service center i am pretty sure abt that

Is the battery dead? Try taking it out and charging it, then put it back into the camera.

Also, you can try using another battery of the same type.
