Shutter button not working

SOURCE: No picture is taken when shutter release button is pressed

Are those NiMH batteries? Have you tried resetting the camera? If no standard way, just take out batteries for a few minutes, the more the merrier, let the tension build, and replace them. Try tapping on the lens area, it might loose something up. Best I can do, know it aint much ;] Good luck!

if you see no reation of the pressing of the button i.e. no focusing, no error message nothing , then most probably a simplest problem , the shutter release button may not be working for few reasons : 1) defective switch. 2) defective flex cable. 3) camera exposed to some physical jerk or dropping resulting into disalingment between inner switch and the shutter release button.

'I have opened the camera up and looks OK' How can you tell? what you have done is negated any chance of as repair or replacement. But a new camera?

I also dropped my Fuji F30.
The half-press of the shutter didn't work anymore.
I bought a triwing / triblade screwdriver (about 5 euros) to open the case.
The flatcable running from the knobs on top of the F30 to the main print was a bit loose. After reconnecting it, the shutter button was fully functional again.
It seems that from the backside the most 3 three wires in the flatcable are for the shutter, so if your cable is also a bit loose, this might solve the problem.

NB Remember to only open the backside of the casing, there is no need to open the lens-side. Opening and closing the backside is really easy and could be done by anyone with the right tools. (read screwdrivers...)

Try doing a reset in the camera tools somewhere, this fixed a similar problem I had.
