Chosen Solution
All of my pictures are too dark, and the camera’s flash is not working.
There are three common fixes to a non-working flash. First, make sure your camera is not in Silent Mode. Next, make sure your shutter is set to either auto or MSHTR. If you find that neither of those settings were activated, your solution might be as simple as opening the flash. Open the flash by pressing the P55 button, which is the small, spring activated push-lever located on the left side of the viewfinder.
I found on my fz300 if I have HDR mode turned on there is no flash function. So I turn off HDR when I need to use flash now.
FZ300 reset to factory setting and turned setting dial off of “iA” mode enabled the Flash menu item for me.
One other setting that will cause the Flash button to grey out is HDR. It is on screen 4 of the recording menu. Try turning it off and it might allow you to adjust your flash settings.
in my case i believe the preset i had that prevented the flash was the electronic shutter (actually, this and the seilent mode), so i turned it off and it worked. Luckyly enough the setup is on the same 4th recording menu as the HDR setting. Thanks for posting about this subject!
