So, I have a Canon EOS 500n, I do not know much about photography and I didn't find this problem on the internet, so here it goes. Everything worked fine, but then, some time ago, the flash stopped working. What happens is when the camera pops up the flash, i makes a weird clicking noise and the no-battery icons flashes on the display. I already tried different batteries, new and used, and it makes no difference. I never dropped the camera, I always handled it with care so this started happening out of nowhere.
When trying to take an automatic shot, and it tries to use the flash, this happens. And also when trying to use the flash manually.
What could this be? A problem with the flash itself or an electronic problem with the whole camera? Everything else works fine.
Thanks for the help!
