Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think I can guide you to a solution to the problem, troubling as it may seem.
Some questions about the problem:
- how old is the camera in question, please?
- and, when did the flash last work OK?
- and, is it an add-on flash unit, or is it a pop-up or built-in flash unit ?
