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 you may be in the wrong shooting mode, for that setting.
Or, you may have a feature enabled, that makes the B&W mode unavailable.
One way out of this is to try other shooting modes.
Another way to deal with it is, to do a Factory Settings Reset of the camera, so that all its settings are back to the factory-issue defaults.
I am looking up how to do that factory-reset, and will post again within some minutes. (Meanwhile, if you can tell me what shooting mode you are trying and failing to enable B&W mode in, it may help me advise you.)
The factory settings reset on this model, can be done by holding down 2 buttons at the same time for at least 2 seconds continuously.
The two buttons are marked with green dots. The two buttons on this model, are the +/- and the AF button.
Good. That matches what I said,
you may be in the wrong shooting mode, for that setting.
Please rate my answer and my work on your case. A five-star rating would best express appreciation.
