Got your camera handy?

There is a small square opening inside the card cover, at the top of the slots. See it?

Inside is a small pin, which is a trigger switch. Is that pin about 2mm from the "surface" of the opening?

You may have a faulty trigger switch, or an input card (that reads the various trigger switches in the camera) problem.

Unless its dirt clogging the pin, you may need proffesional help. Olympus should be able to tell you how to find a decent service shop.
