Perhaps your camera was set on "Manual" mode at a very high shutter
speed - in that case, the flash would fire but light from the flash
would reach only the very edge of the frame, if at all. The gap between
the curtains is very small at higher speeds, and the flash fires when
the first curtain reaches the closing edge, leaving only a narrow gap
where light from the flash would reach the film.
If the camera had been set on "Auto" mode, even with the display off, it
would (or _should_) have operated properly. (That's part of why OM-4's,
et al, drain batteries - portions of the circuit are always "on", ready
to operate.)
