Looks like mode/power switch failures are a common item across the entire E range. My problem started with the camera powering up in 'random' modes, which I ignored and it progresses to difficulty turning on.
E-510s, E-520s and E30s seem to have had very similar issues with the same control.
This control dial/power switch seems to be a weak point in the family design.
