In-line fuse or not, (no power issue) - update
Turns out it's not a fuse or a power problem, when I removed and replaced the fuse (that didn't appear blown) all I did was reset the power and force a hard reboot. The MyGig is actually not powering down properly (I can hear the hard drive running after shutdown) and when I start up again it fails to boot up. It just sits there with a blank screen and all the hard buttons are inop (that's why I thought it wasn't getting power).
I thought I had read others had this same problem (MyGig not shutting down properly), but I can't seem to find the thread now. Anybody? Is there a hard key sequence to force a reboot? I fear that I'm destined for an appointment with the dealer to replace the unit, just trying to see if there's any way around a remove and replace (other than me pulling the fuse to force a hard reboot every time).
