We used our MiBox 3 nearly every single day for well over a year, but I had it powered off for the past 6 weeks or so because we are remodeling.
Finally powered it back up about a week ago and it worked fine for a few days but then one morning we turned on the TV and there was no video from the MiBox. If I click around with the controller I can hear the menu sounds, so it's on and working - just no picture.
I've tried powering on/off a million times, bypassing my soundar and plugging directly into the TV, different HDMI ports, different HDMI cables... everything I can think of. None of it makes any difference.
I didn't update to Oreo but I'm wondering if maybe it automatically updated itself and that's why it won't work now? I did click on "Check Update" at one point during the few days it was working but it said there was no update available.
Anyone have any ideas? I'm totally lost.
