Today we experienced a power outage in our city [lasted about 2 hours]. Coincidental to that I noticed my tablo stopped working. I scanned the forum and found some post somewhere that suggested trying a new power adapter. The other person tried that and it failed. But I tried an old adapter I had in a drawer and it worked - the tablo is back up and running fine.
Don’t know who suggested changing the adapter but I would like to say thanks as that worked for me.
I thought the unit died as a few months back the Wifi failed and I thought the unit was soon to fail.
