Screen says "Not supported"?
I had the exact same problem with my older Visio 19" TV that worked for years with my Roku 3 and then all of a sudden "No Support" started displaying. I tried 2 or 3 different HDMI cables and each port. Tried resetting Roku to lower resolution via another TV. Multi reboots and resets ... nothing works.
Aussiebill, the "not supported" message is probably just showing up briefly when the Express reboots and likely doesn't have anything to do with the real problem. If you're using the TV's USB port to power the Express, try using a USB power adapter/charger from a phone or tablet that can supply at least 1 Amp plugged into the wall.
