I posted this as a reply somewhere as well but wasn't sure if that thread was still active so I figured I should probably post a new one.
I have tried two different Roku Express' and they both keep rebooting.
I thought for sure with a new one (new to me anyways, a friend gave me it when they upgraded), the problem would be solved, but this one is even worse!
The old one would just randomly reboot every so often--this one will reboot & then shortly after reboot again and again and again, usually several times before it decides to behave again for an hour, maybe two-- sometimes not even.
When it starts cycling, I don't even get out of the loading screen most of the time, on the occasion I do, it restarts again as soon as I try to do anything!
This is driving me nuts, please help!
It is not connected to the TV USB, it has it's own power source.
It's model 3930x
