Hello EcalVin
Thanks for reaching out here in the Community.
You've mentioned that you are powering your device from the TV's USB port. In some cases, the USB power provided by the TV is not sufficient to power the device. Even though your Roku device may appear to be working, running with insufficient power can lead to instability, crashing, and other unpredictable behavior.
Using the included power cord and power adapter, we suggest plugging your Roku into a working power outlet in the wall. Powering it through a power outlet in the wall has the additional advantage that your Roku player will not need to power up every time you turn on your TV.
Let us know if there's any difference after.
All the best,
Kariza
In addition to the reply from RokuKariza-D ...
The USB port on many TVs powers down when you turn off the TV. That means the Roku has to power back up each time you turn the TV back on. I wouldn't think this whould cause your Roku to require a full setup each time (my several Roku devices can be unplugged and still retain their settings when plugged back in) but it still might be worth while to try powering your Roku directly from your house power to see if this makes any difference.
Another thing to try as it has caused some people problems: If your Express has a Settings > System > Power option, try going there and disable Auto power savings > After 20 minutes of no interaction.
