  1. I’ve done everything to fix this usb needs more power. Gone through all the steps including roku support . Is there a physical fix to this problem? Ready to put a sledgehammer through this unit. It’s been like this shortly after getting the set. Now it has gotten worst. You have to hit the arrow back button so you can move through the menus. You can move maybe three times before hitting this button again, also it takes of running through your movie selection.
