There are some musical tones accompanying the dancing R O K U letters when doing a full reboot. This happens when starting up from a full powered-down condition. If you are powering from the USB port on the TV, it may be that the port itself powers down when the TV is off. There MAY be a setting on the TV to control this, or you can instead power the Roku by plugging it into your house power using a USB power adapter so that the Roku stays booted up. If you don't have a Roku adapter handy, one from some other device can be used, just be sure the fine print on it says its 5v output is at least 1 amp (1000 milliamps). More amps is OK, the Roku will only draw what it needs.
