If your TV is telling you the Luminoodle is overloading it's USB port, it means the port doesn't have an output of 5V, 1A which is what the Luminoodle requires. You have a few options. The first is to plug the Luminoodle into a USB port on a different device with a USB port near your TV, ideally one that you turn on and off with the TV (Xbox, cable box, etc.). The second is to turn the brightness down on the Luminoodle (plug it into a different USB port so it turns on, turn the brightness down, then plug it into your TV to see if it works). The third option is to plug the Luminoodle into a USB wall adapter. You'll probably need a USB extension cable as well. This, of course, means the Luminoodle will stay on all the time unless you manually turn it on and off with it's wireless remote.
It's definitely not ideal when the TV's port can't support the Luminoodle's power requirements; please don't hesitate to send us an email at firstname.lastname@example.org with any questions or clarifications!
