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 option 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 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 also add an in-line on/off switch so you may want to consider upgrading to Luminoodle Color Bias Lighting that has a built-in switch.
The third is to trim some LEDs off the end of the strip until it illuminates (only works with the white TV backlight, if you have the color backlight, don't do it!). We don't love this one because it means you have to have a shorter strip and it's hard to know exactly how much you'll need to trim so this is really a last resort.
It's definitely not ideal when the TV's port can't support the Luminoodle's power requirements; please don't hesitate to reach out with any questions or clarifications!
