Help getting started with Roku devices, including setup, connecting your device to your TV, linking a Roku device to your account at my.roku.com/link, adding channels, subscribing to services, and more.
How do I deactivate a device that has stopped working to add a new device as to not take me over the 5 device limit?
Login to your roku account on a computer and unlink the device. I don't think you can deactivate a device, just unlink the device. There is no limit on the number of devices that can be linked to one account. I have 8 Roku devices linked to one account.
