Amazon My Tv Guide Query
When you launch Prime Video on your device for the first time, you will be asked to sign in or register your device.
To register directly on your device, select the “Register on your [DEVICE]” option and follow the instructions shown on the screen.
You can also choose the “Register on the Web” or “Register on Computer” option. A 5–6 character activation code will appear on your TV or streaming device screen. Open Amazon at amazon.com/mytv on your computer or mobile browser, sign in to your Amazon account, and enter the displayed code to complete the setup.
Once registration is finished, your device will be linked to your Amazon account, allowing you to stream Prime Video content, access your purchases and rentals, and manage your viewing preferences easily.
