Hi Jim,
Thanks for your post. Let's try some troubleshooting steps to resolve the issue.
Please restart the Fire TV Stick by unplugging it from the power socket, after 30 seconds, plug it back in. Also check the HDMI port, make sure it is not corroded and try inserting into HDMI Arc as it is the preferred one.
Also make sure that you are entering correct Amazon credentials while trying to register your Fire TV Stick. Try resetting the password by going through our password assistance process on our website.
To reset your password once again:
- Go to Password assistance.
- When prompted, enter the email address or mobile phone number associated with your Amazon account and select Continue. We'll send you an email or SMS (depending on the verification method you've chosen) containing a One Time Password (OTP), to authenticate your request.
- Enter the OTP you received and select Continue.
- Create a new password.
- As soon as you've created a new password, it's active. Your new password is for all Amazon-related accounts associated with the same email address.
- After resetting your password try to register your device
If the issue persists, please consider resetting the device to it's factory defaults. To factory reset your Fire TV device using your remote:
- Press and hold Back and right side of the navigation circle together for 10 seconds.
- On the TV screen, choose to continue or cancel the factory reset. If you don't choose, the device resets automatically after several more seconds.
If you still have issue, please contact the Fire TV support channel for more assistance. Getting Started : Amazon Digital and Device Forum (amazonforum.com)
