Hi there and welcome
can you do the following please
Remove the power to the TV (so unplug it from the power socket) and remove the firestick
Wait 5 minutes
Connect the power to the TV and turn it on
Wait 5 minutes, connect the firestick and tell me please if it then works correctly Irene.
ok, can you try a different HDMI port on the TV, does it then load?
It is the internal memory in the fire stick that has faulted, it is not able to load the firmware
I am really sorry about this and you are going to have to return the stick to have it replaced. It will be covered by the warranty if this has not expired, and the replacement will be done at no cost to you.
I am really sorry about this, and if you have problems, or would like any additional information or assistance, please do not hesitate to let me know.
And if you can take a second to rate my service by clicking one of the stars at the top of the page, then submit, that would be greatly appreciated.
