I'm not positive but I think the 54 remote shuts down the TV instantly but has a delay before the Hopper will shut down. Try it again and wait 15 minutes to see what happens.
Sounds like the remote is not set up correctly for your TV. There are multiple codes for each manufacturer and perhaps youi have selected one that does not work properly for the turn on.
I would try a different one: setting>remote>etc etc and try to skip the one you have currently selected.
Let us know how it comes out.
OOPS having a bad day, disregard previous post.
Have you checked to see if the remote is paired?
Try unpairing and repairing it?
Settings>diagnostics) top right side of screen.
anyways if this don't work there are a lot more knowledgeable folks here who will be glad to help.
