Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
Bob, the original remote part is no longer available because the player itself is so old.
You can purchase a generic replacement model here: http://amzn.to/2c1WIds
For the cost though, I'd consider simply replacing the entire player instead, you can get a brand new player with update features and fresh warranty (plus the remote) for less money: http://amzn.to/2c1YLOi
The expected life of these players is only about 5 years, and yours is well past that and would not be expected to last much longer, so going for a new one would be the more practical investment.
Do you need more help with this?
