Hello Mollipatton. At this time the 1287 is a known issue that the Engineer Team is aware of. If the work around did not work. We will need to wait for them to resolve this with a software update. We do not have a specific date for the fix release, but we do greatly appreciate your patience.
With the remote, I will be more than happy to work on that with you. If you have the original TV remote, you can go to Menu>Settings> Remote Control> TV> Teach Commands> Add Commands
Place the remotes as displayed on the screen, and try to teach the DISH remote the TV remote commends if previously the Wizard was not successful.
