When I push the channel up or down button on the remote, the channels keep changing and the receiving light keeps flashing. The only way I can stop it from changing channels is to push any other button on the remote. The volume button, on the remote, stops "channel changing" and the light on the front of the sat 60 from flashing. I recently changed out the hard drive about six weeks ago, but everything was working good untill to day. I should mention that I have a spare remote control for this unit and the same thing happened with to the sat 60 with it. I also did a reset of unpluging the receiver.

Any help would be greatly appreciated. Thank you
