3 of the buttons on the remote control for my Hitachi 51f59 have stopped working after having head the set for only a couple of weeks. The problem buttons are the aspect button, the Day/Night button, and the fav. channel button. All the other buttons on the remote work fine, and the problem buttons always worked well previously. I know I've probably done something stupid to cause this. Or maybe something just went bad. Anyone have any ideas what the problem may be and how it might be fixed? Thanks in advance.

Problem resolved itself....sorry for the trouble.
