What kind of remote are you using? or better yet, whats the number/colour of the tab on the bottom?

If you're using the #1/green one, take the antenna off the back of the receiver. If you're using the #2/blue one, push the menu button twice, pull the battery cover off, switch the A/B tab over to the other one, and finally hit the record button to save the new band onto your receiver.'

edit: Actually; dont hit the menu button twice, push the system Info button from the front panel. This is where you'll save the new code, and not affect another uhf controlled receiver.

If it took a 'HOURS' to figured out your issue, than their was probably a bigger problem.

P.S. I'm not referring to the equipment.
