We have a VIP222K at work and tonight when I came on I realized the remote for tv2 isn't controlling the receiver anymore. I went to tv1 and tried changing the address of the remote and it will not change it at all. I used the tv1 remote to change the address of that remote and it worked fine but the other remote won't. It still controls the tv and the buttons are lighting up so it's not the batteries. Please help. Twelve hours is a long shift.
