Selective TV broadcasts channels 4.1-4.3 on two different frequencies 22 & 33. The transmitter for frequency 22 quit working last night and will have to sent out to be repaired. The good news is that 33 is the better of the two frequencies and it is working fine. If you have lost your channels 4.1-4.3 because your tv was using frequency 22 just re-scan and your set will pick up frequency 33 which will show up on your set as 4.1-4.3 or 33.1-33.3.
