I bought an activated 550 off Ebay it works but I have a problem. The problem is 4-1 was active in the previous location and 4-1 is our local FOX. I have tried hidding the channel but when I scan for locals 4-1 comes up with the wrong station identifier and no signal found. In the menu I can go to CH.35 our local 4-1 broadcast channel and get 97% signal. Suggestions appreciated.
