I have been receiving all of the local channels through a digital converter box, ever since the conversion. I suddenly got “no signal” for one of the major stations, ABC 7 Chicago. It has been a few days now, with no change. I never before had any problem with reception of channel 7. Strangely enough, I still receive 7 in another room where there is a digital tv.
What could be wrong, and what should I do?
