Do you see any channels [as a glimpse], during auto-tune. If you see them for a moment during channel auto scan, and do not store them in the TV memory, after the channel scan has been finished; the fault is with the TV itself. If you do not see that glimpse of programs during channel auto scan, there are two possibilities.
1. The tuner of the set is faulty.
2. The set do not get any signal to process [might be antenna].

yes the tv is telling you it either has no signal or bad input in most areas now you need above 33mhz to receive a reception on tv
SOURCE: I can't get channels during antenna scan on my Vizio TV, any ideas?
Main system control memory IC fault. This IC can be located very near to the main system control IC at its main board. Will look somewhat like this.
