Question about Vizio GV46L 46 in. LCD Television
The DTV input in my GV46L stays black and when I try to go to the menu the tv buttons have to be pressed hard. In the end I can't scan for channels because I can't reach dtv menu. So I'm left with a complete black screen. What might be the issue? We've had it for about 4 years. This had been going on and our costco insurance covered it, they changed some type of antenna before. But on regular TV input it works just fine.
You don't say what you are trying to input but take note that your model does not have a digital tuner on the DTV input. If you use a digital OTA antenna, the signal must first go through a digital converter or tuner before it goes into the DTV input. The DTV/ANT input is only cable ready. There is no digital tuner in the TV to activate the DTV menu.

SOURCE: Scanning dtv channels
go to menu setup and do the full system reset setup option... Then before you scan for channels make sure it is set to cable... This fixed the problem for me.
