SOURCE: Why won't my new Vizio DTV work on an antenna

Do you have the antenna aimed correctly and the correct antenna for the distance between your location and the stations? Check antennaweb.org and tvfool.com for the directions to the stations you should be able to receive. Antennaweb assumes an external antenna and is very conservative in the station list. TVfool gives the stations you should get with various different types of antennas. Tall trees and buildings will block signal strength so consider the environment around you.

With digital signals, if you do not have enough signal strength for a given tuner, the channel will not come in. An amplifier may help you get the signal, particularly if the signal is shared to several devices. Failure of an amplifier or lightning surge protection can stop the signal from reaching the TV. A surge through the antenna can damage the tuner.

A damaged cable can also be a source of a problem. Check the outside portion of the wire as well as the interior wires. Replace any that have damaged insulation or ends.

For this TV, if you have done a channel scan with the TV set to the Input TV/DTV, and the Signal Source set to Antenna. Turn the antenna and then set the Additional Scan to On. (Menu > TV > Channels > Additional Scan.) Then do another channel scan.

The DTV input in my GV46L stays black. Why?


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.

Try the recommendations in a document posted on the FCC site (http://hraunfoss.fcc.gov/edocs_public/attachmatch/DOC-291403A1.doc)

Also be aware the several stations have had problems with the transition. Some changed frequencies on which they were transmitting and encountered area coverage issues that didn't meet their expectations. They have been working with the FCC to remedy the problems and many stations have temporarily increased output power to compensate for the issues. Some of these stations may be difficult to receive and you may need to get larger antenna. If you are still having problems call the FCC DTV transition hotline at 1-888-CALLFCC (1-888-225-5322) or the TV station for advice.

Have a vizio lcd tv . can not get any channels today with the switch over to digital. i use an antenna


Your TV probably does not have a digital tuner connected to the DTV/ANT input. Mine didn't. I had to connect the digital antenna to a digital converter box THEN go to the DTV/ANT input. Only then would it activate the DTV menu and allow me to scan for channels. If your TV worked fine with Cable TV connected to the input, it was because your signal was coming from the digital tuner in your DVR, or your cable provider was sending you an unscrambled digital signal (not likely).
I used a digital converter box I had purchased with the government $40 coupon back in 2009 but the resolution is only 480 and looks like a Monet or Renoir. Now I am shopping for a high quality tuner.

Follow up on No DTV tuner after unplugging it a month for vacation. After I let it set plugged in for about 2-3 days it started working normally again and has been fine ever since. I hope this may help someone else. Genez 6-7-09
